Berberine

mg/day

A plant alkaloid, usually about 500 mg of berberine hydrochloride three times a day. Trials treat that salt as its own dose.

Trials often use about 1.0 to 1.5 g a day for three to five months in people with metabolic syndrome or type 2 diabetes. A multivitamin, a drink that adds hops, or a protocol paper with no result is not this exposure.

Also called berberine hydrochloride, Berberis.

MECHANISM− DECREASES

Randomized trial · Contested

Berberine→Insulin resistance (HOMA-IR)

Higher Berberine decreases Insulin resistance (HOMA-IR).

Perez-Rubio 2014 found that 500 mg of berberine three times a day for three months raised the Matsuda insulin-sensitivity index from 2.1 to 3.1 versus placebo in 24 people with metabolic syndrome. Zhang 2008 lowered glucose versus placebo in 116 people with type 2 diabetes; the clamp contrast missed.
