Yes it appears so, I mixed one 600 mg capsule of ALA with one 600 mg capsule of NAC. There was a marked increase in initial gastrointestinal distress, which indicates to me that more of it was reacting and being absorbed. Also it feels like there is fluid in my lungs, which is perfectly normal given that NAC is also a mucolytic agent, however what was different about this time was it came on much faster and stronger than unusual... i.e. the thiols are cleaving the disulfide bonds in my lung mucus. ALA has two thiol groups, moreover ALA can reduce oxidized glutathione (GSSG) back into reduced glutathione (GSH), by extension this probably applies to NAC as well. I'm coughing at this point due to want feels like fluid in my lungs, this was only 600 mg of ALA mixed with 600 mg of NAC.

Disulfide bond cleavage is a reductive reaction, which means my lung mucus is being deoxidized. So at least I know it works, i'm giving the combo two thumbs up due to it's synergistic action... this means you can take less.
