From Science Daily:

A naturally occurring vitamin, nicotinamide riboside (NR), can lower blood sugar levels, reduce fatty liver, and prevent peripheral nerve damage in mouse models of prediabetes and type 2 diabetes (T2D), according to a new study by researchers at the University of Iowa and the Iowa City VA Health Care System.

The findings provide a scientific rationale for conducting human trials to test the effects of NR on metabolic disorders including prediabetes and T2D, as well as obesity, fatty liver disease, and neuropathies.

NR is a vitamin precursor of NAD+, an important cellular metabolite that is required for cells to convert fuel into energy, but which declines with age. NR is currently attracting a great deal of attention for its potential role in improving metabolic health and promoting healthy aging.

“There is a real fascination right now in the world of personalized nutrition, biotechnology, and pharmaceutical research to find strategies to boost NAD+ levels. NR has emerged as the lead molecule to elevate NAD+ metabolites,” says Charles Brenner, PhD, professor and Roy J. Carver Chair of Biochemistry at the University of Iowa Carver College of Medicine and lead author of the new study.

In 2004, Brenner, then at Dartmouth, discovered NR as an unanticipated vitamin precursor of NAD+. In the new study, published May 27 in the journal Scientific Reports, Brenner, together with Randy Kardon, MD, PhD, and Mark Yorek, PhD, who are jointly affiliated with University of Iowa Health Care and the Iowa City VA Health System, and Samuel Trammell,…
