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 plays a role in helping your muscles relax and nerves signal properly [NIH ODS].
Safety profile
FDA received 592059 total adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High blood and urine levels 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]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Based on the data, if you are taking this supplement for its calcium content, be cautious about total intake from all sources to avoid high levels [NIH ODS]. You should also take this supplement at a different time than any of the listed medications to prevent absorption issues [NIH ODS]. Data for the specific benefits or risks of the methylcobalamin component is not available in this analysis.
