Serotonin precursor for sleep, mood, nerve irritation, and appetite regulation
5-Hydroxytryptophan (5-HTP) is the intermediate metabolite of the essential amino acid L-tryptophan in the biosynthesis of serotonin. 5-HTP is used by the human body to make serotonin, an important substance for normal nerve and brain function. The body makes 5-HTP from tryptophan (an essential amino acid) and converts it to serotonin, an important neurotransmitter (brain chemical). 5-HTP easily crosses the blood-brain barrier and effectively increases central nervous system (CNS) synthesis of serotonin. Serotonin is a key neurotransmitter, manufactured in the brain, that helps support mood and appetite balance, and sleep functions. Serotonin levels have been implicated in the regulation of sleep, depression, anxiety, aggression, appetite, temperature, sexual behavior, and pain sensation.
5-hydroxytryptophan dietary supplements help raise serotonin levels in the brain, which may have a positive effect on functions and processes including sleep, mood, anxiety, aggression, appetite, temperature, sexual behavior, and pain sensation. 5-HTP may be helpful in treating a wide variety of conditions related to low serotonin levels.
Low levels of serotonin in the brain can contribute to the development of depression. 5-HTP may be as effective as certain antidepressant drugs in treating individuals with mild to moderate depression. Depression, anxiety, mood swings, increased appetite and fatigue are all common symptoms and are all indicators of low serotonin levels. This occurs due to physical changes during this time that decrease the availability Serotonin. With 5-HTP, Serotonin levels can return to normal leading to the individual feeling normal again.
