I did a little more reading on this last night, and have realized some things that might help me easily raise my iron levels. It seems that I'm already eating lots of iron-rich foods (eggs, beef, liver, Brussels sprouts, spinach) but not taking in important nutrients that allow me to absorb it. Plus, I may be drinking too much coffee, which leaches iron.
My current multi-vitamin does not have iron in it. I'm adding an additional multi-vitamin to my supplements, but instead of taking it in the morning when I take my calcium pill, I'm going to take this one in the evening as calcium leaches iron. I've also cut all fruit out of my diet, and cut way back on tomatoes, so I'm probably not getting enough Vitamin C, which is required to absorb iron. I never knew that, so I'm going to add tomatoes back to my eating plan. So this new vitamin has iron, C, and B12, which is also important for iron absorption.
