The importance of considering gamma-tocopherol
in human nutrition is underscored by reports that supplementation with alpha-tocopherol in doses of 200-1,200 IU per day decreased serum levels of gamma-tocopherol
by accelerating its metabolism.
On the other hand, gamma-tocopherol
was not detected in the spontaneous fermentation.
Walnuts stand out because they contain an unusually high level of the gamma-tocopherol
form of vitamin E instead of the alpha-tocopherol form.
Seeds from Japan and China had a 10% greater delta-tocopherol concentration, while seeds from Korea had a 7% higher gamma-tocopherol
induces apoptosis in androgen-responsive LNCaP prostate cancer cells via caspase-dependent and independent mechanisms.
The levels of free and esterified phytosterols were slightly lower in the aqueous enzyme-extracted oil, but the levels of gamma-tocopherol
were significantly higher.
And baseline plasma levels of various tocopherols (forms of vitamin E) modified prostate cancer risk: Within the vitamin E group, for example, higher levels of alpha-tocopherol were protective, whereas higher levels of gamma-tocopherol
32) This anti-aging feature is associated with its sparing action on the activity of vitamin E, and is correlated with a significant increase in the levels of both alpha-and gamma-tocopherol
, as well as the total plasma tocopherol ratio with intake.
Another form of vitamin E called gamma-tocopherol
may be a useful additional treatment for asthma patients because of its antioxidant properties.
Serum alpha- and gamma-tocopherol
concentrations and risk of advanced beta cell autoimmunity in children with HLA-conferred susceptibility to type 1 diabetes mellitus.
For example, some studies suggest that the gamma-tocopherol
form of vitamin E protects the prostate.
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.
used to be viewed as having one tenth the vitamin-E activity of alpha-tocopherol.
