Is dihydroberberine the same as berberine?

Dihydroberberine is a reduced form of berberine. After intestinal absorption it converts back to berberine, delivering the same active compound via a pathway with approximately 5x higher bioavailability.

How much dihydroberberine is equivalent to 500 mg berberine?

Research suggests 100–200 mg of dihydroberberine may deliver similar active berberine exposure to 500–1,000 mg of standard HCl, though individual response varies.

Can dihydroberberine cause GI side effects?

At typical doses (100–300 mg), dihydroberberine is associated with significantly fewer GI complaints than high-dose standard berberine HCl protocols.
