The difference between dl-alpha and d-alpha tocopherol is more than just a letter. It is the difference between a synthetic molecule and a natural one.
d-alpha tocopherol is the form of Vitamin E found naturally in foods. Your body recognizes it, absorbs it efficiently, and utilizes it for cellular protection. dl-alpha tocopherol is a synthetic racemic mixture — half natural, half mirror-image that your body cannot effectively use.
Research shows natural d-alpha has roughly twice the bioactivity of synthetic dl-alpha. Yet most mass-market multivitamins use the synthetic form because it is cheaper to produce.
ZENYVA uses only d-alpha tocopherol. Your cells deserve the real thing.
