CCS said:But to answer your question, the most important thing is get vitamin E in the d form, not the dl form. Double check that though. The d form is the natural form, and has anti-oxidant properties.
CCS said:The dl form is the other isomer. Both can be synthesized, but the dl form just meets basic needs, whereas the d form is much healthier. Too much dl form can displace the d form out of your body.
The names of all types of vitamin E begin with either “d†or “dl,†which refer to differences in chemical structure. The “d†form is natural (also known as RRR-alpha tocopherol) and “dl†is synthetic (more correctly known as all-rac-alpha tocopherol). The natural form is more active and better absorbed. Little is known about how the “unnatural†“l†portion of the synthetic “dl†form affects the body, though no clear toxicity has been discovered.

Many doctors advise people to use only the natural, the “d†form, of vitamin E.
