Metformin vs. Berberine Phytosome: Understanding the Differences

Both metformin and berberine are used to improve insulin sensitivity.

But they are not identical.

At Sheen Vein in St. Louis, Clayton, Chesterfield, Arnold, and Farmington, we discuss both options depending on the patient’s goals and medical profile.

What Is Metformin?

4

Metformin is a prescription medication that:

• Reduces hepatic glucose production
• Improves insulin sensitivity
• Activates AMPK

It has decades of data behind it.

What Is Berberine Phytosome?

Berberine is a plant alkaloid found in:

• Berberis
• Goldenseal
• Coptis

Standard berberine has low absorption.

Berberine phytosome improves bioavailability significantly.

Mechanistically, berberine also activates AMPK — similar to metformin.

Key Differences

Feature: Metformin / Berberine Phytosome

Prescription: Yes / No

GI side effects: Common / Less common

Long-term data: Extensive / Growing

Clinical Considerations

We consider:

• A1C
• Fasting insulin
• GI tolerance
• Liver health
• Patient preference

Some patients in Chesterfield and Clayton prefer a natural compound when appropriate.

Others benefit from pharmaceutical precision.

Our Philosophy

The question is not “natural vs pharmaceutical.”

The question is:

What is safest and most effective for this specific patient?
