Food supplements should not be used as a substitute for a balanced and varied diet.


L-Tryptophan is an essential amino acid that is converted into L-5-Hydroxytryptophan (5-HTP) in the body. 5-HTP is then converted into serotonin and melatonin. Normal serotonin levels have been associated with normal moods, appropriate appetite and weight maintenance, and proper sleep. ARG 5-HTP is derived from a plant source, and is carefully tested to ensure its purity and to guarantee the absence of contaminants.

Why support neurotransmitters with supplements?

The dietary intake of neurotransmitter precursors has been subject to questions of efficacy, and the extra ingestion of plant derived promoters of serotonin provide a way of ensuring optimal availability of essential neurotransmitters.

Supportive Recommendations

Avoid obvious sources of pollution, toxins and fumes. Air your house. Consume whole, fresh foods, and minimise all forms of refined sugar and carbohydrates and processed foods. Drink plenty of filtered water.

Cautions & Contraindications

5-HTP should not be used concurrently with any antidepressant. 5-HTP should be avoided by those with elevated cardiovascular risk, coronary artery disease, carcinoid tumor, stroke or arterial spasm, and by pregnant women and nursing mothers. Large doses of 5-HTP can trigger excess serotonin formation in peripheral tissues, with possible adverse reactions. Use only as directed.

In theory, L-tyrosine, adenosyl-L-methionine, tryptophan, vitamin B6, chromium, melatonin, niacin, SAMe, St. John's wort, herbs and supplements with monoamine oxidase inhibitor (MAOI) activity, and magnesium may increase the effects or side effects associated with 5-HTP.
