Dihydroberberine is a reduced form of berberine, a bioactive compound found in several plants, and is often categorized alongside amino acids and related bioactive compounds in the supplement space. Research suggests that dihydroberberine may support healthy blood sugar metabolism, with studies indicating it has significantly greater intestinal absorption than standard berberine, potentially allowing lower amounts to achieve similar effects. The patented form known as GlucoVantage has been the subject of growing interest for its role in supporting glucose regulation and insulin sensitivity. While preliminary findings are encouraging, much of the research builds on the broader berberine literature, and more human clinical trials specifically on dihydroberberine are needed to fully understand its long-term effects and optimal applications.

| Form | Dose range | Frequency | Studied for | Source |
|---|---|---|---|---|
| Capsule | 100–200 mg | Twice daily | blood sugar regulation | Used in clinical trials comparing dihydroberberine to berberine; lower doses studied due to enhanced bioavailability |
| Capsule | 200–400 mg | Daily | blood sugar regulation and insulin sensitivity | Common range in human pilot studies; dihydroberberine considered roughly 2x more bioavailable than berberine |
| Capsule | 105 mg | Twice daily | postprandial blood glucose control | Specific dose used in a published RCT (Yap et al.) evaluating GlucoVantage dihydroberberine vs. berberine |
