Our assessment
The evidence shows that for a general audience, calcium is a critical mineral for bone health, but the specific product you are asking about — Source Naturals Melatonin 5 mg — contains melatonin as its active ingredient, not calcium. Our assessment is based on the data provided: the supplement in question is melatonin, and we must rely on the data for calcium as the primary ingredient listed in the NIH ODS Data section. The data confirms that calcium supports bone density and neuromuscular relaxation [NIH ODS]. However, this does not apply to your melatonin product. For melatonin specifically, data on its mechanism and safety is not available in the provided information.
How it works
Think of calcium as a structural building block for your skeleton and a signal conductor for your nerves and muscles. It supports bone mineralization and helps with muscle relaxation and nerve signaling [NIH ODS]. For your melatonin product, data on how it works is not available.
Safety profile
Based on the FDA adverse event data, there are 592,059 total reports across all supplements, though this number is not specific to melatonin or calcium alone [FDA data]. For calcium, safety concerns include 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]. For your melatonin product, side effect data is not available.
Our recommendation
Our recommendation is to be cautious. Since the product is Source Naturals Melatonin 5 mg, and the only ingredient data provided is for calcium, you should not assume the safety or effectiveness of this melatonin product based on the calcium data. Data for melatonin is not available in the provided information. If you are considering a calcium supplement, the NIH ODS data indicates it can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Consult your healthcare provider before starting any new supplement. For this specific melatonin product, data is not available to make a confident recommendation.
