You need energy to do everything you want to do in life. Nourishing, well balanced meals and sufficient sleep and exercise are essential, but the stress of our busy lifestyles can sometime drain us of energy. The B-complex of vitamins play crucial roles in the body, including their involvement in the biochemical process of converting carbohydrates to glucose for energy. Because these vitamins are water soluble, they are not easily stored in the body, and we are forced to take in a steady supply. Keep your energy up with Quest’s superbly formulated, premium quality B - complex supplements.
