What You Should Know NAD+ functions as a coenzyme for energy metabolism and activates repair proteins called sirtuins Glutathione neutralizes free radicals and supports detoxification as your primary antioxidant defense From ages 20 to 60, NAD+ drops by 50%, while glutathione synthesis decreases by 45% The molecules support one another through NADPH production pathways that regenerate active glutathione
For optimal absorption, it is generally recommended to take glutathione on an empty stomach, whether in the morning or at least two hours after your last meal at night.
Model and physiological GSSR substrates are, for example, l-cysteine-glutathione disulfide (GSSCys) 9,10,11,12,13,14,15 , coenzyme A-glutathione disulfide 3,16 , as well as S -glutathionylated serum albumin 9,11,17,18,19,20 , sirtuin 21 , sulfiredoxin 22 , and peroxiredoxins 23,24,25,26,27,28,29
It is worth noting that the Han group pioneered using small-molecule fluorescent probes to monitor the reversible redox cycles between peroxynitrite and GSH 34
