I took ferrous sulphate for 3 months because I had iron deficiency anaemia. Apart from turning my poo black, I had no side effects. And I have Crohn's so you'd think if anyone was going to get side effects, a Crohnie would! I just made sure I took my pills with food. I know dairy inhibits absorption, but I tried to cancel that out by drinking juice with my pills (vit c increases absorption).

But please go to your doctor and get checked out, as it could be something else causing your dizziness!
