Liquid Vitamin B Complex contains an exceptional medley of essential B vitamins! Several important functions are performed by these vitamins in the body, such as breaking down amino acids, transporting oxygen and nutrients, and releasing energy from carbohydrates and fat. As opposed to fat-soluble vitamins, excess B vitamins (except for B12) cannot be stored in the body. Rather, if not immediately needed, they pass through your body and are excreted. The "B's" also play a crucial role in digesting fats and proteins and maintaining muscle tone in the gastric tract. Therefore, dietary sources of the B complex of vitamins are very important every day, including B12, whose levels need to be replenished in the liver to remain healthy. My Vitamin B Complex Liquid features the Vitamin B family essentials in one great tasting, convenient liquid!
