Introduction

Vitamin E is a fat-soluble antioxidant that plays a vital role in protecting cells from oxidative damage. It supports skin health, immune function, heart health, and neurological protection. Because it helps neutralize free radicals, Vitamin E is essential for long-term cellular health.

What Is Vitamin E?

Vitamin E refers to a group of eight fat-soluble compounds that include tocopherols and tocotrienols. Among these, alpha-tocopherol is the most biologically active form in humans.

• Main forms: Alpha, beta, gamma, delta tocopherols
• Additional forms: Tocotrienols
• Nature: Fat-soluble antioxidant

How Vitamin E Works in the Body

Vitamin E protects cell membranes from oxidative stress by neutralizing free radicals. It also works synergistically with other antioxidants such as Vitamin C.

• Prevents oxidative damage to cells
• Supports immune cell function
• Helps maintain healthy blood vessels
• Protects skin and nerve tissues

Sources of Vitamin E

• Almonds and other nuts
• Sunflower seeds
• Wheat germ oil
• Vegetable oils (sunflower, safflower)
• Spinach and leafy greens
• Avocado
