I've got got serious problems with anemia. Likely has gone on for years too.
I came close to requiring a blood transfusion a couple of months ago.
Ive been loading up on the iron-rich food sources as well as the supplements.
Talk to your pharmacist. There's several types of pills. I found that Ferrous Sulfate was a bit harsh, so I switched to Ferrous Gluconate. There's one other variety I forget the name of.
Dark leafy greens, orange vegetables, beef liver, some fish, and venison are good sources.
Also, Vitamin C helps your body retain iron.
I've been into my regimen for a few months now, and am only starting to feel the benefits.
