You must obtain vitamin B12 from your diet or from supplements as your body cannot produce it on its own.
Animal liver and kidneys
One of the foods that is highest in nutrients is organ meat. Lamb’s liver and kidneys, in particular, are high in vitamin B12.
While beef or veal liver typically have less vitamin B12 than lamb liver, 3.5 ounces (100 grammes) of the latter two may still provide roughly 3,000% of the DV.
Beef
A great source of vitamin B12 is beef. 190 grammes of grilled flat iron steak contain 467% of the daily value (DV) for vitamin B12.
The amount of steak contains more than 100% of the DVs for selenium and zinc, as well as adequate quantities of the vitamins B2, B3, and B6.
Fortified cereal
Given that it is synthetically produced and not sourced from animal sources, this source of vitamin B12 may be suitable for vegetarians and vegans.
Tuna
Fish like tuna, which is frequently eaten, is a fantastic source of vitamins, minerals, and protein. High levels of vitamin B12 are present, particularly in the black muscles that are located just beneath the skin.
Salmon
One of the foods with the largest amounts of omega-3 fatty acids is salmon, which is well known for this. Additionally, it’s a top B vitamin source.
Milk and dairy products
Several vitamins and minerals, including vitamin B12, can be found in abundance in milk and other dairy products like yogurt and cheese.
