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.

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.
