Metformin has become one of the most talked-about medications in longevity and anti-aging medicine. 

In this 15-minute course, Dr. Stephen Petteruti breaks down what metformin actually does inside your cells, how it influences inflammation, blood sugar, AMPK activation, and autophagy, and why it appears to reduce the long-term risk of chronic diseases—especially in people with metabolic challenges.

You will learn how metformin affects blood sugar stability, endothelial function, cellular recycling, and the pathways linked to aging.

This course explains who benefits most from metformin, who may not need it, how to interpret your hemoglobin A1c, and what the research suggests about longevity, cancer risk, diabetes, and metabolic health.

You’ll also hear about common side effects, medication interactions, and how metformin compares to natural alternatives such as berberine.

If you are exploring metformin for anti-aging, metabolic support, inflammation reduction, or long-term disease prevention, this quick, direct lesson gives you a clear framework to help you make an informed decision.
