Serotonin is a chemical messenger, and is known to produce feelings of happiness. It is thought to help stabilize mood and even help support sleep. You may be familiar with SSRI drugs that help with the reuptake of serotonin. However, there are some natural ways to help support healthy serotonin levels as well. Food plays a huge role in our overall health, and supporting serotonin levels is no exception here. There are certain foods that are rich in tryptophan which is an amino acid that synthesizes serotonin. Not having enough tryptophan in the body has been linked to things like depression and anxiety, so taking a good look at your diet is an important part of supporting mental health.
