VITAMIN B12

  Cobalamin, which is another name for vitamin B12, is a water-soluble vitamin that is important for the brain, nervous system, and red blood cell formation. 

It is necessary for the metabolism of carbohydrates, proteins, and fats, making it one of the eight B vitamins.

   Vitamin B12 is an essential nutrient required for the proper functioning of the nervous system, DNA synthesis, and the production of red blood cells. 

A deficiency in vitamin B12 can lead to a range of health problems. 

However, since this vitamin is mainly found only in foods of animal origin such as meat, fish, poultry, eggs and dairy products, vegetarians and vegans may need to supplement or consume fortified foods to get enough of it.

   A condition known as pernicious anemia, which is characterized by a decrease in the body's number of red blood cells, can result from a vitamin B12 deficiency. 

Different side effects of a lack of vitamin B12 can include shortcoming, weariness, deadness or shivering in the hands and feet, trouble strolling, gloom, and cognitive decline.

   People who are at risk of deficiency should talk to their doctor or a registered dietitian to find out the best way to get enough vitamin B12.

 

SOURCES

 As mentioned earlier, vitamin B12 is naturally found in animal products, such as meat, fish, eggs, and dairy products. 

For people who follow a vegan or vegetarian diet, plant-based foods fortified with vitamin B12, such as breakfast cereals, plant-based milk alternatives, and nutritional yeast, can be a good source.

ABSORPTION

 Vitamin B12 requires a protein called intrinsic factor, which is produced in the stomach, to be absorbed properly. 

People with certain medical conditions, such as pernicious anemia or gastrointestinal disorders, may have difficulty producing intrinsic factor and therefore have a higher risk of vitamin B12 deficiency.

 

HEALTH BENEFITS

Here are some of the health benefits of vitamin B12:

•      Energy production: Vitamin B12 plays a key role in the metabolism of carbohydrates and fats, which are essential for energy production.

•      Red blood cell formation: Vitamin B12 is essential for the formation of red blood cells, which transport oxygen throughout the body.

•        Nervous system function: Vitamin B12 helps to maintain the health of the nervous system by playing a role in the synthesis of myelin, a fatty substance that covers and protects nerve fibers.

•       Cognitive function: Vitamin B12 is important for cognitive function and may help to reduce the risk of cognitive decline in older adults.

•       Heart health: Vitamin B12 may help to lower levels of homocysteine, an amino acid that has been linked to an increased risk of heart disease.

•        Mood regulation: Vitamin B12 plays a role in the production of serotonin, a neurotransmitter that regulates mood.

•        Skin health: Vitamin B12 may help to improve skin health by reducing inflammation and supporting the production of healthy skin cells.

  In addition to its role in red blood cell formation and nervous system function, vitamin B12 may also have other health benefits. 

Some studies have suggested that it may help lower the risk of heart disease, improve mood and depression symptoms, and boost brain function in older adults.

 

RECOMMENDED INTAKE

   The recommended daily intake of vitamin B12 for adults is 2.4 micrograms.

 However, some people may require higher doses if they have a deficiency or certain medical conditions. 

It's important to talk to a healthcare provider before starting any vitamin supplements.

 

TESTING FOR DEFICIENCY

   Blood tests can be used to check for vitamin B12 deficiency. Symptoms of deficiency may include fatigue, weakness, numbness or tingling in the hands and feet, difficulty walking, and memory problems.

 

SYMPTOMS OF VITAMIN B12 DEFICIENCY

   Fatigue, weakness, and lightheadedness.

   Pale skin and yellowing of the skin and eyes (jaundice).

   Tingling or numbness in hands and feet.

   Difficulty walking or balance problems.

   Shortness of breath and heart palpitations.

   Digestive problems such as diarrhea, constipation, or loss of appetite.

   Numbness or tingling in hands and feet and depression.

   Difficulty walking or balance problems.

   Long-term vitamin B12 deficiency can lead to neurological problems, such as dementia, nerve damage, and in severe cases, paralysis.

   Unlike other B vitamins, vitamin B12 is not found in plant-based foods. It is naturally present in animal products, such as meat, fish, eggs, and dairy products. 

Some fortified breakfast cereals, plant-based milk alternatives, and nutritional yeast also contain vitamin B12.

    Deficiency in vitamin B12 can lead to various health problems, including anemia, nerve damage, and cognitive impairment. 

It is particularly common among older adults, vegetarians and vegans, and people with certain medical conditions that affect the absorption of nutrients in the gut.

Supplementation with vitamin B12 is recommended for individuals who are at risk of deficiency. It is available in various forms, including oral supplements, injections, and nasal sprays. 

The recommended daily intake of vitamin B12 for adults is 2.4 micrograms.

 

SOME OF THE CAUSES, AND TREATMENTS OF VITAMIN B12 DEFICIENCY

 

Causes

   Inadequate intake of vitamin B12 through diet (found in animal products such as meat, fish, eggs, and dairy)

   Malabsorption due to conditions such as pernicious anemia, celiac disease, inflammatory bowel disease, or surgical removal of part of the stomach or small intestine

   Reduced ability to absorb vitamin B12 due to aging or medications that decrease stomach acid production

 

Treatment

   Treatment for vitamin B12 deficiency typically involves vitamin B12 injections or supplements. 

In some cases, dietary changes may also be recommended. 

It's important to talk to your doctor or your healthcare provider if you suspect you may have a vitamin B12 deficiency.

Increasing vitamin B12 intake through diet or supplements.

Intramuscular injections of vitamin B12 for severe deficiency or malabsorption problems.

Addressing underlying conditions that may be causing malabsorption.

Regular monitoring of vitamin B12 levels to ensure proper treatment.

   It's important to note that vitamin B12 deficiency can have serious health consequences if left untreated, so if you are experiencing symptoms or have concerns about your vitamin B12 levels, it's important to consult with a healthcare provider.
