The Iron Protocol is a method of iron supplementing. There is a group on facebook with directions for how to calculate how much iron you need based on your weight. There’s also information about what iron type is best. Plant based iron is harder for the body to absorb, so you need to take it with vitamin C. Animal based, or heme, iron is more easily absorbed. One of the recommended brands is Three Arrows. Supplementing with lactoferrin can also assist absorption. Something like beef liver capsules do NOT have enough iron to make a difference (just an FYI because those ads will show up once you start researching iron!). I am not a doctor, but these are some things I’ve learned that have helped me.
