Description

Shiitake mushroom (Lentinula edodes) is a source of fungal polysaccharides with immunomodulating properties. It is used in herbal medicine to support the immune system and is a source of antioxidants to help protect cells against oxidative damage caused by free radicals. Shiitake contains vitamins B, C, D, and E; minerals iron, magnesium, and zinc; and omega-3 fatty acids.

These nutrients help regulate immune function in several ways, including cytokine production, immune cell activity, and antibody synthesis.

Shiitake mushrooms contain immunomodulating fungal polysaccharides such as beta-glucans.
1
Shiitake’s most active beta-glucan is lentinan, which helps activate white blood cells such as dendritic cells and macrophages. In one study, healthy adults who consumed dried shiitake mushrooms daily for four weeks had significant increases in innate immunity and gut mucosal immunity.
3
In another study with healthy older participants, six weeks of beta-glucan supplementation resulted in increased circulating B cells, part of the adaptive immune response.
5



Shiitake helps increase endogenous antioxidants such as superoxide dismutase and glutathione peroxidase.
6
In addition, shiitake is a source of antioxidants, such as the amino acid ergothioneine, which helps protect from free radicals.
