Compositions and methods are directed to covalent adducts between reducing agents and optionally substituted 3-hydroxyflavans, wherein the reducing agent is covalently bound to the B-ring of the 3-hydroxyflavan. Such adducts exhibit markedly increased stability towards oxidation as compared to the unmodified 3-hydroxyflavan. Particularly preferred 3-hydroxyflavans include green tea catechins, and especially EGCG, while especially preferred reducing agents include NAC and glutathione.
