Our assessment
The evidence shows that your product, Natural Factors Stress-Relax Melatonin 5 mg, contains melatonin as its active ingredient. However, the data provided only includes information on calcium. Based on the available data, we cannot assess the effectiveness or safety of melatonin specifically. For calcium, our assessment is that it is a well-researched mineral essential for bone health and nerve function [NIH ODS].
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization to maintain strong bones and density, and it aids neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS].
Safety profile
Data not available for melatonin. For calcium, FDA received 592,059 total adverse event reports across all supplements. Side effects from high calcium intake include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [FDA data]. High levels can also lead to poor muscle tone, poor kidney function, and a high risk of death from heart disease [NIH ODS].
Our recommendation
Because the data provided covers calcium, not melatonin, we cannot offer a specific recommendation for your product. If you are considering calcium, talk to your doctor about your needs, as high doses carry serious risks. Remember that calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. For melatonin guidance, data is not available in this review.
