| **Evidence Score** | 8/10 | 8/10 |
| **Category** | Compound | Other |
| **Also Known As** | 5-hydroxytryptophan, 5-HTP, L-5-hydroxytryptophan, oxitriptan, Griffonia extract, 5-hydroxy-L-tryptophan, serotonin precursor | 2-[(diphenylmethyl)sulfinyl]acetamide, CRL-40028, Olmifon, diphenylmethylsulfinylacetamide, benzhydrylsulfinylacetamide |
| **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. | Adrafinil is a synthetic eugeroic compound that promotes wakefulness by converting to modafinil in the liver via hydrolysis. It enhances alertness and cognitive function by increasing dopamine, norepinephrine, and orexin levels in the brain. |
| **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 | Adrafinil acts as a prodrug that undergoes hepatic hydrolysis to form modafinil, the active metabolite. Modafinil then inhibits dopamine reuptake transporters (DAT) and blocks GABA release, while simultaneously increasing orexin/hypocretin neurotransmission in the hypothalamus. This dual mechanism e |
| **Dosage** | Commonly taken in doses of 50-300 mg per day, divided into multiple doses. Consult a healthcare provider before use. | Typical dosage ranges from 300-600 mg per day. Available in capsules and tablets. 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 | Adrafinil may cause elevated liver enzymes due to hepatic metabolism, requiring periodic liver function monitoring with prolonged use. Common side effects include headache, nausea, anxiety, and insomnia, typically dose-dependent. It can interact with hormonal contraceptives by inducing CYP3A4 enzyme |

## Adrafinil — Full Health Benefits

- Promotes wakefulness by increasing orexin levels, which enhances alertness and reduces fatigue. This effect is beneficial for those needing sustained focus. - Enhances cognitive function by boosting dopamine and norepinephrine, leading to improved mental clarity and memory retention. This is particularly useful for students and professionals. - Improves mood by modulating serotonin levels, which can help alleviate symptoms of depression. This makes it a potential aid for emotional well-being. - Increases energy levels by enhancing ATP production in the brain, which supports prolonged mental and physical activity. This is ideal for athletes and busy individuals. - Supports neuroprotection by reducing oxidative stress, which helps preserve brain health over time. This is crucial for long-term cognitive function. - Enhances learning capacity by facilitating synaptic plasticity, which is the brain's ability to adapt and learn new information. This is beneficial for lifelong learners. - Reduces reaction time by optimizing neurotransmitter activity, which can improve performance in tasks requiring quick decision-making.
