4. Anxiety and lowered mood
It is a well-known fact that B12 is essential for the proper functioning of the central nervous system, so its deficiency can have a strong impact on mental health. People who are deficient in this nutrient are at a greater risk of developing depression and anxiety.
But how does it work? Low levels of B12 in the body prevent an amino acid called homocysteine from breaking down, which increases the risk of DNA damage and cell death.
5. Difficulty with focus and concentration
Older people are more likely to experience this symptom, as the risk of B12 deficiency increases with age. If you`ve recently noticed that it is hard for you to concentrate and complete tasks, this may also be a sign of this deficiency. The good news is that such mental impairments improve as soon as B12 levels return to normal.
