products and dietary supplements. Some vitamins are made in
the human body from food products.

 Vitamins are grouped into two categories:
1. Fat-soluble vitamins
2. Water-soluble vitamins
Fat-soluble vitamins are stored in the body's liver, fatty tissue,

and K. These vitamins are absorbed more easily by the body in
the presence of dietary fat. Water-soluble vitamins are not stored
in the body.

physiological functioning and maintaining overall health. Each
vitamin has a unique function in the body, and a deficiency of any
one of them can cause various health problems.

energy metabolism, nervous system function, red blood cell production, and
DNA synthesis.
3.Vitamin C: Essential for collagen synthesis, wound healing, immune system
function, and antioxidant protection.
4.Vitamin D: Essential for bone health, immune system function, and regulation
of calcium and phosphorus metabolism.

skin health.
