Taking a special form of berberine called dihydroberberine (100 mg four times a day) gets way more of the active compound into your bloodstream than taking regular berberine pills (500 mg), meaning your body absorbs it much better.

Assessment Explanation
The claim presents precise quantitative data (AUC values) from a controlled human study comparing two interventions. The use of 'significantly higher' implies statistical analysis was performed, and the AUC metric is a standard pharmacokinetic measure. The conclusion that dihydroberberine enhances bioavailability is logically supported by the data presented. No overstatement is evident, as the claim is limited to plasma concentrations over a specific time window and does not extrapolate to clinical outcomes.
More Accurate Statement
“Oral ingestion of 100 mg dihydroberberine four times daily results in a significantly higher area under the plasma concentration-time curve (AUC: 284.4 ng/mL×120 min) over 120 minutes compared to 500 mg berberine hydrochloride (AUC: 42.3 ng/mL×120 min) in healthy young adult males, indicating that dihydroberberine enhances the systemic bioavailability of berberine.”

Absorption Kinetics of Berberine and Dihydroberberine and Their Impact on Glycemia: A Randomized, Controlled, Crossover Pilot Trial
The study found that taking 100 mg of dihydroberberine four times a day led to much higher levels of berberine in the blood than taking 500 mg of regular berberine, which means dihydroberberine gets into the body better.
