Which vitamin type is water-soluble?

Vitamin C is classified as a water-soluble vitamin, which means it dissolves in water and is not stored in the body in significant amounts. Unlike fat-soluble vitamins, which include A, D, and E, water-soluble vitamins are excreted through urine, making it important for individuals to consume these vitamins regularly through their diet to maintain adequate levels. Vitamin C plays a vital role in numerous bodily functions, including the synthesis of collagen, absorption of iron, and functioning as an antioxidant.

The other vitamin types mentioned—D, A, and E—are fat-soluble. This means they are absorbed in the intestines along with dietary fat and can be stored in the body's fatty tissues and liver. Each of these vitamins serves essential roles in health but requires different dietary considerations due to their solubility.
