Our assessment
Our assessment: For a general audience, the evidence for calcium supplements is clear but comes with important safety considerations. The data from the National Institutes of Health shows calcium supports bone density and nerve signaling [NIH ODS]. However, you should be aware that high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. The FDA has received 592059 total adverse event reports for this ingredient category, which is a significant number to consider [FDA data].
How it works
Think of calcium as a foundational mineral for your body. It works through bone mineralization, helping to support bone density and mineral deposition, and it also supports neuromuscular relaxation by aiding muscle relaxation and nerve signaling [NIH ODS].
Safety profile
The safety profile requires your attention. High levels of calcium 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available on specific side effect report counts for this product.
Our recommendation
Our recommendation: Given the potential for serious side effects and medication interactions, you should talk to your doctor before starting a calcium supplement. If you are already taking any of the listed medications, a calcium supplement may interfere with their effectiveness. The data does not provide a specific dose for this product, so work with your healthcare provider to determine if calcium supplementation is right for you [NIH ODS] [FDA data].
