What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product has 3 active ingredients. Vitamin B6 is a B vitamin used to treat deficiency and certain rare anemias; it's also studied for pregnancy-related nausea.

Melatonin is a hormone that regulates sleep-wake cycles and is used for sleep disorders and anxiety before procedures. Passiflora extract (passion flower) is a plant-based ingredient with calming and sedative properties, used for insomnia and anxiety.

The rest of the gummy is made up of inactive ingredients—glucose syrup, glucose, pectin (a gelling agent), citric acid, sodium citrate, natural passionfruit flavor, vegetable oil, and purple carrot juice concentrate—that give the product its texture, taste, and shelf life.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Sleep support and relaxation.
  • We looked for evidence on: Insomnia, Anxiety, Delayed sleep phase syndrome (DSPS), Jet lag, Non-24-hour sleep wake disorder, Sleep quality — and 2 related terms.
  • The strongest evidence on file: Melatonin is rated "Likely Effective" for Delayed sleep phase syndrome (DSPS) (Natural Medicines).
  • Also on file: Melatonin is rated "Likely Effective" for Non-24-hour sleep wake disorder.
  • Also on file: Passion Flower is rated "Possibly Effective" for Pre-procedural anxiety, Insomnia.

Vitamin B6 is effective for sideroblastic anemia and vitamin B6 deficiency, and likely effective for elevated homocysteine levels. It's possibly effective for pregnancy-related nausea and vomiting, though this use requires a doctor's guidance.

Melatonin is likely effective for non-24-hour sleep-wake disorder and delayed sleep phase syndrome (a circadian rhythm condition), and possibly effective for anxiety before procedures and high blood pressure. Passiflora extract is possibly effective for insomnia and pre-procedural anxiety, but the evidence for alcohol dependence and benzodiazepine withdrawal is not established in the data we hold.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin B6 is well tolerated at doses under 100 mg daily. Common side effects include headache, nausea, and heartburn.

High doses over time can cause nerve damage (sensory neuropathy). Melatonin is generally well tolerated short-term, with common side effects of drowsiness, headache, dizziness, and nausea; long-term safety is less certain, and product quality varies.

It may cause mood changes or, rarely, hallucinations. Passiflora extract is well tolerated and generally causes only drowsiness or dizziness, but avoid it during pregnancy due to possible effects on the uterus, and avoid it while breastfeeding because safety data are lacking.

Melatonin18 drug types · 1,461 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, melatonin may have anticoagulant effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
There are isolated case reports of minor bleeding and decreased prothrombin activity in people taking melatonin with warfarin (Coumadin). The mechanism, if any, of this interaction is unknown. Taking melatonin orally seems to decrease coagulation activity within one hour of dosing in healthy men.

Likelihood Possible Evidence B
Anticonvulsants

Theoretically, melatonin may reduce the effects of anticonvulsants. Some clinical research suggests that melatonin may increase the frequency of seizures in certain patients, particularly children with neurological impairment.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, taking melatonin with antidiabetes drugs might increase the risk of hypoglycemia.
Some clinical research shows that melatonin reduces levels of fasting blood glucose and improves glycemic control. However, other research suggests that melatonin might impair glucose utilization and increase insulin resistance, while other research has found no effect on glucose levels. Until more is known, use melatonin cautiously in combination with antidiabetes drugs.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking melatonin with antihypertensive drugs might increase the risk of hypotension or hypertension.
Some clinical research suggests that taking melatonin decreases blood pressure in healthy adults. Also, melatonin seems to lower systolic and diastolic blood pressure in individuals with high blood pressure at nighttime or untreated essential hypertension. However, melatonin seems to worsen blood pressure in patients who are taking antihypertensive medications. Immediate-release melatonin 5 mg at night in combination with nifedipine GITS (Procardia XL) increases systolic blood pressure an average of 6.5 mmHg, diastolic blood pressure by an average of 4.9 mmHg, and heart rate by 3.9 bpm. Also, results from animal research suggest that melatonin reduces the effectiveness of certain antihypertensive drugs, including methoxamine and clonidine.

Likelihood Possible Evidence A
Caffeine

Theoretically, taking caffeine with melatonin might increase levels of melatonin.
Some evidence suggests that caffeine consumption can decrease endogenous melatonin levels, while other evidence suggests that caffeine increases endogenous melatonin levels. When administered in combination with melatonin supplements, caffeine seems to increase melatonin effects and levels. The reason for this discrepancy is not completely clear. Part of the discrepancy may result from the fact that caffeine can inhibit melatonin synthesis as well as inhibit melatonin metabolism. By functioning as an adenosine receptor antagonist, caffeine may indirectly inhibit the synthesis of melatonin. Conversely, because melatonin and caffeine are both metabolized by cytochrome P450 1A2 (CYP1A2) enzyme, concomitant use of melatonin and caffeine may reduce the metabolism of melatonin, resulting in higher serum levels.

Likelihood Probable Evidence B
Cns Depressants

Theoretically, taking melatonin might increase the sedative effects of CNS depressants.
Melatonin has sedative effects. Theoretically, concomitant use of melatonin with alcohol, benzodiazepines, or other sedative drugs might cause additive sedation.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, taking contraceptive drugs with melatonin might increase the effects and adverse effects of melatonin.
Contraceptive drugs can increase the levels of endogenous melatonin. Theoretically, these drugs may increase the effects and adverse effects of oral melatonin.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, melatonin might increase levels of drugs metabolized by CYP1A2. Also, other CYP1A2 substrates might decrease the metabolism of melatonin, increasing melatonin levels.
Melatonin is metabolized in the liver primarily by the CYP2C19 and CYP1A2 enzymes. Theoretically, combined administration of melatonin with drugs metabolized by the CYP1A2 enzyme might reduce the metabolism of these drugs, resulting in increased serum levels. Conversely, some drugs metabolized by CYP1A2 may inhibit the metabolism of melatonin, resulting in increased serum levels of melatonin. Until more is known, use melatonin cautiously in patients taking drugs metabolized by these enzymes.

Likelihood Probable Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, melatonin might increase levels of drugs metabolized by CYP2C19. Also, other CYP2C19 substrates might decrease the metabolism of melatonin, increasing melatonin levels.
Melatonin is metabolized in the liver primarily by the CYP2C19 and CYP1A2 enzymes. Theoretically, combined administration of melatonin with certain drugs metabolized by the CYP2C19 enzyme may reduce the metabolism of these drugs, resulting in increased serum levels. Conversely, some drugs metabolized by CYP2C19 may inhibit the metabolism of melatonin, resulting in increased serum levels of melatonin. Until more is known, use melatonin cautiously in patients taking drugs metabolized by these enzymes.

Likelihood Probable Evidence D
Fluvoxamine (Luvox)

Theoretically, taking fluvoxamine with melatonin might increase levels of melatonin.
Fluvoxamine can significantly increase melatonin levels. In some cases, fluvoxamine might increase bioavailability of exogenously administered melatonin by up to 20 times. Some researchers think this might be a beneficial interaction and be potentially useful for cases of refractory insomnia. However, this interaction might also cause unwanted excessive drowsiness and possibly other adverse effects. Fluvoxamine is known to increase endogenous melatonin secretion. It seems to increase serum levels of exogenously administered melatonin possibly by decreasing melatonin metabolism by inhibiting cytochrome P450 (CYP450) 1A2 and 2C19 or by inhibiting melatonin elimination. This effect has been found in healthy people taking fluvoxamine 50-75 mg and melatonin 5 mg.

Likelihood Probable Evidence B
Immunosuppressants

Theoretically, melatonin might interfere with immunosuppressive therapy.
Melatonin can stimulate immune function. Theoretically, melatonin might interfere with immunosuppressive therapy.

Likelihood Possible Evidence B
Methamphetamine (Desoxyn)

Theoretically, taking melatonin with methamphetamine may increase the adverse effects of methamphetamine.
Animal research suggests that melatonin exacerbates the adverse effects of methamphetamine, resulting in greater depression of tryptophan hydroxylase (TPH) and tyrosine hydroxylase (TH) activity, as well as a significant reduction in dopamine levels. This has not been shown in humans.

Likelihood Possible Evidence D
Nifedipine Gits (Procardia Xl)

Theoretically, taking melatonin with extended release nifedipine reduces the effects of nifedipine.
Melatonin can decrease the effectiveness of extended release nifedipine (GITS). Immediate-release melatonin 5 mg at night in combination with nifedipine GITS 30-60 mg daily increases systolic and blood pressure by an average of 6.5 mmHg and 4.9 mmHg, respectively. Concomitant use with melatonin also increases heart rate by 3.9 bpm. The mechanism of this interaction is not known.

Likelihood Probable Evidence B
Seizure Threshold Lowering Drugs

Theoretically, taking melatonin with drugs that lower the seizure threshold might increase the risk of seizure activity.
Some clinical evidence suggests that melatonin may increase the frequency of seizures in certain patients, particularly children with neurological disabilities.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, melatonin may have antiplatelet effects and may increase the risk of bleeding with warfarin.
Three cases of increased prothrombin time have been reported for patients aged 48-72 years who took melatonin orally in combination with warfarin. However, three cases of decreased prothrombin time have also been reported for patients aged 51-84 years who took melatonin orally in combination with warfarin. Until more is known, use melatonin cautiously in patients taking warfarin.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, melatonin might increase levels of drugs metabolized by CYP2D6.
Laboratory research suggests that certain lots of melatonin inhibit CYP2D6. Theoretically, combined administration of melatonin with certain drugs metabolized by the CYP2D6 enzyme may reduce the metabolism of these drugs, resulting in increased serum levels. Until more is known, use melatonin cautiously in patients taking drugs metabolized by these enzymes.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, melatonin might increase levels of drugs metabolized by CYP3A4.
Laboratory research shows that certain lots of melatonin inhibit CYP3A4. Theoretically, combined administration of melatonin with certain drugs metabolized by CYP3A4 may reduce the metabolism of these drugs, resulting in increased serum levels. Until more is known, use melatonin cautiously in patients taking drugs metabolized by these enzymes.

Likelihood Possible Evidence D
Flumazenil (Romazicon)

Theoretically, taking flumazenil with melatonin might reduce the effects of melatonin.
Animal research shows that flumazenil may inhibit the effect of melatonin.

Likelihood Possible Evidence D
Melatonin full monograph & interactions

Passiflora extract3 drug types · 836 drugs

Cns Depressants

Concomitant use of passion flower with sedative drugs might cause additive effects and side effects.
Research in animals and humans shows that passion flower has sedative effects which can be additive when used with sedative medications like lorazepam.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, passion flower might decrease the effects of CYP3A4 substrates.
In vitro research suggests that passion flower can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer.

Likelihood Possible Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Theoretically, passion flower might reduce the bioavailability of OATP2B1 and OATP1A2 substrates.
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. 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.

Likelihood Possible Evidence D
Passiflora extract full monograph & interactions

Vitamin B65 drug types · 210 drugs

Amiodarone (Cordarone)

Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.

Likelihood Possible Evidence B
Phenobarbital (Luminal)

High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Levodopa

Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.

Hibernate Gummy Edition Natural Passionfruit Flavor by High Level: Common Questions

Does Hibernate Gummy Edition Natural Passionfruit Flavor by High Level interact with any medications?
Yes. Based on its ingredients, Hibernate Gummy Edition Natural Passionfruit Flavor has a known interaction with 1,472 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Hibernate Gummy Edition Natural Passionfruit Flavor contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will this keep me drowsy the next day?
Drowsiness is a common side effect of melatonin and passiflora, especially if you're sensitive to them. Start with one gummy and see how you feel the next morning. If grogginess is an issue, try taking it earlier in the evening or talk to your pharmacist about timing or dose.
Is this safe to take every night?
Melatonin is well tolerated for short-term use, but long-term safety isn't as clear. Passiflora is generally well tolerated short-term too. If you're thinking about nightly use for weeks or months, check with your doctor first to make sure it's right for you.
Can I take this if I'm pregnant?
Passiflora extract should be avoided in pregnancy due to lack of safety data and possible effects on the uterus. Melatonin and vitamin B6 have no pregnancy or breastfeeding information on file for this product, so there isn't enough data to know either way. Talk with your doctor or pharmacist before taking it during pregnancy or while breastfeeding.
What's vitamin B6 doing in a sleep gummy?
Vitamin B6 is included in small amounts here. At recommended levels, it's generally well tolerated and is used to support overall health. The interactions with seizure and blood pressure medications mainly happen at high doses, but it's still worth checking with your pharmacist if you take those drugs.
Will this work if I've used melatonin supplements before without effect?
Melatonin works best for circadian rhythm disorders like delayed sleep phase syndrome and non-24-hour sleep-wake disorder. If you've tried melatonin alone without success for general insomnia, adding passiflora might help, but results vary. A pharmacist can suggest other approaches if this doesn't work for you.
What if I'm allergic to plants—is this safe?
Passiflora is a plant extract, so if you have a history of plant allergies or sensitivities, mention it to your pharmacist before trying this product. Rare cases of allergic reactions and skin reactions have been reported with passiflora. If you develop hives, rash, or other allergy signs, stop and seek help.
