Researchers found that sporoderm-removed Ganoderma lucidum spore powder (S-GLSP) protects against Alzheimer’s disease by reducing brain inflammation. The supplement works by shifting immune cells in the brain called microglia from a harmful pro-inflammatory state to a protective anti-inflammatory state. This is accomplished by blocking the NLRP3 inflammasome, a key trigger of brain inflammation. In animal and cell studies, S-GLSP improved memory, reduced neuronal damage, and decreased harmful tau protein accumulation.
