Our assessment
The evidence shows that calcium is a critical mineral for bone health, but it is not a supplement to take casually. Based on the data, you need to be aware of significant safety concerns and potential medication interactions before starting this supplement [NIH ODS].
How it works
Think of calcium as the building block for your skeleton. Its primary role is bone mineralization, helping to support bone density and mineral deposition. Additionally, calcium supports neuromuscular relaxation, which means it helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports total across all supplements in this category. For calcium specifically, the data shows that high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium 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 your calcium from food first. If you do need a supplement, be cautious: calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should take calcium supplements at a different time than these medications. Work with your healthcare provider to determine if a calcium supplement is right for you, and always monitor your total intake from food and supplements combined [NIH ODS].
