Below is general information about the safety of the known ingredients contained in the product Sleep Support. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when used orally and appropriately. 5-HTP has been used safely in doses up to 400 mg daily for up to one year (913,30007,30130). Doses up to 1.2 grams daily have been used with apparent safety for up to 10 months (914,30018,30125,30164,30165). Doses of 3 grams daily have been used safely for 3 weeks (30138). There is some controversy about the safety of 5-HTP due to concerns for eosinophilia myalgia syndrome (EMS) (902,919,7067,10084,30178). There is speculation that only certain, contaminated 5-HTP products may cause this serious adverse effect (88174). So far, there is not enough evidence to know if EMS is caused by 5-HTP, contaminants, or other unknown factors (919,7067,10084).
POSSIBLY UNSAFE ...when used orally in large doses. Doses of 6-10 grams daily have been associated with severe gastrointestinal effects and hyperkinesis (30139,30183). The risk may be reduced if the dose is increased gradually.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately.
Doses of 5-HTP up to 5 mg/kg daily have been used safely for up to 3 years in infants and children up to 12 years old (30128,30153,88173).

when used orally and appropriately, short-term.
Preliminary clinical research suggests that several multi-ingredient products containing German chamomile are safe in infants when used for up to 4 weeks (16735,19705,19715,96278). ...when used topically and appropriately, short-term. Six drops of oil infused with German chamomile flower has been applied nightly with apparent safety for up to 6 weeks in children 6-18 years old (98621).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally as a flavoring in foods. The US Food and Drug Administration (FDA) lists passion flower as a permitted food flavoring additive, to be used in the minimum quantity necessary (91203).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts, short-term. Passion flower extract has been used with apparent safety at doses up to 800 mg daily for up to 8 weeks (88198,102866). A specific passion flower extract (Pasipay, Iran Darouk Pharmaceutical Company) has been safely used at a dose of 45 drops daily for up to one month (8007,95036). Also, a tea prepared by steeping 2 grams of the dried aerial parts of passion flower in 250 mL of boiling water for 10 minutes has been used nightly for 7 nights (17374). There is insufficient reliable information available about the safety of passion flower when used topically.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term.
A specific passion flower product (Pasipay, Iran Darouk Pharmaceutical Company) has been used safely in children aged 6-13 years at a dose of 0.04 mg/ kg daily for 8 weeks (88197).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Some case reports suggest that passion flower use during the first and second trimesters of pregnancy may be associated with an increased risk for premature rupture of membranes and meconium aspiration syndrome; however, causality has not been confirmed (97279). The alkaloids harman and harmaline, which are sometimes found in passion flower, have been reported to have uterine stimulant activity (4,11020,95037). It is not known whether these constituents are present in sufficient quantities to have an effect.
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when the fruit is used in amounts commonly found in foods. ...when tart cherry fruit, fruit juice, or fruit juice concentrate is used orally in supplemental amounts for up to 3 months (17403,93149,93151,93152,93153,93154,93156,93157,93158,93160)(93161,93168,93179,105633).

Below is general information about the interactions of the known ingredients contained in the product Sleep Support. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Combining 5-HTP and carbidopa can increase the risk of serotonergic side effects.
 Details
Carbidopa is sometimes used with 5-HTP to minimize peripheral 5-HTP metabolism and boost the amount that reaches the brain. However, this combination might also increase the risk of some side effects including hypomania, restlessness, rapid speech, anxiety, insomnia, and aggressiveness (30076,30132,30158). Combining carbidopa and 5-HTP might also increase the risk of scleroderma-like skin changes due to elevated serotonin levels (1403).
|
Theoretically, concomitant use of 5-HTP with medications that cause sedation might have additive effects.
Details
|
Combining serotonergic drugs with 5-HTP might cause additive serotonergic effects.
Details
5-HTP can increase serotonin levels and cause serotonergic effects (901). Theoretically, combining serotonergic drugs with 5-HTP might increase the risk of serotonergic side effects, including serotonin syndrome and cerebral vasoconstrictive disorders (8056). However, serotonin syndrome with 5-HTP has not yet been reported in humans (104941). Monitor patients for signs of serotonin syndrome and other serotonergic side effects if using 5-HTP with serotonergic drugs.
|
Theoretically, German chamomile might have additive effects when used with CNS depressants.
Details
|
Theoretically, large amounts of German chamomile might reduce the effectiveness of oral contraceptives.
Details
In vitro, German chamomile has demonstrated antiestrogenic activity (12728). Theoretically, concomitant use of large amounts of German chamomile might interfere with contraceptive drugs through competition for estrogen receptors.
|
Theoretically, German chamomile might inhibit CYP1A2 and increase levels of drugs metabolized by these enzymes.
Details
|
Theoretically, German chamomile might inhibit CYP2C9 and increase levels of drugs metabolized by these enzymes.
Details
In vitro evidence shows that German chamomile might inhibit CYP2C9 (19720). So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP2C9 in patients taking German chamomile.
|
Theoretically, German chamomile might inhibit CYP2D6 and increase levels of drugs metabolized by these enzymes.
Details
In vitro evidence shows that German chamomile might inhibit CYP2D6 (19720). So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP2D6 in patients taking German chamomile.
|
Theoretically, German chamomile might inhibit CYP3A4 and increase levels of drugs metabolized by these enzymes.
Details
|
Theoretically, large amounts of German chamomile might reduce the effectiveness of estrogens.
Details
In vitro, German chamomile has demonstrated antiestrogenic activity (12728). Theoretically, large amounts of German chamomile might interfere with hormone replacement therapy through competition for estrogen receptors.
|
Theoretically, large amounts of German chamomile might interfere with the activity of tamoxifen.
Details
In vitro, German chamomile has demonstrated antiestrogenic activity (12728).
|
German chamomile might increase the effects of warfarin and increase the risk of bleeding.
Details
In one case, a 70-year-old female taking warfarin developed retroperitoneal hematoma and bilateral recti muscle bleeding along with an INR of 7.9 following ingestion of German chamomile tea 4-5 cups daily and use of a topical chamomile-based lotion applied 4-5 times daily (14309).
|
Concomitant use of passion flower with sedative drugs might cause additive effects and side effects.
Details
|
Theoretically, passion flower might decrease the effects of CYP3A4 substrates.
Details
In vitro research suggests that passion flower can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer (110704).
|
Theoretically, passion flower might reduce the bioavailability of OATP2B1 and OATP1A2 substrates.
Details
In vitro research shows that the passion flower constituents apigenin and vitexin inhibit OATP2B1 and OATP1A2. This inhibition may be dose-dependent. One specific high-flavonoid passion flower extract (Valverde) seems to inhibit OATP2B1 and OATP1A2, while another extract with a lower flavonoid concentration (Arkocaps) shows less potent inhibition (105095). OATPs are responsible for the uptake of drugs and other compounds into the body; however, the specific activities of OATP2B1 and OATP1A2 are not well characterized.
|
Theanine might lower blood pressure, potentiating the effects of antihypertensive drugs.
Details
|
Theoretically, theanine might have additive sedative effects when used in conjunction with CNS depressants. However, it is unclear if this concern is clinically relevant.
Details
|
Valerian can have additive sedative effects when used concomitantly with alcohol.
Details
Valerian has sedative effects (9894). Theoretically, valerian might have an additive sedative effect when combined with alcohol. Excessive sedation has been reported in an alcohol-abusing individual who took valerian and Gingko biloba (19426). However, the potential interaction between valerian and alcohol has been disputed in other research. Limited evidence suggests that a combination of valerian 160 mg and lemon balm 80 mg (Euvegal) does not cause further deterioration in reaction ability and reaction rate when taken with alcohol as compared to the effects of alcohol alone (19427).
|
Valerian can have additive sedative effects when used with alprazolam. Also, valerian in high doses might modestly increase alprazolam levels, though this is not likely to be clinically significant.
Details
Valerian has sedative effects (9894). Theoretically, valerian might cause additive sedation when combined with alprazolam. Also, a small pharmacokinetic study shows that taking valerian extract 1000 mg daily (providing 11 mg valerenic acid) might increase alprazolam levels by about 19%. This might be due to valerian's mild inhibition of cytochrome P450 3A4 (CYP3A4) (13014). Despite being statistically significant, this increase is not likely to be clinically significant.
|
Valerian can have additive sedative effects when used concomitantly with CNS depressant drugs.
Details
|
Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP2D6.
Details
Although some in vitro evidence suggests that valerian affects CYP2D6, clinical pharmacokinetic (PK) studies show that valerian is unlikely to affect the CYP2D6 enzyme (13014,13536,19430,19431). In one PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days did not affect the metabolism of dextromethorphan, a CYP2D6 substrate. In another PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of debrisoquine, an accepted CYP2D6 probe-substrate (13014,13536).
|
Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP3A4.
Details
Although some in vitro evidence suggests that valerian extract might inhibit or induce CYP3A4, clinical pharmacokinetic (PK) studies show that valerian does not have a clinically significant effect on the CYP3A4 enzyme (6450,12214,13014,13536,19431). In one PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of midazolam, an accepted CYP3A4 probe-substrate. In another PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days modestly increases levels of alprazolam, a CYP3A4 substrate, suggesting mild inhibition of CYP3A4 (13014,13536). However, this mild inhibition is unlikely to be clinically relevant.
|
Valerian might weakly inhibit glucuronidation and increase concentrations of drugs metabolized by UGT1A1 and UGT2B7.
Details
In vitro research shows that methanolic valerian extract and valerenic acid might competitively inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1) and UGT2B7 (81685).

Below is general information about the adverse effects of the known ingredients contained in the product Sleep Support. 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, 5-HTP is generally well tolerated, short-term.
Most Common Adverse Effects:
Orally: Abdominal pain, anorexia, dizziness, diarrhea, drowsiness, fatigue, headache, insomnia, nausea, and vomiting. Severity appears to be dose-dependent.
Serious Adverse Effects (Rare):
Orally: Aggression, hallucinations, mania, severe gastrointestinal complaints.
Cardiovascular ...Orally, palpitations have been reported with 5-HTP (30076,30130,30167). Conversely, bradycardia has been reported in patients taking 5-HTP 0.4-2 grams daily in combination with carbidopa 100-300 mg daily (30132). In patients with schizophrenia, a combination of 5-HTP in doses up to 6 grams daily and carbidopa 150 mg daily was associated with diaphoresis and mild diastolic hypotension, especially when doses were increased at a rate faster than 200 mg per day (30183).
Dermatologic ...Orally, 5-HTP has been reported to cause urticaria, other allergic-type skin reactions, and flushing (2204,30000,30140). A scleroderma-like illness was reported in a 70-year-old man who had been taking 5-HTP 1400 mg daily and carbidopa 150 mg daily for 20 months. Elevated serotonin levels may be linked to this condition (1403).
Gastrointestinal ...Orally, 5-HTP has been reported to cause gastrointestinal side effects such as nausea, vomiting, abdominal or epigastric pain, heartburn, constipation, diarrhea, flatulence, anorexia, and taste alteration at any dose (2203,2204,30000,30112,30114,30125,30132,30139,30140)(30165,30183,104250). Severity may be dose-dependent and also related to how quickly doses are increased (30183). Some data suggests that these effects may diminish or disappear with continued use of 5-HTP (30132).
Hematologic ...Symptoms suggestive of eosinophilia myalgia syndrome (EMS) have been reported in some patients using 5-HTP (902,10084,30178,88174,90927). In one case, a woman was exposed to 5-HTP, tetrahydrobiopterin, carbidopa, and levodopa while administering them to her children for 2 years (90927). Her diagnosis was not confirmed, and the validity of the tests performed on the 5-HTP product has been questioned (88174). Other cases of eosinophilia or EMS in patients taking 5-HTP have been attributed to impurities that resemble previously identified contaminants found in L-tryptophan products (902,919,7067,10084). The L-tryptophan contaminants associated with EMS were linked to a specific manufacturer's production method that is not used in the preparation of 5-HTP (88174). Although 5-HTP supplements have been associated with EMS, it seems that this adverse effect is likely due to the presence of contaminants in the 5-HTP products, not 5-HTP itself.
Musculoskeletal ...Orally, rhabdomyolysis was noted in one patient with progressive myoclonus epilepsy who was treated with 5-HTP 300 mg daily for 21 days (30162).
Neurologic/CNS ...Orally, 5-HTP has been reported to cause drowsiness, dizziness, insomnia, fatigue, and headache (30076,30112,30132).
Psychiatric ...Orally, 5-HTP has been associated with euphoria, hypomania and mania, anxiety, insomnia, and aggressiveness (30076,30132,30158,88179). In patients with schizophrenia, a combination of high-dose 5-HTP, up to 6 grams daily, and carbidopa 150 mg daily was associated with transient increases in hallucinations, delusions, marked confusion, looseness of associations, flight of ideas, and a hyperkinetic syndrome consisting of restlessness, hand wringing, pacing, and an inability to sit quietly in a chair (30183).
General
...Orally and topically, German chamomile is well tolerated.
Most Common Adverse Effects:
Orally and topically: Allergic reactions and irritation.
Dermatologic ...Topically, German chamomile may cause allergic dermatitis and eczema (9766,9768,10377,110318).
Gastrointestinal ...When used topically as an oral rinse, German chamomile has been reported to cause nausea and burning in the mouth in some patients (99853).
Immunologic ...Orally, German chamomile tea can cause allergic reactions including severe hypersensitivity reactions and anaphylaxis in some patients (567). In one case report, a 47-year-old female who tolerated drinking chamomile tea, reported sneezing, nasal and ocular itching, red and watery eyes, and severe rhinorrhea after 10 years of occupational exposure to German chamomile dust (90542).
Ocular/Otic ...If used near the eyes, German chamomile can cause irritation (10377).
General
...Orally, passion flower is well tolerated.
Most Common Adverse Effects:
Orally: Confusion, dizziness, hypersensitivity, and sedation.
Cardiovascular ...There is a case report involving a 34-year-old female who was hospitalized with severe nausea, vomiting, drowsiness, prolonged QT interval, and episodes of nonsustained ventricular tachycardia following use of passion flower extract tablets (Sedacalm, Bioplus Healthcare), 1500 mg on day 1 and 2000 mg on day 2 to relieve stress. All symptoms resolved within one week after passion flower was discontinued (6251).
Genitourinary ...The alkaloids harman and harmaline, which are sometimes found in small amounts in passion flower, have been reported to have uterine stimulant activity (4,11020,95037).
Hematologic ...Orally, passion flower has been reported to cause epistaxis in one clinical trial (95038). Vasculitis has also been reported with use of a specific herbal product (Relaxir) produced mainly from the fruits of passion flower (6).
Hepatic ...There is debate about whether passion flower contains cyanogenic glycosides. Several related Passiflora species do contain these constituents (3), including Passiflora edulis, which is associated with liver and pancreatic toxicity (7).
Immunologic
...An idiosyncratic hypersensitivity reaction characterized by urticaria and cutaneous vasculitis has been reported in a 77-year-old male with rheumatoid arthritis after taking a specific combination product that included passion flower extract (Naturest) (68308).
It is unclear if these effects were caused by passion flower or other ingredients.
In clinical trials, passion flower has been reported to cause allergy symptoms including sinus irritation; however, the frequency of these events was statistically nonsignificant when compared to treatment with midazolam 15 mg (95038).
Musculoskeletal ...Orally, passion flower has been reported to cause muscle relaxation in a clinical trial (95038).
Neurologic/CNS ...Orally, sedation, dizziness, ataxia, and confusion have been reported in clinical trials. However, these events generally do not necessitate discontinuation (8007,15391,15392,95036,95038). Altered consciousness has been reported with use of a specific herbal product (Relaxir) produced mainly from the fruits of passion flower (6).
General
...Tart cherry is generally well tolerated when consumed as whole fruit, juice concentrate, or seed extracts.
Most Common Adverse Effects:
Orally: Abdominal pain, asthenia, gastrointestinal upset, loose stools.
Endocrine ...One case of hyperglycemia after drinking a specific blend of tart cherry and apple juices ) has been reported (93160).
Gastrointestinal ...In a clinical study, 29% of children who consumed 75 mL of tart cherry juice concentrate twice daily for 2 weeks reported abdominal pain (112815). Two cases of loose stools after consumption of 90 whole tart cherries, and one case of gastrointestinal disturbance after drinking 10.5 ounces of tart cherry concentrate (Cherrish, Cherrish Corp.) twice daily for 14 days have been reported (93186,93192). One case of gastrointestinal symptoms after drinking a specific blend of tart cherry and apple juice (Sour cherry juice, Cherrypharm Inc.) has been reported (93160).
Immunologic ...One case of a skin reaction possibly due to cherry allergy after drinking a specific blend of tart cherry and apple juice ) has been reported (93160).
Musculoskeletal ...In a clinical study, 31% of children who consumed tart cherry juice concentrate 75 mLl twice daily for 2 weeks reported asthenia (112815).
General
...Orally, L-theanine seems to be well tolerated.
Most Common Adverse Effects:
Orally: Drowsiness, headaches.
Neurologic/CNS
...Orally, L-theanine may cause headaches (36439).
Patients have also reported drowsiness, increased duration of sleep, and increased dream activity after oral L-theanine use (96331).
A case of subtle facial tic starting within 4 days of taking L-theanine 400 mg daily has been reported for a pediatric patient. Although the tics reportedly ceased once theanine was discontinued, the child had exhibited tics in the past. Therefore, the adverse effect was not thought to be related to L-theanine (91744).
General
...Orally, valerian is generally well-tolerated.
Most Common Adverse Effects:
Orally: Dizziness, drowsiness, and mental slowness. Other reported side effects include headache, gastrointestinal upset, excitability, and vivid dreams. When used chronically and abruptly stopped, symptoms of withdrawal such as tachycardia, anxiety, irritability, and insomnia might occur. Advise patients to taper doses slowly after extended use.
Serious Adverse Effects (Rare):
Orally: Several case reports raise concerns about hepatotoxicity after the use of valerian and valerian-containing multi-ingredient dietary supplements. Withdrawal from chronic valerian use has been associated with cases of cardiac failure and hallucinations.
Cardiovascular ...When used orally in high doses for an extended period of time, valerian withdrawal has been associated with tachycardia and high output cardiac failure in one patient with a history of coronary artery disease (3487). Chest tightness has been reported for an 18-year-old female who took 40-50 capsules containing valerian 470 mg/capsule (659). A case of severe hypotension, suspected to be due to vasodilation, hypocalcemia, and hypokalemia, has been reported for a patient who injected an unknown quantity of a crude tap water extract of raw valerian root (81734).
Dermatologic ...Orally, valerian might rarely cause a rash. A case of valerian-related rash that resolved after valerian root discontinuation was reported in clinical research (19422).
Gastrointestinal ...Orally, valerian has been associated with increased incidence of gastrointestinal problems including diarrhea, nausea, vomiting, and stomach pain (15046,19406,19407,19422,110712). In one individual, taking 20 times the normal dose caused abdominal cramping (659).
Hepatic
...There have been several case reports of hepatotoxicity associated with the use of multi-ingredient oral preparations containing valerian (8243,96241).
In one case report, a 57-year-old man presented with acute hepatitis after consuming a cold and flu remedy containing valerian 2 grams for 3 days; the remedy also contained white willow, elderberry, and horseradish. Although the use of the cold and flu remedy was discontinued one month prior to symptom presentation, the acute hepatitis was attributed to valerian root and treated with steroids (96241). It is possible, however, that some of these preparations may have been adulterated with hepatotoxic agents (8243).
Hepatotoxicity involving long-term use of single-ingredient valerian preparations has also been reported (3484,17578). Also, a case of a 38-year-old female with liver insufficiency and cirrhosis of a vascular parenchymal nature who developed hepatotoxic symptoms following valerian and ethyl-alcohol abuse has been reported (81697). Symptoms resolved and laboratory values normalized following intense plasmapheresis treatment. Another case of acute hepatitis characterized by elevated aminotransferases, mild fibrosis, and liver inflammation has been reported for a 50-year-old female who consumed valerian root extract 5 mL three times weekly along with 10 tablets of viamine, a product containing dry valerian extract 125 mg/tablet, for 2 months (81696). Because a variety of doses were used in these cases, and many people have used higher doses safely, these hepatotoxic reactions might have been idiosyncratic. Tell patients the long-term effect of valerian on liver function is unknown.
Musculoskeletal ...In a case report, combined intake of valerian and passionflower caused throbbing and muscular fatigue when taken concomitantly with lorazepam (19429).
Neurologic/CNS ...Orally, valerian might cause dizziness, headaches, fatigue, sleepiness, and mental dullness (3484,17578,19411,19422,81723,89407). The severity of adverse effects appears to increase with higher doses (19411). However, taking valerian extracts in doses up to 1800 mg does not appear to significantly affect mood or psychomotor performance (10424,15044). Valerian does not usually have a negative impact on reaction time, alertness, and concentration the morning after intake (2074,8296). Clinical research shows that a single dose of valerian root 1600 mg is not associated with any changes in sleepiness, reaction time, or driving performance within 1-4 hours after intake (96240). More serious side effects may occur when valerian is taken at higher doses. In one individual, 20 times the normal dose caused tremor of the hand and foot and lightheadedness (659). In a case report, combined intake of valerian and passionflower caused shaking of the hands and dizziness when taken concomitantly with lorazepam (19429).
Psychiatric ...Orally, valerian has been associate with reports of restlessness, excitability, uneasiness, agitation, and vivid dreams (3484,17578,19411,19422). Chronic use and rapid cessation can lead to withdrawal syndrome with symptoms of agitation, insomnia, and hallucinations (104003). There appears to be a trend towards increased severity of adverse effects with higher doses (19411). A case of acute hypomania has been reported for a 21-year-old female patient who took a valerian decoction in water each night for one month to treat subclinical anxiety. Symptoms included euphoric mood, rapid speech, and increased sociability and sexual interest. Following cessation of valerian use and treatment with quetiapine 100 mg daily for two weeks, the patient recovered (89405). In another case report, an 85-year-old male with mild cognitive impairment, major depression, anxiety, and chronic kidney disease presented to the emergency department with hallucinations, confusion, and agitation thought to be due to abrupt cessation after taking valerian 600 mg daily for about 6 months. The symptoms resolved in about 5 days (104003).
