Description: Goji (Lycium barbarum)

Our dry extract of Goji berry (Lycium barbarum) is concentrated 20:1, standardised to contain 50% in polysaccharides. It provides a dose equal to 30 g of fresh berries and 750 mg of polysaccharides.

The Tibetan Goji berries (Lycium barbarum) have been traditionally used for thousands of years in East Asia for medicinal purposes and as a healthy foodstuff. Thought to rebalance the Yin and Yang in Traditional Chinese Medicine, these berries have antioxidant, anti-aging, immunomodulating and neuroprotective properties.

A thousand-year old natural tonic used to improve longevity and health, Goji berries are a superfood with powerful antioxidant properties.

Rich in polysaccharides, carotenoids, flavonoids and vitamin C, Goji berries help the body to tackle aging, improve quality of sleep, reduce stress and combat fatigue, thus improving general well-being.

Our product has been subjected to strict quality controls that have certified it contains no heavy metals or pesticides.

Detailed information

Goji: Description and source

•    Lycium barbarum (Solanaceae family) is a plant originating from Asia and Eastern Europe. It is a bushy plant that can grow up to 3-5 metres and its fruit is a fleshy red-orange ellipsoid berry that is known as the Tibetan Goji berry, Wolfberry or Gou Qi Zi. The fruit is harvested from August to October.
•    Goji berries are currently very well-known and mainly grow in the Chinese regions of Ningxia Hui and Xinjiang Uyghur. They can be consumed in a variety of ways: raw, juiced or in an encapsulated extract (1).

Goji: History

•    Goji berries have been used for 2000 years in Traditional Chinese Medicine where they are thought to enrich Yin and are used in case of kidney, lug, liver and eye problems. They have also traditionally been used to increase longevity and tackle aging, psoriasis, allergies and insomnia (1-2).
•    They are currently very popular in Europe and North America and are considered a superfood rich in polysaccharides with antioxidant properties (2).

Goji : Composition

•    Goji berries are rich in polysaccharides (up to 23% of dried weight) and carotenoids (zeaxanthin dipalmitate, beta-cryptoxanthin monopalmitate, zeaxanthin monopalmitate, trans-beta-carotene and trans-zeaxanthin). They also contain flavonoids (myricetin, quercetin and kaempferol), vitamins (riboflavin, thiamine and ascorbic acid), cerebroside, taurine, gamma-aminobutyric acid, beta-sitosterol, betaine, scopoletin and p-Coumaric acid, as well as other metabolites.
•    Goji berries are rich in vitamin C (up to 42 mg/100 g), comparable to the content of this vitamin in fresh lemon (50 g/100 g) (3).
•    The polysaccharide content (also known as LBP) is the most important in terms of the biological action of the berries and consists of a mix of proteoglycans and branched polysaccharides.

Goji: Our extract

•    Extract name: Dried extract of Goji berries standardised to contain 20:1 and titrated to 50% in polysaccharides.
•    Scientific name: Lycium barbarum L.
•    Part used: Fruit

Goji: Benefits

•    Goji berries are used as a healthy foodstuff and medicine since they possess antioxidant, neuroprotective, immunomodulating and anti-aging properties and improve general well-being thanks to their invigorating qualities.

Goji: Use, dosage

•    One dose of our product (4 capsules) is equivalent to 30 grams of fresh berries (a daily consumption of 20-50 grams is recommended) and contains 750 mg of polysaccharides.

Goji: Studies/research

•    Studies performed on Goji berries have mostly focused on its LBP polysaccharide content (2-3). One of the principal objectives of these studies was to analyse the antioxidant and immunomodulating properties of Goji berries to tackle pathologies related to aging.
•    Research has demonstrated the effectiveness of the Lycium barbarum polysaccharide-protein complex in modulating the immune system. The effect has been noted on different parameters, such as an increase in macrophage activity and the proliferation and activity of splenocytes (3, 4).
•    Goji berry polysaccharides also help to reduce glucose (5) and lipid levels in the blood (1). One study showed that the hypoglycaemic effect is related to an increase in the use of glucose to reduce levels in the blood and also encourages the proliferation of β cells, which promotes correct secretion of insulin (5).
•    In terms of neuroprotective properties, the University of Hong Kong performed an in vitro test to study the preventative effects of Goji berry extracts on neurodegenerative diseases connected with aging, such as Alzheimer’s. They observed that the aqueous extract of Lycium barbarum reduced the activity of the JNK-1 protein, which is implicated in neurodegeneration (6).
•    Combined with polysaccharides, the flavonoids and carotenoids in Goji berries perform an antioxidant action demonstrated in vitro and in vivo due to their reductive effect on metallic ions and elimination of free radicals (1, 7).
