The Effects of 5-Hydroxytryptophan in Combination with Different Fatty Acids on Gastrointestinal Functions: A Pilot Experiment
Figure 2
Serotonin plasma levels. The influence of 5-hydroxytryptophan (5-HTP) and fatty acid ingestion on serotonin plasma 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). Plasma samples were taken during fasting (t1) and after 5-HTP or placebo intake after 2.5 hrs (t2), 4 hrs (t3), and 5.5 hrs (t4). The actual plasma concentrations of serotonin protein are presented as means SE. Statistics: serotonin; no statistical significance.
