Vitamin
B12 deficiency is often overlooked because its symptoms develop slowly
and can be confused with other health problems. However, if left
untreated, B12 deficiency can lead to more serious health problems. Here
are some signs of vitamin B12 deficiency that are often overlooked:
1. Fatigue and weakness.
Unusual
fatigue or weakness, even after a full night’s sleep, are among the
most common early signs. This occurs because vitamin B12 is essential
for the production of red blood cells, which carry oxygen throughout the
body.
