How to take it
- Typical dose: 50-100 mg per day for mood and sleep support.
- Clinical dose: 100-300 mg per day for depression or anxiety, often divided into 2-3 doses.
- Forms: Capsules (most common, in 50 mg and 100 mg sizes), derived from Griffonia simplicifolia seed extract.
- Timing: For sleep, take 100-200 mg 30-45 minutes before bed. For mood, take in divided doses with meals. Start low (50 mg) and increase gradually.
- Upper limit: Up to 400 mg daily has been used safely for up to one year. Do not exceed 300 mg daily without medical supervision.

The science, if you're curious.
- 5-HTP is directly converted to serotonin (5-HT) by the enzyme aromatic L-amino acid decarboxylase, bypassing the rate-limiting step of tryptophan...
- Serotonin produced from 5-HTP is further converted into melatonin in the pineal gland, supporting natural sleep-wake cycles.
- Oral administration of 5-HTP has been shown to increase levels of dopamine, norepinephrine, and beta-endorphin alongside serotonin.
- Increased serotonin in the hypothalamus promotes satiety, reducing food cravings and emotional eating.
Where to find it
- Natural sources: Extracted commercially from the seeds of Griffonia simplicifolia, an African plant. The body naturally produces 5-HTP from dietary tryptophan (found in turkey, chicken, milk, and pumpkin seeds).
- Supplement forms: Capsules (50 mg and 100 mg) are the most common form. Often combined with Vitamin B6 to support conversion to serotonin.
