I do not believe they are a waste. I am into Natural/Alternative medicine.
I used to not believe into until a sickness developed that nothing medical science done worked, infact many times got worse.
I would not buy anything but from a Natural Health store (NOT GNC, Walmart etc.)
Vitamin shopp has a awesome selection of vitamins, and after 3 mths of a GOOD vitamin you should be able to tell a difference. I can tell in the way I feel (of course I sleep at least 8hrs too) my hair, nails and skin.
