Vitamin B12 supplements are available in a wide range of doses as well, including high dose supplements with 1,000–2,000 mcg per serving.

Researchers have found that many medical conditions can result in the malabsorption of B12 besides a B12-deficient diet. These include Crohn’s disease and having had a gastrectomy. Low levels of vitamin B12 are easily missed because the signs of deficiency can resemble other conditions, or they may be simply ignored because of their gradual onset.
