Vitamin B12 Deficiency Symptoms That Should Never Be Ignored

B12 supports the myelin sheath, the protective coating around your nerves. When levels drop, that sheath starts to erode, causing nerve damage.

Left untreated, this can progress to balance issues, clumsiness, or even difficulty walking.

So if your limbs feel “asleep” more often than usual — don’t ignore it. Your nerves could be asking for help.
