Our assessment
The evidence shows that calcium is a critical mineral for your bone health, but it comes with important safety considerations. Our assessment is that you should be cautious about high intake levels, as the data links excessive calcium to potential risks for heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, and it also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for a specific daily dose for this product. We recommend you focus on getting calcium from food sources first and consult your healthcare provider before starting a supplement, especially if you take any of the listed medications [NIH ODS].
