moderate · Named by an FDA label or NIH page · Blood sugar lowering
In the source’s own words; rated moderate from that wording, not from a study of the pair.

Minor
3BerberineStudiedBerberine adds a second glucose-lowering effect
minor · Studied in people (PubMed) · evidence B · Blood sugar lowering
Two glucose-lowering agents together. The trials were small and of low methodological quality, and reported no serious side effects from berberine.
To raise with your pharmacist or prescriberTell your prescriber before adding berberine, especially if you also take insulin or a sulfonylurea, where low blood sugar is a bigger concern (inferred).

How these lines are sourced
Three kinds of line
- Studied in people (PubMed): PubMed records that were opened and read, graded A (several controlled studies, or a finding in the dosing guidance), B (at least one controlled human study) or C (case reports, observational data or mechanism only).
- Named by an FDA label or NIH page: quoted word for word from that page. Its severity comes from the source’s wording, not from a study of the pair.
- Predicted from how each works, not established: built from sourced facts about each substance, such as the FDA’s table of enzyme roles. Never rated major.
