In estrogen biology, GSTM1 and GSTT1 serve a specific and critical function: they conjugate the reactive quinone metabolites produced when catechol estrogens particularly 4-OHE2 (4-hydroxyestradiol) are not rapidly methylated by COMT or sulfated by SULT1A1 and instead undergo further oxidation: The oxidation cascade: CYP1B1 converts estradiol to 4-OHE2 if COMT and SULT1A1 cannot clear 4-OHE2 quickly, one-electron oxidation produces 4-OHE2 semiquinone two-electron oxidation produces 4-OHE2 quinone (4-OHE2-Q)
A landmark 2015 Cell study documenting MOTS-c as a mitochondrial-derived peptide that regulates AMPK activation and improves insulin sensitivity in mice established the scientific basis for its use in metabolic optimization protocols
GLP-1s like Ozempic and Wegovy went from clinical tools to cultural phenomena driven by creators, not clinicians
Participants consumed excess sodium, saturated fat, and calories
Additionally, liver function improved within the L-carnitine group based on MELD scores
