It is sometimes called the Univeral Antioxidant, because it neutralizes free radicals in both the fatty and watery regions of cells, in contrast to vitamin C which is water soluble (most varieties)  and vitamin E which is fat soluble. It directly recycles and extends the metabolic lifespans of vitamin C and Coenzyme Q10, and it indirectly renews vitamin E.
