Proferrin ES- 10.5mg of high Absorbing Heme Iron Polypeptide. Made in The USA. 90 Tablets. Easy on The Gut. Not affected by Coffee, Calcium, or PPI's.

My nephrologist recommended this iron supplement to help treat my anemia because every other iron supplement I have used made me violently ill, including the IV iron I had to have four times a day while hospitalized. This supplement has a reduced amount of iron, but it is still highly effective in increasing the iron levels in my system. I take one pill every other day, and not only have my iron levels increased to normal range, I have not experienced ANY of the side effects that I have experienced in the past. This supplement does not make me nauseated at all! The only downside for me is the cost. There is no generic option, and this is the ONLY manufacturer that makes this product. I am very pleased with the results, and it is definitely worth the investment, but I do wish there was a lower-cost alternative.
