Researchers link supplement to reduced biomarkers of Alzheimer’s in the brain

For the first time, a researcher at the University of Delaware College of Health Sciences in collaboration with a team at the National Institute on Aging, a division of the National Institutes of Health, has determined that the naturally occurring dietary supplement, nicotinamide riboside (NR), can enter the brain.

The discovery was made by Christopher Martens, assistant professor of kinesiology and applied physiology and director of the Delaware Center for Cognitive Aging Research, and Dr. Dimitrios Kapogiannis, a senior investigator at the National Institute on Aging. The finding is significant because it supports the idea that NR, upon reaching the brain, can alter the metabolism of relevant biological pathways involved in neurodegenerative diseases like Alzheimer’s. Their work, supported by an NIH grant, and in part by the Intramural Research Program of the NIH National Institute on Aging, was recently published in the journal Aging Cell
