Our assessment
The evidence shows that calcium is a well-established mineral for bone health, but the data on high-dose supplementation, such as the 5 mg melatonin product you asked about, does not apply here. For calcium specifically, our assessment is that it is essential for bone mineralization and neuromuscular relaxation [NIH ODS]. However, data on the specific product "Natural Factors Stress-Relax Melatonin 5 mg" is not available for an assessment of its active ingredient.
How it works
Think of calcium as a key structural component. It supports bone density and mineral deposition, acting as a master regulator for your skeleton. It also plays a role in neuromuscular relaxation, helping your muscles relax and nerves signal properly [NIH ODS].
Safety profile
Data not available for this specific product. However, for calcium supplements generally, FDA received a total of 592,059 adverse event reports across all supplements. High calcium intakes may increase the risk of heart disease and prostate cancer. High levels 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].
Our recommendation
Data not available for this product. For calcium, we recommend getting your intake from food sources first. If you need a supplement, consult your doctor about the right dose for you, as calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
