What is Serotonin? 

<ol><li>You can’t directly get serotonin from food, but you can get tryptophan, an amino acid that’s converted to serotonin in your brain. </li><li>Tryptophan is found primarily in high-protein foods, including turkey and salmon.</li><li>But it’s not as simple as eating tryptophan-rich foods, thanks to something called the blood-brain barrier. This is a protective sheath around your brain that controls what goes in and out of your brain.</li><li>In a nutshell, tryptophan-rich foods are usually even higher in other amino acids. These other amino acids are more likely than tryptophan to cross the blood-brain barrier.</li></ol>
