Berberine activates AMP-activated protein kinase (AMPK), the master metabolic sensor, mimicking many effects of caloric restriction and exercise. It inhibits mitochondrial Complex I, increasing the AMP:ATP ratio which triggers AMPK. Downstream effects include enhanced GLUT4 translocation (glucose uptake), inhibition of HMG-CoA reductase (cholesterol synthesis), upregulation of LDL receptor expression, and suppression of PCSK9. It also modulates gut microbiome composition, increasing short-chain fatty acid-producing bacteria.

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.
