Top 10 Foods Highest in Vitamin B12 (Cobalamin)


Vitamin B-12, or Cobalamin, is the largest and most complex vitamin currently known to man. A slight deficiency of vitamin B-12 can lead to anemia, fatigue, mania, and depression, while a long term deficiency can potentially cause permanent damage to the brain and central nervous system. Vitamin B-12 can only be manufactured by bacteria and can only be found naturally in animal products, however, synthetic forms are widely available and added to many foods like cereals. Vitamin B-12 can be consumed in large doses because excess is excreted by the body or stored in the liver for use when supplies are scarce. Stores of B-12 can last for up to a year. Below is a list of the top ten vitamin b12 rich foods. Click here for other foods high in vitamin b.

Health Benefits of Vitamin B12

  • Protect Against Heart Disease - Adequate levels of vitamins B12, B6, and B9have been shown to lower levels of a protein in the blood: homocysteine. Lower levels of homocysteine has been shown to improve endothelial function, which in turn may boost cardiovascular health and decrease risk of heart attacks.3-5
  • Protect and Repair DNA to Reduce Cancer Risk and Slow Aging - Absorption of vitamin b12 and Folate (B9) is essential for DNA metabolism and maintenance which helps to prevent cancer and slow aging.6 Read full blog post here...
  • Protect Against Dementia and Cognitive Decline - Lack of vitamin B12 increases homocysteine levels, which in turn decreases the bodies ability to metabolize neurotransmitters.7 Due to limitations with creating long term controlled studies in human populations, no definite link between increased vitamin b12 levels and cognitive function have been found,8-12 however several observational studies suggest increased homocysteine levels increase the incidence of Alzheimer's disease and dementia,13-15 and low levels of vitamin B12 has been associated with cognitive decline.16
  • Alzheimer's Protection - A study has shown that a deficiency in Vitamin B12 and Folate (B9) can double the risk of Alzheimer's Disease.17
  • Energy and Endurance - A lack of vitamin B12 will lead to anemia and weakness. Adequate levels of vitamin B12 are necessary to maintain normal energy levels. Claims of vitamin B12 as an energy or atheletic enhancer remain unproven.18

People at Risk of a Vitamin B12 Deficiency

  • Older Adults who have Atrophic Gastritis - A condition affecting 30-50% of adults over age 50 and hampers their ability to absorb vitamin B12 from natural foods. Supplements are recommended for people in this group.
  • People with Pernicious Anemia - A condition that affects 1-2% of adults and can only effectively be treated with vitamin B12 injections or shots.
  • Vegans and Vegetarians - Vitamin B12 is naturally found in animal products, however there are some natural vegetarian foods high in vitamin b12 and various fortified B12 foods for vegans.
  • Pregnant and Lactating Women who are Vegetarian or Vegan
  • People taking Certain Medications
    • Proton pump inhibitors, such as omeprazole (Prilosec®) and lansoprazole (Prevacid®), which are used to treat gastric or pepetic ulcer disease can inhibit absorption of vitamin B12.
    • Metformin - often used for type II diabetes, may interfere with vitmain B12 absorption in certain people.
    • Histamine antagonists, such as cimetidine (Tagamet®), famotidine (Pepcid®), and ranitidine (Zantac®), used to treat peptic ulcer disease, can reduce absorption of vitmain B12 by slowing the release of hydrochloric acid into the stomach.
    • Bacteriostatic Antibiotics, like Chloramphenicol (Chloromycetin®), can interfere with the red blood cell response to vitamin b12 supplements.

Warnings

  • Liver, Fois Gras, Whole Milk, Clam Chowder, Liverwurst, Salami, Cheese, Caviar, Lamb, Shell Fish, and Beef are high cholesterol foods which should be eaten in moderate amounts and avoided by people at risk of heart disease or stroke.
