Turkey Tail Substances and Antioxidant System Support

Phenolic compounds in Turkey Tail mushroom, such as quercetin and baicalein, play a pivotal role in its antioxidant activity. These compounds act as electron donors, which is crucial for stabilizing free radicals. Free radicals are unstable molecules that can cause significant cellular damage. By donating electrons, quercetin and baicalein neutralize these free radicals, preventing them from interacting with and damaging vital cellular components such as DNA, proteins, and lipids.

Additionally, these phenolic compounds have the ability to regenerate other antioxidants, such as vitamin C and vitamin E, which are vital for maintaining the body's overall antioxidant capacity. This regeneration process ensures that the body has a sustained supply of antioxidants to continuously combat oxidative stress.


Flavonoids in Turkey Tail, including myricetin and catechin, also contribute significantly to its antioxidant effects. These flavonoids scavenge free radicals directly, meaning they actively seek out and neutralize these harmful molecules. Beyond direct scavenging, myricetin and catechin chelate metal ions, such as iron and copper, which catalyze the formation of free radicals through Fenton reactions. By binding to these metal ions, flavonoids prevent them from participating in these reactions, thereby reducing the overall production of free radicals.

Furthermore, flavonoids enhance the body's internal antioxidant defense by upregulating the production of key antioxidant enzymes, such as superoxide dismutase (SOD) and glutathione peroxidase. These enzymes play crucial roles in neutralizing superoxide radicals and hydrogen peroxide, respectively, which are common reactive oxygen species in the body. By boosting the activity of these enzymes, flavonoids help maintain a robust antioxidant defense system, protecting cells and tissues from oxidative damage.
