Our assessment
The evidence shows that NOW High Potency Melatonin 5 mg is a supplement used to support sleep. However, based on the data provided, the active ingredient in this product is not calcium, and no specific data on melatonin was included in the provided information. Therefore, our assessment for this specific product is limited. For calcium, which is not the ingredient in this product, the data shows it supports bone mineralization and nerve signaling [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a key player in nerve and muscle function. It supports bone density and mineral deposition, as well as muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for melatonin are not available in the provided data. For calcium, which is not the ingredient in this product, the safety data indicates that high 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] [FDA data].
