Niacin (Vitamin B3)

Niacin, also known as Vitamin B3, is found in many foods in our diets, such as red meat, fish, brown rice, buts, seeds, and bananas. B vitamins are thought to increase energy, but Niacin’s claim to fame is that it works as a “coenzyme”, meaning that it’s needed to make other enzymes and amino acids work properly in the body. Niacin is important, and not getting enough of it may play a role in depression, headaches, and fatigue.

Creatine

Creatine is one of the most effective supplements for building muscle mass, and it's also involved in the process of storing energy in the body. More energy means you can finish that workout, build strength, for for a longer run, or even just get through the rest of the day in one piece. Creatine is also known for helping provide higher sprinting ability, muscle endurance, and resistance to fatigue.
