Vitamin B12, also known as cobalamin, is a vital nutrient crucial to the body’s overall health.
What vitamin B12 does for the body is far-reaching, affecting everything from the nervous system to red blood cell production.
According to The American Journal of Clinical Nutrition, a deficiency in this important vitamin can lead to a wide range of health problems, many of which can be avoided with proper intake. This article discusses many ways in which vitamin B12 benefits your body and why it’s so important for your well-being.
What Vitamin B12 Does For The Body?
Vitamin B12 is involved in several critical processes in the body. The most notable include supporting brain function, producing red blood cells, and maintaining a healthy nervous system.
It also plays a role in DNA synthesis and energy production, making it essential for overall vitality.

1. Supports Brain Health
According to a study on Progress in Neurobiology, Vitamin B12 is essential for maintaining healthy brain function. It helps in the production of neurotransmitters, which are chemicals that allow communication between nerve cells.
A deficiency in B12 can result in cognitive decline, memory problems, and even mood disorders like depression and anxiety. It has also been linked to a lower risk of developing neurodegenerative diseases such as Alzheimer’s.

2. Promotes Red Blood Cell Formation
One of the most well-known functions of vitamin B12 is its role in the production of red blood cells. It works closely with folate to ensure the proper formation of these cells.
Without enough B12, the body can’t produce healthy red blood cells, leading to anemia. Symptoms of anemia include fatigue, weakness, and shortness of breath.

3. Maintains Nervous System Health
Vitamin B12 is involved in the production of myelin, a fatty substance that forms a protective sheath around nerve fibers. This myelin sheath ensures that nerve signals are transmitted efficiently.
Without sufficient B12, nerve damage can occur, leading to symptoms like tingling, numbness, and even difficulty walking.
4. Boosts Energy Levels
Vitamin B12 plays a significant role in the conversion of food into energy. It is involved in the metabolic process that turns carbohydrates into glucose, the primary source of energy for the body.

5. DNA Synthesis and Cell Division
Vitamin B12 also plays an important role in DNA synthesis and cell division. This is particularly vital for pregnant women, as a deficiency can lead to birth defects in the developing fetus. It’s essential for cell growth and the proper development of tissues throughout the body.

6. Improves Mood and Mental Health
There is growing evidence that vitamin B12 plays a role in the regulation of mood and mental health. It is thought to work in tandem with folate to produce serotonin, a neurotransmitter that regulates mood. A deficiency in B12 can contribute to feelings of depression and anxiety.
How to Get Enough Vitamin B12
Most people can obtain enough vitamin B12 through a balanced diet that includes animal-based foods. Here are some excellent sources of vitamin B12:
