GOJIRED®

Goji (Lycium barbarum) extract:
a comparative study on biological properties and healthy effects, tested with University of Calabria

 

Lycium barbarum fruits, also known as goji berries, are well known for their beneficial and healthy effects.
Gojired® extract contains many nutrients with high biological activity such as polysaccharides but it’s also rich in carotenoids:
zeaxanthin is the most represented carotenoid in the fruit (31–56% of the total carotenoid content).
Zeaxanthin preferentially accumulates in the human brain and exerts a neuroprotective activity reducing oxidative stress and regulating inflammatory damage.

Gojired® extract is obtained from Italian Goji berries cultivated in Calabria (Sibari Plain), in the Southern of Italy.


Due to its biological properties and the high level of carotenoids, Gojired® can be used as an innovative ingredient to prevent:

cognitive disorders   mental impairments   neurodegenerative diseases   oxidative damages


The antioxidant properties have been evaluated and tested in collaboration with University of Calabria using the following assays:

ORAC DPPH ABTS

Gojired® extract obtained from Calabrian Goji has higher levels of carotenoids expressed as zeaxanthin compared to other goji extracts, probably due to the sun exposure and the Mediterranean climatic conditions of Sibari Plain.

Moreover, for its carotenoid content, Gojired® can be used in cosmetic application for skin photoprotection, reducing UV-induced free radicals.
