Apparently healthy Indian lactovegetarians have significantly lower serum levels and urinary excretion of vitamin B12 as compared to non-vegetarians. The low levels of serum vitamin B12 in lactovegetarians are not due to defective absorption but to low dietary intake of this vitamin. Inspite of considerably low serum vitamin B12 values, the lactovegetarians have no apparent signs or symptoms of vitamin B12 deficiency and their response to injected cyanocobalamin mixed with tracer radioactive B12, as judged by urinary excretion pattern and liver uptake, was similar to that observed in non-vegetarians.

Top 10 foods high in B12 (Cobalamin)

Looking for an updated list of foods high in B12, the only links I came across were from draxe and a few other sites (you can google and find out yourself).

The semi-list below is from draxe. The list looks legitimate but this it is only partially correct.

  1. Beef liver: 1 ounce: 20 micrograms (over 300 percent DV)
  2. Sardines: 3 ounces: 6.6 micrograms (over 100 percent DV)
  3. Atlantic mackerel: 3 ounces: 7.4 micrograms (over 100 percent DV)
  4. …10

The unbiased list

See the difference in the 2 lists.

#1: Clams, Oysters, and Mussels

Shellfish are a great source of vitamin B12 and can be eaten raw, baked, steamed, fried, or made into chowder. In addition to vitamin B12 shellfish are a good source of zinc, copper, and iron. Clams provide the most vitamin B-12 with 98.9μg per 100g serving, accounting for 1648% of the DV. That is 84μg (1401% DV) per 3 ounce serving, and 187.9μg (3132% DV) in 20 small clams, or 9.4μg (156.6 %DV) in one small clam. Mussels and oysters are also good sources of B12 providing 600% DV and 400% DV per 100 gram serving.

#2: Liver

Often appearing on the culinary scene as pâté, liver can also be prepared steamed or fried with onions and herbs. The liver of most any animal is packed with vitamin B-12, the highest on the list are: Lamb, beef, veal, moose, turkey, duck, and goose respectively. Lamb liver provides 85.7μg (1428% DV) of vitamin B12 per 100g serving, or 72.85μg (230% DV) in a 3 ounce serving.

#3: Caviar (Fish Eggs)

Caviar and fish eggs are most often eaten as a garnish or spread. The eggs of whitefish contain the most vitamin B-12 with 56.4μg (940% DV) per 100g serving. Caviar contains a third of that with 20μg (333% DV) of vitamin B12 per 100g serving, 5.6μg (93% DV) per ounce, and 3.2μg (53% DV) per tablespoon. Chicken eggs, by comparison, only offer 1.29μg (22% DV) of vitamin B-12 per 100g serving, or 0.65μg (11% DV) per egg.

#4: Octopus

Popular in Mediterranean, Japanese, and Hawaiian cuisine, octopus is a vitamin b12 rich food. Cooked octopus provides 36μg of vitamin B-12 per 100 gram serving accounting for 600% of the DV. That is 30.6μg (510% DV) per 3 ounce serving, or 10.2μg (170% DV) per ounce. Raw octopus provides  about half as much vitamin b12 with 20μg (333% DV) per 100 gram serving, 17μg (283% DV)  in a 3 ounce serving, and 5.67μg (94.33% DV) per ounce.

#8: Lamb (Mutton)

Lamb is a common meat in the Middle East, Mediterranean, East Asia, Australia, New Zealand, and most of Europe. Lamb is a high cholesterol food so be sure to look for lean cuts which are higher in B12 anyway. Lamb also provides high amounts of protein, and zinc. The shoulder is the cut of lamb with the most vitamin B-12 providing 3.71μg (62% DV) per 100g serving, 5.82μg (97% DV) per pound, and 3.15μg (53% DV) in a 3 ounce serving.

#10: Eggs

When it comes to chicken eggs  the raw yellow has  most of the vitamin B-12 with 1.95μg per 100g serving (33%), however, this equates to 0.33μg per yolk or just 6% of the DV. The eggs of other animals are higher with a goose egg providing 7.34μg (122% DV) of vitamin B-12 per 100g serving, and a duck egg providing 3.78μg (63% DV).
