vitamin b12 as a nutrient that helps keep the body’s nerve and blood cells

helps prevent a type of anemia called megaloblastic anemia that makes people
tired and weak two steps are required for the body to absorb vitamin b12 from
food first hydrochloric acid in the stomach separates vitamin b12 from the
protein to which vitamin b12 is attached in food after this vitamin b12 combines
with a protein made by the stomach called intrinsic factor and is absorbed
by the body some people have pernicious anemia a

foods and is added to some fortified foods plant foods have no vitamin b12

the best sources of vitamin b12 fish meat poultry eggs milk and other dairy
products which also contain vitamin b12 some breakfast cereals nutritional yeast

b12 most people in the United States get enough vitamin b12 from the foods they
eat but some people have trouble absorbing vitamin b12 from food as a
result vitamin b12 deficiency affects between 1.5 percent and 15 percent of
the public your doctor can test your vitamin b12 level to see if you have a
deficiency certain groups may not get enough vitamin b12 or have trouble
absorbing it many older adults who do not have enough hydrochloric acid in
their stomach to absorb the vitamin b12 naturally present in food people over 50
should get most of their vitamin b12 from fortified foods or dietary
supplements because in most cases their bodies can absorb vitamin b12 from these
sources people with pernicious anemia whose bodies do not make the intrinsic
factor needed to absorb vitamin b12 doctors usually treat pernicious anemia
with vitamin b12 shots although very high oral doses of vitamin b12 might
also be effective people who have had gastrointestinal surgery such as weight
loss surgery or who have digestive disorders such as celiac disease or
Crohn’s disease these conditions can decrease the amount of vitamin b12 that
the body can absorb some people who eat little or no animal foods such as
vegetarians and vegans only animal foods have vitamin b12 naturally when pregnant

their babies might also not get enough vitamin b12 what happens if I don’t get
enough vitamin b12 vitamin b12 deficiency causes tiredness
weakness constipation loss of appetite weight loss and
megaloblastic anemia nerve problems such as numbness and tingling in the hands
and feet can also occur other symptoms of vitamin b12 deficiency include
problems with balance depression confusion dementia poor memory and
soreness of the mouth or tongue vitamin b12 deficiency can damage the nervous
system even in people who don’t have anemia so it is important to treat a
deficiency as soon as possible in infants signs of a vitamin b12
deficiency include failure to thrive problems with movement delays in
reaching the typical developmental milestones and megaloblastic anemia
large amounts of folic acid can hide a vitamin b12 deficiency by correcting
megaloblastic anemia a hallmark of vitamin b12 deficiency but folic acid

deficiency also causes for this reason healthy adults should not get more than
1000 mcg of folic acid a day what are some effects of vitamin b12 on health

get older some people develop dementia these people often have high levels of
homocysteine in the blood vitamin b12 with folic acid and vitamin
