According to the Wikipedia article, that not true: "Tocotrienols are found in high concentrations in palm oil, naturally comprising high levels of the alpha-, gamma-, delta-tocotrienols with small quantity of beta-tocotrienol.[10] Other natural tocotrienol sources include rice bran oil, coconut oil, cocoa butter, barley and wheat germ.[11] Sunflower, peanut, walnut, sesame and olive oils, however contain only tocopherols.[12]"
Yep. You are right. I saw that after I posted it.
