Question: is dl alpha tocopheryl acetate natural?
Answer: On a supplement label, natural vitamin E is listed as d-alpha tocopherol, d-alpha tocopheryl acetate, or d-alpha tocopheryl succinate. In contrast, synthetic forms of vitamin E are labeled with a dl- prefix. Alpha-tocopherol is the most biologically active form of vitamin E, and its natural form consists of one isomer.
