Our assessment
The evidence shows that the active ingredient in this supplement, Calcium, is well-studied for bone health. However, be cautious with dosage, as high intakes carry significant risks. Data not available for specific product formulation benefits beyond the ingredient itself.
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it 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. Side effects of high calcium levels 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]. Calcium can also reduce the absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you need a calcium supplement, start with a low dose and take it with food. Be aware of the serious risks at high intakes and the medication interactions listed above. Monitor your total calcium intake from all sources [NIH ODS].
