If you were look up Medline, you would find lots
of studies on tocopherol succinate (not the more
common oily acetate) being a potent cancer fighter,
particularly prostate and breast.

Tocopherol nicotinate, the synthetic ester of niacin-bound
vitamin E made by Eisai of Japan and Mack of Germany,
is not a cancer fighter, but an atherosclerosis fighter,
and superb cerebrovascular and peripheral vasodilator,
easily outperforming ginkgo. It also knocks down Lp(a),
the "heart attack cholesterol", which no drug can do.

You can find it being sold in Japan as "Juvela" and
in Malaysia as "Hijuven", 200 mg softgels.

Mack of Germany, now under Pfizer, markets it as "Renascin"
in Euirope as 100 mg softgels.
