Vitamin E is a broad term for two types of fat-soluble nutrients – tocopherols and tocotrienols – each containing four different classes: alpha, beta, gamma, and delta. The most abundant forms in food are alpha- and gamma-tocopherol. The primary function of vitamin E in your body is to combat oxidative stress by blocking the activity of free radicals. Along with vitamin C, it protects fat molecules from oxidation, maintaining the structure and function of each cell. Research indicates that a ratio of gamma-to alpha-tocopherol greater than 1:1 increases levels of both tocopherols in the body and that alpha-tocopherol alone may not be adequate to combat oxidative stress. This product offers a 3:1 gamma-to alpha-tocopherol ratio!
Gamma E is rumored to be the most well-known in nature and, maybe, the best structure overall. Beside taking it inside, you can open the softgel and apply it straightforwardly to a slice or scraped spot to speed mending. I would say, it is additionally useful for dried lips.
Most vitamin E's on the market are mostly Alpha tocopherols, this is the Gamma tocopherol version. For those looking for anti-inflammatory and anti-aging properties that inhibit cyclooxygenase (COX-2), then this is the Vitamin E to go for.
I usually cycle between Source Naturals Gamma E 400 complex 60 softgels and Life Extension Gamma E 60 softgels.
I think Source Naturals is one of the better classical formula brands available and they seem to care about the different forms of their ingredients. Most of vitamin E is alpha-type. But for optimum health we need beta and delta-types as well. This complex brings it. Not many options are available, once I opted for MRM brand and that was a big mistake. With Source Naturals you are on a safer end, I think. This is a brief review but I hope still helpful to you.
