Our assessment
The evidence shows that calcium is a critical mineral for bone health and nerve function, but you must be careful with dosing. Our assessment is that while calcium is essential, high intakes may carry significant risks that you need to understand before supplementing [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton and a signal conductor for your nerves. It supports bone density through bone mineralization and helps your muscles relax by aiding neuromuscular signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements, though specific data for calcium alone is not available. You should know that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels in your 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
Start by getting calcium from food sources first. If you need a supplement, do not exceed the recommended daily allowance without medical supervision. Calcium can reduce absorption of bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin — take these medications at least two hours apart from calcium [NIH ODS].
