*Understanding Vitamin E: 

 1. What is Vitamin E?

 Vitamin E is a fat-soluble antioxidant comprising eight compounds (four tocopherols and four tocotrienols), but only alpha-tocopherol is actively used by the human body.  It protects cells from oxidative damage caused by free radicals, supports immune function, and plays roles in skin health and cellular signaling.

 

2. Health Benefits of Vitamin E

 Antioxidant Protection: Neutralizes free radicals, reducing oxidative stress linked to chronic diseases like heart disease, cancer, and cognitive decline.

 

Skin Health: Topical vitamin E may moisturize skin, reduce UV damage, and alleviate conditions like eczema and psoriasis.

 Heart Health: Some studies suggest it may lower blood pressure and reduce cardiac event risks in healthy individuals, though evidence is mixed for those with existing heart disease.

REMOVE 

PMS Relief: Combined with vitamin D, it may reduce symptoms like cramps and anxiety.

 Liver and Brain Health: May improve fatty liver disease symptoms and slow cognitive decline in Alzheimer’s (though research is inconclusive).

 

3. Dietary Sources

 Vitamin E is abundant in:

Nuts/Seeds: Almonds (7.3 mg/oz), sunflower seeds (7.4 mg/oz), hazelnuts.

Oils: Wheat germ oil (20.3 mg/tbsp), sunflower oil, olive oil.

Vegetables: Spinach, broccoli, red bell peppers.

Fruits: Kiwi, mango, avocado.

 

4. Recommended Daily Intake

Adults: 15 mg/day (22.4 IU).

Deficiency Risks: Rare but possible in fat-malabsorption disorders (e.g., Crohn’s disease), causing nerve pain, muscle weakness, or vision problems.

 

 5. Drawbacks and Risks

 Over-supplementation: High doses (>1,000 mg/day) may increase bleeding risk, prostate cancer, or mortality in certain populations (e.g., heart disease patients).

Side Effects: Nausea, diarrhea, headaches, or blurred vision.

Drug Interactions: May interfere with blood thinners, statins, chemotherapy, and vitamin K absorption.

 

6. Should You Supplement?

Food First: Most people meet needs through diet (e.g., 1 oz almonds provides ~50% RDA).

Consult a Doctor: Especially if pregnant, diabetic, or on medications.
