Which vitamin is not fat soluble?

Vitamin C is classified as a water-soluble vitamin, making it distinctly different from fat-soluble vitamins. Fat-soluble vitamins, which include vitamins A, D, and E, are absorbed along with dietary fat and stored in the body's fatty tissues and liver. In contrast, water-soluble vitamins like vitamin C are not stored in the body; they need to be consumed regularly in the diet. Any excess amount of water-soluble vitamins is typically excreted through urine, rather than being stored, which is a crucial distinction when considering their roles in nutrition and potential deficiencies. This fundamental difference plays a significant role in dietary recommendations and the body's handling of various vitamins.
