Vitamin B12



Why is Vitamin B12 important?
Vitamin B12 is needed to keep your blood healthy and is used by the body to make proteins. Most people can easily get all the vitamin B12 they need from food, but some groups of people, such as vegans, have to work harder to get enough vitamin B12 in their diets. Having a diet that is too low in vitamin B12 over time can cause anemia (a condition that occurs when you don't have enough healthy red blood cells) or problems with memory and confusion.

How much Vitamin B12 do I need every day?
The amount of vitamin B12 you need each day, or recommended daily allowance (RDA), depends on your age. If you are 9 to 13 years old, you need 1.8 micrograms each day. If you are 14 years old or older, you need 2.4 micrograms of vitamin B12 each day.

What foods are good sources for Vitamin B12?
Vitamin B12 is found naturally in animal products and is also added to certain foods. Good sources of vitamin B12 include:
  • Fish and seafood
  • Meat
  • Poultry
  • Eggs
  • Cheese
  • Milk
  • Yogurt
  • Fortified foods such as cereals
If you are a vegan (a vegetarian who does not to eat any animal products), then you should take a vitamin supplement or eat fortified foods (foods that have vitamin B12 added). Check food labels to find products such as breakfast cereals, cereal bars, soy milk, and meat substitutes that are fortified with vitamin B12. You can also add nutritional yeast to soups and casseroles to get more vitamin B12.
