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.

Proferrin ES

I feel like I have more energy after a couple weeks of taking these. I have very low iron and regular iron was not making me feel better and giving me stomach issues. I am now on my second bottle of these

It's on the pricier side, but it is the best way to increase iron/ferritin levels with stomach pain, constipation, or worrying about other supplement interactions. My teens have not complained which, if you knew them, tells the whole story.
