Study: Vitamin E May Help Memory
As published in the journal Experimental Gerontology, researchers found that various forms of vitamin E seem to play a role in memory processes.
Traditionally, studies investigating the link between vitamin E and memory disorders have usually focused on a single form of vitamin E, namely α-tocopherol, which is also used in vitamin E supplements.
However, vitamin E exists in eight different natural forms, tocopherols and tocotrienols, all of which have antioxidant properties.
In the new longitudinal study, researchers followed a sample of 140 over 65-year-old Finnish persons with no memory impairment at the onset of the study over an eight-year period.
During the course of the investigation, researchers discovered that higher total serum levels of vitamin E, and higher levels of γ-tocopherol, β-tocotrienol and total tocotrienols in particular, seemed to protect against memory disorders.
According to the investigators, the results show that the entire vitamin E family plays a role in memory processes.
Accordingly, measuring the levels of vitamin E from serum is the most reliable way to determine whether they are sufficiently high.
The study comprised part of the more extensive Cardiovascular Risk Factors, Aging, and Dementia (CAIDE) study, which focuses on the association between the risk factors of cardiovascular diseases and memory disorders. The study was carried out in cooperation between the University of Eastern Finland, the Finnish National Institute for Health and Welfare, Karolinska Institutet, and the University of Perugia.
