The Effects of NAD+ Boosting on Muscle Mitochondrial Function: Clinical Findings

Objectives

To determine if NR supplementation in middle-aged, obese, insulin-resistant men affects mitochondrial respiration, content and morphology in skeletal muscle.

Journal

The Journal of Physiology

Key Outcomes

Protein levels of nicotinamide phosphoribosyltransferase (NAMPT), an essential NAD+ biosynthetic enzyme in skeletal muscle, decreased by 14% with NR. However, NR supplementation did not affect NAD+ metabolite concentrations in skeletal muscle.
Respiration, distribution, and quantity of muscle mitochondria were also unaffected by NR.
