I have been using your InvogorFlexGS for a year now...

I have been using your InvogorFlexGS for a year now and I’m proud to say that it has helped with my rheumatoid arthritis and my osteoarthritis. As a matter of fact I am down to 2mg of Prednisone and had been taking doses of 5-20 mg until Oct of 2018. I give the credit to this form of gluocosomine. It has been effective in my knees and helped with my back pain. I can walk a mile a day without pain. Thanks for getting the information out so I could try it. After 27 years of fighting this rheumatoid arthritis everyday it is now not a fight but an easier part of my daily tasks. Thank you.

My Dr. suggested InvigoFlex GS

I started taking GS because my Dr. suggested it. I run a lot! My knees would always hurt. So my doctor recommended I start taking glucosamine. Originally he recommended DONA and I really noticed a difference, but DONA is so expensive. My doctor recommended InvigoFlex GS then. I did about 6 months and I felt great. I then didn’t take it for a bit and my knees really started hurting, so I definitely noticed a difference. I am back to taking InvigoFlex GS
