Our assessment
The evidence shows that calcium is a critical mineral for bone health, but supplementation requires careful consideration. While calcium supports bone density and neuromuscular function, the data indicates that high intakes may pose risks. You should only supplement if your dietary intake is insufficient, and you should not exceed the recommended dietary allowance without medical guidance [NIH ODS].
How it works
Think of calcium as a building block for your skeleton and a signal regulator for your nerves and muscles. It supports bone mineralization, which helps maintain bone density, and it promotes neuromuscular relaxation by aiding 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
Start by assessing your dietary calcium intake from food sources. If you do supplement, avoid high doses. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Take calcium supplements at a different time than these medications [NIH ODS].
