Our assessment
Our assessment: This product contains a significant amount of calcium, and the evidence shows you should be cautious about taking it without understanding your current intake. Calcium is critical for bone health, but taking too much, especially from supplements, carries real risks [NIH ODS].
How it works
Calcium is a mineral that works as a structural building block for your bones and teeth, a process called bone mineralization. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly after they fire [NIH ODS]. Think of it as the "off switch" for muscle contraction.
Safety profile
Data not available for this specific product. However, for the general category of calcium supplements, the FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, some research suggests that high 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Do not take this supplement unless you have a clear reason, such as a known deficiency confirmed by a healthcare provider. Most people get enough calcium from food. If you take it, separate your dose by at least two hours from any prescription medications listed above. Given the potential for serious side effects from excess intake, consider getting your calcium primarily from dietary sources [NIH ODS].
