Which vitamins are classified as fat-soluble?

Vitamins A, D, E, and K are classified as fat-soluble vitamins. This classification is based on their solubility in fats and oils, which allows them to be absorbed along with dietary fats in the intestine. Once absorbed, these vitamins can be stored in the body’s fatty tissues and liver, allowing for a reserve supply that the body can draw upon when needed.

Fat-soluble vitamins play crucial roles in various bodily functions. For instance, vitamin A is essential for vision and immune function, vitamin D is important for calcium absorption and bone health, vitamin E acts as an antioxidant, and vitamin K is vital for blood clotting. The ability to store these vitamins means that they do not need to be consumed every day, unlike water-soluble vitamins, which must be replenished more frequently.

The other choices include vitamins that are either primarily water-soluble or do not belong to the fat-soluble category. By identifying the correct set of fat-soluble vitamins, one solidifies their understanding of nutritional classifications and the roles these key nutrients play in health and wellness.
