Research

Our Rosa canina AP-4® rosehips contain key polyphenols central to performance, recovery, and joint health - quercetin, catechin, gallic acid and proanthocyanidins.

Quercetin → inflammation / healthy ageing
Catechin → blood flow / fatigue
Gallic acid → cellular protection
Proanthocyanidins → tissue strength / circulation support

Quercetin

Quercetin is a key polyphenol in Rosa canina rosehips with strong antioxidant and anti-inflammatory activity. It helps neutralise oxidative stress and modulate inflammatory pathways, supporting cellular protection under physical stress (learn more).

Recent research suggests that quercetin can modulate cellular autophagy pathways, partly through mTOR-related signaling - a process linked to cellular maintenance and healthy ageing (learn more).

Catechin

Catechin is a naturally occurring polyphenol in Rosa canina rosehips known for its role in cellular protection and vascular function.

It helps support blood flow and reduces oxidative stress during physical exertion (read more).

Gallic acid

Gallic acid is a phenolic compound in Rosa canina rosehips associated with cellular protection against oxidative damage.

It helps limit cellular stress and supports stability of cells under physical strain.

Proanthocyanidins

Proanthocyanidins are polyphenols in Rosa canina rosehips known for their ability to interact with structural proteins and support connective tissue integrity. They contribute to maintaining the strength and stability of tissues under mechanical stress (learn more).
