A 2026 study comparing commercially administered NAD+ IV and nicotinamide-riboside IV offered preliminary short-term safety and tolerability information
Enhanced expression of GSH metabolism enzymes including glutathione peroxidases, gamma-glutamyl cysteinyl synthetase (gamma-GCS), glutathione S-transferases (GST), and ABC-family membrane transport proteins including the multidrug resistance-associated protein (MRP) were all documented to play prominent roles in cellular resistance to oxidative stress
