Our assessment
Our assessment: The evidence shows that calcium is a foundational mineral for your health, but it requires careful management. You need to be precise with your dosage and aware of potential risks, as the data reveals significant safety concerns at high intakes [NIH ODS].
How it works
Think of calcium as the structural backbone for your bones and a critical signal regulator for your nerves and muscles. It supports bone density and mineral deposition, and it helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
Data not available for this specific product label. However, the FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Symptoms of excessively high calcium levels in your blood and urine include 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 assessing your dietary calcium intake from food before adding a supplement. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Our recommendation is to consult your doctor to determine if a supplement is necessary and to ensure you avoid the risks associated with high calcium intake [NIH ODS].
