Rosehip (Rosa canina) is used in pet foods as a botanical ingredient that provides vitamin C, antioxidant support and joint-supportive compounds. The fruit is rich in ascorbic acid, carotenoids, polyphenols and galactolipids. In particular, the galactolipid fraction GOPO® has drawn attention for its potential to help reduce osteoarthritis symptoms. Dogs and cats can synthesize vitamin C endogenously, but additional support may still be helpful during stress, illness and aging.
| Scientific Name | rosa canina |
| Resource Type | Herbal (Fruit) |
| Function | Antioxidant / Vitamin C / Joint Support |
| Vitamin C | ~1000-2000 mg/100g (dried) |
| Active Ingredient | GOPO® (galactolipid), polyphenols |
| Endogenous Synthesis | Dogs and cats produce vitamin C |
| Discussion Level | low |
Rosehip is a safe and versatile botanical additive. It has high antioxidant potential and there is some scientific support for joint benefits. The amount present in a formula may not always reach a therapeutic level, but it is generally considered a useful and low-risk ingredient.
Why Added?
- Natural vitamin C: Alternative to synthetic ascorbic acid, highly bioavailable form
- Antioxidant: Carotenoids and polyphenols reduce oxidative stress
- Joint support: GOPO® galactolipid relieves symptoms of osteoarthritis
- Immune support: Supports the immune system during times of stress and illness
Dosage and Oxalate Risk
Excessive vitamin C supplementation (in addition to endogenous synthesis) may increase urinary oxalate levels and may contribute to calcium oxalate stone formation. Caution should be exercised in animals with a history of urinary stones. The amount of rosehip in food is generally within safe limits.
Frequently Asked Questions
If dogs already produce vitamin C, why add it?
Yes, dogs and cats synthesize vitamin C in the liver. However, endogenous production may be insufficient during periods of stress, illness, post-surgery and aging. Rosehip provides additional antioxidant support during these periods. Additionally, its components other than vitamin C (GOPO®, polyphenols) are also beneficial.
