5-HTP has shown some usefulness in some conditions characterized, in part, by serotonin deficits, principally depression. It has also been shown to be useful in some with obesity, insomnia, fibromyalgia and chronic tension headache.
Physicians Desk Reference (PDR) for Nutritional Supplements 1st ed, Medical Economics, Thomson Healthcare; Montvale, NJ p.4 (2001)
It has been long known that brain serotonin systems contribute to the modulation of food intake and satiety. An increase of intrasynaptic serotonin tends to reduce food consumption. Thus, one might consider that individuals taking 5-HTP might experience increase satiety and weight loss over a period of time. There are few studies on the effects of 5-HTP on obesity and they suggest an anorectic effect of 5-HTP.

There is some evidence that 5-HTP ... can improve postural equilibrium, dysarthria in patients with various inherited and acquired cerebellar ataxias, and particularly in those with lesions located precisely in the anterior lobe vermis. Improvements in coordination have been reported in patients with Friedreich"s ataxia; however, the effect is only partial and not clinically major.

Exptl Ther: Rats of the Dahl salt-sensitive (DS) and Dahl salt-resistant (DR) strains were placed on a 4% NaCl diet and blood pressures were monitored. Chronic subcutaneous infusion L-5-hydroxytryptophan (L-5-HTP, 12.6 mg/day) by osmotic minipumps significantly decreased the elevated systolic blood pressure of DS rats on a 4% NaCl diet. Blood pressures of DR rats were unaffected by treatment with L-5-HTP. Cardiac hypertrophy was associated with Dahl salt-induced hypertension. However, treatment with L-5-HTP failed to reduce the weight of the heart significantly. These results suggest that chronic administration of L-5-HTP was effective in reducing the elevated blood pressure in the DS model. The specific mechanisms by which L-5-HTP reduces the elevated blood pressure in DS rats is not clear and remains for further study.

Other reported side effects, include nausea, diarrhea, loss of appetite, vomiting and difficult breathing. Neurological side effects, including dilation of the pupils, abnormally sensitive reflexes, loss of muscle coordination and blurring of vision, have been reported in those taking large doses of 5-HTP. Cardiac dysrhythmias have also been reported.
Physicians Desk Reference (PDR) for Nutritional Supplements 1st ed, Medical Economics, Thomson Healthcare; Montvale, NJ p.5 (2001)
Eosinophilia and eosinophilia-myalgia syndrome (EMS) have been reported in those taking 5-HTP. The eosinophilia myalgia syndrome is similar to that caused by L-tryptophan and was linked to contaminants in the 5-HTP preparation, rather than 5-HTP itself. Changing the 5-HTP lot in one group of patients resolved the eosinophilia. A scleroderma-like skin condition has been reported in some taking a combination of 5-HTP and carbidopa.

5-HTP should be avoided by pregnant women and nursing mothers.

5-HTP should be avoided by those with ischemic heart disease (history of myocardial infarction, angina pectoris, documented silent ischemia), coronary artery spasm (e.g., Prinzmetal's angina), uncontrollable hypertension and any other significant cardiovascular disease.

For use as an antidepressant, appetite suppressant, and sleep aid.
The psychoactive action of 5-HTP is thought to be due to increased serotonin production in central nervous system tissue.
Antidepressive Agents, Second-Generation
A structurally and mechanistically diverse group of drugs that are not tricyclics or monoamine oxidase inhibitors. The most clinically important appear to act selectively on serotonergic systems, especially by inhibiting serotonin reuptake.

The immediate precursor in the serotonin synthetic route, 5-hydroxytryptophan (5-HTP), labeled with 11C in the beta position, has become available for studies using positron emission tomography (PET) to examine serotonin formation in human brain. Normalized uptake and intracerebral utilization of tracer amounts of (beta-11C)5-HTP were studied twice in six healthy male volunteers, three of them before and after pharmacological pretreatments ... Pretreatments with benserazide, p-chlorophenylalanine (PCPA), and unlabeled 5-HTP all significantly increased uptake of (beta-11C)5-HTP. The utilization rates in both striatal and frontal cortex were higher than those in the surrounding brain, indicating that PET studies using (beta-11C)5-HTP as a ligand quantitate selective processes in the utilization of 5-HTP.

The efficiency of absorption of 5HTP, as well as its decarboxylation product serotonin, is approximately 47% to 84%. Absorption of 5-HTP occurs by an active transport process. 5-HTP is transported by the portal circulation to the liver where approximately 25% of an administered dose is metabolized ... . 5-HTP that is not metabolized in the liver is transported by the general circulation to the various tissues of the body, including the brain. 5-HTP readily crosses the blood-brain barrier, and is converted to serotonin in brain cells.
Physicians Desk Reference (PDR) for Nutritional Supplements 1st ed, Medical Economics, Thomson Healthcare; Montvale, NJ p.4 (2001)
5-Hydroxytryptophan is decarboxylated to serotonin (5-hydroxytryptamine or 5-HT) by the enzyme aromatic-L-amino-acid decarboxylase via a vitamin B6 dependent reaction in nervous tissue and in the liver.
5-HTP is transported by the portal circulation to the liver where approximately 25% of an administered dose is metabolized via vitamin B6-dependent L-aromatic amino acid decarboxylase to 5-hydroxytryptamine (5-HT) /serotonin/. 5-HT is subsequently metabolized to 5-hydroxyindole acetaldehyde which is rapidly metabolized to 5-hydroxyindole acetaldehyde which is rapidly metabolized to 5-hydroxyindoleacetic acid (5-HIAA).
Physicians Desk Reference (PDR) for Nutritional Supplements 1st ed, Medical Economics, Thomson Healthcare; Montvale, NJ p.4 (2001)
The possible analgesic effect of 5-HTP may be accounted for, in part, by its conversion to serotonin. 5-HTP has also been found to increase plasma beta-endorphin and platelet met-enkephalin levels, which may signify a reinforcing effect upon an endogenous analgesic effect.
Physicians Desk Reference (PDR) for Nutritional Supplements 1st ed, Medical Economics, Thomson Healthcare; Montvale, NJ p.3 (2001)
The mechanism of the possible antidepressant activity of 5-HTP is accounted for by its conversion to the neurotransmitter serotonin which plays a central role in the affective state. Antidepressants may work by either binding to one or more of the family of serotonin 5-HT receptors (5-HT1 - 5-HT7) or by inhibiting the reuptake of serotonin. ...
