How this estimate works
Blood sugar goal: 1,500 mg/day as three 500 mg doses with meals. Lipid goal: 1,000 mg/day as two 500 mg doses with meals. The range shown reflects common trial totals; amounts above 1,500 mg/day need clinician oversight.

Frequently asked questions
Is berberine dose based on body weight?
No. The common trial amounts shown here are fixed daily totals, not weight-based doses.
Can I combine berberine with diabetes medicine?
Berberine may add to glucose lowering and can interact with medicines. Talk with your prescriber before combining it with metformin, insulin or a sulfonylurea.
How long should I wait before checking results?
This calculator suggests discussing a repeat HbA1c or lipid test at about 12 weeks. Your clinician may recommend a different interval.
