Vitamin B12-rich food items and their benefits

Team AckoJan 17, 2024

Vitamins are essential for the body to function smoothly and protect from diseases. While you require different types of vitamins for a healthy body, Vitamin B12 is vital, as it helps maintain and regulate the most fundamental structure — the DNA. Thus, you must be aware of how to consume sufficient amounts of Vitamin B12 naturally. Here’s a detailed article on the list of Vitamin B12-rich food items and their benefits, and information on vitamin deficiency.




What is Vitamin B12?

Cobalamin, commonly known as Vitamin B12, is a type of vitamin that your body needs to function smoothly. It is naturally found in meat-based diets. It can also be added to certain foods as a supplement. Vitamin B12 is necessary for red blood cells and DNA synthesis. Additionally, it is essential for the formation and function of nerve and brain cells. 

Role of Vitamin B12

Vitamin B12 is required for good blood circulation. When the body lacks B12, it reduces normal red blood cell synthesis (causing anaemia), leading to compromised oxygen transport. Other important functions of Vitamin B12 in the body include the following.

  1. Helping the brain and nervous system to function normally

  2. Helping in reducing congenital disabilities

  3. Aiding the formation of red blood cells

  4. Assisting in energy production

  5. Protecting the eyes against macular degeneration

  6. Providing the ability to think clearly

  7. Helping in the prevention of anaemia

  8. Assisting in the creation and regulation of DNA
