Why our Vitamin E is better than Synthetic form?
Synthetic Vitamin E is dl-Alpha Tocopheryl Acetate /Vitamin E Acetate. Alpha-tocopherol is the most biologically active form of vitamin E, and its natural form consists of one isomer. In contrast, synthetic alpha-tocopherol contains eight different isomers, of which only one (about 12 percent of the synthetic molecule) is identical to natural vitamin E. The other seven isomers range in potency from 21 percent to 90 percent of natural d-alpha-tocopherol.
This may appear to be arcane nutritional chemistry, but it is key to understanding how the body absorbs natural and synthetic supplements differently. Molecular structure determines how the body uses vitamin E. Researchers have found that natural vitamin E assimilates far better than synthetic versions. Specific binding and transport proteins produced in the liver select the natural d-alpha form of vitamin E and largely ignore all other forms.
