Not All Vitamin E Supplements Are Alike, Especially "Natural" Ones, Tests Reveal

White Plains, New York, August 28, 2015 — recently tested popular brands of natural and synthetic vitamin E supplements and found that not all vitamin E supplements are the same - with big differences in the types and amounts of compounds they contain. This was especially true for "natural" vitamin E which should naturally include compounds, like gamma tocopherol, not found in synthetic products. However, found anywhere from 1.8 mg to 432 mg of these other compounds per daily serving in natural vitamin E supplements.

Vitamin E supplements are relatively popular in the U.S. In a 2014 survey of supplement users, found that 18.3% reported taking vitamin E supplements. Although deficiency is rare in the U.S., vitamin E may be helpful in Alzheimer's disease, arthritis, certain types of nerve pain and other conditions. There is some evidence that natural vitamin E, with its wider range of tocopherol compounds, may provide benefits that synthetic vitamin E, which contains only alpha-tocopherol, does not. For example, natural vitamin E may lower the risk of prostate cancer, while synthetic vitamin E may actually increase the risk. Although vitamin E supplements were once touted for heart disease, research suggests little benefit -- vitamin E may even raise the risk of hemorrhagic stroke, and reduce the effectiveness of cholesterol-lowering agents.

The test results and quality ratings appear online in's new Vitamin E Supplements Review. The report covers 11 products selected by, including a topical cream and oil, and six others which passed the same tests in's voluntary Quality Certification Program.
