What is the primary function of fat-soluble vitamins?

The primary function of fat-soluble vitamins is to support bodily functions and growth. These vitamins, which include A, D, E, and K, play crucial roles in various physiological processes. For instance, vitamin A is essential for vision and immune function, vitamin D is critical in calcium and phosphorus metabolism and supports bone health, vitamin E acts as an antioxidant to protect cells, and vitamin K is fundamental for blood clotting and bone health.

While these vitamins can also be involved in other processes such as assisting in the absorption of certain nutrients, their main role is ensuring that the body’s systems function optimally and that growth and development occur properly. This emphasizes the importance of a balanced diet that includes sources of these fat-soluble vitamins to maintain overall health and support various biological functions.
