Vitamins: What and how much should I be taking?

I've come across this incredible site www.vip-vitamins.com and ordered cos I find my monthly cost of vitamins to be too much. If you're buy your vitamins from any popular vitamin chain store, most likely, you'd notice that the vitamins in store are:

- overpriced, if recently manufactured
- probably been sitting on the shelf for too long and hence discounted
- not sufficient and never satisfy your needs in one bottle

Check this site out, if you answer the health survey, they'll tell you what you should be taking! L-Carnitine for eg... never heard of it until now, and never in your multi-vits. Feeling goooood
