How it works
Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density by depositing into bone tissue. Calcium also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories, but specific report counts for this product are not available. 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by checking your current calcium intake from food and other supplements. If you take any medications, especially thyroid medication or antibiotics, take this supplement at a different time of day. Data not available on a specific recommended dose for this product. Choose a product with a clear label and follow the manufacturer's instructions [NIH ODS].
