Efficacy and safety of native type II collagen in modulating knee osteoarthritis symptoms: a randomised, double-blind, placebo-controlled trial
Knee osteoarthritis (OA) is the most common form of clinical arthritis in middle-aged and older individuals. Undenatured or native type II (TII) collagen derived from the chicken sternum has a good therapeutic effect on relieving severe pain of OA. Hence, the present study aimed to investigate the efficacy and safety of TII collagen (Native CT-II®) in individuals with knee OA.
Vedic conducted a 12-week randomised, double-blind, placebo-controlled, parallel-group study on 101
participants aged 40–65 years with knee OA. The participants were randomised to receive either TII collagen, glucosamine hydrochloride+chondroitin sulfate (G+C) or a placebo. The primary outcome was an improvement in the joint health of the participants assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) compared to G+C and placebo.
