What the AI looks for in 5-HTP Nutritional Supplements
- Dose
- Start at 50 mg; most products and studies use 50 to 100 mg per dose, split through the day. Nausea is the most common side effect and depends on the dose.
- Source
- Labelled as derived from Griffonia simplicifolia seed. This is the standard commercial source; unclear sourcing is a quality red flag.
- Medication interactions
- Do not combine with antidepressants or other serotonergic drugs without medical advice. 5-HTP is a direct serotonin precursor and stacking raises the risk of serotonin syndrome.
Brands that matter
- Natrol: Standard and time-release versions.
- NOW Foods: Value capsules.
- Doctor's Best: Simple single-ingredient capsules.
What to avoid
- Stacking with St. John's wort or prescription antidepressants
- Unbranded products without purity testing; contaminants have been reported historically in some 5-HTP batches
Questions
Is 5-HTP the same as L-tryptophan?
No. Both are serotonin precursors, but 5-HTP is one step further along the pathway and they are not interchangeable dose for dose.
