Our assessment
The evidence shows that this supplement provides calcium, a mineral essential for bone health.

Our assessment is that you can meet your calcium needs with more common and less expensive supplements [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a key signal for your nerves and muscles. It supports bone mineralization and density, and it is also necessary for muscle relaxation and nerve signaling [NIH ODS].
Safety profile
Safety data is based on the ingredient calcium. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium 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]. The FDA has received a total of 592,059 adverse event reports for supplements in this category, though this number is not specific to this product alone [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your dietary calcium intake from food sources like dairy, leafy greens, and fortified foods. If you need a supplement, a standard calcium carbonate or calcium citrate product is a well-studied and reliable choice [NIH ODS]. Data not available for a specific recommendation on this brand.
