Our assessment
The evidence shows that the primary mineral in this supplement, calcium, is essential for bone health. Our assessment is that this product can be a useful option if you are looking to support your bone density, as calcium is a key component of bone mineralization [NIH ODS]. However, you should be aware of the specific risks and interactions associated with calcium supplementation.
How it works
Think of calcium as a structural building block for your bones and a communication messenger for your body. It directly supports bone density and mineral deposition, which is how your skeleton maintains its strength [NIH ODS]. Additionally, calcium plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, though specific report counts for this product are not available. Regarding calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very 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].
Our recommendation
If you choose to take this supplement, be mindful of interactions. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should take calcium at a different time of day than these medications. We recommend discussing your total calcium intake from both food and supplements with your doctor to avoid exceeding safe levels [NIH ODS].
