Your Mood: Serotonin

As a leading producer of nootropic supplements, brain health and science guides everything we do. Our purpose is to provide the best nootropics for mood on the market.

“The only difference between a good day and a bad day is your  attitude.” — Dennis S. Brown 

 

Dopamine and Serotonin are the main neurotransmitters involved in regulating your mood. Dopamine is an excitatory neurotransmitter and creates positive feelings of motivation and drive (see Chapter 3). Serotonin is an inhibitory neurotransmitter that prevents the brain from getting out of control from fear, anxiety and worry. Serotonin’s calming effects reassure us that we will be okay and elevate our mood and self-esteem. However, 70% of people have the short form of a gene dubbed the “anxiety gene”, which results in lower serotonin levels and consequently higher baseline levels of anxiety. 

 

Serotonin has also been shown to inhibit anger and aggression and encourage social behavior. If  you have ever tried a low carb diet and found yourself abnormally irritable and antisocial, low serotonin likely is the culprit. We’ll explain why below. 

 

Serotonin is found in many cells in your body, including many that are not neurons. In fact, only  1-2% of the serotonin in your body is found in your brain. Serotonin cannot cross the blood-brain  barrier and therefore the Serotonin (5-hydroxytryptamine or 5-HT) in your brain is produced  from a pathway that starts with the amino acid Tryptophan (L-Tryptophan) through an intermediary, 5-HTP (5-hydroxytryptophan) and Vitamin B6. 5-HTP availability is the rate-limiting factor in  the synthesis of Serotonin. 

 

You want to make sure that you have plenty of 5-HTP. However, 5-HTP  is found only at trace levels in food. Since 5-HTP is synthesized from the amino acid Tryptophan  (L-Tryptophan), brain levels of 5-HTP are affected by the brain levels of Tryptophan. These levels  are controlled by how much Tryptophan is in the blood and how efficiently it is transported across the blood-brain barrier. There are two ways in which molecules can cross the blood-brain barrier:  (1) molecules can dissolve through the blood vessel walls (oxygen does this, as do most drug molecules), or (2) transporter proteins can ferry the molecule across, as in the case of glucose, amino  acids and other essential molecules. 

 

Tryptophan can be derived from proteins and from carbohydrates. A high protein diet will lead to  sharply increased levels of Tryptophan in the blood, but will actually lead to a decline in brain  Tryptophan and Serotonin levels. Other amino acids from the protein compete with Tryptophan  for transport across the blood-brain barrier by transporter proteins and suppress the entry of Tryptophan into the brain. The situation is reversed with a high carbohydrate diet that also contains  some protein. Such a diet allows Tryptophan to be efficiently transported into the brain and raises  Serotonin levels. Because of this supplementation with 5-HTP is recommended (especially if you  are doing a keto or other low carb diet) and it is recommended that you take 5-HTP right before  bed when you will not be ingesting other protein that will reduce its ability to enter your brain. 

 

Low levels of serotonin are associated with food-seeking behavior and weight gain, therefore maintaining healthy levels of serotonin should help you to keep food cravings in check and help you maintain a healthy weight.
