What Is Vitamin B12?
Vitamin B12 is water soluble, meaning that it is dissolved in water and transported through the bloodstream. It’s also known as cobalamin because vitamin B12 forms also contain the mineral cobalt. Among other things, it contributes to nerve cell health, the formation of red blood cells, and the synthesis of DNA. Considering its numerous crucial roles in our body, we need to consume a sufficient amount of food containing this essential vitamin.
Vitamin B12 Benefits
Cobalamin has a number of health benefits since it may prevent cardiovascular disease, improve your memory, and boost your energy. As it plays an important role in the production of red blood cells, it prevents anemia, a medical condition characterized by a low level of red blood cells, which are responsible for transporting oxygen to your vital organs.
Since vitamin B12 contributes to the normal development of a fetus’s brain and nervous system, it is necessary that pregnant women have an adequate intake of this nutrient. It can also lower the risk of premature birth or miscarriage.
One study from 2016 showed that vitamin B12 may prevent dementia and improve cognitive function. However, additional research is necessary in order to provide more evidence about the role of vitamin B12 supplement in enhancing memory and slowing down mental decline.
Although more research is needed to support the conclusions about the relationship between vitamin B12 and heart health, this nutrient helps the body lower the levels of homocysteine, which increases the risk of heart disease.
Sources of Vitamin B12
Animal products, such as meat, fish, eggs, and dairy products, are generally rich in vitamin B12. On the other hand, foods of plant origin don’t normally contain this nutrient, so vegetarians and vegans need to consume fortified food products, including breakfast cereals and nutritional yeast products. Below you can find a list of foods that are good sources of cobalamin, so try to include some of them in your eating plan.
We’ll start this vitamin B12 foods list with beef as it’s a very rich source of cobalamin. Beef liver is particularly high in this nutrient.

Recommended Daily Intake
The recommended dietary allowances (RDA) for all the nutrients are given in the Dietary Reference Intakes, which was created by the Food and Nutrition Board (FNB) at the Institute of Medicine of the National Academies. So if you’ve been asking yourself “How much vitamin B12 should I take?”, you can find the answer to this question below:
- From birth to 6 months – 0.4 mcg
- From 7 to 12 months – 0.5 mcg
- From 1 to 3 years – 0.9 mcg
- From 4 to 8 years – 1.2 mcg
- From 9 to 13 years – 1.8 mcg
- 14+ years – 2.4 mcg
As this vitamin is crucial for fetal development, pregnant women should increase their vitamin B12 intake to 2.6 mcg a day. Also, women who are breastfeeding need more vitamin B12, that is, 2.8 mcg per day to be more precise.
Vitamin B12 Deficiency
The symptoms of cobalamin deficiency include mouth ulcers, an inflamed tongue, problems with maintaining balance, mood changes, depression, and dementia. Low levels of vitamin B12 can also lead to megaloblastic anemia, which is characterized by fatigue, muscle weakness, shortness of breath, loss of appetite, and constipation or diarrhea. Furthermore, this type of nutrient deficiency may cause some neurological changes, including numbness and tingling in the hands and feet.
Since a lack of vitamin B12 can result in permanent nerve damage, it’s crucial to diagnose cobalamin deficiency on time and treat it properly. The treatment includes either high doses of oral vitamin B12 or a vitamin B12 injection.
Who Should Take Vitamin B12 Supplements?
Supplements of this vitamin are usually given to people who are at risk of developing a deficiency in this vitamin. For example, up to a third of elderly people have problems with the absorption of vitamin B12 due to atrophic gastritis. Also, people with pernicious anemia cannot absorb this vitamin, so they are usually treated with vitamin B12 shots.
Some gastrointestinal disorders, such as celiac disease and Crohn’s disease, may lead to a low concentration of vitamin B12 since they decrease its absorption. In addition, people who have undergone certain gastrointestinal surgical procedures can have inadequate levels of vitamin B12.
Since the sources of cobalamin are mostly foods of animal origin, strict vegetarians and vegans are likely to develop a deficiency in vitamin B12 if they don’t consume sufficient amounts of fortified food products or take dietary supplements. Pregnant and lactating women should be particularly careful if they follow a strict vegetarian or vegan diet as their infants may also develop cobalamin deficiency.
Vitamin B12 Side Effects
According to the Institute of Medicine of the National Academies, vitamin B12 is not toxic even if taken in large amounts. Since there is no evidence that too much vitamin B12 can have adverse effects on our health, this institution didn’t provide tolerable upper intake levels for this nutrient.
However, you should be cautious if you are taking supplements as they may have some side effects. Some of them include headaches, anxiety, itchy skin, and nausea. Therefore, never take dietary supplements without consulting your doctor.
Vitamin B12 or cobalamin is one of the essential nutrients because it plays a number of major roles in our organism. Besides contributing to the process of energy production, it is crucial to the formation of red blood cells and the synthesis of DNA. A balanced diet can usually provide us with a sufficient amount of this vitamin as various meats, fish, and seafood are rich in cobalamin. However, strict vegetarians and vegans need to include fortified food products, such as breakfast cereals, in their eating plan, so they don’t develop a deficiency in this vitamin. There are also dietary supplements that may help people who are likely to have inadequate levels of vitamin B12. It’s good to know that high vitamin B12 doses are not toxic, but cobalamin injections can have some unpleasant side effects.

Can you get B12 from plants?
Generally, plants don’t contain vitamin B12. However, this nutrient is usually added to cereals, soy products, nutritional yeasts, and other food products. Therefore, if you follow a strict vegetarian or vegan diet, you need to include these vitamin B12 foods in order to prevent cobalamin deficiency.
