Vitamin B12 is a water-soluble vitamin that is essential for normal function of the brain and nervous system, formation of blood and DNA, and for the regulation of the body’s energy metabolism. In adults, about 2.4 micrograms (mcg or µg) of vitamin B12 are needed daily to replace amounts that are lost from the body; this amount increases to about 2.6 mcg for pregnant women and 3 mcg for breastfeeding women.
Vitamin B12 is produced by microbial fermentation and some types of soil bacteria. It is found in meat, eggs, and dairy products but not plant foods. Vitamin B12 can be destroyed by exposure to light, air and heat so it should be stored in airtight containers in the dark at room temperature or below [1].
Vitamin B12 is a water-soluble vitamin that is naturally found in animal products. It helps with red blood cell formation and nerve function. Vitamin B12 is also known as cobalamin and can be used to treat low levels of the vitamin.
Vitamin B12 is found in many foods, including milk, eggs and fish. Dry fruits like apricots, figs, dates, prunes and raisins are also good sources of vitamin B12. Eggs are one of the most easily digestible sources of vitamin B12 for vegetarians and vegans because they contain vitamin B12 in the yolk.
It is recommended that adults consume 2.4 micrograms (mcg) of vitamin B12 each day according to the National Institutes of Health (NIH).
Vitamin B12 is an essential vitamin required for a variety of functions in the body, including DNA synthesis and red blood cell formation. It also plays a role in energy metabolism and neurological function.
Bacteria make vitamin B12, so some people get their supply from food sources associated with bacterial contamination, such as unpasteurized milk, cheese and meat. Other people may not make enough intrinsic factor (a substance produced by the stomach) to absorb vitamin B12 from foods.
If you don’t get enough vitamin B12 from food, you may need to take a supplement or eat fortified foods that contain this nutrient.
Vitamin B12-Rich Foods
The richest sources of vitamin B 12 are animal products like meat, poultry, fish and dairy products. Some plant foods are also good sources of this vitamin if they’re contaminated with bacteria or were grown in soil fertilized with manure (another source of vitamin B 12 ). These include:
Clams
Eggs
Fish
Liver (beef or chicken)
Milk (cow’s milk)
Vitamin B12 is a water-soluble vitamin that helps in the production of red blood cells. It also promotes the body’s use of folic acid and is involved in protein metabolism.
Vitamin B12 is naturally found in fish, shellfish, meat, eggs and dairy products. However, vegetarians may need to take vitamin B12 supplements or eat fortified foods or nutritional yeast to make sure they get enough of this essential vitamin. Vitamin B12 deficiency can lead to anemia and other health problems.
Here are some foods that are good sources of vitamin B12:
Eggs – 1 large egg has 0.3 micrograms (mcg) of vitamin B12
Fish – 3 ounces of salmon contains 2 mcg; 3 ounces of sardines contains 2 mcg; 3 ounces of tuna contains 2 mcg
Milk & Yogurt – 1 cup of whole milk has 0.9 mcg; 1 cup or plain yogurt has 0.9 mcg
Vitamin B12 is a water-soluble vitamin that helps maintain the nervous system. It’s also needed to make DNA and red blood cells. Vitamin B12 is naturally present in some foods, added to others, and available as a dietary supplement.
Vitamin B12 deficiency is rare, but it can cause serious health problems. A vitamin B12 deficiency early in pregnancy may result in miscarriage or premature birth. Other symptoms include weakness, weight loss, and depression.
You should talk with your doctor about the best sources of vitamin B12 for you. You should also talk to your doctor before taking vitamin B12 supplements.
Vitamin B12, also called cobalamin, is a water-soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is one of the eight B vitamins. It contains the mineral cobalt (hence its name), and it is found in food such as meat, fish and dairy products.
Vitamin B12 deficiency can lead to a range of neurological symptoms, including tingling in the arms and legs (peripheral neuropathy), sensory loss and balance problems (dizziness). These symptoms may develop over time or suddenly if there are underlying conditions such as malabsorption or alcoholism.
Vitamin B12 deficiency can also cause anaemia because it helps produce red blood cells. In addition, the body needs it to make DNA, which is essential for building new cells.
People who have low levels of vitamin B12 may benefit from taking supplements or eating more food rich in this nutrient.
Vitamin B12 is a water-soluble vitamin that plays an essential role in a variety of metabolic functions, including DNA synthesis and regulation as well as fatty acid metabolism. It has also been shown to play an important role in the formation of red blood cells and neurological function.
Vitamin B12 deficiency can lead to a wide range of symptoms, including fatigue, weakness, depression, mood swings and confusion. As it occurs at a cellular level, vitamin B12 deficiency may not be immediately noticeable; instead, symptoms may take years to manifest themselves.
The best sources of vitamin B12 include:
Eggs (1 egg contains approximately 0.6 micrograms)
Fish (3 ounces of tuna contains approximately 1 microgram)
Dry fruits (1/2 cup of prunes or raisins contains approximately 0.9 micrograms)
Nuts and seeds (1/4 cup of almonds or walnuts contains 2-3 micrograms)
Nuts and seeds are an excellent source of vitamin B12. Many people have a problem getting enough vitamin B12 in their diet because it is not found in many foods. Nuts and seeds are also a good source of protein, unsaturated fat, magnesium and zinc.
In addition to being a great source of protein, nuts are packed with fiber and heart-healthy fats. The high fiber content helps keep you feeling full longer, which can help curb overeating throughout the day. The monounsaturated fats in nuts also help lower cholesterol levels.
Because nuts are high in calories, they should be eaten in moderation. A serving size is about 1 ounce (or 20 almonds), which contains 160 calories and 14 grams of fat (9 grams saturated).
Seeds are packed with nutrients like vitamin E, iron, zinc and selenium — which help protect your cells from free radicals that cause cell damage and disease. They’re also rich in fiber, which keeps you feeling full longer and may aid weight loss efforts by reducing hunger cravings between meals.
Sunflower seeds are one of the best sources of vitamin E among nuts and seeds — each serving provides 20 percent of your daily value for this nutrient! Vitamin E boosts immune system function
Vitamin B12 is a water-soluble vitamin that can be found in animal foods, fortified foods and dietary supplements. It’s essential for the normal functioning of all cells, especially nerve cells.
Vitamin B12 deficiency can lead to anemia and irreversible nerve damage.

Vitamin B12 is a water-soluble vitamin that plays an important role in the normal functioning of the brain and nervous system, as well as the formation of blood. It’s also important for the formation of red blood cells.
In addition to its water-soluble form, vitamin B12 also exists in a stored form called methylcobalamin. In order for you to get enough B12 through your diet, you must consume foods that contain both forms of this nutrient.
Vitamin B12 is naturally found in animal products such as fish, meat and poultry. However, some people don’t consume enough animal products to meet their needs for this nutrient. This is why it’s important to eat plenty of plant-based foods that contain vitamin B12 or take a supplement containing this nutrient if you fall into this category.
Below is a list of foods that are high in vitamin B12:
Vitamin B12 is the name for a group of B vitamins. There are a number of different forms of vitamin B12, and it can be found in both animal products and plant foods. Vitamin B12 is required to maintain healthy nerve cells as well as red blood cells.
Vitamin B12 deficiency can cause anemia, fatigue, weakness and tingling in the hands and feet. It can also lead to weight loss, shortness of breath and impaired mental function.
Vitamin B12 is found naturally in meat, poultry, fish, eggs and dairy products (although many people who don’t eat animal products or who follow vegan diets may need to supplement). Some types of algae are also sources of vitamin B12.
The best way to get enough vitamin B12 is by eating a variety of healthy foods each day. If you’re concerned about your diet or if you have trouble absorbing nutrients from food because of certain conditions (such as Crohn’s disease), talk with your doctor about whether you need to take supplements — especially if you are over age 50 or pregnant or breastfeeding.
