I was having short breath and cramping in my legs, started to feel tired quickly and not getting sleep, I figured out this could be due to lack of hemoglobin, I started with counter top iron supplement but that was not gentle on my tummy and not providing proper satisfaction if my body needs. I found out about Vitamatic Ferrous Sulfate with vitamin c and it has a very impressive description, and I started taking this supplement, it is gentle on my tummy and it worked wonders to my body, within a week, I started feeling a lot energy and full deep breathing and not feeling tired anymore. I wish I would have found it earlier. I am very happy with it. I will definitely recommend this product, specially to an anemic.
