Introduction: Osteoarthritis (OA) is a chronic joint disease characterized by degeneration of the articular cartilage, changes in the physico-chemical properties of the synovial fluid and macroscopical modifications of the joint. Patients with Classes I and II of Knee OA can be treated with pharmacologic therapy. Vitamin C is key for both preventing inflammatory arthritis and maintaining healthy joints with OA. Aim: The aim of our paper is to verify the effectiveness of the addition of vitamin c in nutriceutical drugs for the therapy of the knee arthritis in the young adult. Results: Group B has a lower VAS score at 6 and 12 months with p<0.05. Not statistical difference we found in KSS during all follow up. A better quality of life was founded in Group B at 12 months in group B(p<0.05) and less use of pain killers/monthly(p<0.05). Conclusion: There is no denying that vitamin C benefits everybody, whether they have arthritis or not. Therefore, it is a good idea to maintain a healthy balance of vitamin C. Without a doubt, vitamin C benefits most people with early OA.
