Our assessment
Our assessment: This product provides calcium, a mineral essential for bone health. The data shows calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, we must be very clear about the risks. High calcium intakes may increase the risk of heart disease and prostate cancer, and extremely high levels can cause serious health issues including poor muscle tone, kidney problems, and abnormal heart rhythms [NIH ODS].
How it works
Think of calcium as a structural building block for your bones. It works by supporting bone density and mineral deposition, and it also helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, though the number specific to this product is not available. For calcium specifically, side effects from high levels include constipation, nausea, weight loss, extreme tiredness, and frequent need to urinate [FDA data] [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Use this supplement only if you have a confirmed calcium deficiency or your healthcare provider advises it. Do not exceed the RDA without medical supervision. If you take any of the medications listed above, take calcium at a different time of day to avoid interactions [NIH ODS]. Data on this specific formulation's safety profile is not available beyond the general calcium warnings.
