Just out of curiousity...I train at 5:30am every morning, when I get home around 7:30am, the 1st thing I do is take a 40g protein shake and all my vitamins. My question is, I take all my vitamins at once. Vitamin C, Vitamin E, fish oil, calcium, glucosimine, multi, and sometimes iron, I was curious if taking all these at the same time would cause them to not filter into my system properly. I know each of these has its purposes, and I want to make sure that by taking them all at once, my body is taking them as they are suppose too. May be a stupid question, but Ive always been curious.
