**Vitamins** are natural substances that our body needs in small amounts to stay healthy, grow, and work properly.
They help with:
* Healing wounds
* Boosting the immune system
* Turning food into energy
* Keeping skin, eyes, and bones healthy
There are **two main types of vitamins**:
1. **Water-soluble vitamins** – Dissolve in water (like Vitamin C and B-complex)
2. **Fat-soluble vitamins** – Stored in fat (like Vitamins A, D, E, and K)
We get vitamins from foods like fruits, vegetables, milk, eggs, meat, and grains.
