Which vitamins are classified as fat soluble?

The classification of vitamins as fat-soluble is based on their solubility in fats and oils rather than water. The correct group of fat-soluble vitamins includes A, D, E, and K.

Vitamin A plays a critical role in vision, immune function, and skin health. Vitamin D is essential for calcium absorption and bone health. Vitamin E acts as an antioxidant and protects cells from oxidative damage, while Vitamin K is crucial for blood clotting and bone metabolism.

These vitamins can be stored in the body’s fatty tissues and liver, allowing the body to tap into these reserves when needed, which is a key characteristic of fat-soluble vitamins. In contrast, the vitamins listed in the other choices either include those that are water-soluble, like the B vitamins and vitamin C, or misgroup other fat-soluble vitamins.
