Our assessment
The evidence shows that this product contains melatonin, but the data provided does not include specific clinical studies or dosage guidelines for this ingredient. Our assessment is based on the available data for the other ingredient listed: calcium. For calcium, the evidence supports its role in bone health, but you must be aware of the safety risks and potential interactions with medications [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density, and it also helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports across all products. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels 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] [FDA data].
Our recommendation
Before taking this supplement, check your current calcium intake from food and other supplements. Be aware that calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For melatonin-specific guidance, data is not available in the provided information. Consult your healthcare provider to determine if this product is right for you.
