Our assessment
The evidence shows that calcium is a critical mineral for bone health, but it must be taken with caution. For most adults, the goal is to meet the RDA through diet first, as high-dose supplements carry real risks [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone density and mineral deposition, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. 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 [NIH ODS] [FDA data].
Our recommendation
Start by assessing your dietary calcium intake from food sources. If you need a supplement, choose one with no more than 500 mg per dose to improve absorption. Take calcium separately from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, as it can reduce their absorption [NIH ODS].
