 L-Tryptophan is an essential amino acid which has a role in brain serotonin synthesis and is an important factor involved in improving mood, behavior, and cognition.

L-Tryptophan is an essential component of the human diet and is critical in a number of metabolic functions and has been widely used in numerous research and clinical trials. L-Tryptophan is found in foods like turkey, chicken, meat, cheese, yogurt, eggs, and fish. L-Tryptophan is the sole precursor of serotonin and once consumed, it is distributed throughout the human body in the circulatory system. The body uses L-Tryptophan and turns it into a B vitamin called Niacin. Niacin plays a key role in creating serotonin, a neurotransmitter that’s associated with sleep and melatonin production.

What is L-Tryptophan?

 L-Tryptophan is an essential amino acid that helps the body make proteins and certain brain-signaling chemicals. The body changes L-Tryptophan into a brain chemical called serotonin. Serotonin helps control mood and sleep activities in the brain.

L-Tryptophan Benefits and Uses

  • Supports a positive mood and healthy sleep
  • Supports pain management for severe PMS symptoms
  • Promotes athletic performance
  • Supports smoking cessation

Additional Information on L-Tryptophan

L-Typtophan is an amino acid, a protein building block that can be found in many plant and animal proteins. L-Tryptophan is called an “essential” amino acid because the body can’t make it and it must be acquired from food. After absorbing L-Tryptophan from food, our bodies convert it to 5-HTP (5-hyrdoxytryptophan), and then to serotonin. Serotonin is a hormone that transmits signals between nerve cells  and changes in the level of serotonin in the brain can cause blood vessels to narrow and alter mood.
