Study 1: 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
supplementation may support joint function and help reduce inflammation.

Study 2: 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
  • Join swelling

What they found:

  • Greater reduction in pain intensity with rosehip compared to glucosamine + chondrolin
  • 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 3: 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.
