Mechanism

Broad-spectrum digestive enzyme complexes supplement endogenous pancreatic and brush border enzyme production. Key enzymes include: lipase (triglyceride hydrolysis to fatty acids/glycerol), protease/peptidase (protein to amino acids via peptide bond cleavage), amylase (starch to maltose/glucose), lactase (lactose to glucose/galactose), cellulase (plant fiber breakdown), and invertase (sucrose hydrolysis). They reduce osmotic load in the small intestine, decrease bacterial fermentation of undigested substrate, and improve nutrient bioavailability.

Standard Dosing

1-2 capsules with each main meal

Timing

Immediately before or at the start of each meal. Not needed for small snacks.

Cycle Duration

ongoing as needed

Side Effects

  • GI cramping if taken without food
  • Allergic reactions (rare)
  • Mouth ulcers from chewing enzyme capsules
  • Perianal irritation from lipase at very high doses

Contraindications

  • Acute pancreatitis
  • Known allergy to enzyme sources (porcine, fungal, fruit-derived)

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

ongoing
