Older Adults
Studies show that to 30 percent of all adults 50 years and up may have atrophic gastritis, an increased growth of intestinal bacteria, and be unable to normally absorb vitamin B12 from food. They are, however, able to absorb the B12 added to fortified foods and dietary supplements. Studies suggest that vitamin supplements may be the best sources of vitamin B12 for adults older than age 50 years and up.
Researchers Have Long Studied The Connection Between B12 Deficiency and Dementia In Older Adults.
Recently studies between cognitive skills, homocysteine levels, and blood levels of foliate, vitamin B12 and vitamin B6 suggest that that vitamin B12 deficiency may decrease levels of substances needed for the metabolism of neurotransmitters. In individuals at risk for dementia, researchers found that a daily supplement providing 2 milligrams (mg) folic acid and 1 mg vitamin B12, taken for 12 weeks, lowered homocysteine levels by 30%. They also demonstrated that cognitive impairment was significantly associated with elevated plasma total homocysteine.
Vegetarians
The popularity of vegetarian diets has risen in recent years. The term vegetarianism has a wide range of definitions. Many consider themselves to be vegetarian because they do not eat red meat. But many believe that vegetarianism requires avoidance of all animal products including eggs and dairy products.
Strict Vegetarians & Vegans Are At A Greater Risk Of Deficiency.
Strict vegetarians and vegans who do not eat foods that come from animals need to highly consider dietary supplements that contain vitamin B12 and should discuss the need for vitamin B12 supplements with their physician.
Infants Deficient In B12 Can Cause Permanent Brain Damage. Consequences of such neurological damage are severe and can be irreversible. There are many case reports in the literature of infants and children who suffered consequences of vitamin B12 deficiency. It is very important for mothers who are strict vegetarians to meet with a pediatrician regarding appropriate use of vitamin B12 supplements for their infants and children.
