AST's MultiPro 32 uses natural vitamin e as dl-alpha tocopherols. Animal Pak is overpriced and overrated. I tried it for 3 months and came down with a cold twice during that period. I usually NEVER catch colds. I swear by GNC's Ultra Mega Gold no Iron, it's alot more potent than your typical multi's and they use top notch ingredients in their vitamins. They are also NSF certified for ingredients (independently lab tasted). GNC's typically overpriced for sports supplements, but their Multi's, and miscellaneous sups (fish oils, glucosamine, etc.) are all legit! I get a discount cuz some of my buddies work there, so it's not that bad. The Ultra Mega Gold's usually on sale for $25-30 bucks for a 3 month supply, not bad at all!
