Cooper Complete Melatonin Quick Release 3 mg

Our assessment

The evidence shows that the Cooper Complete Melatonin Quick Release 3 mg product contains 3 mg of melatonin per serving. Melatonin is a hormone that helps regulate your sleep-wake cycle. While many people use it for sleep support, we must be clear that the data provided does not include specific clinical studies or safety information for this exact product. The only ingredient-level data available is for calcium, not melatonin [NIH ODS].

How it works

For context, the data for calcium shows it supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, melatonin works differently — it signals to your brain that it is time to sleep by binding to receptors that help lower body temperature and promote drowsiness. Since no specific mechanism data for melatonin was provided in the data set, we cannot elaborate further on how this product works.

Safety profile

Data not available for melatonin side effects. The FDA has received 592,059 total adverse event reports across all supplements in the database, but no specific melatonin-related side effects or report counts were provided in the data set [FDA data]. For calcium, the data notes that high intakes might increase the risk of heart disease and prostate cancer, and can cause constipation, nausea, and abnormal heart rhythms [NIH ODS].

Our recommendation

Without specific data on melatonin safety, efficacy, or side effects for this product, we cannot provide a confident recommendation. The data set only includes information on calcium, not melatonin. We advise you to consult your healthcare provider before starting any new supplement, especially one containing 3 mg of melatonin, as individual responses vary widely. Data not available for dosage guidance.
