B vitamins are a group of eight essential vitamins with several critical functions in the body. Among the B-complex’s many critical roles are energy (protein, carbohydrates, and fat) metabolism, supporting and maintaining the healthy function of the adrenal glands, skeletal muscle function, and digestion.

While rates of metabolism and clearance differ between each B vitamin, all B vitamins are water-soluble and are thus not stored in fat. As a result, the body simply excretes excess B vitamins in the urine and requires replenishment (from food or supplements) in order to maintain the cell functions to which B vitamins contribute. Along with choline and inositol added, collectively this group of nutrients are essential for maintaining normal energy levels, cognition, mood, bodily function, and well-being.
