How it works
Based on the data for Calcium, which is listed as a category mineral for this product, it supports bone mineralization by helping with bone density and mineral deposition. It also plays a role in neuromuscular relaxation, supporting muscle relaxation and nerve signaling [NIH ODS].
Safety profile
Data not available for Iron specifically. The FDA adverse event database contains a total of 592,059 reports across all supplements, but report counts specific to this product are not listed. For the ingredient Calcium, high intakes might increase the risk of heart disease and prostate cancer. High levels 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
Because the data provided does not include information on the active ingredient Iron, we cannot make a recommendation for this specific product. For supplement safety, calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
