Dihydroberberine (DHB) is a hydrogenated derivative of berberine, a natural alkaloid from Berberis and Coptis species. DHB is naturally present in small amounts in Phellodendri Chinese Cortex. It is converted to berberine in the body but achieves much higher plasma concentrations at equivalent oral doses.
DHB is absorbed more efficiently than berberine and is oxidized back to berberine after entering the bloodstream. Like berberine, it inhibits mitochondrial respiratory complex I (similar to metformin), activates AMPK, and improves insulin sensitivity. DHB also targets glucokinase (GCK) in pancreatic β-cells, promoting glucose-stimulated insulin secretion. Additionally, it modulates NF-κB and MAPK signaling to reduce inflammatory cytokine production.
Adults with prediabetes, type 2 diabetes, or metabolic syndrome seeking better-tolerated berberine alternative. Those who experience GI side effects from standard berberine may tolerate DHB better.
Avoid in pregnancy and breastfeeding. Use caution with CYP3A4 substrates (berberine inhibits CYP3A4). Those on hypoglycemic medications should monitor blood glucose closely. Not for type 1 diabetes.

Each bar = one cited trial. Effect varies by methodology, dose, and population.
Pre-diabetic cohort (n≈80)
Target HbA1c <6.5% for pre-diabetes management.
L6 myotubes + rodent model
→ DHB inhibited complex I like metformin and rosiglitazone, activated AMPK independent of LKB1/CAMKK, and showed improved in vivo efficacy in countering adiposity and insulin resistance in high-fat-fed rodents
Human pilot trial
→ DHB 100 mg produced significantly greater plasma berberine AUC (284.4 ng/mL×120 min) compared to 500 mg standard berberine (42.3 ng/mL×120 min), confirming ~5–8× superior bioavailability
MIN6 and INS-1 cells + mice
→ DHB promoted glucose-stimulated insulin secretion by forming compact complexes with glucokinase (GCK). Effects were abolished by GCK siRNA knockdown, confirming GCK as the target
B · Human pharmacokinetic trial confirms 5–8× superior bioavailability over berberine. Mechanistic studies validate AMPK activation and novel GCK targeting. Large-scale glucose outcome RCTs specific to DHB are still needed

Who benefits most
Adults with prediabetes, type 2 diabetes, or metabolic syndrome seeking better-tolerated berberine alternative. Those who experience GI side effects from standard berberine may tolerate DHB better.
Dosage and form
100 mg is the typical effective range. Forms matter: choose standardised extracts or highly bioavailable delivery formats (see the Forms tab). Take as directed.
Side effects and cautions
Better tolerated than berberine. Rare mild GI in first week. Avoid if you: Avoid in pregnancy and breastfeeding. Use caution with CYP3A4 substrates (berberine inhibits CYP3A4). Those on hypoglycemic medications should monitor blood glucose closely. Not for type 1 diabetes..
The evidence
Human clinical trials and mechanistic research support the use of Dihydroberberine for its primary indication. See the Research tab for full citations and study summaries.
