Our assessment
The evidence shows that for the specific product you asked about—NOW Melatonin 3 mg—data is not available from the provided sources regarding its efficacy or safety. However, the provided data does contain information on calcium. Our assessment is that calcium is a critical mineral for bone health, but supplementing with it requires careful attention to dosage and timing due to potential risks and interactions [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, ensuring your bones stay strong. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after they fire [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements in the data set. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels in the blood and urine can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].
Our recommendation
Do not start calcium supplements without first assessing your dietary intake. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. If you take any of these, take calcium at a different time of day [NIH ODS].
