Why Vitamin E might slow the progress of Alzheimer's

December, 2000

A chemical called methionine (an amino acid found in beta-amyloid) may be the source of the toxic free radicals produced by the amyloid-beta peptide. Recent studies have demonstrated that higher than normal doses of vitamin E may slow the advance of Alzheimer's in some people with late stages of the disease. The current study provides a possible explanation for this link. Vitamin E, an antioxidant, appears to work by destroying free radicals (oxidants) produced by amyloid.


The study was presented at the 2000 International Chemical Congress of Pacific Basin Societies.
