So I recently got the GNC Sport Vitapack 30 pack. They asked if I was trying to lose weight and what not and pointed it out for me, said it would be best for me since Im so active. but I DIDNT know there were 7 total. Is this a little excessive or is it ok for me? lol. I normally took a One a Day sports Vitamin. I read it had NO (Nitrous Oxide "I think") and that prolonged use of it could harm the skin and so on. at any rate. are the vitapacks good for me and should I get off them after I use them all? also...are their any better vitamins to take?
