Because of that decision only the alpha-tocopherol portion of a Vitamin E product is considered “Vitamin E,” so, the I.U. content of Vitamin E supplements generally refers to only alpha-tocopherol. But recent research shows that the whole family of Vitamin E isomers provides valuable health benefits.
We believe that a good tocotrienol supplement is one that has little to no tocopherol, and contains the most potent delta and gamma tocotrienol. It is also important that the concentration of tocotrienols — or tocopherols for that matter — be as high as possible to ensure the greatest purity and effectiveness.
Natural Vitamin E supplements outperform synthetic forms, according to a VERIS Research Summary. Results of recent studies suggest that natural Vitamin E is more bioavailable and is retained in body tissues significantly longer than synthetic Vitamin E. These studies show that previously accepted differences were underestimated and that the bioavailability of natural Vitamin E is about twice that of synthetic Vitamin E compounds.
Vitamin E Independence Day: Mixed Tocopherols and Tocotrienols Should Be Taken Separately for Maximum Performance
Optimal Vitamin E Supplementation includes the entire Vitamin E complex – with tocopherols ingested hours apart from tocotrienols. A recent A. C. Grace webinar featuring Dr. Barrie Tan of American River Nutrition suggested tocopherols and tocotrienols be taken 4-6 hours apart.
