Our assessment
Calcium is a critical mineral for bone health, but the evidence shows you need to be cautious with supplementation. Our assessment: while calcium supports bone density and muscle relaxation [NIH ODS], the data indicates that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. This is not a supplement to take casually.
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and also plays a key role in neuromuscular relaxation, helping your muscles and nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for this product. Side effects from high calcium levels in the blood and urine include 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: get your calcium from food first. If you must supplement, do not exceed the RDA without a doctor's guidance. Always take calcium separately from the medications listed above to avoid absorption issues [NIH ODS].
