Vitamin B12 is a nutrient that helps keep the body's nerve and blood cells healthy and helps make DNA, the genetic material in all cells. Vitamin B12 also helps prevent a type of anemia called megaloblastic anemia that makes people tired and weak. Two steps are required for the body to absorb vitamin B12 from food.

Vitamin B12 Content of Some Common Foods. The best sources of Vitamin B12 include: eggs, milk, cheese, milk products, meat, fish, shellfish and poultry. Some soy and rice beverages as well as soy based meat substitutes are fortified with vitamin B12.
Cyanocobalamin is a man-made form of vitamin B12 used to treat low levels (deficiency) of this vitamin. Vitamin B12 helps your body use fat and carbohydrates for energy and make new protein. It is also important for normal blood, cells, and nerves.
Vitamin D (ergocalciferol-D2, cholecalciferol-D3, alfacalcidol) is a fat-soluble vitamin that helps your body absorb calcium and phosphorus. Vitamin D is used to treat and prevent bone disorders (such as rickets, osteomalacia). Vitamin D is made by the body when skin is exposed to sunlight.
Vitamin B-12, or cobalamin, is a nutrient you need for good health. It's one of eight B vitamins that help the body convert the food you eat into glucose, which gives you energy. Vitamin B-12 has a number of additional functions.
Vitamin C, also known as ascorbic acid, is a water-soluble nutrient found in some foods. In the body, it acts as an antioxidant, helping to protect cells from the damage caused by free radicals. Free radicals are compounds formed when our bodies convert the food we eat into energy.
Omega-3 fish oil contains both docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Omega-3 fatty acids are essential nutrients that are important in preventing and managing heart disease. Findings show omega-3 fatty acids may help to: Lower blood pressure.
Vitamin B-12 can cause the following side effects:
- restenosis (reoccurrence of narrowing of a blood vessel) after stent placement.
- high blood pressure.
- itchy or burning skin.
- pink or red skin discoloration.

- urine discoloration.
B12 and weight loss. Recently, vitamin B12 has been linked to weight loss and energy boosts, but are these claims for real? B12 deficiency can lead to several ailments, most notably megaloblastic anemia, which is caused by a low red blood cell count. The most common symptom of megaloblastic anemia is fatigue.
Vitamin B2 helps break down proteins, fats, and carbohydrates. It plays a vital role in maintaining the body's energy supply. Riboflavin helps convert carbohydrates into adenosine triphosphate (ATP). The human body produces ATP from food, and ATP produces energy as the body requires it.
The answer: Vitamin B12 is found naturally only in animal foods including meat, chicken, fish, eggs and dairy. If it's only red meat you avoid – or red meat and poultry – you can still get B12 by drinking milk and eating yogurt and eggs. As a comparison, three ounces of lean beef has 2.8 mcg of vitamin B12.
If necessary this treatment is repeated within several hours, making the total dose 10 grams. The side effects that occur, like reddening of the skin and urine and changes in heart rate and blood pressure are temporary and harmless. In short: 10 000 injections a day are still not enough for an overdose of vitamin B12.
But if untreated, it may lead to symptoms such as:
- Weakness, tiredness, or lightheadedness.
- Heart palpitations and shortness of breath.
- Pale skin.
- A smooth tongue.
- Constipation, diarrhea, loss of appetite, or gas.
- Nerve problems like numbness or tingling, muscle weakness, and problems walking.
- Vision loss.
The AAP also recommends 400 IU/day of vitamin D for children and teens who drink less than a quart of vitamin D-fortified milk per day. The Vitamin D Council recommends that healthy adults take 2,000 IU of vitamin D daily -- more if they get little or no sun exposure.
Eggs. Eggs contain 0.89 micrograms of vitamin B-12 per 100 grams, or 15 percent of the daily value of 6 micrograms. Each large egg contains 0.44 micrograms of vitamin B-12, or 7 percent of the DV. This makes eggs the most concentrated source of vitamin B-12 by weight when compared to milk and chicken.
Niacin, also known as vitamin B3, is an important nutrient. In fact, every part of your body needs it to function properly. As a supplement, niacin may help lower cholesterol, ease arthritis and boost brain function, among other benefits. However, it can also cause serious side effects if you take large doses.
Values of less than 200 pg/mL are a possible sign of a vitamin B12 deficiency. Older adults with vitamin B12 levels between 200 and 500 pg/mL may also have symptoms. Deficiency should be confirmed by checking the level of a substance in the blood called methylmalonic acid. A high level indicates a true B12 deficiency.
Iron is an important component of hemoglobin, the substance in red blood cells that carries oxygen from your lungs to transport it throughout your body. Hemoglobin represents about two-thirds of the body's iron. A lack of red blood cells is called iron deficiency anemia.
Food. Vitamin B12 is naturally found in animal products, including fish, meat, poultry, eggs, milk, and milk products. Vitamin B12 is generally not present in plant foods, but fortified breakfast cereals are a readily available source of vitamin B12 with high bioavailability for vegetarians [5,13-15].
