How it works

Calcium functions as a master regulator for your body’s structural and signaling systems. It supports bone mineralization and density, and it helps your muscles relax and nerves communicate properly [NIH ODS]. Think of it as the raw material your body uses to keep your skeleton strong and your neuromuscular system operating smoothly.

Safety profile

FDA received 592,059 total adverse event reports across all supplements, but specific report counts for this product are not available. Regarding calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects of excessive calcium include constipation, nausea, weight loss, extreme tiredness, frequent urination, 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

Start by reviewing the product label for exact calcium content. Without specific dosage information, we cannot recommend a starting dose. Have your healthcare provider check your calcium levels and kidney function before taking this supplement. If you take any of the medications listed above, take calcium at least two hours apart from them [NIH ODS]. For personalized guidance, consult your pharmacist or doctor.
