Our assessment
The evidence shows that calcium is a critical mineral for your bone health and nerve function, but it comes with important safety considerations. Our assessment: you should approach calcium supplementation with caution and ideally obtain it from food sources first [NIH ODS].
How it works
Calcium acts as a structural building block for your bones and teeth, and it plays a key role in neuromuscular relaxation — helping your muscles relax and your nerves send signals properly [NIH ODS]. Think of it as the raw material that keeps your skeleton strong and your muscles working smoothly.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Symptoms of excessive calcium include constipation, nausea, extreme tiredness, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Prioritize getting calcium from food before turning to supplements. If you do supplement, do not exceed the recommended daily intake without medical supervision, and take calcium separately from your other medications to avoid absorption issues [NIH ODS].
