berberine decreases LDL cholesterol
In plain terms: Does berberine lower bad cholesterol?
Yes, by about 20-25%, well-supported by pooled human trials, working through a different route than statins.

How far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."
Top evidence so far: All trials, pooled (Meta-analysis)
How the studies fall
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.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
