About this product
From The Feed's product listing:
Proferrin ES is the original heme iron formula that's been rebuilding ferritin levels for athletes since 1998. This tablet has quietly delivered results for over two decades—the same 10.5mg of highly absorbable heme iron that established the brand's reputation for actually working when standard iron supplements fail. Proferrin ES delivers heme iron through your body's natural absorption pathway , the same system that processes iron from a steak. Clinical studies show heme iron absorption rates of 15-35%, compared to just 2-10% from standard iron supplements. This isn't incremental improvement—it's a completely different approach that sidesteps the gut issues forcing most athletes to quit their iron supplementation. What Makes ES Different Original Tablet Formula – The tablet format offers an alternative to capsules for athletes who prefer swallowing coated tablets over gelatin capsul
