How it works

For the ingredient calcium, the mechanism involves bone mineralization by supporting bone density and mineral deposition, as well as neuromuscular relaxation through support of muscle relaxation and nerve signaling [NIH ODS].

Safety profile

Based on FDA adverse event data, there are a total of 592,059 reports across all supplements, but no specific side effect counts are provided for Natrol Melatonin 3 mg or for calcium alone in the FDA data.

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]. No side effect reports with counts are available for Natrol Melatonin 3 mg from the provided FDA data.
