Short-term supplementation with vitamin E may support the function of cells lining blood cells from potential damage during the increase in blood sugar levels after eating, says a new study.

Five days of supplementation with a gamma-tocopherol-rich mixture of tocopherols maintained vascular endothelial function – the function of the cells lining blood vessels, according to findings published in the Journal of Nutritional Biochemistry .

The vitamin E supplement was also associated with supporting blood flow in the arteries and a reduction in increases of malondialdehyde (MDA – a reactive carbonyl compound and a well-established marker of oxidative stress).

This study demonstrates that short-term gamma-tocopherol-rich mixture of tocopherols supplementation in healthy men maintains vascular endothelial function that is otherwise impaired by postprandial hyperglycemia likely by decreasing lipid peroxidation […] without affecting inflammatory responses,” report researchers from the University of Connecticut (USA) and Changwon National University (South Korea).
