Our assessment
The evidence shows that calcium is a critical mineral for your health, but it is not risk-free. Our assessment: Calcium supports strong bones and proper nerve function, but you need to be careful with dosing to avoid serious side effects [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It works through bone mineralization to support bone density and mineral deposition. It also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports for all supplements combined. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine 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] [FDA data].
Our recommendation
Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
