Pterostilbene vs Serrapeptase

Mechanism

Dimethylated analog of resveratrol with 4x greater oral bioavailability. Activates SIRT1 and AMPK, reduces oxidative stress, and improves lipid profiles. Superior pharmacokinetics compared to resveratrol due to methyl groups protecting against glucuronidation.

Contraindications

• Hormone-sensitive conditions (mild estrogenic activity)

Mechanism

Serrapeptase (serratiopeptidase) is a proteolytic enzyme originally isolated from the gut of the silkworm (Serratia marcescens). It hydrolyzes non-living tissue including fibrin, blood clots, cysts, and arterial plaque while sparing living tissue. It reduces bradykinin and other pain-mediating amines, provides anti-inflammatory effects by reducing neutrophil infiltration, and thins mucus by cleaving glycoprotein structures. It may also enhance antibiotic penetration into biofilms.

Standard Dosing

120,000-240,000 SPU (serratiopeptidase units) daily

Timing

On empty stomach (critical — food proteins will be digested instead of systemic absorption). 30+ minutes before meals or 2 hours after.

Cycle Duration

Cycle 4-8 weeks on, 2-4 weeks off

Side Effects

• GI discomfort
• Nausea
• Skin rash (rare)
• Muscle/joint pain (rare)
• Pneumonitis (very rare, case reports)

Contraindications

• Bleeding disorders
• Scheduled surgery (discontinue 2 weeks prior)
• Concurrent anticoagulant therapy
• Active peptic ulcers
• Active bleeding
• Pre-surgery
• Blood clotting disorders
