This is the first study to show gamma-tocopherol
is associated with worse lung function.
Men with the highest gamma-tocopherol
levels, those in the highest fifth of the distribution, were found to have a 5-fold greater reduction in the risk of developing prostate cancer than men in the lowest fifth.
The results were "somewhat opposite" for plasma gamma-tocopherol
levels at baseline.
In addition, taking too much alphatocopherol depletes the body of other vitamin E isomers, particularly gamma-tocopherol
Heinerman, a research at the University of California, Berkeley, showed that gamma-tocopherol
prevented nitrogen oxides from causing inflammation in the body, which alter cell's DNA.
, the major form of vitamin E in the US diet, deserves more attention.
In laboratory experiments, the gamma-tocopherol
form of vitamin E destroyed cells taken from the brains of mice.
The drug candidate, GTP-0805, is a phosphorylated variant of gamma-tocopherol
Vitamin E refers to two main compounds: alpha-tocopherol, found at high levels in sunflower oil and wheat germ oil, and gamma-tocopherol
, found at high levels in soybean and corn oils.
Vitamin E is found in whole foods in the form of gamma-tocopherol
and is a powerful antioxidant, which is why there is a great deal of interest in vitamin E supplementation.
In these mixtures, gamma-tocopherol
The Penn State study showed an increase in lutein and gamma-tocopherol
in the blood was related to a decrease in oxidized LDL (bad) cholesterol, when pistachios were eaten daily, thereby contributing to a reduced risk of heart disease.
12) Both alpha- and gamma-tocopherol
inhibited the growth of human prostate cancer cells in vitro, but gamma-tocopherol
was the more potent of the two.
A recent animal study in rats found that regular vitamin E alpha-to-copherol intake does not deplete tocotrienols and gamma-tocopherol
levels in various tissues, nor does it increase the excretion of their metabolites into urine.
The results of a study reported at the annual Experimental Biology meeting suggest a cardiovascular benefit for the form of vitamin E known as gamma-tocopherol
among individuals who had recently given up smoking.
