Found out im anemic, and am still feeling weak, tired, dizzy, etc. i start college monday and took a 300mg iron supplement. will i be ok by then?

Nourishment: You did not mention why you are anemic but at your age that is the first concern. Heavy menses, recent pregnancy, poor nourishment are some common culprits. Being "ok" to participate in your educational pursuits requires more than an iron supplement. Improve your food choices with nutrient dense meals: early protein, low glycemic carbohydrates throughout day, and omega 3 fats for brain!
