While iron is better absorbed from heme (meat) sources, non-heme (plant) iron is better regulated causing less damage to the body. High iron foods include clams, liver, sunflower seeds, nuts, beef, lamb, beans, whole grains, dark leafy greens (spinach), dark chocolate, and tofu.
What have you been eating Legion? I could see someone saying no to spinach or tofu, even liver. At least have some chocolate. Who doesn't like chocolate?
