Our assessment
The evidence shows that while calcium is essential for bone health, the data for this specific product is limited. Our assessment is that you should approach this supplement with caution, as high intakes may pose significant health risks. Data not available for this specific product's ingredient list beyond "See label."
How it works
Think of calcium as a structural builder — it supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, 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 [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Given the potential for serious side effects at high doses and the lack of specific product data, we recommend you get your calcium levels assessed by a healthcare professional before starting any supplement. Do not exceed the established dietary guidelines without medical supervision [NIH ODS].
