What is Vitamin B12?
Vitamin B12 originates from bacteria, fungi and algae and is present in the tissue of most animals. Plants can contain miniscule amounts from microbial contamination, but not in a form available for humans to consume.
Although it is a water soluble vitamin, the body is able to store it in the liver, with excess amounts being removed from the body through urination.
Vitamin B12 Intake
This B vitamin is attainable through a balanced diet, but vegetarians and vegans may have more difficulty reaching their Recommended Daily Allowance. It is suggested that adults consume 2.5mcg a day.
Eggs, meat, poultry, shellfish, milk, and milk products are all nutritional sources of the vitamin; although boiling milk may destroy most of it. Supplements are also available in caplet and tablet form, which can be useful for vegetarians and vegans.
