Im 21 years old what benefits will taking vitamin b12 pills and fish oil pills do for me? i need more energy. what supplements can i take? thanks.

Living Life: I know of no physician that would recommend vitamins or supplements to a healthy 21 yo male. Energy comes from being active, getting good sleep unencumbered by alcohol or other drugs. The most accurate advice would also to be living a life that includes very little sugars and regular cardiovascular exercise. One should not assume that pills will give you good health. Good health activities do.
