Citrus Bergamot Extract vs Saw Palmetto (Serenoa repens)

Mechanism

Contains brutieridin and melitidin — statin-like HMG-CoA reductase inhibitors from bergamot orange. Activates AMPK, improves lipid profiles (reduces LDL, increases HDL), and has antioxidant effects. Supports cardiovascular and metabolic health.

Contraindications

• Rhabdomyolysis risk if combined with high-dose statins without monitoring

Mechanism

Saw palmetto berry extract contains fatty acids (lauric acid, oleic acid, myristic acid) and phytosterols (beta-sitosterol) that inhibit both isoforms of 5-alpha-reductase (types I and II), reducing conversion of testosterone to dihydrotestosterone (DHT). It also exhibits anti-androgenic activity by competing with DHT at androgen receptor binding sites. Additional mechanisms include: inhibition of cyclooxygenase and 5-lipoxygenase (anti-inflammatory in prostate tissue), induction of apoptosis in prostate epithelial cells, and relaxation of bladder smooth muscle via alpha-1 adrenergic receptor antagonism.

Standard Dosing

320mg daily (standardized to 85-95% fatty acids and sterols)

Timing

With food (fat-soluble lipophilic extract). Morning or evening.

Cycle Duration

Minimum 3 months to assess response; ongoing for maintenance

Side Effects

• Mild GI discomfort
• Headache
• Dizziness
• Rare: erectile dysfunction (DHT reduction)
• Rare: liver injury (case reports)

Contraindications

• Pregnancy (anti-androgenic — teratogenic potential for male fetus)
• Hormone-sensitive conditions (complex hormone modulation)
• Children
