glutathione is an example of what kind of peptide question 2: The molecule shown below known as Glutathione - The Tripeptide Antioxidant

The gut and the brain are in constant biochemical conversation through the vagus nerve, the immune system, the enteric nervous system, the bacterial metabolites that cross into circulation, and the inflammatory cytokines released when intestinal barriers fail

The key advantage of Cystector over cpCys203 is its higher selectivity towards cysteine over the highly abundant glutathione: while the FRET sensor responds more to 10mM glutathione than for 100M cysteine, Cystector response to 10mM glutathione is equivalent to the one of 10M cysteine, a 10-fold lower concentration

In order to reduce oxidative stress (and thus slow down hair loss), you should replenish l-glutathione in your body
