Eight-day fasting modulates serum kynurenines in healthy men at rest and after exercise

open access: yesFrontiers in Endocrinology
IntroductionTryptophan’s (Trp) metabolites are undervalued markers of human health. Their serum concentrations are modified by physical exercise and other factors, among which fasting has a well-documented role. Although this mechanism is hardly explored,
