GNC Ultra Iron 65
Brand: GNC · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that the primary ingredient in GNC Ultra Iron 65 is calcium, not iron as the product name suggests. Our assessment is that this product is designed to support bone health through calcium supplementation, but you must be aware of the specific risks and interactions associated with calcium intake [NIH ODS].
How it works
Think of calcium as a structural architect for your skeleton. It works through bone mineralization to support bone density and mineral deposition, and it also plays a role in neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High blood and urine levels of calcium 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] [FDA data].
Our recommendation
We recommend you consult your healthcare provider before taking this supplement, especially if you take bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin, as calcium can reduce their absorption [NIH ODS]. Data on the specific iron content of GNC Ultra Iron 65 is not available, so do not rely on this product for iron supplementation.
