One of the key causes of aging is incorrect transcription of DNA by RNA to reproduce the next line in cells. Both the Alpha & Gamma forms of Vitamin E can help the tRNA read the DNA more correctly; at least in Mice. Mice are always used as a close model to humans when humans can’t be used in an experiement.

Alpha and Gamma Tocopherol Prevent Age-Related Transcriptional Alterations in the Heart and Brain of Mice
“These results demonstrate that middle age-onset dietary supplementation with alpha & gamma tocopherol partially prevent age-associated transcriptional changes and that these effects are tissue and tocopherol specific.”
