I am looking for alpha tocotrienol capsules.  I searched http://froogle.com,
and unfortunately, all the brands which were displayed had alpha tocotrienol
capsules with other iso-forms of vitamin E blended in. Inasmuch I am looking
for a capsule which contains ONLY alpha tocotrienol, any help in this regard
would be greatly appreciated. ny@mindspring.com

I suspect palm oil is the source and it does contain some alpha tocopherol.
You understand the suffix "ol" means other forms of the tocotrienol molecule
are present. If the name and label state tocotrienyl then it could be
only alpha tocotrienol. So these may not be blends but
rather crude fractions. I've only bought from one source.

One source of tocotrienols which contains 50 milligrams of
the palm complex has 22 mg of gamma tocotrienol, 5
mg delta, 12 mg alpha tocotrienol, and 12 mg alpha tocopherol.
It also contains additional chemicals such as squalene, phytosterols,
carotenoids, and a trace of other quinones.

ny@mindspring.com:
That's the problem:  none of the so-called "tocotrienol" supplements I've
seen are all alpha-tocotrienol.

this is nonsense.

"alpha-tocotrienol" is the chemical name of this (and only this) substance,
not of a group of substances or a mix. "tocotrienols" is a group of
substances, as is "Vitamin E".

alpha-tocotrienyl is a chemical term for a tocotrienol chemical group bound
to something else like in "tocotrienylacetate",
"alpha-tocotrienyl-5-palmitate" etc.

Yes, you right and I was quite wrong. The worst of it is that
I know should know better. It seems that years of chemistry
failed to overwrite something I learned wrong when young.

Though I will add your "alpha-tocotrienyl-5-palmitate" is
also a blooper as it either be the highly unlikely
(nearly impossible) alpha-tocotrienyl-5-palmitic acid
or it alpha-tocotrienylpalmitate or it is the
rrr-alpha-tocotrienylhexadecanoate.
Still I consider my error rather more grave than
yours.

I realise I need update on several things on
the vitamin E topic. Thank you.
