3 studies behind AP-4® rosehip

SUKOFLEX is backed by peer-reviewed clinical and pre-clinical research into AP-4® rosehip powder and its effects on joint comfort, mobility and inflammation. Explore the studies below.

Study 01

AP-4® rosehip powder reduces inflammation and improves joint function

A controlled study from Korea investigated the effects of rosehip powder in a rat model of osteoarthritis.

Rats were divided into groups receiving either standard rosehip powder, AP-4® rosehip powder, or placebo over 21 days (learn more).

What they measured

Knee joint swelling
Mobility (treadmill performance)
Inflammatory markers

What they found

Reduced joint inflammation
Improved mobility
Lower levels of inflammatory markers

Conclusion

These findings suggest that rosehip supplements may support joint function and help reduce inflammation.

Study 02

Rosehip vs conventional joint support: a clinical trial with 150 patients

A randomized, comparative clinical trial investigated the effects of rosehip supplementation in patients with osteoarthritis receiving standard care.

Participants were assigned to receive either glucosamine + chondroitin, rosehip, or placebo over 12 weeks (learn more).

What they measured

Pain intensity
Joint tenderness
Joint swelling

What they found

Greater reduction in pain intensity with rosehip compared to glucosamine + chondroitin
Improved joint tenderness and swelling
Better functional capacity and overall joint assessment
Both active groups outperformed placebo

Conclusion

These findings suggest that rosehip supplementation may provide greater improvement in joint-related outcomes compared to conventional glucosamine and chondroitin, while maintaining a similar safety profile.

Study 03

Rosa canina supports joint function: a placebo controlled, 89 patients

A randomized, double-blind, placebo-controlled clinical trial investigated the effects of standardized Rosa canina rosehip powder in patients with rheumatoid arthritis over 6 months.

Participants received daily supplementation with Rosa canina rosehip powder or placebo (learn more).

What they measured

Joint pain and overall condition
Physical function (HAQ)
Quality of life

What they found

Improvement in physical function (HAQ assessment)
Improved quality of life measures
Greater improvement vs placebo in physician's assessment

Conclusion

These findings suggest that Rosa canina rosehip supplementation may support functional improvements and overall joint health in individuals with rheumatoid arthritis.
