Antioxidant Switch On

Lion’s mane mushroom (Hericium erinaceus) peptide activated the Keap1–Nrf2 pathway, increasing key antioxidant defenses like HO-1 and NQO1 that protect cells from oxidative damage. The compound disrupted Keap1 binding, allowing Nrf2 to move into the nucleus and turn on multiple cellular protection genes. This mechanism directly strengthens the body’s ability to neutralize oxidative stress linked to aging, inflammation, and chronic disease.
