How it works

Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density, and also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. You need adequate calcium for your bones to stay strong and for your muscles to function properly.

Safety profile

FDA received 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels 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].

Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available on the specific dosage of calcium or collagen in this product. Talk to your doctor before starting, especially if you take any of these medications or have a history of kidney stones or heart disease.
