Nattokinase

Supplements

Mechanism

Nattokinase is a fibrinolytic serine protease extracted from natto (fermented soybeans). It directly degrades fibrin (the structural protein of blood clots) through four mechanisms: direct fibrinolysis, enhancement of endogenous tPA (tissue plasminogen activator) production, conversion of prourokinase to urokinase, and degradation of PAI-1 (plasminogen activator inhibitor-1). It also reduces blood viscosity and may inhibit ACE (angiotensin-converting enzyme), providing mild antihypertensive effects.

Standard Dosing

2000-4000 FU (fibrinolytic units) daily, equivalent to 100-200mg

Timing

On empty stomach, between meals or before bed. Morning and evening split dosing for 24-hour fibrinolytic coverage.

Cycle Duration

Resveratrol

Supplements

Mechanism

Resveratrol activates SIRT1 (the longevity sirtuin) via allosteric binding, promoting deacetylation of PGC-1alpha (mitochondrial biogenesis), FOXO3 (stress resistance), and p53 (DNA repair). It inhibits NF-kB and COX-2, reducing chronic inflammation. Resveratrol also activates AMPK independently of SIRT1 and inhibits phosphodiesterases (PDEs), raising cAMP levels. It improves endothelial function via eNOS upregulation and NO production.

Standard Dosing

250-500mg trans-resveratrol daily

Timing

Morning with a fat-containing meal. Often taken alongside NMN for synergistic sirtuin activation.

Cycle Duration

ongoing

Side Effects

  • GI upset/diarrhea at high doses
  • Headache
  • Joint pain (rare)
  • Insomnia (if taken late)

Contraindications

  • Estrogen-sensitive cancers (theoretical ER agonism)
  • Bleeding disorders
  • Pregnancy/lactation
