Your bloodwork came back "normal," but your feet still burn — so what gives? In this 5-minute breakdown, Dr. Fitz explains why a "normal" B12 result can be misleading, and why the 2.4 mcg daily requirement on the label was set to prevent anemia, not to support nerve health. He covers the gap between that number and the 2,000 mcg amounts often used for nerve support, why the form of B12 matters as much as the dose, and why a standard serum test may not reflect what's actually reaching your nerves.
