Why Is Vitamin B12 Essential for You

Vitamin B is necessary for various bodily functions, such as:-

1. Red Blood Cell Production

Vitamin B12 is critical in producing healthy red blood cells (RBCs). The blood cells play a crucial role in carrying oxygen from the lungs to various body organs. Due to an inadequate vitamin B12 in the body, there can be less production of RBCs, leading to a medical condition called megaloblastic anemia. 

It is a health problem in which RBCs become enlarged and fragile, making them less effective in transferring oxygen. You may have symptoms like pale skin, fatigue, and weakness. 

2. Nervous System Function

To ensure the health of nerve cells, you must have adequate vitamin B12 levels. It helps the formation of the myelin sheath, i.e., a protective layer covering the surroundings of nerve fibers and facilitating the transmission of nerve signals. 

If there is vitamin B12 deficiency, the myelin sheath may deteriorate, leading to neurological problems. You may suffer symptoms such as numbness or tingling in the hands & feet, muscle weakness, memory problems, and balance issues. 

3. DNA Synthesis

Vitamin B12 plays a vital role in the synthesis of DNA. It is a genetic material present in every cell of the body. With adequate vitamin B12 levels, there is proper cell division and growth. It ensures the renewal and repair of tissues and organs. Due to insufficient vitamin B12, overall cellular function and health are adversely affected. 

4. Energy Metabolism

Vitamin B12 helps with the conversion of food into energy in the body. If you have a deficiency of vitamin B12, your body’s energy production is compromised. You may suffer from health issues, such as poor metabolism, fatigue, and weakness.

5. Brain Health

As per medical research, vitamin B12 is essential for cognitive function. With adequate vitamin  B12 levels, you may have good brain health and mental peace.

6. Supporting the Immune System

Vitamin B12 supports the formation of white blood cells, which help the body defend against diseases & infections. 

Causes of Vitamin B12 Deficiency

1. Dietary Insufficiency

If your diet lacks B12-rich foods, you may struggle with the deficiency. You may note that vitamin B12 is often found in animal-derived foods, such as eggs, fish, and dairy.


Due to digestive problems, your body may be unable to absorb vitamin B12. Pernicious anemia is an autoimmune disorder that impairs the body’s ability to absorb the vitamin from food and supplements. 

3. Medication

Some medications may interfere with vitamin B12 absorption when used over the long term. 

4. Surgery

Some surgical procedures, like weight-loss surgery, require an alteration of the stomach or small intestine. It lowers the absorption of vitamin B12, leading to deficiency.

5. Aging

Stomach acid is essential for releasing vitamin B12 from food. However, as people age, they may produce less stomach acid, leading to decreased absorption.
