Nicotinamide Riboside for Peripheral Artery Disease: The NICE Randomized Clinical Trial
Objective
To assess the effects of NR supplementation alone and in combination with resveratrol on the six-minute walk distance in individuals with peripheral artery disease (PAD).
Study Design
Randomized, double-blind, placebo-controlled, phase II study in 90 PAD patients
Dose
1000 mg NR alone or in combination with 125 mg resveratrol
Duration
6 months
Key Outcomes
NR supplementation significantly improved treadmill walking time and the six-minute walking distance (by 17.6 meters), a clinically meaningful change.
NR effectively improved walking performance in individuals with PAD, while resveratrol did not enhance the benefits of NR.
NR combined with resveratrol did not significantly improve the six-minute walk distance compared to placebo.
