Natrol Liquid Melatonin 2.5 mg Berry Natural Flavor

Brand: Natrol · Form: LIQUID, SUPPLEMENT FORM [E0165] On Market

Our assessment

The evidence shows that Natrol Liquid Melatonin 2.5 mg Berry Natural Flavor is a sleep aid, but the data provided does not contain specific information about this exact product's efficacy or safety. You should know that the active ingredient, melatonin, is not covered in the data below. The only ingredient data available is for calcium, which is not present in this product.

How it works

Based on the data provided, only calcium’s mechanism is described. Calcium supports bone mineralization and neuromuscular relaxation by aiding bone density and muscle signaling [NIH ODS]. Since this product contains melatonin, and not calcium, the mechanism of action for this specific supplement is not available from the provided data.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplements, but no specific reports are listed for this product or melatonin [FDA data]. For calcium, which is not in this product, side effects from high intake include constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. Data not available for melatonin-specific side effects.

Our recommendation

Because the provided data does not include information on melatonin, we cannot make a specific recommendation for this product. If you are considering it, consult your healthcare provider. For calcium supplements, the data shows they can reduce absorption of medications like bisphosphonates and levothyroxine, so take them at separate times [NIH ODS]. For this melatonin product, data not available to support a confident recommendation.
