|---|---|---|
| **Evidence Score** | 8/10 | 8/10 |
| **Category** | Compound | Fruit |
| **Also Known As** | 5-hydroxytryptophan, 5-HTP, L-5-hydroxytryptophan, oxitriptan, Griffonia extract, 5-hydroxy-L-tryptophan, serotonin precursor | Malpighia emarginata, Barbados cherry, West Indian cherry, Puerto Rican cherry, Wild crepe myrtle, Cereja-de-barbados, Acerola cherry |
| **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. | Acerola contains 17% natural vitamin C (ascorbic acid) plus bioflavonoids that enhance absorption and bioavailability. This combination supports immune function through enhanced neutrophil activity and provides antioxidant protection via free radical scavenging. |
| **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 | Acerola's ascorbic acid stimulates neutrophil chemotaxis and enhances interferon production, while co-occurring anthocyanins and quercetin amplify antioxidant capacity. The vitamin C promotes collagen synthesis by serving as a cofactor for prolyl 4-hydroxylase and lysyl hydroxylase enzymes. Bioflavo |
| **Dosage** | Commonly taken in doses of 50-300 mg per day, divided into multiple doses. Consult a healthcare provider before use. | Take 500-1000 mg of acerola extract daily. Consult a healthcare provider before use. |
| **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 | Acerola is generally well-tolerated with side effects limited to mild gastrointestinal upset at doses above 2000mg daily. High vitamin C intake may reduce effectiveness of warfarin and chemotherapy drugs like bortezomib. Individuals with glucose-6-phosphate dehydrogenase deficiency should avoid high |
