Our assessment
The evidence shows that calcium is a critical mineral for bone health, but supplementing with it requires careful attention to dosage. Our assessment is that you should prioritize getting calcium from food sources first and only use supplements to fill a verified gap in your diet [NIH ODS].
How it works
Think of calcium as a structural builder and a signal messenger for your body. It supports bone density and mineral deposition — essentially building and maintaining your skeleton — and it also enables muscle relaxation and proper nerve signaling [NIH ODS].
Safety profile
Data not available for this specific product. However, for calcium in general, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. 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]. FDA received 592,059 total adverse event reports across all supplements, but a specific count for this product is not available [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Do not start calcium supplements without first assessing your dietary intake. If you decide to supplement, take it with food and in divided doses of no more than 500 mg at a time for better absorption. Be aware of the significant interactions with medications — separate your calcium dose from any thyroid medication or antibiotics by at least 2 hours [NIH ODS].
