Nutrabear Melatonin 5,000 mcg Strawberry Flavored Gummies

Our assessment

The evidence shows that this product contains 5,000 mcg (5 mg) of melatonin per serving, which is a high dose. For context, typical doses range from 0.5 mg to 5 mg. Our assessment: you should be cautious with this high dose, as the data on long-term safety at this level is not fully established. Data not available for specific benefits at this dosage.

How it works

Melatonin is a hormone your body naturally produces to regulate your sleep-wake cycle. Think of it as a sleep signal — it tells your brain that it's time to rest. While calcium supports bone mineralization and neuromuscular relaxation [NIH ODS], melatonin primarily works by binding to receptors in your brain to promote drowsiness. Data not available on the specific mechanism for a 5,000 mcg gummy formulation.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all dietary supplements in their database. Data not available on the number of reports specifically for this product or for melatonin at this dosage. Side effects for high-dose melatonin can include drowsiness, headache, dizziness, and nausea, though specific report counts for these are not provided in the data. For calcium, high intakes may cause constipation, nausea, and abnormal heart rhythms [NIH ODS].

Our recommendation

Our recommendation: start with a much lower dose of melatonin, typically 0.5 mg to 3 mg, taken 30-60 minutes before bed. The 5,000 mcg dose in this product is very high and may cause next-day drowsiness. You should consult your healthcare provider before using this supplement, especially if you take any medications, as calcium can interfere with the absorption of antibiotics and thyroid medication [NIH ODS].
