hello, a few weeks ago somebody on this forum was writing about having glutathione nebulizing for years. i have bought the brand theranatural-L-glutathione plus capsules but have not used it yet. i know it should be mixed with sodium chloride but i dont think that person said what % sodium. I have been using NAC600 mg once a day and mucinex for over a year. Sue do you use NAC once a day?
