Berberine for Metabolic Syndrome (Cardiovascular Aspects)

B Good Evidence At least one randomized trial supports this, with mostly consistent results.

Improves multiple metabolic parameters: glucose, lipids, BMI, waist circumference. AMPK activation addresses insulin resistance — the core driver of metabolic syndrome.
