Which vitamins are classified as water-soluble?

The classification of vitamins into water-soluble and fat-soluble categories is based on their solubility in water. Water-soluble vitamins include those that dissolve in water and are not stored in large amounts in the body, requiring regular intake through diet.

Vitamin C, also known as ascorbic acid, is a well-known water-soluble vitamin that plays a crucial role in collagen synthesis, antioxidant function, and immune function. Additionally, the B vitamins, which include B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate or folic acid), and B12 (cobalamin), are also classified as water-soluble. These vitamins are vital for energy metabolism, red blood cell production, and neurological functions.

Since both Vitamin C and the B vitamins are water-soluble, this answer is accurate and reflects the correct grouping. This classification is essential for understanding dietary needs and the potential for deficiency, as water-soluble vitamins need to be consumed more regularly compared to fat-soluble vitamins, which can be stored in the body's fatty tissues.
