“For example, polyphenols in green tea activate the transcription factor Nrf2 (i.e., nuclear factor (erythroid-derived 2)-like 2), which binds to a portion of DNA called the antioxidant response element.”

“Heat exposure activates Nrf2, thereby upregulating a HSP called heme oxygenase-1, or HO-1, an enzyme that breaks down heme (a powerful pro-oxidant) to generate carbon monoxide (an anti-inflammatory gas) and bilirubin (an antioxidant).”

“Isothiocyanates react with certain regions on Keap1, eliminating Keap1’s ability to target Nrf2 for degradation – effectively serving the role of stressor. Sulforaphane, an isothiocyanate derived from broccoli and broccoli sprouts, is the most potent naturally occurring inducer of Nrf2.”

“Curcumin counters these effects by upregulating antioxidant defenses in skeletal muscle, likely mediated by Nrf2 activation. Many plant-based dietary compounds induce Nrf2 activity, including sulforaphane, a compound derived from broccoli and broccoli sprouts.”

“The authors of the study fed young and old mice either regular mouse chow or a sulforaphane-supplemented chow for 12 weeks. At the end of the study period, they assessed the animals' Nrf2 activity, mitochondrial function, and skeletal and cardiac muscle function.”

“Interestingly, sulforaphane, an isothiocyanate compound derived from broccoli, is the most potent naturally occurring inducer of Nrf2 activity. Watch this clip featuring sulforaphane expert Dr. Jed Fahey in which he describes the importance of the Nrf2 pathway.”

“Some of the molecular adaptations identified involve increased activity of sirtuins, FOXO proteins, AMPK, and Nrf2, while cellular adaptations include increased autophagy, DNA repair, and immunosurveillance, among others.”

“Other antioxidants work indirectly by activating the production of endogenous antioxidants, such as the carotenoid lycopene, which stimulates the Nrf2 pathway. These indirect antioxidants have a lower risk of suppressing exercise-induced adaptations.”

“Melatonin also detoxifies the brain of metals like iron and bolsters the activity of the Nrf2 pathway, which regulates the body’s antioxidant defense systems. Adequate melatonin levels and proper melatonin timing also synchronizes our body and brain’s circadian rhythms.”

“A 2021 study in mice found that sulforaphane, a bioactive compound derived from broccoli, mitigates age-related skin changes by activating Nrf2, a protein that participates in the body's antioxidant defense system.”
