How it works
Calcium functions as a master regulator for your body. It supports bone mineralization and density, and it plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. This means calcium is critical for keeping your bones strong and your muscles and nerves working properly.
Safety profile
The FDA has received a total of 592,059 adverse event reports related to supplements, though specific side effect counts for this product are not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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].
Our recommendation
Our recommendation is to be cautious with calcium supplements. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should take this supplement at least two hours apart from any of these medications. Consult your doctor before starting this product, especially if you have a history of kidney problems or heart disease. Data on a specific recommended dosage is not available.
