#3 Vitamin E
A lot of controversy has surfaced in the scientific community about whether taking vitamin E supplements is beneficial or not. While most of the argument focuses on whether or not E is good for the heart, it is still a good choice for those who want to increase their energy levels. Many foods contain natural levels of vitamin E, so it is not something lots of people are lacking, but adding it to your daily routine may help circulation which should result in higher energy levels and less fatigue.
