Even as the National Cancer Institute attempts to discredit vitamin E by deceptively using synthetic vitamin E in its studies, the real truth about natural vitamin E continues to come out: It slashes lung cancer risk by a whopping 55 percent. It also slashes the risk of other cancers, but only if you use the natural form of vitamin E, not the synthetic form. The National Cancer Institute knows this, of course, but they continue to use synthetic vitamin E anyway, since the whole purpose of their own studies is to discredit vitamin E rather than conduct actual science.
