How many EVs do vitamins give?

Question

My friend says they give 10 each, but I thought they only gave one.....

Answer 1

All of those items give 10 EVs each. they can't give any more once your pokemon has 100 EVs in that stat though. So 10 carbos will give my pokemon 100 EVs in speed. But say he has 97 special attack evs, and I give him Calcium...In that case, he will only gain three Evs since it won't go over 100.

Just to add: the Wings in B/W add 1 EV and can be used all the way to max - see http://pokemondb.net/pokebase/22631/what-do-the-wings-do-in-black-white
