How it works
Calcium acts as a master regulator for your body. It supports bone mineralization to maintain bone density and 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 supplements, though specific reports for this product are not isolated here. 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you are taking this product for fiber, data on its fiber content is not available. For the calcium component, do not exceed recommended intakes without consulting your doctor. You should take this supplement at a different time than any prescription medications listed above to avoid absorption issues. Start with the lowest effective dose and monitor for side effects like constipation or nausea [NIH ODS].
