Thank you Mandy, I appreciate your response. Jarrow is the brand that my daugher uses - the same formulation you mentioned. We did start with one capsule and have worked our way up to 2 caps per day and she has been inhaling GSH and taking oral GSH/Curc for about five years. She does culture pseudomonas and although the numbers are very low - last culture was 'scant', we have not eliminated the mucoid. She has had bouts of ABPA in the past. I feel the GSH and the probiotics/supplements she is taking have definitly contributed to her good health.

Thanks again.
Judy
