Brief summary
This study is an investigator-initiated, randomised, double-blind, placebo-controlled, cross-over human trial investigating the effect of arachidonoyl-taurine (C20:4-taurine) and oleoyl-taurine (C18:1-taurine) on GLP-1 secretion during fasting and feeding.
Interventions
Vehicle (ultrapure water with 10 % fish sauce), orally administered
Arachidonoyl-taurine (2 mg/kg) dissolved in ultrapure water with 10 % fish sauce, orally administered
Oleoyl-taurine (2 mg/kg) dissolved in ultrapure water with 10 % fish sauce, orally administered
Liquid meal with 1.5 g paracetamol. Administered with a second dose of: Vehicle (ultrapure water with 10 % fish sauce), orally administered
Liquid meal with 1.5 g paracetamol. Administered with a second dose of: Oleoyl-taurine (2 mg/kg) dissolved in ultrapure water with 10 % fish sauce, orally administered
Liquid meal with 1.5 g paracetamol. Administered with a second dose of: Arachidonoyl-taurine (2 mg/kg) dissolved in ultrapure water with 10 % fish sauce, orally administered
