| **Category** | Enzyme | Fruit |
| **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 | Chrysophyllum albidum, Agbalumo, White star apple |
| **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. | 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-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 | 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** | No direct supplementation; modulation through lifestyle and dietary choices. 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.

| **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  | 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 |

## 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.
