| Attribute | 5-Hydroxytryptophan (5-HTP) | Achiote |
|---|---|---|
| **Evidence Score** | 8/10 | 8/10 |
| **Category** | Compound | Seed |
| **Also Known As** | 5-hydroxytryptophan, 5-HTP, L-5-hydroxytryptophan, oxitriptan, Griffonia extract, 5-hydroxy-L-tryptophan, serotonin precursor | Bixa orellana, Annatto, Lipstick Tree, Urucum, Achiote Colorado |
| **Overview** | 5-Hydroxytryptophan (5-HTP) is an amino acid derivative that directly converts to serotonin in the brain, bypassing the rate-limiting enzyme tryptophan hydroxylase. This mechanism makes 5-HTP more effective than L-tryptophan for increasing central nervous system serotonin levels. | Achiote (Bixa orellana) seeds contain the carotenoid bixin and δ-tocotrienol, which scavenge reactive oxygen species and inhibit lipid peroxidation through hydrogen donation mechanisms. These compounds demonstrate antioxidant activity with ABTS SC₅₀ of 61.49 µg/mL and protective effects against oxid |
| **Mechanism of Action** | 5-HTP crosses the blood-brain barrier and converts directly to serotonin via aromatic L-amino acid decarboxylase, bypassing the rate-limiting tryptophan hydroxylase enzyme. Increased serotonin activates 5-HT1A, 5-HT2A, and 5-HT7 receptors involved in mood regulation. Additionally, serotonin converts | Bixin, derived from lycopene through carotenoid cleavage dioxygenase enzymes, and δ-tocotrienol work synergistically to scavenge reactive oxygen and nitrogen species including H₂O₂, HOCl, O₂⁻, NO, and ONOO⁻. These compounds donate hydrogen atoms to neutralize free radicals, reduce lipid peroxidation |
| **Dosage** | Commonly taken in doses of 50-300 mg per day, divided into multiple doses. Consult a healthcare provider before use. | - Common forms include whole seeds, ground powder, and infused oils.
- Traditionally ground into a paste or powder for culinary use as a natural food coloring or marinade.
- Modern culinary applications include flavoring rice, cheeses, and various Latin American and Caribbean dishes.
- Recommended d |
| **Safety** | Common side effects include nausea, diarrhea, and drowsiness, occurring in 10-15% of users at doses above 200mg daily. 5-HTP significantly interacts with SSRIs, MAOIs, and tramadol, potentially causing serotonin syndrome. Contraindicated in individuals with carcinoid syndrome due to risk of serotoni | No major safety concerns, drug interactions, or contraindications are documented in available research. Animal studies indicate protective effects occur at non-toxic doses with demonstrated antigenotoxic properties. However, comprehensive human safety data is absent, including effects during pregnan |
