Background: Curcumin is a powerful anti-oxidant that can be used to treat inflammation and pain in chronic conditions such as osteoarthrosis (OA). Phytoproflex® is characterized by an innovative delivery system that improves bioavailability of curcuminoids and could be useful in the management of OA.
Methods: This 4-week registry included 56 patients with knee OA treated according to the best standard management for symptomatic OA. On top of that, 24 patients used Phytoproflex® supplement preparation (an extract containing boswellic acid 90%, curcumin 20% and valeric acid 0.8%). Patients' control of symptoms and functional capacity were evaluated through the Karnofsky Scale and standardized treadmill test, together with measurement of oxidative stress levels and use of rescue medication.
Results: No problems of tolerability or safety were reported among subjects using the supplement. After 4 weeks, patients treated with the supplement reported a significant decrease in pain (P<0.05), and a significant improvement in the fitness scale (P<0.05), indicating that subjects were able to perform normal daily tasks. Less subjects in the supplement group had to use rescue medication (P<0.05), while oxidative stress levels, which were high at inclusion, significantly decreased in both groups (P<0.05). Moreover, the variation in pain-free walking distance and the Karnofsky Scale were significantly more improved (P<0.05) in patients taking the supplement compared to controls.
Conclusions: This preliminary registry study indicates that Phytoproflex® can be safely used as an effective, supplementary management in most OA patients.
