I am a runner and i do alot of it and i was wondering why it is inportant to have enough iron and what are the benefits from having the right amount of iron? Also i take a vitamin that has iron but it has more calcium in it and i know calcium absorbs iron so will taking this vitamin decrease the amount of iron that i intake? also is it better that i take a seperate iron suppliment to make sure i get enough so it will help?
