Because these two things are different, biological activity is lower, changing metabolism. Time may change how safe people feel.
Mixed tocopherols protect against many damage types because they contain all four types. Gamma-tocopherol reduces inflammation and nitrogen radicals better. Vitamin E is best as D-alpha-tocopherol. These chemicals are usually mixed to make healthier drugs.
