Our assessment
The evidence shows that calcium is a critical mineral for bone health, but the safety profile requires careful attention. Our assessment: this supplement can be beneficial if you need to fill a dietary gap, but you must be cautious about total daily intake from all sources [NIH ODS].
How it works
Think of calcium as the structural foundation for your skeleton. It supports bone density and mineral deposition, and also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. 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]. Also, calcium can 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 recommended dose for this product. Before taking this supplement, review your total calcium intake from food and other supplements. If you take prescription medications, especially antibiotics or thyroid medication, separate your calcium dose by at least 2 hours [NIH ODS].
