How much Rosehips should I take daily?

Introduction

Rosehips, derived from the fruit of the Rosa canina plant, are known for their high vitamin C content and potential health benefits. Recent research has explored the effects of rosehip supplementation on various health parameters, including vitamin C absorption and knee joint function.

Key Insights

Vitamin C Absorption and Antioxidant Capacity:
- Supplementing with 50 grams of rosehip powder daily (equivalent to 250 mg of vitamin C) significantly increases serum vitamin C levels and reduces oxidative stress in horses over a period of 14 to 84 days.
Knee Joint Function:
- A daily intake of rosehip powder for 12 weeks significantly improves knee joint function and dynamics during walking in individuals with knee-related walking limitations. This includes increased knee joint moments and more knee joint flexion compared to a placebo group.

Conclusion

Based on the available research, a daily intake of 50 grams of rosehip powder (equivalent to 250 mg of vitamin C) appears to be effective in increasing serum vitamin C levels and improving knee joint function. This dosage has shown significant benefits in both antioxidant capacity and biomechanical function.
