1. What Are Vitamins?
Vitamins are organic compounds that the body requires in small amounts to function properly. They can be classified into two categories:
- Water-soluble Vitamins: These include Vitamin C and the B-vitamins. They dissolve in water and are not stored in the body, making regular intake necessary.
- Fat-soluble Vitamins: These include Vitamins A, D, E, and K. They dissolve in fats and can be stored in the body’s fatty tissues and liver.
