How it works
Calcium acts as a master regulator for your bones and muscles. It supports bone mineralization and density, and it helps your muscles relax and nerves signal properly [NIH ODS]. Think of it as the building block that keeps your skeletal structure strong and your neuromuscular system functioning smoothly.
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 of calcium 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]. Data on side effects specific to this product is not available.
Our recommendation
You should check your total calcium intake from food and other supplements before adding this product. Calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. If you take any of these, separate doses by at least two hours. Start with the lowest effective dose and discuss with your healthcare provider to avoid excessive intake [NIH ODS].
