Vitamins don't creat energy... in fact, if you eat a balanced diet... you have no need for vitamin supplements at all.

If you are eating a well-balanced diet and you are still having problems with your energy it is because the food that we eat doesn't have the nutrients in them like they used to a long time ago because of soil depletion, mass producing, and the use of pesticides. It is a good idea to take a liquid supplement. I have been taking this liquid nutrition program (http://myhealthessentials.blogspot.com/2006/01/what-is-vemma.html) for 5 years now, and it has really helped me with my energy. It's convenient and it tastes good. I used to be tired all the time, and it really has helped me with my energy.
