Assessment Explanation
The claim specifies a quantitative range (10–15%, 10–20%) and is based on human studies, which are feasible with randomized controlled trials. However, the lack of dosage or duration details makes it imprecise. The verb 'reduces' implies a direct causal effect, but existing evidence shows variability across studies due to differences in formulation, dose, and population. A probabilistic verb like 'may reduce' better reflects the current evidence. The range is plausible based on meta-analyses, but not universally consistent.
More Accurate Statement
“Oral berberine supplementation may reduce circulating LDL cholesterol by 10–15% and triglycerides by 10–20% in some humans, based on limited clinical trials with variable dosing and duration.”

Evidence from Studies

Berberine is a novel cholesterol-lowering drug working through a unique mechanism distinct from statins
This study gave people berberine pills and found their bad cholesterol and fat levels dropped even more than the claim said they would — so yes, berberine works as described.
