Taurine and insulin sensitivity outcomes in metabolic models

Objective: To examine whether taurine influences glucose metabolism and insulin sensitivity in experimental models of metabolic dysfunction. Rodent and cellular systems were used to assess insulin signaling, glucose uptake, hepatic glucose output, and related markers of metabolic stress after taurine exposure. Across models, taurine supplementation improved several indices of glucose handling, including insulin-stimulated signaling in peripheral tissues and reduced abnormalities in fasting glycemia in diet-induced metabolic impairment. Effects were more consistent in settings with baseline insulin resistance than in healthy controls. Mechanistic data suggested contributions from improved mitochondrial function, reduced oxidative stress, and better regulation of inflammatory pathways that interfere with insulin action. While the magnitude of benefit varied with dose, duration, and model severity, the overall pattern supports a metabolically favorable effect. These findings justify clinical trials in populations with impaired glucose tolerance or early insulin resistance, where a modest effect could have practical value.
