Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. For a general audience, it is important to understand that while calcium supports bone density and muscle relaxation, the data also highlights significant safety considerations that you must be aware of before supplementing [NIH ODS].
How it works
Think of calcium as a building block for your skeleton. Its primary role is bone mineralization, which supports bone density and mineral deposition. It also plays a key part in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after activity [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports for this product. Regarding the calcium ingredient, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. 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 [FDA data] [NIH ODS].
Our recommendation
Because calcium can reduce the absorption of several medications — including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin — you should take this supplement at least two hours apart from those medicines. Data on optimal dosing for this specific product is not available, so consult your healthcare provider before starting [NIH ODS].
