Glutathione is also a constituent in the regulation of protein and gene expression, exchange reactions including thiol to disulfide ratios involve glutathione.[4] Glutathione can exist intracellularly in either an oxidized (glutathione disulfide) or reduced (glutathione) molecular state
Initial Boost For individuals new to IV-glutathione infusions, starting with a more frequent schedule is often recommended
An open-label study (n=42) found that IV NAC (50 mg/kg) combined with oral NAC (500 mg twice daily) for 3 months increased brain glutathione levels (measured by MRS), increased dopamine transporter binding (measured by DaTscan), and improved UPDRS motor scores (Monti et al., PLoS One, 2016) [53]
So, 1000 mcg is the same as 1 mL
Research has focused on its neurophysiological implications, with studies exploring its interaction with the central nervous system and its modulation of various neuroendocrine and autonomic functions
