However, there is insufficient reliable information available about the safety of bilberry when used in medicinal amounts during pregnancy and lactation; avoid using.
POSSIBLY SAFE ...when non-contaminated species of spirulina blue-green algae are used orally and appropriately (91713). The blue-green algae species Arthrospira platensis has been used with apparent safety in doses up to 19 grams daily for 2 months, or 10 grams daily for 6 months (18296,18300,18306,75944,91705,99703,104567,109965). The blue-green algae species Arthrospira fusiformis has been used with apparent safety in doses up to 4 grams daily for 3 months, or 1 gram daily for 12 months (15782,91717). Another blue-green algae species, Arthrospira maxima, has been used with apparent safety in a dose of 4.5 grams daily for up to 12 weeks (18297,99654,99655,102688). ...when non-contaminated, non-toxin producing strains of blue-green algae from the Aphanizomenon flos-aquae species are used orally and appropriately. Doses up to 1.6 grams daily have been used with apparent safety for up to 6 months (14842,18310). Some blue-green algae species can produce toxins called microcystins. According to the World Health Organization (WHO), the tolerable daily intake of microcystins in adults is 0.04 mcg/kg (96549).
POSSIBLY UNSAFE ...when contaminated blue-green algae are used orally. Blue-green algae can be contaminated with heavy metals (including mercury, cadmium, lead, or arsenic), neurotoxins, and toxic microcystin-producing cyanobacteria such as Microcystis aeruginosa (9171,75966,91704,91711,96550). Microcystins are most commonly reported in the blue-green algae species Aphanizomenon flos-aquae harvested from Upper Klamath Lake in Oregon. The Oregon Department of Health has set a limit of 1 mcg of microcystin-LR equivalents per gram dry weight of blue-green algae, assuming consumption of about 2 grams/day by adults (91704,91713). However, many samples of Aphanizomenon flos-aquae have been reported to contain higher levels than this (9171,91704). According to the World Health Organization (WHO), the tolerable daily intake of microcystins in adults is 0.04 mcg/kg (96549). When consumed orally, microcystins accumulate in the liver, binding to and inhibiting protein phosphatases, causing hepatocyte damage and possible tumor promotion (9171). Aphanizomenon flos-aquae can also produce neurotoxic compounds that may be present in supplements containing this organism (91704).
CHILDREN: POSSIBLY UNSAFE
when blue-green algae products are used orally.
Blue-green algae can accumulate heavy metals such as lead and mercury (91704,91711). They can also contain toxic microcystins produced by contaminating species of cyanobacteria such a Microcystis aeruginosa (91704). Children are more sensitive to poisoning by microcystins (3536). The Oregon Department of Health has set a limit for microcystins of 1 mcg per gram dry weight of blue-green algae, but some countries have set very low exposure limits of 0.2 mcg per day and 0.8 mcg per day for infants and children, respectively (91704).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
Some blue-green algae products, specifically those of the species Aphanizomenon flos-aquae, have been found to contain low amounts of beta-methylamino-L-alanine (BMAA). BMAA is associated with neurodegenerative diseases, and breast milk has been shown to be a potential source of BMAA exposure in infants (96550).

PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in amounts commonly found in food (4912).
Carrot essential oil, extracts, and food additives have Generally Recognized as Safe (GRAS) status in the US (4912).
There is insufficient reliable information available about the safety of carrot when used in medicinal amounts during pregnancy and lactation.
POSSIBLY SAFE ...when applied topically to the skin. A gel containing 1% Fucus vesiculosus extract, applied to the skin twice daily, has been used in clinical research with apparent safety for up to 5 weeks (12799).
POSSIBLY UNSAFE ...when used orally due to its iodine content and possible heavy metal content. Fucus vesiculosus contains up to 0.05% iodine or 226 mcg/gram dry weight (12789,74217). Ingesting more than 150 mcg of iodine daily can cause hyperthyroidism or exacerbate existing hyperthyroidism (12788). Fucus vesiculosus can also contain heavy metals, including cadmium, arsenic, and lead, and can cause heavy metal nephropathy (12789,12800,74213).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally because it may contain iodine and heavy metals (12789,74213,74217); avoid using.
LIKELY SAFE ...when used in amounts found in foods. Laminaria has Generally Recognized as Safe (GRAS) status in the US (94048).
POSSIBLY SAFE ...when iodine-reduced laminaria supplements are used, short-term. Iodine-reduced laminaria powder has been safely used at doses up to 6 grams daily for up to 8 weeks (109572).
POSSIBLY UNSAFE ...when used orally in medicinal amounts. The average laminaria-based supplement might contain as much as 1000 mcg of iodine. Ingesting more than 1100 mcg iodine daily (the tolerable upper intake level) can cause hypothyroidism, hyperthyroidism, or exacerbate existing hyperthyroidism (9556,94046). In addition, some laminaria supplements may contain arsenic (645,10275,15588). There is insufficient reliable information available about the safety of laminaria for its other uses.

Concomitant consumption of apple juice can significantly decrease oral absorption and blood levels of aliskiren.
Details
Pharmacokinetic research shows that coadministration of apple juice 200 mL along with aliskiren 150 mg decreases the bioavailability of aliskiren by 63% (17670). Apple juice seems to inhibit organic anion transporting polypeptide (OATP), which is involved in drug uptake in the gut, liver, and kidney (7046,94413). It is thought that apple juice might affect OATP for only a short time. Therefore, separating drug administration and consumption of apple juice by at least 4 hours might avoid this interaction (17603,17604).
|
Theoretically, consuming apple juice with antidiabetes drugs might interfere with blood glucose control.
Details
Clinical research suggests that consuming apples or drinking apple juice can raise blood glucose levels, with the effects of drinking apple juice being more significant than consuming apples (31699).
|
Consuming apple juice with antihypertensive drugs might interfere with blood pressure control.
Details
Some clinical evidence suggests that consuming apple and cherry juice can increase blood pressure in elderly patients (31680).
|
Concomitant consumption of apple juice can significantly decrease oral absorption and blood levels of atenolol.
Details
Pharmacokinetic research shows that coadministration of apple juice 600-1200 mL decreases levels of atenolol by 58% to 82% in a dose-dependent manner (17999). Apple juice seems to inhibit organic anion transporting polypeptide (OATP), which is involved in drug uptake in the gut, liver, and kidney (7046). It is thought that apple juice might affect OATP for only a short time. Therefore, separating drug administration and consumption of apple juice by at least 4 hours might avoid this interaction (17603,17604).
|
Concomitant consumption of apple juice can significantly decrease oral absorption and blood levels of fexofenadine.
Details
Pharmacokinetic research shows that coadministration of apple juice 400-1200 mL along with fexofenadine 60-120 mg decreases bioavailability of fexofenadine by up to 78% (7046,94413). Coadministration with smaller quantities of apple juice (150 mL or less) does not appear to affect the bioavailability of fexofenadine (94421). Apple juice seems to inhibit organic anion transporting polypeptide (OATP), which is involved in drug uptake in the gut, liver, and kidney (7046,94413). It is thought that apple juice might affect OATP for only a short time. Therefore, separating drug administration and consumption of apple juice by at least 4 hours might avoid this interaction (17603,17604).
|
There is some concern that concomitant consumption of apple juice might decrease oral absorption and blood levels of lithium.
Details
In one case report, a patient had an undetectable serum lithium level when lithium citrate was administered with apple juice. When lithium was administered with an alternative beverage, the lithium level became detectable and the patient demonstrated clinical improvement (105342).
|
Concomitant consumption of apple juice can significantly decrease oral absorption and blood levels of OATP substrates.
Details
Research shows that consuming apple juice inhibits OATP, which reduces bioavailability of oral drugs that are substrates of OATP (7046,17605). Fexofenadine, atenolol, and aliskiren are substrates of OATP. Clinical research shows that coadministration of apple juice decreases bioavailability of fexofenadine by up to 78% (7046,94413), aliskiren by 63% (17670), and atenolol by up to 82% (17999). These effects appear to increase with larger quantities of apple juice. It is thought that apple juice might affect OATP for only a short time. Therefore, separating drug administration and consumption of apple juice by at least 4 hours might avoid this interaction (17603,17604).
|
Theoretically, combining Ascophyllum nodosum with amiodarone might cause excessively high iodine levels.
Details
Ascophyllum nodosum contains iodine (94997,95000,95102), although the bioavailability of iodine from Ascophyllum nodosum is lower than that of potassium iodide (94997). Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use might increase the risk of having excessive iodine levels and adversely affecting thyroid function (7135,17574). Monitor thyroid function.
|
Due to its iodine content, Ascophyllum nodosum might alter the effects of antithyroid drugs.
Details
Ascophyllum nodosum contains iodine (94997,95000,95102), although the bioavailability of iodine from Ascophyllum nodosum is lower than that of potassium iodide (94997). Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Ascophyllum nodosum while using antithyroid drugs could alter the effects of the antithyroid drugs (17574).
|
Due to its iodine content, Ascophyllum nodosum might alter the effects of thyroid hormone.
Details
Ascophyllum nodosum contains iodine (94997,95000,95102), although the bioavailability of iodine from Ascophyllum nodosum is lower than that of potassium iodide (94997). Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Ascophyllum nodosum while using thyroid hormone could alter the effects of thyroid hormone (17574).
|
Theoretically, barley might decrease the clinical effects of triclabendazole.
Details
Animal research suggests that a diet supplemented with barley can reduce the bioavailability of triclabendazole when taken concomitantly (23884). This effect has not been shown in humans.
|
Theoretically, bilberry fruit extract might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, bilberry leaf or fruit extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Details
Animal research suggests that bilberry leaf extract might have blood glucose-lowering activity (1264). Also, one small clinical trial in patients with type 2 diabetes shows that taking bilberry fruit extract 470 mg as a single dose prior to an oral glucose tolerance test lowers plasma glucose levels when compared with placebo (91507).
|
Theoretically, bilberry fruit extract might decrease levels of drugs metabolized by CYP2E1.
Details
Animal research shows that exposure to small concentrations of bilberry extract in drinking water for around one month increased CYP2E1 activity by 31%. However, exposure over a 2-month period did not increase CYP2E1 activity (103191). This effect has not been reported in humans.
|
Theoretically, bilberry fruit extract might reduce the efficacy of erlotinib.
Details
In vitro research suggests that bilberry fruit extract and its constituents, delphinidin and delphinidin-3-O-glucoside, inhibit the activity of erlotinib (97031). This interaction has not been reported in humans.
|
Theoretically, spirulina blue-green algae might increase the risk of bleeding if used with other anticoagulant or antiplatelet drugs. However, this is unlikely.
Details
Spirulina blue-green algae have shown antiplatelet and anticoagulant effects in vitro (18311,18312,75892,92162,92163). However, one preliminary study in 24 patients receiving spirulina blue-green algae 2.3 grams daily for 2 weeks showed no effect on platelet activation or measures of clotting time (97202).
|
Theoretically, taking blue-green algae with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Human research shows that spirulina blue-green algae can have hypoglycemic effects in patients with diabetes, at least some of whom were using antidiabetes drugs (18299). However, blue-green algae does not seem to improve glycated hemoglobin (HbA1c) levels in patients with diabetes (102689,109970). A meta-analysis of animal studies also suggests that spirulina blue-green algae have hypoglycemic effects (109970).
|
Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.
Details
|
Theoretically, combining Fucus vesiculosus with amiodarone might cause excessively high iodine levels.
Details
|

Details
|
Due to its iodine content, Fucus vesiculosus might alter the effects of antithyroid drugs.
Details
Fucus vesiculosus contains high concentrations of iodine (7135). Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using antithyroid drugs could alter the effects of the antithyroid drugs (2138,17574).
|
Theoretically, concomitant use of Fucus vesiculosus with CYP2C8 substrates might increase the risk for adverse effects.
Details

|
Concomitant use of Fucus vesiculosus and lithium has resulted in hyperthyroidism.
Details
There is a case of hyperthyroidism occurring in a patient taking Fucus vesiculosus and lithium (74217). Monitor thyroid hormones closely in patients taking lithium and Fucus vesiculosus concomitantly.
|
Due to its iodine content, Fucus vesiculosus might alter the effects of thyroid hormone.
Details
Fucus vesiculosus contains high concentrations of iodine (7135).

Turmeric has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
Details
In vitro research suggests that curcumin, a constituent of turmeric, inhibits mechlorethamine-induced apoptosis of breast cancer cells by up to 70%. Also, animal research shows that curcumin inhibits cyclophosphamide-induced tumor regression (96126). However, some in vitro research shows that curcumin does not affect the apoptosis capacity of etoposide. Also, other laboratory research suggests that curcumin might augment the cytotoxic effects of alkylating agents. Reasons for the discrepancies may relate to the dose of curcumin and the specific chemotherapeutic agent. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects (96125). More evidence is needed to determine what effect, if any, turmeric might have on alkylating agents.
|
Taking turmeric with amlodipine may increase levels of amlodipine.
Details
Animal research shows that giving amlodipine 1 mg/kg as a single dose following the use of turmeric extract 200 mg/kg daily for 2 weeks increases the maximum concentration and area under the curve by 53% and 56%, respectively, when compared with amlodipine alone (107113). Additional animal research shows that taking amlodipine 1 mg/kg with a curcumin 2 mg/kg pretreatment for 10 days increases the maximum concentration and area under the curve by about 2-fold when compared with amlodipine alone (103099).
|
Turmeric may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, research is conflicting.
Details
Curcumin, a constituent of turmeric, has demonstrated antiplatelet effects in vitro (11143,81204,81271). Furthermore, two case reports have found that taking turmeric along with warfarin or fluindione was associated with an increased international normalized ratio (INR) (89718,100906). However, one clinical study in healthy volunteers shows that taking curcumin 500 mg daily for 3 weeks, alone or with aspirin 100 mg, does not increase antiplatelet effects or bleeding risk (96137). It is possible that the dose of turmeric used in this study was too low to produce a notable effect.
|
Theoretically, taking turmeric with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Animal research and case reports suggest that curcumin, a turmeric constituent, can reduce blood glucose levels in patients with diabetes (79692,79984,80155,80313,80315,80476,80553,81048,81219). Furthermore, clinical research in adults with type 2 diabetes shows that taking curcumin 475 mg daily for 10 days prior to taking glyburide 5 mg decreased postprandial glucose levels for up to 24 hours when compared with glyburide alone, despite the lack of a significant pharmacokinetic interaction (96133). Another clinical study in patients with diabetes on hemodialysis shows that taking curcumin 80 mg daily for 12 weeks can reduce blood glucose levels when compared with placebo (104149).
|
Turmeric has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
Details
In vitro and animal research shows that curcumin, a constituent of turmeric, inhibits doxorubicin-induced apoptosis of breast cancer cells by up to 65% (96126). However, curcumin does not seem to affect the apoptosis capacity of daunorubicin. In fact, some research shows that curcumin might augment the cytotoxic effects of antitumor antibiotics, increasing their effectiveness. Reasons for the discrepancies may relate to the dose of curcumin and the chemotherapeutic agent. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects (96125). More evidence is needed to determine what effects, if any, antioxidants such as turmeric have on antitumor antibiotics.
|
Theoretically, turmeric might increase or decrease levels of drugs metabolized by CYP1A1. However, research is conflicting.
Details
|
Theoretically, turmeric might increase levels of drugs metabolized by CYP1A2. However, research is conflicting.
Details
|
Turmeric might increase levels of drugs metabolized by CYP3A4.
Details
In vitro and animal research show that turmeric and its constituents curcumin and curcuminoids inhibit CYP3A4 (21497,21498,21499). Also, 8 case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking turmeric and cancer medications that are CYP3A4 substrates, including everolimus, ruxolitinib, ibrutinib, and palbociclib, and bortezomib (111644). In another case report, a transplant patient presented with acute nephrotoxicity and elevated tacrolimus levels after consuming turmeric powder at a dose of 15 or more spoonfuls daily for ten days prior. It was thought that turmeric increased levels of tacrolimus due to CYP3A4 inhibition (93544).
|
Theoretically, turmeric might increase blood levels of oral docetaxel.
Details
Animal research suggests that the turmeric constituent, curcumin, enhances the oral bioavailability of docetaxel (80999). However, the significance of this interaction is unclear, as this drug is typically administered intravenously in clinical settings.
|
Theoretically, large amounts of turmeric might interfere with hormone replacement therapy through competition for estrogen receptors.
Details
In vitro research shows that curcumin, a constituent of turmeric, displaces the binding of estrogen to its receptors (21486).
|
Theoretically, taking turmeric and glyburide in combination might increase the risk of hypoglycemia.
Details
Clinical research shows that taking curcumin 475 mg daily for 10 days prior to taking glyburide 5 mg increases blood levels of glyburide by 12% at 2 hours after the dose in patients with type 2 diabetes. While maximal blood concentrations of glyburide were not affected, turmeric modestly decreased postprandial glucose levels for up to 24 hours when compared to glyburide alone, possibly due to the hypoglycemic effect of turmeric demonstrated in animal research (96133).
|
Theoretically, turmeric might increase the risk of liver damage when taken with hepatotoxic drugs.
Details
|
Theoretically, turmeric might increase the effects of losartan.
Details
Research in hypertensive rats shows that taking turmeric can increase the hypotensive effects of losartan (110897).
|
Theoretically, turmeric might have additive effects when used with hepatotoxic drugs such as methotrexate.
Details
In one case report, a 39-year-old female taking methotrexate, turmeric, and linseed oil developed hepatotoxicity (111644).
|
Theoretically, turmeric might increase the effects and adverse effects of norfloxacin.
Details
Animal research shows that taking curcumin, a turmeric constituent, can increase blood levels of orally administered norfloxacin (80863).
|
Theoretically, turmeric might increase blood levels of OATP4C1 substrates.
Details
In vitro research shows that the turmeric constituent curcumin competitively inhibits OATP4C1 transport. This transporter is expressed in the kidney and facilitates the renal excretion of certain drugs (113337). Theoretically, taking turmeric might decrease renal excretion of OATP substrates.
|
Theoretically, turmeric might increase the absorption of P-glycoprotein substrates.
Details
|
Theoretically, turmeric might alter blood levels of paclitaxel, although any effect may not be clinically relevant.
Details
Clinical research in adults with breast cancer receiving intravenous paclitaxel suggests that taking turmeric may modestly alter paclitaxel pharmacokinetics. Patients received paclitaxel on day 1, followed by either no treatment or turmeric 2 grams daily from days 2-22. Pharmacokinetic modeling suggests that turmeric reduces the maximum concentration and area under the curve of paclitaxel by 12.1% and 7.7%, respectively. However, these changes are not likely to be considered clinically relevant (108876). Conversely, animal research suggests that curcumin, a constituent of turmeric, enhances the oral bioavailability of paclitaxel (22005). However, the significance of this interaction is unclear, as this drug is typically administered intravenously in clinical settings.

Turmeric might increase the effects and adverse effects of sulfasalazine.
Details
Clinical research shows that taking the turmeric constituent, curcumin, can increase blood levels of sulfasalazine by 3.2-fold (81131).
|
Turmeric might increase the effects and adverse effects of tacrolimus.
Details
In one case report, a transplant patient presented with acute nephrotoxicity and elevated tacrolimus levels of 29 ng/mL. The patient previously had tacrolimus levels within the therapeutic range at 9.7 ng/mL. Ten days prior to presenting at the emergency room the patient started consumption of turmeric powder at a dose of 15 or more spoonfuls daily. It was thought that turmeric increased levels of tacrolimus due to cytochrome P450 3A4 (CYP3A4) inhibition (93544). In vitro and animal research show that turmeric and its constituent curcumin inhibit CYP3A4 (21497,21498,21499).
|
Turmeric may reduce the absorption of talinolol in some situations.
Details
Clinical research shows that taking curcumin for 6 days decreases the bioavailability of talinolol when taken together on the seventh day (80079). The clinical significance of this effect is unclear.
|
Theoretically, turmeric might reduce the levels and clinical effects of tamoxifen.
Details
In a small clinical trial in patients with breast cancer taking tamoxifen 20-30 mg daily, adding curcumin 1200 mg plus piperine 10 mg three times daily reduces the 24-hour area under the curve of tamoxifen and the active metabolite endoxifen by 12.8% and 12.4%, respectively, as well as the maximum concentrations of tamoxifen, when compared with tamoxifen alone. However, in the absence of piperine, the area under the curve for endoxifen and the maximum concentration of tamoxifen were not significantly reduced. Effects were most pronounced in patients who were extensive cytochrome P450 (CYP) 2D6 metabolizers (107123).
|
Turmeric has antioxidant effects. There is some concern that this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
Details
In vitro research shows that curcumin, a constituent of turmeric, inhibits camptothecin-induced apoptosis of breast cancer cells by up to 71% (96126). However, other in vitro research shows that curcumin augments the cytotoxic effects of camptothecin. Reasons for the discrepancies may relate to the dose of curcumin and the chemotherapeutic agents. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects (96125). More evidence is needed to determine what effect, if any, turmeric might have.
|
Turmeric might increase the risk of bleeding with warfarin.
Details
One case of increased international normalized ratio (INR) has been reported for a patient taking warfarin who began taking turmeric. Prior to taking turmeric, the patient had stable INR measurements. Within a few weeks of starting turmeric supplementation, the patient's INR increased to 10 (100906). Additionally, curcumin, the active constituent in turmeric, has demonstrated antiplatelet effects in vitro (11143,81204,81271), which may produce additive effects when taken with warfarin.

Below is general information about the adverse effects of the known ingredients contained in the product Total Youth Antioxidant Super Food. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, alfalfa leaf seems to be well tolerated.
However, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Abdominal discomfort, diarrhea, and flatulence.
Serious Adverse Effects (Rare):
Orally: Lupus-like syndrome after chronic ingestion of alfalfa.
Dermatologic ...Dermatitis associated with alfalfa use has been reported. In a 1954 publication, dermatitis was noted in a 61-year-old female consuming 4-6 cups of tea made with two tablespoonfuls of alfalfa seeds for approximately two months prior to onset. Examination revealed diffuse, confluent edema and erythema on the face, eyelids, ears, hands, forearms, and distal humeral regions. The dermatitis improved with treatment; re-exposure to alfalfa resulted in a similar reaction (30609).
Endocrine
...Alfalfa contains constituents, including coumestrol, with reported estrogenic activity (30586,30592,4753).
Effects in humans are not known.
One case report documents hypokalemia in a female who had been drinking a "cleansing tea" containing alfalfa, licorice, and stinging nettle. The potassium level returned to normal after discontinuing the tea and initiating potassium supplementation. The specific cause of the hypokalemia is not clear. Notably, both stinging nettle and licorice have been associated with hypokalemia and may have been responsible for this effect (30562).
Gastrointestinal ...Orally, flatulence and bulkier feces were reported during the first week of a case series of three subjects ingesting alfalfa (30598). In a case series of 15 patients ingesting alfalfa, increased fecal volume and increased stool frequency was reported. Additional adverse effects included abdominal discomfort in two patients, diarrhea in two patients, loose stools in six patients, and intestinal gas in 13 patients (5816).
Hematologic ...Pancytopenia and splenomegaly were reported in a 59-year-old male who had been taking 80-160 grams of ground alfalfa seeds for up to six weeks at a time, for a five month period. Hematologic values and spleen size returned to normal when alfalfa was discontinued (381).
Other
...Alfalfa products, including sprouts, seeds, and tablets, have been found to be contaminated with Escherichia coli, Salmonella, and Listeria monocytogenes, which have caused documented infections (5600,30566,30568,30572,30569,30564,30604,30610,30563,30607) (30566,30564,30604,30610,30563,30607,30576).
Orally, alfalfa has been associated with the development of a lupus-like syndrome in animals and humans (30594,14828,14830,30602), as well as with possible exacerbations of lupus in patients with known systemic lupus erythematosus (SLE). These reactions may be associated with the amino acid L-canavanine (30594), which appears to be present in alfalfa seeds and sprouts, but not leaves, and therefore should not be present in alfalfa tablets manufactured from the leaves (30601). However, case reports have included individuals ingesting tablets. A lupus-like syndrome was described in four patients taking 12-24 alfalfa tablets per day. Symptoms included arthralgias, myalgias, and rash; positive antinuclear antibodies (ANA) arose anywhere from three weeks to seven months after initiating alfalfa therapy. Upon discontinuation of alfalfa tablets, all four patients became asymptomatic. In two patients, ANA levels normalized (14828). Two additional reports have documented possible exacerbation or induction of SLE associated with alfalfa use. One case involved a female with a 26-year history of SLE, who had been taking 15 tablets of alfalfa daily for nine months prior to an exacerbation. Because of the delay in onset of the exacerbation from the initiation of alfalfa therapy, causation cannot be clearly established (30575). In a different report, SLE and arthritis were found in multiple family members who had been taking a combination of vitamin E and alfalfa tablets for seven years (30602). It is not known what other environmental or genetic factors may have affected these individuals, and the association with alfalfa is unclear.
General
...Orally, apple fruit is well tolerated.
Apple seeds, which contain cyanide, may cause serious adverse effects when consumed in large amounts.
Most Common Adverse Effects:
Orally: Bloating, flatulence.
Serious Adverse Effects (Rare):
Orally: Allergic reactions, including anaphylaxis. Ingestion of large amounts of apple seeds may cause cyanide poisoning, leading to death.
Gastrointestinal ...Orally, apple products, including whole apples, apple puree, and apple juice, may cause bloating and flatulence in some people (104184).
Immunologic ...Patients allergic to other fruits in the Rosaceae family, including apricot, almond, plum, peach, pear, and strawberry, can also be allergic to apples (7129). Rarely, the allergy has resulted in anaphylaxis (94425).
Other ...Orally, ingestion of large amounts of apple seeds, which contain hydrogen cyanide (HCN), may cause cyanide poisoning, leading to death. One death is attributed to ingestion of a cupful of apple seeds. To release cyanide, seeds must be hydrolyzed in the stomach, and several hours may elapse before poisoning symptoms occur (6).
General ...Orally, Ascophyllum nodosum seems to be generally well-tolerated.
Endocrine ...Orally, taking Ascophyllum nodosum powder 500 mg daily for 14 days has been reported to cause elevated levels of thyroid stimulating hormone (TSH) in 2 of 22 women in a clinical trial. The powder contained 356 mcg iodine per 500 mg. Levels of free thyroxine (T4) were unaffected (94997).
Gastrointestinal ...Orally, Ascophyllum nodosum has been reported to cause stomach discomfort in one clinical trial (94996).
General
...Orally, barley is well tolerated.
Most Common Adverse Effects:
Orally: Abdominal distension, bloating, flatulence, unpleasant taste. Allergic reactions in sensitive individuals.
Topically: Allergic reactions in sensitive individuals.
Dermatologic ...Topically, barley malt contained in beer has been reported to cause contact dermatitis (33762). After occupational exposure, barley has been reported to cause contact dermatitis of the eyelids and extremities, as well as contact urticaria (33735,33770,33774).
Gastrointestinal
...When consumed orally, barley provides fiber.
Increasing fiber in the diet can cause flatulence, bloating, abdominal distention, and unpleasant taste. To minimize side effects, doses should be slowly titrated to the desired level. Adverse effects usually subside with continued use (12514).
Barley contains gluten. In patients with biopsy-proven celiac disease, consuming barley can cause gastrointestinal upset and impairment of xylose excretion (33763,33772).
Immunologic
...Orally, consumption of beer has been reported to cause allergic reactions in sensitive individuals (33722,33724).
Symptoms included tingling in the face, lip, and tongue, angioedema, generalized urticaria, chest tightness, dyspnea, cough, fainting, and rhinoconjunctivitis. It can also cause anaphylaxis in sensitive individuals (317). Topically and with occupational exposure, barley has been reported to cause contact dermatitis and rash (33762,33735,33770,33774).
"Bakers' asthma" is an allergic response resulting from the inhalation of cereal flours by workers in the baking and milling industries, and has been reported to occur after barley flour exposure (1300,33756,33760). Cross-allergenicity has been shown to exist between different cereals (33758).
Pulmonary/Respiratory
..."Bakers' asthma" is an allergic response resulting from the inhalation of cereal flours by workers in the baking and milling industries, and has been reported to occur after barley flour exposure (1300,33756,33760).
Cross-allergenicity has been shown to exist between different cereals (33758).
By inhalation, barley flours may be a source of allergens in asthma (33764,33773). Inhalation of wild barley grass pollen may result in bronchial irritation or pneumonitis (33726,33755).
General
...Orally, bilberry fruit, juice, and extracts seem to be well tolerated.
Most Common Adverse Effects:
Orally: Dark-colored stools, flatulence, and gastrointestinal discomfort.
Gastrointestinal
...In one small clinical trial, mild-to-moderate flatulence was reported in 33% of patients taking sieved bilberries and concentrated bilberry juice (91506).
However, the patients in this study had ulcerative colitis, and the study lacked a control group, limiting the validity of this finding. In another small clinical study of males with age-related cognitive impairment, temporary adverse gastrointestinal (GI) effects were reported in 13% of patients drinking a combination of bilberry and grape juice. However, the adverse GI effect rate was identical in patients drinking a placebo juice (110641). A post-marketing surveillance report of 2295 patients using bilberry extract (Tegens) found that 1% of patients complained of GI discomfort and less than 1% experienced nausea or heartburn (35500).
Theoretically, fresh bilberry fruit may have laxative effects. One clinical trial noted an increased frequency of bowel movements following the administration of a combination formulation containing aerial agrimony parts, cinnamon quills, powdered bilberry fruit, and slippery elm bark (35462). It is unclear if these effects were due to bilberry, other ingredients, or the combination.
Other ...Orally, bilberry may cause discoloration of feces and the tongue. In one study, a dark-bluish to black discoloration of both the feces and the tongue was observed following consumption of sieved bilberries and concentrated bilberry juice. In one patient, a slight discoloration of the teeth has also been observed (91506). In another study, 50% of patients reported dark green stools after taking bilberry extract 700 mg twice daily for 4 weeks (104194).
General
...Orally, spirulina blue-green algae seem to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal cramps, bloating, diarrhea, dizziness, fatigue, flatulence, headache, nausea, and vomiting.
Dermatologic ...Orally, a severe rash has been reported in a 49-year-old woman after taking a spirulina blue-green algae supplement (species and dose unknown). After stopping the supplement, inflammatory myopathy with muscle weakness and elevated creatine kinase occurred. The condition resolved with corticosteroid and cyclophosphamide treatment (75936). In another case report, an 82 year-old woman developed a blistering skin condition over a 2-year period while taking spirulina blue-green algae (A. platensis, dose unknown). She had partly hemorrhagic bullae, secreting erosions and macerations. These symptoms resolved when the supplement was stopped and the patient was treated with oral prednisone, topical silver sulfadiazine, and topical triamcinolone / neomycin (75921).
Gastrointestinal ...Orally, gastrointestinal complaints are amongst the most common adverse effects associated with spirulina blue-green algae, including nausea, vomiting, diarrhea, and abdominal cramps (19272,75924,91713,109969). Similarly, common adverse effects associated with the blue-green algae species Aphanizomenon flos-aquae are stomach upset, flatulence, diarrhea, and bloating (14842).
Hematologic ...Orally, three cases of mild gum bleeding and one case of mild bruising have been reported in patients taking spirulina blue-green algae (Cyactiv, Cerule LLC) 2. 3 grams daily (containing approximately 1 gram of phycocanin) for 2 weeks (97202).
Hepatic ...Orally, significant elevations of liver function tests within 2 weeks of starting a spirulina blue-green algae supplement (species and dose unknown) have been reported in a 52-year-old man stabilized on amlodipine, simvastatin, and acarbose. A biopsy showed feathery degeneration and ballooning of hepatic cells. Cholestasis was present, and an ex-vivo lymphocyte stimulation test for spirulina blue-green algae was positive. All drugs and the spirulina blue-green algae supplement were stopped, with return of the LFTs to normal (9172).
Immunologic
...Orally, urticarial rashes and pruritus have occurred as part of generalized allergic reactions to blue-green algae (91706,91711,91712).
In one case report, a 14-year-old male experienced anaphylaxis with urticaria, lip edema, and asthma 6 hours after taking five tablets of spirulina blue-green algae (A. platensis, strength unknown). He had a positive skin prick test. Oral challenge to an extract of the tablets, and IgE from his serum, reacted with the beta chain of C-phycocyanin from A. platensis (91712).
In another case report, a 17-year-old male with a history of multiple allergies developed rash, pruritus, angioedema, wheezing, and dyspnea within 10 minutes of taking spirulina blue-green algae (A. platensis) 300 mg. He had a positive skin test to A. platensis but no other ingredients of the tablets (91706).
Musculoskeletal ...Orally, after a 49-year-old woman stopped taking a spirulina blue-green algae supplement (species and dose unknown), the patient experienced inflammatory myopathy with muscle weakness and elevated creatine kinase. The condition resolved with corticosteroid and cyclophosphamide treatment (75936). Another case report describes acute rhabdomyolysis that occurred after consumption of spirulina (Arthrospira platensis, Hawaiian spirulina, Solgar Inc., Leonia, NJ) 3 grams daily for 1 month. The 24-year old man presented with weakness, myalgias, elevated creatine kinase and liver function tests, and myoglobinuria (75922).
General
...Orally, carrot is well tolerated when consumed as a food.
It also seems to be generally well-tolerated when consumed as a medicine. Some people are allergic to carrot; allergic symptoms include anaphylactic, cutaneous, respiratory, and gastrointestinal reactions such as hives, swelling of the larynx, asthma, or diarrhea (25820,93606,106560). In infants, excessive consumption of carrot products in nursing bottles has been reported to cause extensive caries in the primary teeth (25817).
Topically, carrot has been associated with a case of phytophotodermatitis (101716).
Dental ...Orally, feeding carrot juice to infants, with or without sugar- or acid-containing beverages, has been reported to damage teeth and cause dental caries (25817).
Dermatologic ...Orally, excessive consumption of carrots or carrot-containing products can cause yellowing of the skin, which results from increased beta-carotene levels in the blood (25817). Carrots may cause allergic reactions in some patients. Allergic responses to carrot-containing foods include skin reactions such as hives, erythema, swelling, and/or papules (25820,96306).
Gastrointestinal ...Orally, carrots may cause allergic reactions in some patients. Allergic responses to carrot-containing foods can include gastrointestinal symptoms, such as diarrhea (25820).
Immunologic
...Orally, carrots may cause allergic reactions in some patients (25820,96306,106560).
Allergic responses to carrot-containing foods can include skin reactions such as hives, erythema, swelling, and/or papules (25820,96306). For one patient, treatment of skin lesions resolved after a month of oral antihistamines and topical steroids, and avoiding further contact with carrot (96306). Allergic responses to carrot-containing foods can also include gastrointestinal symptoms, such as diarrhea, and respiratory symptoms, such as swelling of the larynx or asthma (25820). In one case, a patient with a history of allergic rhinitis and asthma who had been successfully treated with subcutaneous immunotherapy and was tolerant of consumption of raw and cooked carrots developed rhinoconjunctivitis when handling carrots. Inhalation of dust particles and aerosols produced by food processing activities and containing allergens from the peel and pulp of carrots is thought to have sensitized the airway, producing a distinct form of respiratory food allergy in which there are typically no symptoms with ingestion (106560).
Topically, a female runner developed phytophotodermatitis, which was considered possibly associated with the inclusion of carrot in a sunscreen (Yes To Carrots Daily Facial Moisturizer with SPF 15; Yes to, Inc.) (101716).
Psychiatric ...Compulsive carrot eating is a rare condition in which the patient craves carrots. According to one case report, withdrawal symptoms include nervousness, cravings, insomnia, water brash, and irritability (25821).
General
...When used orally, Fucus vesiculosus may be unsafe due to its iodine content.
Topically, Fucus vesiculosus appears to be well tolerated.
Most Common Adverse Effects:
Orally: Goiter, hyperthyroidism, hypothyroidism.
Serious Adverse Effects (Rare):
Orally: Thyroid cancer.
Cardiovascular ...In one report, a young adult with obesity developed palpitations and syncope after taking an oral weight loss supplement containing a combination of Fucus vesiculosus, dandelion, and boldo for 3 weeks. The patient was found to have a prolonged QT interval on ECG and frequent episodes of sustained polymorphic ventricular tachycardia (14321). It is not clear whether Fucus vesiculosus, another ingredient, or the combination of ingredients is responsible for this adverse effect. The product was not analyzed to determine the presence of any potential toxic contaminants.
Endocrine
...Orally, Fucus vesiculosus can cause or exacerbate hyperthyroidism due to its high iodine content (12789,13061,74217).
One case of hyperthyroidism has been reported for a 60-year-old patient taking lithium for bipolar disorder and a combination product containing Fucus vesiculosus 0.125 grams, cascara 0.170 grams, and Frangula 0.222 grams per tablet for laxative purposes. The patient had been taking one tablet of the combination laxative product daily for several years. Following discontinuation of the supplement, thyroid levels normalized (74217). Similar cases of hyperthyroidism have been reported for patients taking other seaweed-containing herbal supplements (Dream Shape; Ever Youth). Analyses of these supplements shows that these products contain triiodothyronine 1 mcg and thyroxine 3-4 mcg. In addition to seaweed, Dream Shape also contains hydrangea vine, maltose, chrysanthemum, Chinese matrimony vine, and sucrose, while Ever Youth contains radish, lotus leaf, chrysanthemum, hawthorn, senna tea, and Chinese matrimony vine (13061).
Orally, prolonged use of Fucus vesiculosus has been associated with hypothyroidism (13664). The iodine in Fucus vesiculosus can cause idiosyncratic reactions.
According to the Institute of Medicine Food and Nutrition Board, prolonged, high dietary intake of iodine is associated with goiter and an increased risk of thyroid cancer (7135).
Genitourinary ...A case of hemorrhagic cystitis characterized by dysuria and polyuria has been reported in a young adult who took a specific product (Slim-Kombu, Balestra and Mech) containing Fucus vesiculosus and 19 other herbal extracts orally for weight loss. Upon discontinuation, symptoms improved (46959). It is unclear if this effect was due to Fucus vesiculosus or other ingredients in the supplement.
Renal ...A case of hemorrhagic cystitis characterized by dysuria and polyuria has been reported in a young adult who took a specific product (Slim-Kombu, Balestra and Mech) containing Fucus vesiculosus and 19 other herbal extracts orally for weight loss. Upon discontinuation, symptoms improved (46959). It is unclear if this effect was due to Fucus vesiculosus or other ingredients in the supplement. Nephrotoxicity has been associated with oral intake of Fucus vesiculosus that was contaminated with arsenic (12800).
General
...Orally, iodine-reduced laminaria seems to be well tolerated, while other laminaria formulations may contain excess amounts of iodine, as well as arsenic.
Most Common Adverse Effects:
Intravaginally: Cervical bleeding and pelvic cramps.
Serious Adverse Effects (Rare):
Orally: Arsenic poisoning.
Intravaginally: Rupture of cervical wall, fetal hypoxia, and fetal death. Anaphylaxis in sensitive individuals.
Dermatologic ...Orally, laminaria has been linked to a report of induced or exacerbated acne (9555).
Endocrine ...Orally, laminaria can affect levels of certain thyroid hormones, and might cause hypothyroidism or hyperthyroidism, or exacerbate existing hyperthyroidism (9556,94046).
Genitourinary ...Intravaginally, laminaria used for cervical ripening can cause pelvic cramps and cervical bleeding (8945). Uterine contractions associated with laminaria use have been implicated in fetal hypoxia and subsequent intrauterine death (6). Use of endocervical laminaria tents has been associated with possible rupture of the cervical wall and subsequent neonatal and parental infection (6,8945).
Immunologic ...There are case reports of anaphylactic reactions to laminaria when used intravaginally as a cervical dilator. In at least one case, ventilation was required (102766).
Other ...Laminaria concentrates arsenic from the ocean. In one case, use of an oral laminaria supplement for several months resulted in symptoms of arsenic poisoning including headache, weakness, fatigue, worsening memory loss, rash, nail damage, diarrhea, and vomiting. Urinary arsenic levels were elevated (15588). The concentration of arsenic in laminaria may vary between different batches, and also depends upon the part of the world where it was harvested (645,10275,15588). The concentration of arsenic has been reported to be higher in preparations from Australia than from Great Britain (645,10275).
General ...Orally, quinoa seems to be well-tolerated. Rarely, quinoa can cause allergic reaction in some individuals, including anaphylaxis (99150,99151,96062).
Immunologic ...Orally, allergic reactions to quinoa have been reported (99150,96062). Anaphylaxis and pruritic reactions have occurred in at least two individuals, a 29-year-old female and a 52-year-old male. Quinoa allergy was confirmed in both patients via skin-prick testing with quinoa extract (99150,99151).
General
...Orally and topically, turmeric is generally well tolerated.
Most Common Adverse Effects:
Orally: Constipation, dyspepsia, diarrhea, distension, gastroesophageal reflux, nausea, and vomiting.
Topically: Curcumin, a constituent of turmeric, can cause contact urticaria and pruritus.
Cardiovascular ...Orally, a higher dose of turmeric in combination with other ingredients has been linked to atrioventricular heart block in one case report. It is unclear if turmeric caused this adverse event or if other ingredients or a contaminant were the cause. The patient had taken a combination supplement containing turmeric 1500-2250 mg, black soybean 600-900 mg, mulberry leaves, garlic, and arrowroot each about 300-450 mg, twice daily for one month before experiencing atrioventricular heart block. Heart rhythm normalized three days after discontinuation of the product. Re-administration of the product resulted in the same adverse effect (17720).
Dermatologic ...Following occupational and/or topical exposure, turmeric or its constituents curcumin, tetrahydrocurcumin, or turmeric oil, can cause allergic contact dermatitis (11146,79270,79470,79934,81410,81195). Topically, curcumin can also cause rash or contact urticaria (79985,97432,112117). In one case, a 60-year-old female, with no prior reactivity to regular oral consumption of turmeric products, developed urticaria after topical application of turmeric massage oil (97432). A case of pruritus has been reported following topical application of curcumin ointment to the scalp for the treatment of melanoma (11148). Yellow discoloration of the skin has been reported rarely in clinical research (113356). Orally, curcumin may cause pruritus, but this appears to be relatively uncommon (81163,97427,104148). Pitting edema may also occur following oral intake of turmeric extract, but the frequency of this adverse event is less common with turmeric than with ibuprofen (89720). A combination of curcumin plus fluoxetine may cause photosensitivity (89728).
Gastrointestinal ...Orally, turmeric can cause gastrointestinal adverse effects (107110,107112,112118), including constipation (81149,81163,96135,113355), flatulence and yellow, hard stools (81106,96135), nausea and vomiting (10453,17952,89720,89728,96127,96131,96135,97430,112117,112118), diarrhea or loose stool (10453,17952,18204,89720,96135,110223,112117,112118), dyspepsia (17952,89720,89721,96161,112118), gastritis (89728), distension and gastroesophageal reflux disease (18204,89720), abdominal fullness and pain (81036,89720,96161,97430), epigastric burning (81444), and tongue staining (89723).
Hepatic
...Orally, turmeric has been associated with liver damage, including non-infectious hepatitis, cholestasis, and hepatocellular liver injury.
There have been at least 70 reports of liver damage associated with taking turmeric supplements for at least 2 weeks and for up to 14 months. Most cases of liver damage resolved upon discontinuation of the turmeric supplement. Sometimes, turmeric was used concomitantly with other supplements and medications (99304,102346,103094,103631,103633,103634,107122,109288,110221). The Drug-Induced Liver Injury Network (DILIN) has identified 10 cases of liver injury which were considered to be either definitely, highly likely, or probably associated with turmeric; none of these cases were associated with the use of turmeric in combination with other potentially hepatotoxic supplements. Most patients (90%) presented with hepatocellular pattern of liver injury. The median age of these case reports was 56 years and 90% identified as White. In these case reports, the carrier frequency on HLAB*35:01 was 70%, which is higher than the carrier frequency found in the general population. Of the ten patients, 5 were hospitalized and 1 died from liver injury (109288).
It is not clear if concomitant use with other supplements or medications contributes to the risk for liver damage. Many case reports did not report turmeric formulation, dosing, or duration of use (99304,103094,103631,103634,109288). However, at least 10 cases involved high doses of curcumin (250-1812.5 mg daily) and the use of highly bioavailable formulations such as phytosomal curcumin and formulations containing piperine (102346,103633,107122,109288,110221).
Neurologic/CNS ...Orally, the turmeric constituent curcumin can cause vertigo, but this effect seems to be uncommon (81163).
Psychiatric ...Orally, the turmeric constituent curcumin or a combination of curcumin and fluoxetine can cause giddiness, although this event seems to be uncommon (81206,89728).
Renal ...Orally, turmeric has been linked to one report of kidney failure, although the role of turmeric in this case is unclear. A 69-year-old male developed kidney failure related to calcium oxalate deposits in the renal tubules following supplementation with turmeric 2 grams daily for 2 years as an anti-inflammatory for pelvic pain. While turmeric is a source of dietary oxalates, pre-existing health conditions and/or chronic use of antibiotics may have contributed to the course of disease (113343).
Other ...There is a single case report of death associated with intravenous use of turmeric. However, analysis of the treatment vial suggests that the vial contained only 0.023% of the amount of curcumin listed on the label. Also, the vial had been diluted in a solution of ungraded polyethylene glycol (PEG) 40 castor oil that was contaminated with 1.25% diethylene glycol. Therefore the cause of death is unknown but is unlikely to be related to the turmeric (96136).
