A person lacking in the vitamin could have symptoms in their hands, feet and eyes.

There is also a symptom in their sleep.

Treatment for a vitamin B12 deficiency

If a person has trouble absorbing vitamin B12, they will need to get shots of the vitamin first.

They may also need to keep getting these shots, take high doses of a supplement by mouth or may need to get an injection.

Older adults who have a vitamin B12 deficiency will likely have to take a daily B12 supplement or a multivitamin that contains B12.

Since your body doesn’t make vitamin B12, you have to get it from animal-based foods or from supplements.

And you should do that on a regular basis, because your body doesn’t store vitamin B12 for a long time. How much vitamin B12 a person should get depends on things including age, eating habits and medical conditions.

The average amount for adults is 2.4 mcg per day and should not be exceeded unless your GP suggests so.
