The Essential Vitamins We Need: A Comprehensive Guide

Vitamins are essential organic compounds that our bodies need in small amounts to function properly. They play a crucial role in growth, immune function, metabolism, and overall well-being. Since our bodies cannot produce most vitamins in sufficient quantities, we must obtain them from our diet or supplements.

This article explores the 13 essential vitamins, their benefits, food sources, deficiency symptoms, and daily requirements.

1. The Two Types of Vitamins

Vitamins are classified into two main types:

A. Fat-Soluble Vitamins

✔ Stored in body fat and the liver.
✔ Absorbed along with dietary fats.
✔ Can accumulate in the body, so excessive intake can be toxic.

Vitamin A (Retinol)
Vitamin D (Calciferol)
Vitamin E (Tocopherol)
Vitamin K (Phylloquinone & Menaquinone)

B. Water-Soluble Vitamins

✔ Dissolve in water and are not stored in the body.
✔ Excess amounts are excreted in urine.
✔ Need to be consumed daily.
