  "body": "## What's breaking down\n\nChronic metformin use targets metabolic pathways to lower blood glucose but can affect nutrient absorption and cellular energy over time. One clear layer is vitamin B12 status. Multiple human studies link long-term metformin to reduced B12 levels through interference with calcium-dependent absorption in the ileum and possible changes in gut motility or bacterial balance. Prevalence of deficiency ranges from 5% to 40% depending on dose, duration, and population. Low B12 can impair nerve function and red blood cell production.\n\nA second layer involves mitochondrial function. Metformin accumulates in mitochondria and inhibits complex I of the electron transport chain. This reduces ATP production, which helps suppress liver glucose output but may alter energy balance in other tissues during extended use. These effects are context-dependent and tied to the drug's primary role as a metabolic regulator rather than a direct repair agent.\n\nNo specific degenerative condition like disc height loss or joint breakdown is tied to the query. The focus stays on metabolic and nutrient layers that arise from ongoing metformin therapy.\n\n## Why Metformin matters for you\n\n1. **Drug:** Metformin\n2. **What it does:** Metabolic tool that lowers hepatic glucose product
