B vitamins are found naturally in the foods we eat and are the most widely used energy supplement ingredient.
These essentially help the body convert food to energy. The jury’s still out on whether or not they increase energy levels via supplementation and the above study mentioned even proved otherwise.
Most people get adequate levels of B vitamins naturally through the diet except those that are on restrictive diets.
Other names for B vitamins:
◾niacin (B3)
◾folic acid (B9)
◾riboflavin (B2)
◾cyanocobalamin (B12)
◾pyridoxine hydrochloride (B6)
◾pantothenic acid (B5)
Vitamins B6 and B12 don’t absorb well when taken orally, so the small amounts placed in most energy drinks will likely have little chance of producing the desired effect.
