Your body needs vitamin B12 to help keep your nerve and red blood cells healthy and to make DNA, the genetic material in your cells. If you don’t get enough vitamin B12 you might develop anemia and feel tired and weak.
Vitamin B12 is naturally found only in animal foods such as meat, fish, seafood, poultry, eggs, milk, yogurt and cheese. It is also added to some foods and beverages like fortified plant based beverages, meat substitutes and nutritional yeast.
This fact sheet provides information on how much vitamin B12 you need and how to check if you get enough vitamin B12 in your diet.
Steps You Can Take
1. Find out how much vitamin B12 you need
|Age||Recommended daily amount of vitamin B12 (micrograms or mcg)||Stay below|
|1 - 3 years||0.9||
An upper limit for vitamin B12 has not been established
|4 - 8 years||1.2|
|9 - 13 years||1.8|
|14 - 70+ years||2.4|
Adults older than 50 years: Older adults do not absorb naturally occurring vitamin B12 very well. Adults over 50 should get the recommended amount of vitamin B12 from fortified foods or a supplement.
Vegetarians: Vegetarian diets, in particular vegan diets, need to be planned carefully to meet vitamin B12 needs. If you follow a vegan diet and avoid all animal foods including eggs, milk, yogurt and cheese, you'll need to get vitamin B12 from fortified foods and/or a supplement.
2. Find out how much vitamin B12 you eat
To estimate the amount of vitamin B12 in your diet, keep a food record for one or two days. Record what and how much you eat and drink. Add up the vitamin B12 in your diet using the amounts in foods listed below.
