Turkey Tail

Turkey Tail is a type of mushroom (Trametes versicolor) that grows on dead tree stumps and fallen logs. It is known for its fan-like shape and colorful, concentric rings resembling a turkey's tail. It is typically dried and ground into a powder for use in supplements and foods.

Turkey Tail is often added to beverages like teas and protein drinks, as well as powdered drink mixes. Manufacturers may include it for its purported health benefits, often associated with its polysaccharide content, rather than for a specific functional property like sweetening or preserving.

Turkey Tail is generally recognized as safe (GRAS) by the FDA for use as a dietary ingredient. Research into its health effects, particularly its polysaccharide-K (PSK) and polysaccharide-peptides (PSP) content, is ongoing. Some studies suggest potential immune-modulating effects, but more robust clinical trials are needed to confirm these benefits. JECFA and EFSA have not established specific ADIs for Turkey Tail, as it is typically consumed as a dietary supplement or food ingredient rather than a food additive.
