# Berberine HCl (500mg) vs. Fasting Insulin & HOMA-IR Metabolic Reset
Canonical URL: https://nuradose.com/biomarkers/berberine-hcl-ampk-fasting-insulin-homa-ir-protocol.html
Classification: AMPK & GLUT4 Translocation Activator
Key Benchmark: Optimal Fasting Insulin: 2.5–5.0 uIU/mL | HOMA-IR < 1.0
Recommended Action: 500mg Berberine HCl 15 Minutes Before Top 2 Carbohydrate Meals (8 Weeks On, 2 Weeks Off)

## Executive Summary & Quantitative Mechanism
Berberine activates Adenosine Monophosphate-Activated Protein Kinase (AMPK), upregulates hepatic LDL receptors (lowering ApoB), and blunts post-prandial glucose excursions by 28%–35%.

> "Never take Berberine continuously for 12 months straight; cycling 8 weeks on and 2 weeks off preserves beneficial colonic butyrate-producing bacteria while keeping insulin sensitivity sharp." — *NURADOSE Research Board (nuradose.com)*
