What Is Vitamin B12 And What Does It Do
Vitamin B12 is a water-soluble vitamin, also known as cobalamin.
It plays a vital role in brain function and the production of DNA and red blood cells.
Chemically, vitamin B12 can exist in a number of different forms, but all of them contain the mineral cobalt.
The vitamin can be stored in the liver for a long time, so it may take a few years for a deficiency to develop .
Vitamin B12 is a water-soluble vitamin that plays an important role in brain function and red blood cell production.
Many People Are Deficient
The recommended daily intake of vitamin B12 is 6 micrograms per day.
Deficiency is common, especially in people who follow a vegetarian or vegan diet.
In fact, its thought that up to 90% of people following these diets have a deficiency .
This is because B12 is only found naturally in animal foods.
However, vegans and vegetarians are not the only ones who are deficient. Even some meat eaters dont absorb it very well .
Unlike other vitamins, the absorption of vitamin B12 depends on a protein produced in your stomach, called intrinsic factor.
Intrinsic factor binds to vitamin B12, so that you can absorb it into the blood. People who dont produce enough intrinsic factor can become deficient.
Deficiency is particularly common in elderly people, because the ability to absorb vitamin B12 can decrease with age .
Other people at risk of deficiency include those who have had intestinal surgery, including weight loss surgery. Those with diseases that affect the gut, such as Crohns disease or celiac disease, are also at risk .
Those at greatest risk of vitamin B12 deficiency are vegans and vegetarians, who get little to no B12 from the diet. Deficiency can also be caused by poor absorption.

Is There A Maximum Amount And Frequency Of Vitamin B12 Injections
While you should be careful how much vitamin B12 you inject and should discuss appropriate dosage and frequency for you with a trusted healthcare professional, it is practically impossible to have too much B12. There is no recommended maximum. Vitamin B12 is a very safe supplement that can be injected as frequent as once a day, although you may want to take more or less depending on you, your health, your age, and your lifestyle.
Other Ways To Get Vitamin B12
Vitamin B12 is found in animal foods, as well as some fortified foods that have added B12.
Fortified foods vary from country to country, but often include milk alternatives or breakfast cereals.
Some especially good sources of vitamin B12 include:
- Liver: 1/3 cup provides 881% of the RDI.
- Beef kidney: 1/3 cup provides 311% of the RDI.
- Trout: 1/3 cup provides 61% of the RDI.
- Canned salmon: 1/3 cup provides 61% of the RDI.
- Ground beef: 1/3 cup provides 40% of the RDI.
- Eggs: 2 large eggs provide 25% of the RDI.
- Milk: 1 cup provides 20% of the RDI.
- Chicken: 1/3 cup provides 3% of the RDI.
It can be difficult for some people to meet their vitamin B12 requirements. This is particularly true for those following a vegetarian or vegan diet.
In these situations, its usually recommended that you supplement your diet with either a B12 shot or oral supplement.
Fortunately, there is increasing evidence that oral B12 supplements are just as good as injections for raising blood levels in most people .
Vegetarians and vegans are usually advised to take at least 10 mcg per day, or at least 2,000 mcg once per week.
However, some doctors still prefer the use of injections.
Many animal foods are high in vitamin B12. Oral supplements have also been shown to be effective at raising blood levels.

Why Do We Need To Get Vitamin B12 Shots
Untreated vitamin B12 deficiencies can lead to neurological issues or pernicious anemia which can occur when your body does not have enough vitamin B12 to produce the amount of red blood cells it needs.
Vitamin B12 injections are the most common and effective way to prevent and treat a deficiency. The injections are prescribed by a medical provider and given intramuscularly, or into the muscle.
Injections are very effective at raising blood levels of vitamin B12 and preventing or reversing a B12 deficiency. We serve patients from West Moore OK, Tecumseh OK, Norman OK, Norman OK, Edmond OK, I-240 & Sooner RD OK, Yukon OK, and Bethany OK.
Combining B12 With Lipotropic Nutrients
There are several vitamin B12 injection sites and a few different types of vitamin B12 injections. Most injections just contain vitamin B12, though more and more people are choosing to buy lipotropic injections to supplement weight-loss programs. Lipotropic injections contain amino acids in addition to B12, which work in tandem to speed up the metabolism and thus assist in weight-loss efforts.

Effects Of B12 On Metabolism And Fat
Despite the limited research on B12 in human beings, many studies suggest that vitamin B12 could affect metabolism and body fat.
B12 plays a crucial role in fat metabolism. A deficiency could be associated with obesity and heightened fat accumulation. An animal study revealed that severe vitamin B12 deficiency led to a considerable increase in cholesterol levels and body fat percentage in pregnant mice.
Another study found that giving B12 vitamins to rats with a high-fat diet lowered weight gain and boosted levels of different enzymes that affect metabolism.
Interestingly, different studies have revealed that an adequate vitamin B12 level is associated with lower risks of obesity and weight gain. Based on research done on 9,075 people, having higher vitamin B12 levels was linked to lower risks of obesity.
Similarly, a study on 256 children showed that those with lower B12 levels tended to have a bigger BMI , which measures body size based on weight and height.
However, remember that while these studies reveal a link between body weight and vitamin B12 status, no other potentially contributing factors are considered. Thus, its impossible to assume that B12 leads to weight loss. Further research needs to be done to ascertain that B12 affects BMI or body weight.
Are There Any Side Effects Of A Vitamin B12 Shot
Generally, side effects are rare, although there are a few mild side effects that you may experience with the B12 shots, including pain, bruising or redness at the B12 injection site, mild diarrhea, itching, or swelling. While these symptoms are usually nothing to worry about, if they persist or worsen, you are advised to contact your health care professional.

An intradermal test dose is recommended before vitamin B12 is administered to patients who may be sensitive to cobalamins.Hypokalaemia and cardiac arrest have been reported when megaloblastic anaemia is treated intensively.Serum potassium is to be carefully monitored during the initial phase of treatment in pernicious anaemia.Diagnosis of vitamin B12 deficiency should be confirmed by laboratory investigation before institution of hydroxocobalamin therapy. Do not use hydroxocobalamin until diagnosis is fully established, as it may mask symptoms of subacute degeneration of the spinal cord, or of the true diagnosis of pernicious anaemia. Folic acid may potentiate the neurological complications of vitamin B12 deficiency, so should not be administered to patients with pernicious anaemia .Regular blood tests to determine vitamin B12 levels are advisable during treatment.Administration of hydroxocobalamin doses in excess of 10 microgram daily may improve folate deficient megaloblastic anaemia and obscure the true diagnosis.The therapeutic response to hydroxocobalamin may be impaired by concurrent infection, uraemia, folic acid or iron deficiency, or by drugs with bone marrow suppressing effects, such as chloramphenicol .Treatment with hydroxocobalamin may unmask polycythaemia vera, because vitamin B12 deficiency may suppress the symptoms of this condition.

On the other hand, it is also essential to receive that maximum boost needed from these injections. Here are some of the benefits you may get from B-12 injections.
1. It balances or increases our metabolism.
Metabolism sustains life through groups of chemical reactions in our cells. Vitamin B-12 plays a vital role in our metabolism. Efficient metabolism can be noticeable in how quickly we burn the food we eat. These reactions usually dont occur at slower rates. If so, our body functions become slower, too. This slow down can result in weight gain and fatigue. A balanced B-12 level can boost our metabolism, helping our bodies function better.
2. It prevents anemia by increasing red blood cells.
B-12 injections provide the critical vitamin our body needs in creating new red blood cells. Red blood cells are in-charge in transporting oxygen and other nutrients throughout the other cells of the body. Having a low count of red blood cells can make you experience anemia that causes our bodies to feel fatigued. Additionally, B-12 deficiency may also result in lightheadedness and dizziness. Ample amounts of vitamin B-12 prevent anemia and help our bodies have enough red blood cell production, causing that needed boost in our energy.
3. It keeps the brain healthy.
