@paxmundi Can you get the 0.9%? Have you tried 3%? Do you have an NTM? The author mentioned a previous study which found the IS not as effective as HS. Or wasn't effective? Regardless, I would definitely be nebulizing with 3% (and 0.9% if 3% was too harsh), if I could not tolerate 7%. Just the quality-of-life graphs showed positive results for the 0.9%.

Yes, more studies are definitely needed. There was a study on inhaled ascorbic glucoside? Or something like that, very mild compared to vitamin C but don't know if it's milder than saline. I vaguely remember Dr Daly (NJG) mentioning it on one of his Brinsupri videos. Apparently, the participants that had the real stuff (not the control group), knew they had the real stuff as the effects/results were amazing. I sure would like to try that!!
