Natrol Melatonin 1 mg Fast Dissolve Strawberry

Our assessment

The evidence shows that this product, Natrol Melatonin 1 mg Fast Dissolve Strawberry, contains a single active ingredient. Our assessment is based on the data provided for the ingredient calcium, which is listed in the NIH ODS data. There is no specific data provided for melatonin itself. For the ingredient calcium, the data supports its role in bone mineralization and neuromuscular relaxation, but also notes significant safety concerns at high intakes [NIH ODS].

How it works

Think of calcium as a key structural component for your bones and a critical messenger for your nerves and muscles. It supports bone density and mineral deposition, and it helps regulate muscle relaxation and nerve signaling [NIH ODS]. However, you should know that this product's label lists melatonin, not calcium, and no mechanism of action data was provided for melatonin.

Safety profile

Data for this specific product's ingredient (calcium) shows that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. The FDA received a total of 592,059 adverse event reports for all products, but report counts specific to this product or melatonin are not available [FDA data].

Our recommendation

Based on the data provided, we cannot make a confident recommendation for this specific product because the ingredient data (calcium) does not match the product label (melatonin). Data for melatonin is not available. If you are considering a melatonin supplement, we advise you to consult with your healthcare provider, as the safety profile and appropriate dosing for melatonin are not covered by the data provided here.
