I started to feel a little anemic so I started taking Prenatal vitamins for extra iron, but someone told me that most OTC prenatal vitamins (and vitamins in general) may have the right supplements but your body cannot absorb them fully, pretty much wasting money. So I need to know where to get good vitamins. Also, I was wondering if anyone knew of a good protein supplement that isn't soy-based bc too much soy is bad for the thyroid, but most other ones i've seen are whey-based or even derived from animals. I have also tried brown rice protein but to get superior protein from it you have to use a lot of it and it ruins whatever food you add it to!
