Shiitake mushroom extract is a concentrated form of the mushroom’s bioactive compounds, including lentinan, a polysaccharide known for its immunomodulatory and antitumor effects. Studies have shown that lentinan can improve survival rates and quality of life for patients with inoperable advanced gastric cancer. This extract is often used as a dietary supplement and has been studied for its potential health benefits, such as stimulating the immune system and reducing inflammation. Incorporating shiitake mushroom extract into your wellness routine can provide a convenient way to harness the health benefits of this powerful edible mushroom.
