LOS ANGELES – ChromaDex Corp. (NASDAQ: CDXC), the global scientific authority on nicotinamide adenine dinucleotide (NAD) and nicotinamide riboside (NR) science, announced today the publication of a study evaluating the NAD metabolome in human liver samples from people with liver diseases including alcohol-related liver disease (ArLD). The study, published in Hepatology Communications, was conducted by a collaborative team from the University of Iowa and University of Birmingham and funded with the support of the Roy J. Carver Charitable Trust. This is the first study to evaluate the NAD metabolome in human liver samples. The research demonstrated that ArLD is characterized by depressed levels of NAD-related molecules including NAD, as well as depressed levels of intracellular NR, which is protective in rodent models of liver disease.

“Our goal of identifying the human conditions that can be treated or prevented by nicotinamide riboside (NR) supplementation depends on identifying which populations have disturbed NAD systems. Here, we have shown that a common condition, ArLD, disturbs liver NAD in a way that we believe can be addressed with NR,” reports lead investigator Dr. Charles Brenner, Roy J. Carver Chair & Head of Biochemistry at the University of Iowa, and Chief Scientific Advisor to ChromaDex. Having discovered the vitamin activity of NR in 2004, Dr. Brenner and his research team continue to make groundbreaking discoveries that reshape the landscape of what is known in the field of NAD metabolism.

This new study assessed the NAD metabolome in transplant and tissue resections from 72 patients with ArLD or four other conditions. Analysis of liver tissue from the 43 ArLD patients showed marked depletion of NAD and its precursors. Depressed NAD levels correlated with low markers of liver function, suggesting that liver NAD status is important for human health.

Dr. Andrew Shao, ChromaDex Senior Vice President of Global Scientific & Regulatory Affairs, shared, “We are grateful for the efforts of Dr. Brenner and his research team to advance the body of available human data. The findings continue to support a role for Niagen®, the only safety tested and patent protected NR, in health promotion.”
