Description: Organic Shiitake (Lentinula edodes)

Used for thousands of years in traditional Chinese medicine, shiitake (Lentinula edodes (Berk.) Pegler) is an edible mushroom rich in proteins and polysaccharides, which include lentinan, a beta-glucan with numerous medicinal properties.

Polysaccharides in shiitake act as powerful immunomodulators. In addition to being rich in vitamins and minerals, shiitake is an excellent restorative and helps combat fatigue.

Shiitake also has antibiotic, antiviral, antithrombotic and lipid-lowering activity (reduces cholesterol levels).

Our organic shiitake extract is standardised to contain 30% polysaccharides and 15% beta-glucans, guaranteeing maximum effectiveness.

Detailed information

Description and origin

Shiitake (Lentinula edodes (Berk.) Pegler) is a fungus native to East Asia (1) and has been cultivated for thousands of years in Japan and China, where it has been used for both food and medicinal purposes. This basidiomycetic fungus grows on trees, degrading cellulose, hemicellulose and lignin in the trunks. Shiitake is also one of the most cultivated fungi in the world, second only to the mushroom (Agaricus bisporus (Lange) Sing.) (2).


Known for centuries, use of the shiitake fungus for medicinal purposes became widespread in China during the Ming Dynasty (1368-1644). Shiitake was considered a tonic capable of alleviating pain, discomfort and fatigue relating to ageing (3).


The shiitake fungus is rich in polysaccharides such as the beta-glucans lentinan and LC11. It also contains lipids, proteins, essential amino acids, vitamins (primarily from group B and D) and minerals (sodium, potassium, magnesium, calcium, aluminium, silica, iron, phosphorus and sulphur) (4).


Shiitake is a fungus with immunomodulatory, anti-bacterial and antiviral properties (4). Its polysaccharides and beta-glucans offer a range of therapeutic applications for treating hyperlipidemia and immunodepression (5).


Among the polysaccharides present in shiitake, beta-glucans have an immunostimulant function that has been studied for decades (6). Early studies into beta-glucans identified that they were capable of stimulating the mononuclear phagocytic system (cells of the immune system), boosting the general defence mechanisms and promoting resistance to tumours by activating various immune responses (6-7). Lentinan stimulates production of antibodies, and it has been observed in experiments conducted on cell cultures that it stimulates the cells of the immune system to attack cells infected by viruses (3).

According to some studies, the polysaccharides present in shiitake could also be potential prebiotics (stimulating the growth and activity of probiotics), and a recent laboratory study demonstrated the effectiveness of polysaccharides in shiitake for boosting immunity and improving intestinal health (5). Finally, the lipid-lowering activity in shiitake is also due to beta-glucans, since they reduce the absorption of cholesterol and inhibit the enzyme HMG CoA-reductase, an enzyme involved in the metabolism of cholesterol, inhibition of which reduces the serum levels of cholesterol (8).
