Animal liver and kidneys Organ meats are some of the most nutrient-packed foods. Liver and kidneys, especially from lamb, are rich in vitamin B12. A 3.5-ounce (100-gram) serving of lamb liver provides an incredible 3,571% of the Daily Value (DV) for vitamin B12 ( 1 ).
How to raise your B12 levels fast. The most common way to treat B12 deficiencies is by adjusting your diet. If this is unsuccessful, vitamin supplements may be recommended. If you're looking to boost the amount of vitamin B12 in your diet, you should eat more animal products, like meat, seafood, dairy and eggs.
The amount of vitamin B-12 in beef depends on the cut, lean fat-trimmed chuck contains the most vitamin B12 with 6.18μg (103% RDA) per 100g serving, 11.49μg (103% RDA) in a chuck steak, and 5.25μg (88% RDA) in a 3 ounce serving. Chuck is followed by sirloin (62% RDA), rib-eye (60% RDA), and ribs (58% RDA).
Note that meats vary with respect to amount of vitamin B12 they contain e.g. beef liver is a much richer source of vitamin B12 than a chicken breast (see table below).
Vitamin B12
The recommended daily intake of B12 is about 2µg, with a serving of two eggs satisfying 15% of your everyday requirements.
Vegetables– Usually, most vegetables contain some amount of Vitamin B12, but there are some Vitamin B12 foods for vegetarians that contain a very high amount of Vitamin B12 namely- Spinach, Beetroot, Potatoes, Mushrooms, alfalfa, and others.
Cooking doesn't destroy it. Vitamin B-12 doesn't break down—even at the boiling point of water—for several hours. A diet low in animal proteins, milk, or dairy foods may increase the need for vitamin B-12.
Chicken is another good source of Vitamin B12, protein and lean fat. The recommended daily amount of vitamin B-12 for adults is 2.4 micrograms. One cup of chicken gives you roughly 12 micrograms. If your daily diet includes chicken in some form, then be assured that your body won't be nutritionally deficient.
Meat contains protein-bound vitamin B12, but it's not an ideal source for B12 for two main reasons: First, the protein-bound B12 in animal foods can be difficult to absorb. The free, or un-bound, crystalline form found in fortified plant foods is preferred because it's more easily absorbed.
In the stomach, hydrochloric acid and enzymes unbind vitamin B12 into its free form. From there, vitamin B12 combines with a protein called intrinsic factor so that it can be absorbed further down in the small intestine. Supplements and fortified foods contain B12 in its free form, so they may be more easily absorbed.
Bananas also contain fibre and potassium. It helps manage blood pressure, reduce stress, and relieve constipation and ulcer problems. The fruit also helps regulate body temperature. Another fruit that is rich in vitamin B12 is blueberries.
It's an excellent source of vitamins B1, B2, B3 and B9. The Reduced Salt version even contains vitamins B6 and B12. These vitamins may support brain health and reduce fatigue, anxiety, stress and heart disease risk.
Diet. Some people can develop a vitamin B12 deficiency as a result of not getting enough vitamin B12 from their diet. A diet that includes meat, fish and dairy products usually provides enough vitamin B12, but people who do not regularly eat these foods can become deficient.
Clams. Other body benefits: Not only do clams have the highest concentration of vitamin B12 of any food, they're also filled with potassium. Three ounces of either canned or fresh clams contain 534 mg of potassium, 15% of your DV.
Blueberry is another fruit with high vitamin B12 rich fruit. Blueberry contains many antioxidants that keep our health and skin pure and healthy.
Fish is a source of B12. We need to get 2.5 micrograms of B12 everyday. You can get 4 micrograms in 100g of tinned red salmon and tuna and between 8 and 13 micrograms in 100g of tinned mackerel or sardines.
One hard-boiled egg has about 0.6 micrograms of B12. That's 25% of your daily value. But you'll need to eat the whole egg. Most of the B12 comes from the yolk.
Our ancestors would get their B12 supply in the form of bacteria on root vegetables/tubers pulled from the ground, by drinking water from natural sources, as well as from any meat they happened to consume (since those animals also ingested bacteria from soil and water).
Beetroots are enriched with iron and are also a storehouse of Vitamin B12. Apart from that it also contains essential nutrients, and are a great source of fiber, folate (vitamin B9), manganese, potassium, iron, and vitamin C. You can have beetroots in cooked or boiled versions.
Basically, you'll get some of each essential vitamin in a banana – vitamin A; all the B vitamins except B-12; vitamin E; vitamin K; and choline. Bananas don't supply vitamin D, which, like B-12, is found primarily in animal foods.
Even through the soil itself, which sticks to the surface of the plant, people can consume B12 when eating some plant foods – for example, fresh carrots.
