Studies show that antioxidants can slow down and even reverse these oxidative damages. As an antioxidant, vitamin E suppresses chain initiation and/or chain propagation steps by donating its 6-phenolic hydrogen to the oxygen radicals.
Vitamin E is synthesized by plants and must be obtained from plant-based oils, seeds, fruits and vegetables as dietary sources. Our tocopherol is derived from plants.
