This **Berberine HCl** delivers a full 1,000mg daily dose for blood sugar and metabolic support, landing comfortably within the 500–1,500mg range used in clinical research. That's enough to meaningfully support healthy glucose levels and insulin sensitivity — where berberine has its strongest evidence, backed by multiple meta-analyses.

The catch is timing. The label has you take all three capsules at once, but clinical studies split berberine into 2–3 smaller doses across the day, taken with meals. Berberine clears your body quickly, so spacing it out gives steadier support and eases the digestive discomfort that's common when 1,000mg lands at once.

Worth flagging: berberine interacts with several common medications — metformin and other diabetes drugs, blood thinners, statins, and digoxin. If you take any of these, clear it with your doctor before starting.
