Berberine administration (0.2–10 g/day) significantly reduces oxidative stress and inflammation in Type 2 Diabetes Mellitus (T2DM) patients and animal models, leading to improved insulin sensitivity and glycemic control comparable to metformin.

If you have Type 2 Diabetes, berberine is a botanical supplement shown to lower blood glucose by 20-40%, performing similarly to standard drugs like metformin. It works by reducing inflammation and oxidative stress, which improves insulin sensitivity. Clinical studies used doses between 0.2g and 1g daily. It may be particularly useful for patients who also have liver issues, as berberine appears to protect hepatic function while lowering sugar.

ModerateSupportsMEDIUM confidence
Berberine is a biologically active botanical that can combat oxidative stress and inflammation and thus ameliorate DM, especially type 2 DM... The treatment efficacy of berberine has been found comparable with the reference antidiabetic drugs such as metformin... Various clinical studies have described the safety and effectiveness of berberine (at a dose of 0.2–10 g/day) in treating T2DM patients. Generally, a decrease in blood glucose level by 20–40% is reported in fasting patients treated with berberine alone, this effect resembles to that of rosiglitazone and metformin

Why this rating

The paper is a review citing multiple animal and some human studies, but notes the need for large-scale, high-quality, long-term randomized clinical trials.
