Natural Vitamin E Powder is an oily substance red browm or red in color with high viscosity,Its biological activity is higher than synthetic Vitamin E. Unlike its synthetic counterpart,natural Vitamin E does not contain any chemical contamination which result from the chemical syntheses process.
Naturally occurring vitamin E exists in eight chemical forms (alpha-, beta-, gamma-, and delta-tocopherol and alpha-, beta-, gamma-, and delta-tocotrienol) that have varying levels of biological activity. Alpha- (or α-) tocopherol is the only form that is recognized to meet human requirements.
