Furthermore, our preliminary experiment revealed that long-term (12 weeks) supplementation of glutathione (50 mg/kg body weight) in mice did not significantly increase liver glutathione levels compared to than in controls, indicating that oral administration of glutathione does not significantly affect the glutathione levels in the liver, when sufficient amounts of glutathione can be synthesized

Researchers studying NAD+ biology or methyl-donor pools should evaluate primary sources directly and note that NNMT inhibition has distinct mechanistic implications compared to direct NAD+ precursor supplementation with molecules like NMN or NAD+ itself
ROS-induced NO inactivation can impair vascular endothelial function, contributing to various pathologies like atherosclerosis, hypertension, cardiovascular disease, and central nervous system disorders (27, 28)
