What Researchers Say

Peter Attia
Peter Attia Agrees

Uses for LDL management via PCSK9 inhibition. Prefers metformin for glucose. Recommends Thorne brand.

Andrew Huberman
Andrew Huberman Nuanced

Personally avoids berberine, metformin, and rapamycin - insufficient human data for longevity.

Mark Hyman
Mark Hyman Agrees

Positive as AMPK activator and herbal antimicrobial for gut health.

Detailed Answer

Berberine safety depends on use case. Attia uses it clinically as a weak PCSK9 inhibitor for LDL management, preferring Thorne brand. He calls it a "weak AMPK activator" and prefers pharmaceutical metformin for glucose control.

Huberman explicitly avoids berberine for longevity, citing insufficient human data and hypoglycemia risk. Hyman views it positively for AMPK activation and as an antimicrobial for gut dysbiosis.

Key risks: potent blood sugar lowering (hypoglycemia), GI side effects, CYP3A4/CYP2D6 drug interactions, and no pregnancy use. Long-term safety data is limited.
