where are vitamins absorbed in the digestive tract
While different vitamins and minerals are absorbed as they pass through different areas of the digestive tract (mouth, esophagus, stomach, small and large intestine), they technically never enter the bloodstream directly from the digestive system.he last part of the digestive tractâthe large intestineâis particularly important for the absorption of vitamin K, biotin, and the electrolyte minerals (sodium, chloride, and potassium).
