Vitamin B12, essential for maintaining the health of nerve and blood cells, is a vital nutrient that our body cannot produce on its own. Let’s see what the vitamin does and how to get the required amount through Vitamin B12 rich foods.
What is Vitamin B12 ?
Vitamin B12 is a water-soluble vitamin essential for brain function, nerve tissue health, and the production of red blood cells. It plays a pivotal role in DNA synthesis and is crucial for metabolism.
Water soluble vitamins are not stored in large amounts by the body, so they need to be consumed regularly through diet. The other water-soluble vitamins include:
Vitamin B1 (Thiamine): Essential for converting nutrients into energy, it also plays a role in nerve function.
Vitamin B2 (Riboflavin): Involved in energy production and cellular function, and also acts as an antioxidant.
Vitamin B3 (Niacin): Necessary for energy metabolism, it is also involved in DNA repair and stress response signaling.
Vitamin B5 (Pantothenic Acid): Involved in the synthesis of coenzyme A, which is essential for the metabolism of fats, carbohydrates, and proteins.
Vitamin B6 (Pyridoxine): Plays a crucial role in amino acid metabolism, and is also involved in the production of neurotransmitters and red blood cells.
Vitamin B7 (Biotin): Essential for the metabolism of fatty acids, amino acids, and glucose. It also plays a role in gene regulation.
Vitamin B9 (Folate or Folic Acid): Necessary for DNA synthesis and repair, and is particularly important during periods of rapid cell division and growth, such as during pregnancy.
Vitamin C (Ascorbic Acid): An antioxidant that is also involved in the synthesis of collagen, absorption of iron, and modulation of the immune system.
These water-soluble vitamins are generally found in a variety of foods, including fruits, vegetables, grains, and animal products. Since they are not stored in the body in large amounts, it is important to consume them regularly to meet the body’s needs and maintain health.
The Role of Vitamin B12 in the Body
1. Vitamin B12 and Blood Formation
Vitamin B12 plays a critical role in the formation of red blood cells. It is essential for the synthesis of DNA, which is crucial for the division of cells, including those in the bone marrow that develop into red blood cells.
Additionally, Vitamin B12 is involved in the production of heme, a component of hemoglobin, the protein in red blood cells that carries oxygen throughout the body.
When there is a deficiency in Vitamin B12, red blood cells can become enlarged and irregular in shape, resulting in a condition known as megaloblastic anemia.
This type of anemia is characterized by a reduced ability of the blood to carry oxygen, which can lead to symptoms like fatigue and weakness.
2. B12’s Contribution to Nervous System Health
The nervous system is highly dependent on Vitamin B12 for proper functioning. B12 is necessary for the synthesis of myelin, the protective sheath that surrounds nerve fibers and helps ensure the rapid and efficient transmission of electrical impulses.
Without sufficient Vitamin B12, the myelin sheath can become damaged, leading to a range of neurological problems. Furthermore, Vitamin B12 plays a role in the metabolism of neurotransmitters, which are chemical messengers that facilitate communication between nerve cells.
Deficiency in Vitamin B12 can lead to symptoms such as numbness, tingling in the extremities, mood changes, and impaired cognitive function.
3. How Vitamin B12 Supports Energy Metabolism
Vitamin B12 is an essential player in the body’s energy metabolism. It acts as a coenzyme in various metabolic processes that are involved in the conversion of nutrients from the food we eat into adenosine triphosphate (ATP), the energy currency of the cell.
Specifically, Vitamin B12 is involved in the metabolism of fatty acids and amino acids, and it helps in the conversion of homocysteine to methionine, an essential amino acid.
Without adequate levels of Vitamin B12, the energy-yielding metabolism can become inefficient, leading to symptoms such as fatigue and a lack of energy.
This is why individuals with B12 deficiency often experience tiredness and reduced physical stamina.
Now, Let’s see how much Vitamin B12 is required for us to function well.
Recommended Daily Allowance (RDA) of Vitamin B12
The RDA values are established by the Food and Nutrition Board of the Institute of Medicine (National Academy of Medicine) in the United States
- Infants 0-6 months: 0.4 micrograms (mcg) per day
- Infants 7-12 months: 0.5 mcg per day
- Children 1-3 years: 0.9 mcg per day
- Children 4-8 years: 1.2 mcg per day
- Children 9-13 years: 1.8 mcg per day
- Adolescents and Adults 14 years and older: 2.4 mcg per day
- Pregnant women: 2.6 mcg per day
- Breastfeeding women: 2.8 mcg per day
How about if we aren’t receiving the necessary amounts of this vitamin?

Vitamin B12 deficiency can be very serious if left untreated. It can lead to anemia, nerve damage, and impaired brain function.
In severe cases, the neurological complications can be irreversible. It’s important to address B12 deficiency promptly with dietary changes or supplementation as advised by a healthcare provider.
Which Vegetable Is Rich In Vitamin B12?

How Many Eggs Is Enough For B12?
Eggs are not as rich in Vitamin B12 as some other animal products. One large egg contains about 0.6 micrograms of Vitamin B12.

Can I Get Too Much Vitamin B12?
Vitamin B12 has a low potential for toxicity as it is water-soluble, and excess amounts are usually excreted in urine.
However, extremely high doses of supplements can sometimes be associated with side effects or may mask the diagnosis of other health issues.
Should I Take Vitamin B12 Supplements?
Whether or not you should take Vitamin B12 supplements depends on your dietary intake, health status, and specific needs.
