Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. Our assessment: you should understand that while calcium supports bone density and muscle relaxation, the data does not provide a specific recommended dosage for this product, so you must rely on the label directions [NIH ODS].
How it works
Think of calcium as a structural builder for your bones. It works through bone mineralization to support bone density and also aids neuromuscular relaxation, helping your muscles relax and nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high blood and urine levels include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS].

Start by reading the product label for the exact dose. If you take any medications listed above, separate your calcium intake by at least two hours.
