I just came across a new book, "A Means to an End -The Biological Basis of
Aging and Death", by William R. Clark, who is a Professor Emeritus of
Immunology at UCLA.  In it he says that the efficacy of Vitamin E is dependent
on an adequate dietary source of selenium.  Also he says that Vitamin E also
interacts with Vitamin C, the latter acts somewhat like a recharger,removing 
some
of the reactive oxygen molecules from Vitamin E to itself, thereby releasing
"recharged" Vitamin E to scavenge again.  The latest Merck Manual (17th) says
that Vitamin E decreases the oxidation of serum LDL-C and suggests taking
800 IU.  It also says that 250 to 500 mg of Vitamin C increases the 
antioxidant
properties of Vitamin E.  This all ties in with the in vitro study at Keene 
University
where they found that free radicals were first picked up by Vitamin E, then
transferred to Beta carotene and then finally to Vitamin C.  Because Vitamin 
C is
water soluble, it provides a means for the free radicals to be excreted from 
the
body.  Thus that "expensive" urine with Vitamin C being "lost" may be serving 
a
very valuable and important purpose.  Maintaining serum levels of Vitamin C
throughout the day is best accomplished by taking Vitamin C three or four 
times
a day.
