Description
Benefits
- Supports insulin sensitivity and glucose regulation
- Helps stabilize post-meal glucose and insulin levels
- XR formulation provides smoother, sustained activity
- Often better tolerated gastrointestinally than immediate-release metformin
- Commonly used during bulking, recomposition, or metabolic reset phases
- Frequently incorporated into longevity-focused metabolic protocols
Background and History
- Metformin has been used for decades as a first-line metabolic therapy
- Improving insulin sensitivity is central to reducing cardiometabolic risk
- Chronic metabolic stress is increasingly linked to accelerated aging
- Extended-release formulations were developed to improve tolerability and adherence
- Research connected metformin’s metabolic effects to mitochondrial and cellular pathways
- These findings drove adoption in both performance optimization and longevity medicine
