Hi Anna, 10 is very low. The tablets gave me problems in the beginning but now my system has gotten used to it and sorry if this is too much info but I now go to err poop more than usual!!! I have branflakes every morning and I think that really helps in that department.
Along with the tablets, there are the usual stuff that are full of iron such as green leafy stuff (spinich), red meat, sardines, eggs, dried apricots. These are the ones that come to mind. And vit C helps absorb the iron so orange juice is great.
