What is Vitamin B12?

Vitamin B12 is a water-soluble vitamin that plays an important role in red blood cell formation, cell metabolism, nerve function, and even the production of DNA. Few people know that this is one of the most common nutrient deficiencies in the world. Like most vitamins, B12 is not made by the body and must be consumed through foods or supplementation. According to the National Institute of Health, Office of Dietary Supplements, we should be getting about 2.4 mcg of vitamin B12 a day. Unfortunately, about 20% of the population is not getting an adequate amount of B12 in their diets.

What is Vitamin B12 and why is it so important?

As mentioned earlier, Vitamin B12 is a water-soluble vitamin that plays an important role in red blood cell formation, cell metabolism, nerve function, and the production of DNA. Our bodies use red blood cells to transport oxygen to the body’s tissues in exchange for carbon dioxide, which is then eliminated by the lungs during exhalation. It is the key vitamin that helps prevent megaloblastic anemia, which makes individuals tired and weak.

In London, who does Vitamin B12 deficiency affect?

Vitamin B12 deficiency is often common amongst:

  • older adults who do not have enough hydrochloric acid in their stomach to absorb Vitamin B12 naturally;
  • individuals who take stomach acid-altering medications or antibiotics frequently;
  •  those who have gastrointestinal conditions, vegetarians/ vegans, and individuals with pernicious anemia.
  • Monthly vitamin B12 injection can benefit not only these at-risk populations but all individuals regardless of if you are deficient or not.


Signs of Vitamin B12 deficiency?

If you are lacking Vitamin B12 then you can have a blood test or spot signs of deficiency. This is important because B12 deficiency can lead to side effects such as:

Feeling constantly fatigued, feeling weak, anemia. As well as in severe cases can lead to strange sensations, numbness, tingling in the hands or feet, difficulty walking, and memory loss.


How do we naturally get Vitamin B12?

Vitamin B12 is naturally found in animal products such as fish, meat, poultry, eggs, milk, and other dairy products. You can also find vitamin B12 in fortified cereals and nutritional yeast products. Unfortunately, we are only able to get a small amount of B12 orally.


Are there any side effects to Vitamin B12?

Vitamin B12 injections are considered very safe with very little to no known adverse side effects and low potential for toxicity. In rare cases, people have experienced side effects associated with allergic reactions or sensitivity. Vitamin B12 does have the potential to react with certain medications including chloramphenicol, proton pump inhibitors, H2 receptor antagonists, and Metformin. It is important to discuss with your practitioner if you are taking any of these medications prior to taking Vitamin B12 injections.

Additionally, you can consider B12 shots if you are experiencing fatigue, a low immune system, or not feeling rested throughout the day even after sleeping.


Why is Vitamin B12 Injection better than Oral supplementation?

An Intramuscular Injection (IM) of Vitamin is better because the injection bypasses the digestive system. It allows for 100% absorption through the bloodstream. Why get 56% absorption with oral supplementation, when you can receive 100% absorption of Vitamin B12?


How often can I get Vitamin B12 injections?

Vitamin B12 injections are usually given once a month. As said, Vitamin B12 plays a key role in red blood cell formation. Millions of red blood cells are being made and dying off daily and the body builds up stores within the body.  With millions of red blood cells being produced daily, it is imperative that we get an adequate amount of vitamin B12.
