Our assessment

The evidence shows that this product is formulated to deliver a specific mineral found in many supplements. Data on this exact combination is not available, so we rely on the data for the active ingredient, calcium. Our assessment: you should understand how calcium functions and its potential risks before adding this to your routine.

How it works

Think of calcium as a structural builder and a signal regulator. It supports bone density through bone mineralization and helps your muscles relax and nerves send messages properly [NIH ODS]. This makes it essential for daily function, from keeping your skeleton strong to allowing your heart to beat rhythmically.

Safety profile

FDA received 592,059 total adverse event reports across all products. For calcium specifically, safety concerns include that 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

Start by looking at your total daily calcium intake from food and other supplements. Do not exceed the Tolerable Upper Intake Level without medical supervision. Take this supplement at a different time than any medications listed above to avoid absorption issues. Data not available for exact dosing guidance on this specific product, so consult your healthcare provider to determine if this is right for you [NIH ODS].
