Which vitamins are considered water soluble?

The classification of vitamins into water-soluble and fat-soluble categories is fundamental for understanding their absorption and function in the body. Water-soluble vitamins include vitamin C and the B vitamins (such as B1, B2, B3, B5, B6, B7, B9, and B12).

Vitamin C is known for its antioxidant properties and role in collagen synthesis, while the B vitamins serve various functions ranging from energy metabolism to nerve function. These vitamins dissolve in water, meaning they are readily absorbed into the bloodstream and any excess typically excreted through urine, reducing the risk of toxicity.

The other options include either fat-soluble vitamins, such as A, D, E, and K, which require dietary fats for absorption and are stored in the liver and fatty tissues, or incorrectly mix vitamin classifications. Understanding the solubility of these vitamins is important for managing dietary intake and recognizing symptoms of deficiency or excess.
