Re: vitamin E and heart disease
x-no-archive: yes
Once upon a time, our fellow mbansch314 rambled on about "Re:
vitamin E and heart disease." Our champion being bored in
sci.med.nutrition retorts, thusly ...

The latest noise on vitamin e is that it does *not* protect
against heart disease.
>Vitamin E from the diet goes straight to the liver. The liver
>stores it.
After intestinal absorption and transport with chylomicrons,
tocopherols are mostly transferred to the parenchymal cells
of the liver, with a transfer protein that is specific for
d-alpha-tocopherol, where most of the fat-soluble Vitamin E
is stored.
I question however if you can characterize it as storage.
The liver rather than the intestine is where the body
discriminates between d-alpha-tocopherol and
d-gamma-tocopherol. The d-alpha-tocopherol form of Vitamin E
is reused, but d-gamma-tocopherol is NOT. The liver, however,
secretes all the d-gamma-tocopherol into the bile.
d-alpha-tocopherol is continually being recycled by the liver.
But, my sources of information intakes that the half-life of
d-gamma-tocopherol is only about 12 hours, while
d-alpha-tocopherol might hang around for several days, at best
(i.e., the d-alpha-tocopherol form of Vitamin E is considered
to have the highest biological activity).
If the liver truly stored vitamin E, it would be possible to
over dosage on it, like vitamin A.
