Fig. 1From: Dietary thiols in exercise: oxidative stress defence, exercise performance, and adaptationSummary of thiol metabolism and resulting thiol antioxidants. Methionine is metabolized to cysteine which further forms endogenous antioxidants taurine and glutathione via two distinct pathways. Supplementing with taurine and/or cysteic acid may ‘spare’ cysteine, upregulating GSH synthesis, thus further boosting endogenous antioxidant defenceBack to article page
