Essential B vitamins for the digestive system include: B1, also known as thiamine. B1 helps transform carbohydrates into energy for cells; B3, also known as niacin. This vitamin is important for many digestive tract functions, including the breakdown of carbohydrates, fats, and alcohol; B6, also known as pyridoxine. B6 helps process protein; Biotin, this B vitamin helps the digestive system produce cholesterol and process proteins, carbohydrates and fatty acids; B12, also known as cobalamin.
