Does berberine lower bad cholesterol?

The claim, precisely: berberine decreases LDL cholesterol

Strong support Supplements
RefutedContestedStrong support
consensus score 0.82

Yes, by about 20-25%, well-supported by pooled human trials, working through a different route than statins.

What the evidence shows

Berberine lowers LDL (~20-25%) via a statin-distinct mechanism (stabilizing LDL-receptor mRNA), confirmed mechanistically and in meta-analyses of RCTs. A genuine, independent finding Norwitz promotes - well-supported, and unrelated to his LDL-skepticism.
