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

You should be aware of the clear benefits and significant safety considerations before taking this supplement.
How it works
Think of calcium as the building block for your bones. It supports bone density and mineral deposition through a process called bone mineralization [NIH ODS]. Calcium also acts as a messenger for your nerves and muscles, supporting neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories, though this number is not specific to calcium alone [FDA data]. The data shows that high levels of calcium in your blood and urine can cause serious issues including constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
You should be cautious with calcium supplements. They can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available on the specific dose or form of calcium in this product. We recommend you get your calcium levels tested by a doctor and discuss whether supplementation is necessary before starting this product.
