|Aging Phenotype||Life-span extension|
|Description||Supplementation with vitamin E at a concentration of 25 micrograms/ml significantly increased the mean life-span of the rotifer Asplanchna brightwelli (Sawada and Enesco, 1984).|
|Other Phenotypes||Of the three life stages, the pre-reproductive, reproductive and post-reproductive, only the pre-reproductive stage was significantly extended by vitamin E supplementation. Vitamin E supplemented rotifers were larger than control rotifers in their early stages of life, but both groups attained the same size by the end of their life-span (Sawada and Enesco, 1984).|
Addition of Vitamin E to the diet has also been shown to increase life-span in the rotifer Philodina (Enesco and Verdone-Smith, 1980) and the fruit fly Zaprionus paravittiger (Kakkar et al., 1996).
Dietary supplementation with vitamin E had no effect on life-span in mice (Morley and Trainor, 2001) or C. elegans (Adachi and Ishii, 2000).
