Our assessment
The evidence shows that calcium is a critical mineral for bone health, but it requires careful dosing. Our assessment: a calcium supplement should only be taken if you cannot meet your needs through food, as high intakes carry real risks [NIH ODS].
How it works
Think of calcium as the structural foundation for your bones and teeth. It supports bone mineralization and density, and it also plays a role in muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high levels 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. Some research also suggests high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS] [FDA data].
Our recommendation
Prioritize getting calcium from food first. If you must supplement, take it with food and separate it from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin by at least 2 hours [NIH ODS].
