Reishi Mushroom Extract

Reishi mushroom extract is derived from the reishi mushroom (Ganoderma lucidum), a fungus traditionally used in East Asian medicine. The extract is typically made by processing the mushroom's fruiting body or mycelium using water or alcohol to concentrate its beneficial compounds.

Manufacturers use reishi mushroom extract for its purported health benefits and as a functional ingredient. It is often added to beverages, supplements, and snack bars, particularly those marketed for energy, focus, or immune support.

Reishi mushroom extract is generally recognized as safe (GRAS) by the FDA for use in certain food categories. While traditionally used for various health purposes, scientific evidence for specific benefits in humans at typical dietary intake levels is still developing. The WHO/IARC has not classified reishi mushroom. JECFA has evaluated reishi mushroom and did not set a numeric limit (ADI not specified). Some studies suggest potential immune-modulating effects, but more research is needed.
