Our assessment
The evidence shows that calcium is a critical mineral for bone health, but the data also reveals important safety considerations you need to know. Our assessment is that while calcium supports bone density and muscle function, you should approach supplementation with caution due to potential risks [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, and it also supports neuromuscular relaxation by aiding muscle relaxation and nerve signaling [NIH ODS].
Safety profile
The FDA has received 592,059 total adverse event reports across its supplement database. 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Given the potential risks, our recommendation is to prioritize getting calcium from food sources first. If you do use a supplement, take it with meals and separate it from medications that interact.
