Our assessment
The evidence shows that this product contains melatonin, but the data provided does not support a specific assessment for its use. Data not available on melatonin's mechanism or efficacy from the provided sources. For calcium, a separate ingredient listed in the data, our assessment is that it is a critical mineral for bone health, but you must be cautious with intake levels [NIH ODS].
How it works
Think of calcium as a structural foundation — it supports bone mineralization and density, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
Data not available for melatonin from the provided FDA data. For calcium, the FDA received a total of 592,059 adverse event reports across all supplements. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high calcium 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].
Our recommendation
Because the provided data does not include specific information on melatonin, we cannot make a recommendation for this product. For calcium, you should be aware that it can reduce the absorption of medications like bisphosphonates, certain antibiotics, and levothyroxine [NIH ODS]. Consult your healthcare provider before starting any new supplement, especially if you take prescription medications.
