I can’t take NAC as it causes mouth sores. I’ve tried three different brands, all gave me mouth sores. But I occasionally nebulize with glutathione which is what NAC produces and I don’t get sores.

I used to have terrible osteoarthritis in fingers, knees, back and hips. Now I have absolutely none! Or if it’s there, I don’t feel it anymore.
The three things I contribute to alleviating it are keeping my vitamin D serum levels above 60 and I’m one of those lucky people who Osteo Bi Flex really works. I take the triple strength now for 10 years. Have tried going off a few times and within a month my joints are mildly inflamed and stiff but do to the vitamin D never as bad as original. I have found it takes well over a month to see the results of Osteo Bi Flex — by three months you will know how well it works.

And lastly gluten — I’m not celiac or even wheat sensitive, but going off gluten has really helped.
