What Are Tocopherols? What Are Tocopherols What Makes Gamma Tocopherols so Important? Vitamin E activity doesn’t come from one single molecule, but from a family of related molecules called tocopherols and tocotrienols. There are four tocopherols (alpha, beta, gamma, and delta) and four tocotrienols (alpha, beta, gamma, and delta), of which only alpha-tocopherol was recognized in the 1960s, by the government, to have Vitamin E activity, which is measured in International Units (I.U.s). 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...
What Are Tocotrienols? Jump to: How do Tocotrienols Support Heart Health?* Summary:The emerging research on tocotrienols is promising; however past research and opinions have emphasized the importance of tocopherols over tocotrienols. The human body indeed prefers alpha tocopherol over any other vitamin E form; however the entire family plays synergistic roles in human health. We should not supplement with one form and neglect the other.* It is important to note that, while both tocopherols and tocotrienols do occur in nature, there is no plant that provides the entire family of tocopherols and tocotrienols in adequate amounts. Thus supplements that provide both...
Natural vs Synthetic Vitamin E – An A.C. Grace Comparison Natural vs Synthetic Vitamin E “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.”
