What it is

Reishi extract comes from the reishi mushroom (Ganoderma lucidum), a fungus used for centuries in traditional East Asian medicine. The extract is typically made by drying and powdering the mushroom, then using a solvent like water or alcohol to pull out beneficial compounds.

Why it's used

Reishi extract is often added to foods and beverages as a functional ingredient, believed to offer health benefits. It is most commonly found in energy bars, dietary supplements, and some drinks, where it may contribute a slightly bitter or earthy flavor.

Health notes

Reishi extract is generally recognized as safe (GRAS) by the FDA for use in certain food categories. Some studies suggest reishi may support the immune system or have antioxidant properties, but more research is needed. JECFA has evaluated reishi mushroom, but did not set a numeric ADI. Evidence regarding its long-term health effects is still developing.

Allergen info

Reishi extract is derived from mushrooms, which are not one of the FDA's 9 major allergens. It does not contain gluten.
