Understanding the Basics of Vitamins and Their Importance

What are Vitamins?

Vitamins are essential organic compounds that our bodies need in small amounts for various metabolic processes, growth, and overall health. They play crucial roles in maintaining functions such as immunity, vision, and bone health.

Why are Vitamins Important?

Vitamins are vital because our bodies cannot produce enough of them, so we rely on obtaining them through diet or supplements. They act as coenzymes, facilitating biochemical reactions essential for life.

Types of Vitamins

Exploring Different Types of Vitamins and Their Functions

Fat-Soluble Vitamins

Fat-soluble vitamins (A, D, E, K) are stored in fatty tissues and the liver. They require fat for absorption and are crucial for vision, bone health, and blood clotting.

Water-Soluble Vitamins

Water-soluble vitamins (B vitamins and vitamin C) dissolve in water and are not stored in large amounts. They play roles in energy production, immune function, and collagen synthesis.
