Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. However, you should be aware of important safety considerations and potential interactions before use [NIH ODS].
How it works
Calcium supports bone mineralization by helping maintain bone density and mineral deposition. It also plays a role in neuromuscular relaxation, aiding muscle relaxation and nerve signaling throughout your body [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Excess 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 data].
Our recommendation
Before using this supplement, check your current calcium intake from food and other supplements. Calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. You should take these medications at least two hours apart from calcium [NIH ODS]. Data not available for specific dosing recommendations for this product.
