In order to stay healthy vitamin B12 should be enough and ensured to be made more. A lot of things for the body are done by Vitamin B12. As an example, it helps make the DNA and the red blood cells

Since Vitamin B12 is not made by the body, it has to be taken from animal-based foods or from supplements. And this should be done on a frequent basis, because the body doesn’t store vitamin B12 for a long time.

The answer depends on factors including your age, eating habits and medical conditions, and what medications being taken.

The average suggested amounts to be consumed, measured in micrograms (mcg), differ by age:

  • Infants up to age 6 months: 0.4 mcg
  • Babies age 7-12 months: 0.5 mcg
  • Children age 1-3 years: 0.9 mcg
  • Kids age 4-8 years: 1.2 mcg
  • Children age 9-13 years: 1.8 mcg

  • Adults: 2.4 mcg (2.6 mcg per day if pregnant and 2.8 mcg per day if breastfeeding)

Vitamin B12 – Food Sources

Vitamin B12 can be found in animal foods, which have it naturally, or from items that have been fortified with it.

Sources of animal include dairy products, eggs, fish, meat, and poultry. If food fortified with B12 is being looked for, check the product’s Nutrition Facts label.

Vitamin B12 – Deficiency

This nutrient is found enough in most people in US. If not sure, then the doctor should be consulted for the requirement of blood test if needed to check level of Vitamin B12

It can become harder to absorb this vitamin with growing age. It can also happen because of past medical history such as weight loss surgery or another operation that removed part of the stomach, or if drinking heavily.

Chances for developing vitamin B12 deficiency are more if having:

  • Atrophic gastritis, in which the stomach lining has thinned
  • Pernicious anemia, which makes it difficult for the body to absorb vitamin B12
  • Conditions affecting the small intestine, such as Crohn’s disease, celiac disease, bacterial growth, or a parasite
  • Immune system disorders, such as Graves’ disease or lupus
  • Certain medications being consumed that interfere with the absorption of B12 which includes some heartburn medicines including proton pump inhibitors (PPIs) such as esomeprazole (Nexium), lansoprazole (Prevacid), omeprazole (Prilosec OTC), pantoprazole (Protonix), and rabeprazole (Aciphex), H2 Blockers such as cimetidine (Tagamet) and famotidine (Pepcid AC); and certain diabetes medicines such as metformin (Glucophage).

Vitamin B12 deficiency can also happen if following a vegan diet that is not eating any animal products, including meat, milk, cheese, and eggs or  a vegetarian who doesn’t eat enough eggs or dairy products to meet the vitamin B12 requirements. In both of those cases, fortified foods can be added to the diet or supplements can be taken to meet this need.

Pregnant or New Mom

If a pregnant woman is on a vegan or vegetarian diet, and plans to only breastfeed the baby, the doctor should be consulted before having a baby, so that a plan is in place for how to get enough vitamin B12 to keep the baby healthy.

The baby could have developmental delays and not thrive and grow like he should due to lack of vitamin B12.

Adults who are older and having a vitamin B12 deficiency will likely have to take a daily B12 supplement or a multivitamin that contains B12.
