Our assessment
The evidence shows that the value of calcium supplements is highly dependent on your individual dietary intake and health status. For most adults, getting calcium from food is preferable, and supplementation should be approached cautiously because high intakes carry specific risks [NIH ODS].
How it works
Think of calcium as a structural powerhouse — it is essential for bone mineralization and density, and it supports muscle relaxation and nerve signaling throughout your body [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplement categories. For calcium specifically, high intakes 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 [FDA data] [NIH ODS]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
Do not exceed the Tolerable Upper Intake Level unless directed by your physician. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin — take these at separate times [NIH ODS].
