DC Melatonin 5 mg

Our assessment

The evidence shows that while calcium is essential for bone health, this specific product — DC Melatonin 5 mg — contains only melatonin, not calcium. Data on calcium as a separate ingredient indicates it supports bone density and muscle relaxation [NIH ODS]. However, our assessment of this product is limited because the label lists melatonin as the sole ingredient. We must be clear: the data provided does not include specific studies or adverse event reports for this exact product, so we rely on general ingredient information.

How it works

Think of calcium as a structural building block for your skeleton and a signaling molecule for your nerves and muscles. It supports bone mineralization and neuromuscular relaxation [NIH ODS]. For this product, the active ingredient is melatonin, which is not covered in the provided data. No mechanism of action is available for melatonin from the data given.

Safety profile

Data not available for this specific product. For the ingredient calcium, there were 592059 total adverse event reports across all products in the FDA database [FDA data]. Potential side effects from high calcium intake include constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. No side effect report counts are provided for this specific product.

Our recommendation

Our recommendation is to consult your healthcare provider before starting this supplement. Since the label shows melatonin 5 mg and the data provided focuses on calcium, we cannot offer a confident recommendation for this product based on the available information. The data does not confirm the product's intended use or its safety profile. For bone health, if you are considering calcium, the data suggests being mindful of high intake levels and potential interactions with medications [NIH ODS].
