Which vitamins are classified as water-soluble?

Vitamins classified as water-soluble include the B vitamins and vitamin C. Water-soluble vitamins dissolve in water and are readily absorbed into tissues for immediate use. Any excess of these vitamins is typically eliminated through urine, meaning they need to be consumed regularly in the diet.

The B vitamins play essential roles in energy metabolism, nerve function, and the synthesis of DNA. Vitamin C is critical for the synthesis of collagen, acts as an antioxidant, and enhances the absorption of iron from plant-based foods.

Other groups of vitamins, such as A, D, E, and K, are classified as fat-soluble. These vitamins are absorbed alongside fats in the diet and can be stored in body tissues for later use.
