A

Benfotiamine

Supplements

Mechanism

Lipid-soluble thiamine derivative that improves cellular thiamine availability and helps reduce advanced glycation stress in high-glucose environments.

Contraindications

  • None established at standard doses
B

Berberine

Supplements

Mechanism

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.

Standard Dosing

500mg 2-3x daily (1000-1500mg total)

Timing

With meals or immediately before meals (reduces postprandial glucose spike). Must be taken with food.

Cycle Duration

Cycle 8-12 weeks on, 4 weeks off (or continuous under practitioner supervision)

Side Effects

  • GI cramping/diarrhea (dose-dependent)
  • Constipation in some
  • Abdominal distension
  • Potential for hypoglycemia

Contraindications

  • Pregnancy (uterotonic — may induce contractions)
  • Lactation
  • Concurrent use of multiple CYP3A4 metabolized drugs
  • Severe liver disease
