Ultra-pure pharmaceutical grade 5-Hydroxy Tryptophan (5-HTP) powder, for extemporaneous prescribing. 0.15ml scoop included.

5-HTP is an intermediate precursor to Serotonin in the body. It is used clinically to support balanced neurotransmitters, mood, sleep, appetite and peristalsis, among other uses.

Common Dosage Range: 50mg – 300 mg per day

(It is advisable to begin supplementation at the low end of the dose range, increasing if required).

Each bottle is clearly labelled with ingredient density, to facilitate ease of dosage calculations, and a scoop is provided with each bottle to assist with accurately determining patient doses according to your clinical judgement.



RN Labs use only the highest grade ingredients and materials available. Our purity standards for manufacturing and sourcing are extensively researched and verified.

Due to the risk of reaching excessively elevated Serotonin levels, 5HTP is contraindicated in those taking SSRI (or any other Serotonin modifying) medications. Diminish use in all other individuals who present with any symptoms of dizziness, agitation, tremor, tachycardia or diarrhoea following administration.

5-HTP has not been extensively tested for its effects during pregnancy.

Health practitioners may prefer to avoid its use during pregnancy or lactation, unless confident that its impact can be reasonably deemed to be safe or beneficial.

All RN Labs products follow the relevant Australian regulations, standards and guidelines.
