Effects of Nicotinamide Riboside on Endocrine Pancreatic Function and Incretin Hormones in Nondiabetic Men With Obesity
Objective
To test whether NAD+ precursor supplementation with NR affects β-cell function, α-cell function, and incretin hormone secretion as well as circulating bile acid levels in humans.
Study Design
Randomized, double-blind, placebo-controlled, parallel assignment study in 40 healthy, obese sedentary men
Dose
2000 mg
Duration
12 weeks
Key Outcomes
NR supplementation did not affect fasting or post-glucose challenge concentrations of glucose, insulin, C-peptide, glucagon, GLP-1, or GIP.
β-cell function did not respond to NR intervention and no changes in circulating adipsin or bile acids were observed.
