What is Turkey Tail mushroom?
Turkey Tail (Trametes versicolor) is a colourful fan-shaped fungus that grows on dead trees and logs worldwide. Its overlapping caps in shades of brown, beige, grey and green resemble a wild turkey’s tail — hence the name.
It contains an impressive range of bioactive compounds: polysaccharides, beta-glucans (including PSK — polysaccharide-K), triterpenoids and flavonoids. In Japan, PSK extracted from Turkey Tail became a popular immune-boosting supplement after researchers isolated it during World War II. In traditional Chinese medicine it was used to support immunity, digestion and overall vitality.
Benefits of Turkey Tail mushrooms
Immune system support
Turkey Tail’s beta-glucans and polysaccharides stimulate immune cells including macrophages and natural killer cells, and increase cytokine production — signalling molecules that regulate immune response. An 8-week study of 24 healthy people found that 3,600 mg of PSP (a Turkey Tail polysaccharide) daily led to beneficial changes in gut bacteria and suppressed growth of pathogenic E. coli and Shigella.
Athletic performance
Turkey Tail may benefit mitochondrial function and has adaptogenic properties that help the body adapt to stress and reduce fatigue. A mouse study found Turkey Tail extracts improved exercise performance, reduced fatigue and lowered blood sugar at rest and post-exercise.
Antioxidant protection
PSK in Turkey Tail has potent antioxidant effects — scavenging free radicals and reducing oxidative stress. Additional antioxidants including flavonoids, phenols and tocopherols work together to support liver health, gut health and immune function.
Cardiovascular support
Turkey Tail may have mild hypotensive properties — compounds may relax blood vessels and inhibit enzymes that raise blood pressure. Anti-inflammatory and antioxidant properties may also support healthy cholesterol levels.
Anti-cancer research (exploratory)
Turkey Tail is not a cancer treatment. However, PSK has been studied as an adjunct to conventional cancer therapy in Japan. A test tube study found Turkey Tail inhibited the growth and spread of human colon cancer cells via angiogenesis and apoptosis mechanisms. If you are receiving cancer treatment, always consult your oncology team before using Turkey Tail.
