Why Berberine matters for longevity
A plant alkaloid with metformin-like effects on glucose handling and lipid metabolism, useful for metabolic optimization without prescription access.
- Fasting glucose and HbA1c reduction comparable to metformin in T2D trials
- Lower LDL and triglycerides
- Improved insulin sensitivity
- Favorable gut microbiome shifts
Typical dose
500 mg three times daily with meals
Best timing
Immediately before or with each main meal
