Vitamin E – all forms are important in human health
by Newsletter Editor
Doctors said each of the eight forms of vitamin E plays a unique role in human health. There are four tocopherols and four tocotrienols. Researchers measured vitamin E levels in 140 adults who were free from cognitive impairment at the start of this study.
After eight years of follow-up, doctors found, compared to those with lower levels, those with higher levels of all eight forms of vitamin E were less likely to develop cognitive impairment and had lower levels of two types of cell damage, oxidative and nitrosative—from oxygen and nitrogen—and were more likely to maintain cognitive health.
Discussing their findings, doctors said evaluating only alpha-tocopherol might not be the most accurate measure of vitamin E status in humans and recommended people maintain good levels of all forms of vitamin E.
