Figure 4

Cortisol. The influence of 5-hydroxytryptophan (5-HTP) and fatty acid ingestion on the circadian profile of saliva cortisol concentrations. Participants received a capsule with either 5-HTP or placebo (Pl). They also ingested a standard breakfast supplemented with 100 μL 13C octanoid acid and either butter (Bu) or olive oil (Oil). Saliva samples were taken during fasting (t1 at 8:00) and after 5-HTP or placebo intake after 1:45 hrs (t2), 2:45 hrs (t3), 3:45 hrs (t4), and 4:45 hrs (t5). The actual saliva concentrations of cortisol protein are presented as means SE. Statistics: cortisol; time: (F = 53.814; ).
