- Nerve Health: B12 is crucial for the production of myelin, the protective sheath around nerves. Without it, nerve signals can slow down or become disrupted.
- Red Blood Cell Production: B12 is necessary for the formation of red blood cells, which transport oxygen throughout the body.
- DNA Synthesis: It plays a role in DNA synthesis, which is vital for cell division and overall health.
