InterventionVitamin E
Alternate Namealpha-tocopherol
OrganismCaenorhabditis elegans
Aging PhenotypeNo effect on life-span
Allele TypeN/A
StrainN2
DescriptionTreatment with alpha-tocopherol acetate had no effect on mean or maximum life-span in worms (Adachi and Ishii, 2000).
In a previous study it was reported that treatment with vitamin E extended life-span in C. elegans (Harrington and Harley, 1988).
Gene Function
Other PhenotypesAddition of vitamin E to the diet has been shown to increase life-span in the fruit fly Zaprionus paravittiger (Kakkar et al., 1996) and the rotifers Asplanchna brightwelli (Sawada and Enesco, 1984) and Philodina (Enesco and Verdone-Smith, 1980).
Dietary supplementation with vitamin E had no effect on life-span in mice (Morley and Trainor, 2001).
