I understand your concerns. I was a little skeptical myself initially, but when I looked into it further I found it to be a legitimate company with solid scientists and respected doctors behind the products. I tend to ignore the marketing hype and just look at the scientific formula of the product. Not only does it have the riboceine, which is the GSH precursor, but also a range of supporting antioxidants and natural ingredients that assist with the production of glutathione in the body.
In fact, I was chatting to someone else with CF this week who was thrilled to find Cellgevity because he had been buying many of the individual ingredients separately, costing him hundreds of dollars each month. He said that a few years ago his health was declining rapidly and the doctors couldn't help him much. So he started doing his own research into natural supplements that could help alleviate the basic CFTR defect. What he came up was remarkably similar to the Cellgevity formula and included curcumin (shown to correct the CFTR defect), milk thistle (good for the liver), alpha lipoic acid, quercetin, resveratrol, vitamin C, grape seed extract, selenium, etc. He said the regime was expensive but had helped him increase his lung function from around 11% to nearly 50%, which is an amazing achievement.
He said the Cellgevity would actually save him a lot of money because all the components were in the one supplement. The cost is $65 per month.
As you say in your story, I think in a few years time glutathione will be considered an essential part of the treatment for CF and I believe that doctors will be checking our GSH levels as well as our lung function at check ups!
In the meantime we just have to keep sharing information and finding the best way to help ourselves!
Wishing you and your family good health
