I have been taking Collagen/Keratin capsules for 2 weeks. I started taking these as a possible cure for neck pain which i have suffered from for years. I developed Sjogrens syndrome 2 years ago as a result of a nasty virus I had. I have had the dry mouth which has affected the linings of my mouth and caused bad breath. In the last year I also had dry gritty eyes, and dry vagina. After two weeks on the collagen/keratin capsules I now have saliva in my mouth! My eyes and vagina are improving with moisture too. And yes my Neck pain has practically dissappeared. Hope someone else might find this cure works for them too!!
