A Mental Sign Of Vitamin B12 Deficiency

A Mental Sign Of Vitamin B12 Deficiency post image

Around 12.5 percent of people over 50 have a vitamin B12 deficiency.

Recent research finds that around 12.5 percent of people over 50 have a vitamin B12 deficiency.

Having problems with general thinking and memory skills can indicate vitamin B12 deficiency.

People with a vitamin B12 deficiency can have problems with worse memory for events and ideas.

Other, more common signs of vitamin B12 deficiency include feeling tired, experiencing muscle weakness and being constipated.

Brain shrinkage has even been linked to vitamin B12 deficiency.

The result come from a study of 5,290 people in Ireland.

The study found that along with B12 deficiency, 14 percent had a folate deficiency.

Very few people in the study took supplements to correct the deficiency.

Vitamin B12 and folate are both vital for nerve function, brain health and DNA.

Fortunately, these deficiencies are easy to rectify with diet or supplementation.

Good dietary sources of vitamin B12 include fish, poultry, eggs and low-fat milk.

Fortified breakfast cereals also contain vitamin B12.

Professor Anne Molloy, study co-author, said:

“This study shows a surprising level of inadequate folate among older persons, despite many years of voluntary folic acid fortification of certain foods on the Irish market.

Concerns relating to excessive folic acid intake, particularly in older people, have been at the heart of current debates regarding the risks of population-wide folic acid fortification.”

The rate of vitamin B12 deficiency is higher in those who are older, vegetarian, smokers or have certain digestive problems, such as Crohn’s disease.

Vitamin B12 deficiency has also been linked to depression.

Typical symptoms of depression include low mood, loss of energy and problems concentrating.

In fact, people with a deficiency in vitamin B12 are at triple the risk of developing melancholic depression, one study has found.
