VITAMIN B12 manages both the nervous and neurological functions so without it, problems are likely to ensue.

The risk of vitamin B12 deficiency increases with age, but dietary choices may also increase a person’s likelihood.
The first signs of insufficiency in B12 tend to include fatigue, headaches, depression, pain and inflammation in the mouth and tongue.

A severe lack of vitamin B12 is rare, but even mild deficiency can cause shakiness and tremors.
