Our assessment
The evidence shows that calcium is a critical mineral for bone health, but it requires careful dosing. Our assessment is that you should prioritize getting calcium from food sources before considering supplements, as high intake from supplements carries notable risks [NIH ODS].
How it works
Think of calcium as the structural building block for your skeleton. It supports bone mineralization and density, and also plays a key role in muscle relaxation and nerve signaling [NIH ODS]. Your body tightly regulates calcium levels, so taking too much can overwhelm this system.
Safety profile
The FDA has received 592,059 total adverse event reports across supplement categories, though specific numbers for calcium alone are not available. Data not available for calcium-specific report counts. Side effects from high calcium intake can include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease. High calcium intakes might also increase the risk of heart disease and prostate cancer [NIH ODS] [FDA data].
Our recommendation
Start by meeting your calcium needs through dietary sources. If you need a supplement, choose one that provides no more than 500-600 mg per dose. Take calcium supplements separately from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, as calcium can reduce their absorption [NIH ODS].
