| **Evidence Score** | 8/10 | 8/10 |
| **Category** | Enzyme | Other |
| **Also Known As** | 5α-reductase, Steroid 5α-reductase, 3-oxo-5α-steroid 4-dehydrogenase, DHT synthase, Testosterone 5α-reductase, 5AR, Type I and Type II 5α-reductase | 2-[(diphenylmethyl)sulfinyl]acetamide, CRL-40028, Olmifon, diphenylmethylsulfinylacetamide, benzhydrylsulfinylacetamide |
| **Overview** | 5-alpha reductase is an enzyme that converts testosterone to dihydrotestosterone (DHT), playing a crucial role in androgen metabolism. Inhibiting this enzyme helps reduce DHT levels, supporting prostate health and potentially slowing male pattern hair loss. | 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-alpha reductase catalyzes the conversion of testosterone to dihydrotestosterone (DHT) using NADPH as a cofactor. The enzyme exists in two isoforms: Type I (primarily in skin and liver) and Type II (concentrated in prostate tissue). DHT binds to androgen receptors with 3-5 times greater affinity th | 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** | No direct supplementation; modulation through lifestyle and dietary choices. 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 decreased libido (3-5%), erectile dysfunction (2-4%), and reduced ejaculatory volume (1-3%). Post-finasteride syndrome, characterized by persistent sexual and neurological symptoms, affects approximately 1-2% of users even after discontinuation. The enzyme inhibitors may  | 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 |

## 5-Alpha Reductase — Full Health Benefits

- Regulates androgen levels by converting testosterone to dihydrotestosterone (DHT), which helps maintain hormonal balance. - Supports prostate health by reducing DHT accumulation, lowering the risk of benign prostatic hyperplasia (BPH) by up to 35% in clinical studies. - Influences hair growth and scalp health by modulating DHT, a key factor in male and female pattern hair loss. - Enhances skin health by balancing sebum production, reducing acne flare-ups linked to excess androgens. - Promotes reproductive health by ensuring optimal androgen activity, which is essential for libido and fertility. - May support cardiovascular wellness by influencing androgen-mediated lipid metabolism. - Helps maintain muscle mass and bone density by regulating androgenic effects on tissues. - Modulates mood and cognitive function through its impact on neurosteroids derived from androgen metabolism.

## 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.
