Natrol Melatonin 1 mg

Our assessment

Our assessment: Melatonin is a popular sleep aid, but the evidence for low-dose options like Natrol Melatonin 1 mg is mixed. The data provided does not include specific studies on melatonin, so we cannot confirm its effectiveness for sleep onset or jet lag from this dataset. You should be aware that the FDA has received 592,059 total adverse event reports across all supplements, but specific data for melatonin is not available in the provided materials [FDA data].

How it works

While the data does not include a mechanism for melatonin, we can note that the active ingredient in this product, calcium, has a known role in neuromuscular relaxation and supports muscle relaxation and nerve signaling [NIH ODS]. However, this is not the primary function of a melatonin supplement. Data on how melatonin itself works is not available in the provided information.

Safety profile

Safety profile: Based on the provided data, there is no specific FDA adverse event report count for Natrol Melatonin 1 mg. The total adverse event reports for all supplements is 592,059 [FDA data]. For the ingredient calcium, side effects at high levels include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Data on melatonin-specific side effects is not available in the provided materials.

Our recommendation

Our recommendation: Without specific clinical study data or FDA adverse event reports for melatonin in the provided dataset, we cannot offer a definitive recommendation for Natrol Melatonin 1 mg.

If you are taking medications such as bisphosphonates, tetracycline antibiotics, or levothyroxine, be aware that calcium can reduce their absorption [NIH ODS].
