Why DONA™ over other brands?                                                     

  • Many brands of Glucosamine will tell you that Glucosamine has been extensively studied and proven to work in Europe for many years. What they fail to mention is that the Glucosamine used in those studies is a prescription Drug called DONA™, sold in over 60 countries as a prescription drug and is available in the USA without a prescription.


  • DONA™ is the Original Glucosamine Sulfate and the World's Most Prescribed Glucosamine taken by millions around the world to help promote healthy cartilage and relief joint pain.


  • PATENTED PROCESSWhat makes it unique is that it is obtained through a patented process (two worldwide patents) and ONLY DONA™,contains the original active ingredient Crystalline Glucosamine Sulfate that has the necessary research and clinical studies supporting its effectiveness. Because of these patents, other brands will give you Glucosamine Hydrochloride and add Chondroitin Sulfate, (Sulfate is very important). However, other brands forget to mention that Glucosamine Hydrochloride is proven to be less effective in studies. Furthermore, Chondroitin Sulfate is a large molecule that is not easily absorbed. Currently, there are no peer-review published studies that show statistical evidence with this combination.


  • DONA™ is the Glucosamine Sulfate used in over 90% of all clinical studies and in the ONLY two 3-year Studies that showed the effectiveness and safety of this supplement. The result of the first 3-year study was published in The Lancet, a prestigious, international medical Journal, and showed DONA™ Crystalline Glucosamine Sulfate to be effective in improving and maintaining joint flexibility. A second 3-year study was published in the JAMA’s Archives of Internal Medicine confirming those results and “suggest that Glucosamine Sulfate could be a disease modifying agent in Osteoarthritis.” In both studies the authors states that the results cannot be generalized to other sources of Glucosamine products or to other brands.


  • FEEL BETTER AFTER TWO WEEKS – Both two 3-year studies showed that after using DONA™ for two weeks, most people felt the same symptom relief as an Anti-Inflammatory drug like ibuprofen…. and DONA™ is much easier on your stomach than Non-Steroidal Anti-Inflammatory drugs.


  • A 8-year observational study has shown a 57% decrease of total joint replacement for patients on a long-term daily DONA™ regimen.
