Vitamin B12, also known as cobalamin is an essential vitamin that helps make your DNA and red blood cells. Thus, it is an important source of making your genetic material. Also, it helps you prevent against a type of anemia known as ‘megaloblastic anemia’ in which people grow symptoms like weakness and tiredness.

How it gets absorbed in the Body?

The process is divided into two steps which are as follow:

  1. Vitamin B12 comes from protein content in the food. First of all, HCl in the stomach separates it from its source.
  2. Later, it combines with another protein in the stomach, known as the intrinsic factor and only then it can be absorbed by the body.

Your body does not produce vitamin B12 on its own thus you have to take it from external sources that could either supplement or animal-based foods. Also, you need to take it on regular bases as the body does not store it for long. The daily requirement of vitamin B12 depends upon certain factors that include:

  • Age
  • Physical condition
  • Eating habits
  • Medicines (if you are taking any)

Thus, the average recommended dose varies mainly with age, such as:

  • Infants up to 6 months: 0.4 mcg
  • Babies (7-12 months): 0.5 mcg
  • Kids (4-8 years): 1.2 mcg
  • Children (9-13 years): 1.8 mcg
  • Teens: (14-18 years): 2.4 mcg
  • Adults: (18 years above): 2.4 mcg (if pregnant 2.6 mcg per day, if breastfeeding 2.8 mcg per day)
