All L-Tryptophan Benefits/Effects/Facts & Information
L-Tryptophan is an essential amino acid that is obtained from protein sources in the diet. It leads to the production of serotonin as it is used to make 5-HTP, a direct precursor to serotonin (5-HT).
Since serotonin is important for balancing mood, L-Tryptophan is used as a supplement mainly to help symptoms involving mood disruptions. Studies have shown that L-Tryptophan is effective in reducing the symptoms of mild insomnia by reducing the time it takes to fall asleep. Additionally, L-Tryptophan is used to improve symptoms of mood disorders such as depression and seasonal affective disorder, as these are characterized by low levels of serotonin in the brain.
Research also suggests that L-Tryptophan can help reduce pain and migraines as well as weaken withdrawal symptoms in those stopping use of cigarettes or alcohol. As serotonin is also produced largely in the intestines, L-Tryptophan may be useful in improving digestion and regulating bowel function. Future studies must be conducted to verify these claims.
