Vitamins are the foundation of good health. They fuel your body, boost your immunity, and keep your organs functioning optimally. Without them, you may experience fatigue, weakened immunity, and other health issues. Let’s dive deep into the world of vitamins and learn how they help you stay strong and energized!
What Are Vitamins?
Vitamins are organic compounds your body needs in small amounts to function correctly. They play a vital role in energy production, immune support, and cell regeneration. Unlike macronutrients like proteins and carbohydrates, vitamins do not provide energy but are essential for various bodily functions.
There are 13 essential vitamins, categorized into two groups:
- Water-Soluble Vitamins (e.g., Vitamin C and B-complex) – Not stored in the body and need to be consumed daily.
- Fat-Soluble Vitamins (e.g., Vitamins A, D, E, and K) – Stored in body fat and used when needed.
