I do exactly the same as cookiemonster. Just make sure you have plenty of fibre because iron can cause constipation. Eating foods rich in vitamin c with things rich in iron is a good idea too, vitamin c helps with iron absorption. Meat is the best source of iron (haem iron), though other sources (non haem iron) are spinnach, broccoli, almonds, cashews, lentils/chickpeas/soybeans etc...
