(ORDO NEWS) — Vitamin B12 deficiency can cause severe damage to the nervous system, including dementia. This process can also increase the risk of cardiovascular disease.
Vitamin B12 deficiency is more common in older people between the ages of 65 and 74, according to the National Health Service of England.
She notes that vitamin B12 helps maintain the health of nerve cells and red blood cells, and its deficiency can cause various diseases, including memory loss.
The Mayo Clinic says some research suggests that low vitamin B12 levels may be associated with an increased risk of dementia, but “ B vitamin supplementation has not been shown to improve brain function or symptoms of memory loss,” the clinic said.
According to this medical institution, the recommended daily allowance for vitamin B12 for adults is 2.4 micrograms.
That being said, people on a vegetarian or vegan diet may be prone to deficiency because plant foods do not contain vitamin B12, the doctors explain.
Good sources of vitamin B12 are meat, fish, milk, cheese, and eggs. Sometimes vegan and vegetarian foods are separately fortified with vitamin B12, such as some plant-based dairy products or breakfast cereals.
