Dihydroberberine Capsules

Berberine has strong research behind it. A review of 14 clinical studies found it may be as effective as certain oral diabetes drugs for supporting healthy blood sugar levels [1]. A separate study of 116 people found that 1g of berberine daily lowered fasting blood sugar by 20% and HbA1c by 12% [2]. The problem? Your body barely absorbs it. Standard berberine has poor oral bioavailability, and at the doses needed to be effective (900-2,000mg/day), stomach cramping and diarrhea are common complaints.

Dihydroberberine is the form your body converts berberine into during digestion. By taking it directly, you skip that bottleneck. In a 2021 randomized, controlled human trial, 100mg of dihydroberberine produced significantly higher plasma berberine levels than 500mg of standard berberine over a two-hour window [3]. That's up to 5x more absorption per milligram.

The original 2008 study that identified dihydroberberine, published in Diabetes, found that it activates AMPK, the same metabolic pathway targeted by metformin, with improved oral bioavailability compared to regular berberine. In high-fat-diet animal models, it reduced adiposity and tissue triglyceride accumulation [4]. A 2026 study went further, showing that dihydroberberine also targets glucokinase, an enzyme involved in insulin secretion in pancreatic cells [5].

At 250mg per capsule, you're getting a research-backed dose without the GI issues that make standard berberine hard to stick with.
