Vitamin E is a potent anti-oxidant and something every bodybuilder should be supplementing with. Bodybuilders have higher free radicals because of their hard daily training which puts stress on their body.
Rather then just take a vitamin E supplement, I would take a good quality multivitamin/mineral supplement. That way all your vitamin and mineral needs are met, not just vitamin E.
Most multivitamins on the market are crap. They are marketed to a very naive audience.
The biggest thing to look for when shopping for a multivitamin is what form the minerals are in. Most supplement companies use mineral oxides in their multi vitamin products because they are cheap. The problem with that is they only have a 2-4% absorption rate. Take magnesium or zinc as an example. Most multivitamins will have the forms of 'magnesium oxide and zinc oxide' listed.
What you want are amino acid chelates. You want to see 'magnesium amino acid chelate and zinc amino acid chelate'.
Check ruthless 3d from n2bm.com. It only contains amino acid chelated minerals. It also has higher dosages of B vitamins, vitamin C and vitamin E. It was formulated with the hard training athlete in mind.
