Importance of Vitamin B12 in the human body

Vitamin B12 is an important vitamin for humans that plays a role in maintaining normal brain function, DNA synthesis, and nerve health. Deficiency can lead to serious problems, including anemia, neurological problems, and heart disease.

The best way to get your recommended daily allowance (RDA) of vitamin B12 is through food sources such as meat, poultry, seafood, dairy products, and eggs.

However, some people(vegans) may need to take supplements because they don’t eat enough animal-based foods or they have dietary restrictions. More than two-thirds of Americans don’t get enough vitamin B12 from food alone.

How Much Vitamin B12 Do I Need?

The RDA for vitamin B12 is 2.4 micrograms per day for adults ages 19 and up, according to the National Institutes of Health.

The RDA for pregnant women is 2.6 micrograms daily, and the RDA for breastfeeding women is 2.8 micrograms every day.

However, people with certain health conditions or who are at risk of vitamin B12 deficiency may need to take more than the RDA.

For example, people who have gastrointestinal problems or who are vegans may need to take more than the RDA. Some infants also need to take more than the RDA because they don’t get enough vitamin B12 from breast milk.

Functions of Vitamin B12 in the body
