What Are Vitamins?

Vitamins are tiny but mighty nutrients that your body needs in small amounts to work properly.

Different Types of Vitamins

There are two main categories of vitamins:

  • Fat-soluble vitamins: These vitamins (A, D, E, and K) can be stored in the body’s liver, fatty tissue, and muscles. They are best absorbed when consumed with healthy fats.
  • Water-soluble vitamins: These vitamins (B complex and C) are not stored in the body and need to be replenished regularly through diet. Excess amounts leave the body through urine.
