Introduction: What is B12 and why is it important?
Cobalamin, commonly known as B12, is an essential nutrient that the human body requires for many different functions. B12 helps to maintain healthy red blood cells, nerves, and the digestive system. It is also involved in the production of DNA and RNA. Because the body does not produce B12, it must be obtained through dietary sources.
Certain groups of people are at a higher risk for developing a B12 deficiency. These groups include vegans and vegetarians, people with absorption disorders, older adults, and pregnant or breastfeeding women. A B12 deficiency can lead to side effects such as fatigue, weakness, constipation, loss of appetite, and weight loss.
Foods that are high in vitamin B12 include meat, poultry, fish, eggs, milk, and dairy products. Fortified foods such as cereals and nutritional yeasts are also good sources of vitamin B12.
Food sources of B12: Which foods contain B12?
B12 is found naturally in a variety of animal foods and is added to some fortified foods. Plant foods do not naturally contain vitamin B12, but fermented plant foods may be a source of B12 under certain conditions.
B12 is found naturally in animal foods including fish, shellfish, meat, and poultry. Vitamin B12 is generally not present in plant foods, but fortified cereals and other products are good sources of vitamin B12.
You can get recommended amounts of vitamin B12 by eating a variety of foods including the following:
-Beef liver and clams, which are the best sources of vitamin B12

The role of B12 in the body: What does B12 do in the body?
B12 is a nutrient that plays an important role in many of the body’s functions. It helps to produce energy, keep the nervous system healthy, and create new red blood cells. B12 is found naturally in animal foods, but it can also be made in a laboratory.
B12 is important for many of the body’s functions including:
– producing energy
– keeping the nervous system healthy
– creating new red blood cells
Deficiency symptoms: What are the symptoms of B12 deficiency?
There are a variety of symptoms that can occur if you are deficient in B12. These can range from mild to severe, and can even be life-threatening. Some of the most common symptoms include:
– pale skin
-Easy bruising or bleeding
-Shortness of breath
If you experience any of these symptoms, it’s important to see your doctor right away. They can order testing to see if you are deficient in B12, and if so, will recommend treatment.
Causes of B12 deficiency: Why does B12 deficiency occur?
The main causes of B12 deficiency are a lack of the vitamin in your diet and pernicious anemia.
Pernicious anemia is an autoimmune disorder that damages your stomach lining and prevents it from properly absorbing vitamin B12. Without treatment, pernicious anemia can be fatal.
B12 deficiency can also occur if you have certain gastrointestinal disorders, such as Crohn’s disease or celiac disease, that affect your body’s ability to absorb the vitamin.
If you follow a vegan diet, you may also be at risk for B12 deficiency because the vitamin is found mainly in animal-based foods.
Diagnosis of B12 deficiency: How is B12 deficiency diagnosed?
B12 deficiency is diagnosed through a blood test. The most common blood test used to diagnose B12 deficiency is the serum B12 test. This test measures the level of B12 in your blood.
When symptoms suggestive of B12 deficiency are present, your doctor will likely order a serum B12 blood test. If the serum B12 level is low, your doctor may also order one or more of the following tests to confirm a diagnosis of B12 deficiency:
-Methylmalonic acid (MMA) levels: MMA is an organic acid that is elevated in people with B12 deficiency.
-Hemoglobin and hematocrit levels: These tests are typically ordered to rule out other causes of anemia, such as iron deficiency.
-Folic acid level: This test may be ordered to rule out folate (vitamin B9) deficiency, which can cause similar symptoms as vitamin B12 deficiency.
Treatment of B12 deficiency: How is B12 deficiency treated?
B12 deficiency is treated with B12 shots or pills. The best way to get B12 is by injection, which goes straight into your bloodstream. You can also take B12 pills or give yourself B12 shots under the skin, but these methods are not as good as injections because they don’t raise your levels as high or as quickly.
Prevention of B12 deficiency: How can B12 deficiency be prevented?
B12 is found naturally in animal products, including fish, meat, poultry, eggs, and milk. For this reason, B12 deficiency is most common in vegans or vegetarians. The best way to prevent B12 deficiency is to eat foods that are fortified with B12 or to take a daily supplement.
