Berberine HCl (sustained release)
What it is
Sustained-release berberine reduces the GI side effects (cramping, diarrhoea) common with standard berberine. Early studies suggest similar blood sugar lowering with fewer gut complaints. Most clinical evidence still comes from the standard form. SR formulations are newer, more expensive, and have fewer independent trials. A reasonable option for those who cannot tolerate regular berberine.
Dose
500–1,000 mg/day sustained-release berberine HCl; fewer GI side effects than standard form
Time of day & tips
Take once daily with breakfast. The sustained-release form maintains 24-hour coverage from a single dose, unlike standard berberine which needs 3× daily. Do not combine with metformin or cyclosporine without medical guidance.
