My absolute favorite "I'm Feeling Low and Anemic" meal is:
Blackeyed peas cooked with finely shredded bits of ham (for a slightly salty flavor) and a little garlic and sriracha sauce, until slightly thickened with their own starch over a small scoop of basmati rice, topped with chopped onion and tomatoes.
With a big bowl of slow-cooker collard greens (fill the crockpot with chopped and de-veined greens and about half way with water, toss in some chopped lean ham steak, garlic powder, small amount of kosher salt and cracked pepper, cook on high for about 4 hours...) with a sprinkle of hot vinegar (made by the Louisiana Hot Sauce people, the stuff with the peppers in it). Add in a Guinness and you've got your B vitamins + iron.
I get a boost for days.
When I absolutely have to (like right now), I use a chelated iron supplement because I'm allergic to iodine. It's super easy on the stomach and I typically notice a difference in about a week and then I can quit taking it again. I'm starting to get in the habit of taking it for a few days before my period to about two days after. And I'm noticing a huge difference. So, if you end up needing a boost, there are a few options. And the Vitamin Shoppe has a low dose chelated iron tablet pretty reasonable.
