Here's a breakdown:

* Organic Compounds: Vitamins are made up of carbon, hydrogen, and oxygen, and sometimes other elements like nitrogen, phosphorus, or sulfur. This distinguishes them from inorganic compounds like minerals.

* Essential Nutrients: Our bodies cannot produce vitamins on their own, so we need to obtain them from our diet. They are crucial for a variety of bodily functions.

You might also hear vitamins referred to as micronutrients, alongside minerals. This is because we need them in very small quantities.
