| **Also Known As** | 5-hydroxytryptophan, 5-HTP, L-5-hydroxytryptophan, oxitriptan, Griffonia extract, 5-hydroxy-L-tryptophan, serotonin precursor | Blighia sapida K.D. Koenig, akee, achee, ackee apple, vegetable brain |
| **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. | Ackee fruit (Blighia sapida) contains bioactive phenolic compounds including catechin, epicatechin, and phloridzin that demonstrate antioxidant activity through DPPH and ABTS radical scavenging mechanisms. The ripe arilli are rich in oleic acid and squalene, which increase 12-fold during maturation  |
| **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 | Ackee's phenolic compounds including catechin and epicatechin exert antioxidant effects through free radical scavenging via DPPH and ABTS pathways, with approximately 30% existing in conjugated forms. The high oleic acid content (increasing 12-fold upon ripening) supports cardiovascular health by mo |
| **Dosage** | Commonly taken in doses of 50-300 mg per day, divided into multiple doses. Consult a healthcare provider before use. | - Ackee fruit must be fully ripened and cooked; only the yellow arils are edible, and seeds and inner membranes must be discarded due to toxicity.
- To prepare, boil the arils for 10-15 minutes, then drain and sauté with desired ingredients.

| **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 | Unripe ackee fruit causes Jamaican vomiting sickness, a potentially fatal condition resulting from hypoglycin A toxicity that inhibits fatty acid oxidation and leads to severe hypoglycemia and vomiting. Only fully ripe, naturally opened arilli should be consumed, as hypoglycin A levels remain danger |
