| **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 | Chrysophyllum albidum, Agbalumo, White star apple |
| **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. | African star apple (Chrysophyllum albidum) contains bioactive phenolic compounds—including beta-amyrin acetate, epicatechin, and epigallocatechin—that inhibit α-glucosidase and α-amylase enzymes in a dose-dependent manner, with its pulp coat demonstrating potent α-amylase inhibition (IC₅₀ of approxi |
| **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 | African star apple exerts its biological effects primarily through dual enzymatic inhibition: its phenolic compounds—beta-amyrin acetate, epicatechin, and epigallocatechin—competitively bind the active sites of α-glucosidase and α-amylase, slowing the hydrolysis of complex carbohydrates into absorba |
| **Dosage** | Commonly taken in doses of 50-300 mg per day, divided into multiple doses. Consult a healthcare provider before use. | - Common Forms: Fresh fruit, juice, roasted seeds, extracts.
- Traditional Use: Eaten fresh, juiced, or incorporated into desserts; roasted seeds consumed as snacks.
- Modern Applications: Used in smoothies, functional beverages, dietary supplements, and skincare products.
- Recommended Dosage: 1/4– |
| **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 | African star apple is widely consumed as a traditional fruit across West and Central Africa and is generally regarded as safe when eaten as part of a normal diet. Due to its demonstrated α-amylase and α-glucosidase inhibitory activity, individuals taking antidiabetic medications such as metformin or |
