A groundbreaking study by researchers from the University of Delaware College of Health Sciences and the National Institute on Aging (NIA) has demonstrated for the first time that nicotinamide riboside (NR), a natural dietary supplement, can penetrate the brain. This discovery suggests that NR may impact metabolic pathways involved in neurodegenerative diseases like Alzheimer’s. The research, funded by the National Institutes of Health (NIH), was recently published in Aging Cell. Nicotinamide riboside (NR) is a precursor to nicotinamide adenine dinucleotide (NAD+), a molecule essential for cel…
