Vitamin B12, commonly known as cobalamin, is a water-soluble vitamin that plays an important role in metabolism. It is one of the eight B vitamins. Animals use it as a catalyst in DNA synthesis as well as lipid and amino acid breakdown. Vitamin B12 is the most structurally complicated of all vitamins and is the sole vitamin that human beings must obtain from animal-derived meals or supplements. Only a few microbial species can produce vitamin B12.


Vitamin B12, commonly known as cobalamin, is a water-soluble vitamin that is found normally in certain foods, added to others, and synthesised in the intestinal tract by bacteria. It plays an important role in a variety of internal processes, such as:

  • Formation of Red Blood cells: Vitamin B12 is essential for your body’s production of RBCs. Low vitamin B12 levels can reduce red blood cell production and prevent them from properly growing. Red blood cells are tiny and circular in healthy people, but they may grow bigger and oval with vitamin B12 deficiency. Anaemia occurs when your body does not produce enough red blood cells to carry oxygen to your important organs. This might result in symptoms such as exhaustion and weakness.
  • May prevent depression: Your mood may be elevated by vitamin B12. There is still much to learn about how vitamin B12 affects mood. However, this vitamin is essential for the synthesis and metabolism of serotonin, a neurotransmitter that regulates mood. As a result, a lack of vitamin B12 may result in less serotonin being synthesised, which could affect one’s mood. Although evidence does not yet support that vitamin B12 supplements have the same impact in persons with normal B12 levels, those with a deficit may benefit from mood and depression improvements.
  • May reduce your risk of macular degeneration:  Macular degeneration is a retinal condition that mostly impacts your central vision. AMD caused by age may be reduced by ensuring appropriate vitamin B12 levels. Homocysteine is a sort of amino acid that is commonly found in your bloodstream, and researchers think that taking vitamin B12 supplements may reduce your blood levels of it. Ultimately, further research is required to completely comprehend vitamin B12’s contribution to macular degeneration prevention and visual wellness.

However, there is some evidence to support it that vitamin B12 may help people in certain domains. To strengthen the present findings even more, additional study is required. Therefore, it is always good to speak with your doctor about the requirement and proper dosage of vitamin B12.


Vitamin B12 is a vitamin that helps build DNA, the genetic material in all of your cells, and keeps your body’s blood and nerve cells healthy. Vitamin B12 also helps to avoid megaloblastic anaemia, a blood disorder that causes fatigue and weakness. Vitamin B12 functions in the human body by assisting in the synthesis of red blood cells.

Haemoglobin, the protein in charge of transporting oxygen throughout the body, is made easier by it. By promoting the synthesis of myelin, a protective coating for nerve fibres that promotes effective communication between the brain and other areas of the body, vitamin B12 also contributes to the maintenance of a healthy nervous system. Vitamin B12 is also essential for DNA synthesis and cell division. It is crucial for general growth and development since it participates in the metabolism of several amino acids and fatty acids.


There are no set guidelines for how much Vitamin B12 is good for each individual because it depends on factors such as age, overall health, and dietary preferences. It is best to speak with a healthcare practitioner to figure out the optimal Vitamin B12 dose for your particular case. They can provide you personalised guidance and make sure you’re getting enough to suit your nutritional needs. However, it is often advised that people strive for a daily dose of 2.4 mcg of vitamin B12. This may be gained through foods including meat, fish, dairy products, and fortified meals. Regular blood tests can also help you check your Vitamin B12 levels and determine whether you need to supplement.

Always seek the advice of a healthcare expert to ensure your health and well-being. However, it is critical to speak with a healthcare practitioner to identify the proper dose for your unique requirements, as well as any possible adverse effects with other medications or health issues.
