Tocotrienols are named by analogy to tocopherols (from Greek words meaning to bear a pregnancy (see tocopherol); but with this word changed to include the chemical difference that tocotrienols are trienes, meaning that they share identical structure with the tocopherols except for the addition of the three double bonds to their side chains.
For canola, corn and soy bean oils, there is more γ-tocopherol than α-tocopherol, but for safflower, sunflower and olive oils the reverse is true. [27] [28] [30] Of the commonly used food oils, palm oil is unique in that tocotrienol content is higher than tocopherol content. [30] Seed tocochromanols content is also dependent on environmental ...
The liver recognizes and preferentially re-secretes α-tocopherol into circulation, making it the most abundant vitamer of vitamin E in the blood. [2] While tocotrienols are present in lower concentrations, they have more potent antioxidant properties than α-tocopherol and can have metabolic impacts at low concentration. [4]
For everyone else, more doesn’t mean better. “Most Americans meet all of their vitamin, mineral and nutritional needs. If intake is already adequate, it is rare when more would help,” he added.

α-Tocopherol (alpha-tocopherol) is a type of vitamin E.Its E number is "E307". Vitamin E exists in eight different forms, four tocopherols and four tocotrienols.All feature a chromane ring, with a hydroxyl group that can donate a hydrogen atom to reduce free radicals and a hydrophobic side chain, along with an aromatic ring is situated near the carbonyls in the fatty acyl chains of the ...
