This botanical derivative is derived from the fruit of Rosa canina, collected and processed with advanced technology of plant extraction . It is a natural nutrient source, meeting the modern consumer demand for clean-label alternatives to synthetic ascorbic acid.
Our product overcomes major industry problems: raw fruit powders degrade over time and synthetic vitamins don’t have the synergistic chemicals found in whole-plant extracts. You get a shelf-stable, standardized version that has strong antioxidant activity throughout the life of your product.
This extract is rich in bioavailable vitamin C, polyphenols and galactolipids and is a multifunctional ingredient for immune support, joint health and skin rejuvenation formulations.

The Rose Hip Extract Powder provides a complete phytonutrient matrix that goes beyond the average vitamin supplement:
Natural Vitamin C is 10% to 25% better than separated ascorbic acid, and absorbs better. The total polyphenols are 15-30%, which include gallic acid, ellagic acid and chlorogenic acid, which neutralize free radicals in neurological tissues.
The extract contains 8–20% flavonoids that include quercetin, kaempferol and rutin, which are all known to have anti-inflammatory qualities. Carotenoids (lycopene and β-carotene) 3–10% Natural colour and antioxidant protection.
Additionally, 5–12 % of rosehip polysaccharides with molecular weights 10–50 kDa are obtained, showing immunomodulatory action in preclinical experiments. Organic acids (citric and malic acid) 5–12% Improve mineral absorption and add a natural tartness for beverage applications.
This synergistic combination accounts for the superior tolerance and efficacy observed in clinical trials compared to single synthetic drugs.
