🚨 Insulin resistance isn’t about making too little insulin—it’s about your cells not letting it in. When key intracellular vitamins are missing, your insulin receptors can’t work properly—think of it like broken parts on an engine. Fix the deficiencies early and you can often reverse type 2 diabetes before it’s permanent. Band-aid meds like metformin can keep you going, but they won’t fix the root cause.
