vitamin E

Functions
  • Anti-oxidant and preservative: prevents oxidative damage to fatty acids (peroxidation) in body cell (phospholipids) membranes – cells at high risk from oxidative damage cells  include: erythrocytes (red blood cells), neurons (nervous system), lung epithelium (lining of the lungs)
  • Vitamin E combined with vitamin A and vitamin C are useful in protecting the heart from damage caused by chemotherapy; protects vitamin A and promotes its storag
  • Antioxidant therapy and lipid membrane repair
  • Treatment of:
    • Neuropathy, Multiple Sclerosis, Parkinson’s Disease, Tardive dyskinesia
    • Intermittent claudication (circulatory issue involving severely reduced blood flow to the extremities), Mitochondrial oxidative phosphorylation disorders
    • Immunosuppression, Autoimmune disorders
    • Macular Degeneration (caused by toxic load in eyes: smoking can cause this)
    • Alzheimer’s Disease (helps to clear inflammatory toxic plaque in the brain)
    • Infertility, Myopathy, Diabetes, Periodontal Disease
Sources notes
  • Best sources in plant and seed oils
  • Content in food lowered through heat and food processing
  • Vitamin C restores vitamin E to its normal antioxidant state: best to take together (1+1=3)
Vegetable Sources spinach; asparagus; carrots; peas; tomato
Fruit Sources banana
Nut and seed sources Sunflower seeds and oil; safflower oil; almonds; sesame oil; peanut oil; corn oil; wheat germ; peanuts; butter; pecans; walnuts
Absorption and function notes
  • More is required when intake of polyunsaturated fats is increased – acts as preservative preventing lipid oxidation
  • Fat soluble – fat enhances absorption
Deficiency factors
  • Huge range of actions attributed to this vitamin – deficiency disrupts any physiologic processes that depend on the integrity of the cell membrane
  • Symptoms: weakness; poor coordination; susceptibility to infections; poor wound healing; fatigue
  • Infant deficiency: impacts nervous system (reduced or absent deep tendon reflexes)
Toxicity
  • One of the safest vitamins
  • Vitamin E and aspirin combined may increase gum bleeding
