HelloPharmacist Scorecard of CBD Natural Grapefruit Lychee Flavor by vitafusion

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

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 2 of its 2 active ingredients.
  • “Hemp extract” is listed as a grouped ingredient — the label gives one combined amount (12 mg) without saying how much of each component you get.

This product contains 2 active ingredients: melatonin and cannabidiol (CBD), along with hemp extract. Melatonin is a hormone that regulates sleep-wake cycles, while CBD is a compound derived from hemp.

The gummies also contain several inactive ingredients — glucose syrup, sugar, gelatin, water, and medium-chain triglycerides — that serve as sweeteners, binders, and carriers.

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 with melatonin and CBD.
  • We looked for evidence on: Delayed sleep phase syndrome (DSPS), Jet lag, Non-24-hour sleep wake disorder, Shift work disorder, Beta blocker-induced insomnia, Postoperative sleep disturbance — and 4 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: Melatonin is rated "Possibly Effective" for Jet lag, Beta blocker-induced insomnia.

Melatonin is likely effective for non-24-hour sleep-wake disorder and delayed sleep phase syndrome (a condition where your sleep schedule is shifted several hours later than desired). It's possibly effective for pre-procedural anxiety, sunburn, and high blood pressure, though the evidence is less strong for those uses.

We hold no effectiveness data for the CBD or hemp extract in this product.

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Melatonin is generally well tolerated for short-term use, but long-term safety is less certain — product quality also varies from brand to brand. The most common side effects are dizziness, drowsiness, headache, and nausea.

Rarely, it may increase seizure risk. There are also concerns about mood changes (including sadness, nervousness, or depression), and rare reports of hallucinations.

Long-term use has been linked to effects on growth hormone, sperm quality, and breast tissue in isolated cases. Melatonin should be avoided during pregnancy — there isn't enough reliable safety information.

Breastfeeding safety hasn't been established, so it should also be avoided unless your doctor advises otherwise.

Each ingredient & the kinds of drugs it affects

For each ingredient in CBD Natural Grapefruit Lychee Flavor with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

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

Hemp extract6 drug types · 938 drugs

Estrogens

Theoretically, hemp might interfere with hormone therapy due to its estrogenic effects.
In an ovariectomized animal model, a diet containing hemp seed 1%, 2%, or 10% resulted in normalized plasma levels of 17-beta-estradiol. The mechanism of action for this effect is unclear.

Likelihood Possible Evidence D
Ace Inhibitors (Aceis)

Theoretically, consuming hemp seed protein isolate with ACE inhibitors might have additive effects and increase the risk of hypotension.
Hemp seed protein hydrolysate has shown ACE inhibitor-like effects in a hypertensive animal model. However, hempseed oil consumption does not seem to reduce blood pressure in humans. Until more is known, monitor blood pressure and potassium levels.

Likelihood Unlikely Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, hemp seed might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
In animal research, hemp seed at 5% of the diet inhibits platelet aggregation in vitro. However, in human research, taking hemp seed oil 2 grams daily for 12 weeks does not inhibit the aggregation of platelets in vitro.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, hemp seed protein may have additive effects with antihypertensive drugs.
In a hypertensive animal model, hemp seed protein hydrolysate reduced systolic blood pressure by a mechanism possibly involving the inhibition of renin and angiotensin converting enzyme (ACE) activities. However, there was no effect of hemp seed protein on blood pressure in normotensive animals. Furthermore, hempseed oil consumption does not seem to reduce blood pressure in humans.

Likelihood Unlikely Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, hemp might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that hemp induces CYP1A2 enzymes.

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

Theoretically, hemp might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that hemp induces CYP3A4 enzymes.

Does CBD Natural Grapefruit Lychee Flavor by vitafusion interact with any medications?
Yes. Based on its ingredients, CBD Natural Grapefruit Lychee Flavor has a known interaction with 1,465 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
CBD Natural Grapefruit Lychee Flavor contains 2 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.
Can I take this while I'm pregnant or breastfeeding?
No — the safety data advises against melatonin during pregnancy, and it hasn't been studied enough in breastfeeding to know if it's safe. Talk with your doctor before using it if you're pregnant, planning to become pregnant, or nursing.
What are the most common side effects?
Dizziness, drowsiness, headache, and nausea are the most common. These are usually mild and short-lived.
Does this product actually help you sleep?
Melatonin is likely effective for non-24-hour sleep-wake disorder and delayed sleep phase syndrome specifically. It's possibly effective for general pre-procedural anxiety, but the evidence is weaker for regular insomnia.
Why can't you check the CBD and hemp extract for interactions?
We don't hold interaction data for those ingredients in our monographs, so we can't tell you how they might interact with your medications. Your pharmacist may be able to help research that.
Is melatonin safe to use long-term?
Melatonin is generally well tolerated for short-term use, but long-term safety is less certain. If you're thinking about taking it for weeks or months, that's a good conversation to have with your doctor.
