Vitamin B12 Injections

Vitamin B12 is an energy-boosting vitamin that is also considered to be a useful aid in weight loss. It can be taken orally or intravenously as prescribed by a physician. It's what helps create our DNA and our red blood cells. MIC B12 injections combine methionine, inositol and choline and are used to strengthen the liver and burn fat, as well as improve energy levels.

B12 Shots are $35 a piece, but we require a $100 minimum for mobile services. Add this to your IV package or get a group of 3 or more people and we're happy to make the trip to you!

How Often Should I Get a B12 Shot?

Vitamin B12 injections are prescribed by doctors and cn be administered from one to three times a week. Because each person's body is different, B12 injections don't have the same effects on everyone.

Most humans have up to two years' worth of B12 stored in their livers. Others have diets that make it difficult to maintain healthy levels of B12, requiring them to seek out alternative sources, such as supplements and injections. Those with a B12 deficiency may be required to take B12 injections multiple times a week.

If you have been prescribed a B12 injection to aid weight loss, your doctor may suggest a weekly dose. 

What Are the Benefits of B12?

There are many benefits to B12 injections, including an increase in the creation of red blood cells — which are responsible for carrying oxygen through our tissues so it can be expelled as carbon dioxide.

But three of the most popular reasons for B12 injections are to improve energy levels, to support metabolism and to prevent anemia.

1. Improve Energy Levels

Generally, B12 is known to boost energy in those lacking it, and regular intake of B12 helps establish and maintain healthy energy levels.

If you're otherwise healthy but find yourself constantly fatigued, talk with a doctor about a potential B12 deficiency. B12 injections may be able to increase your energy levels by introducing more oxygen into the body. The oxygen is distributed through the bloodstream to major organs, increasing overall energy in the body.

However, the effects are likely only present in those who have a B12 deficiency. Those who have regular levels of B12 are unlikely to experience an energy boost from a B12 shot.

2. Support Metabolism

All the B vitamins are excellent at helping the body break down carbohydrates, fats and proteins. They're also important for maintaining a healthy metabolism, which is what does the breaking down of those three things.

Without adequate amounts of B12 — and any of the other B vitamins — the metabolism won't be able to do its job properly, which can make losing weight very hard.

3. Prevent Anemia

Pernicious anemia is a type of anemia in which your body is unable to absorb vitamin B12, which then prevents your body from being able to produce red blood cells.

Humans possess something called intrinsic factor, which is a protein the stomach creates to help the body absorb B12. However, some people's immune system mistakenly destroys the cells that create the intrinsic factor. Without it, the body cannot absorb B12, and the lack of the vitamin results in pernicious anemia.

B12 injections are useful to provide the body with the vitamins it needs to continue to create red blood cells.

What Are the Symptoms of B12 Deficiency?

Vitamin B12 deficiency is something that can happen to anyone, but it is especially prevalent in people aged 50 and older. As the body ages, it naturally begins to lose the ability to absorb B12, resulting in deficiencies of the B vitamin.

Those who maintain a vegan diet are also at high risk of developing a vitamin B12 deficiency since meats and other animal by-products are some of the best sources of B12.

Some of the more common symptoms of a B12 deficiency include:

  • Weakness and/or fatigue
  • Difficulty maintaining balance
  • Cognitive difficulties, like memory loss
  • Oral pain, especially a red or swollen tongue
  • Tingling or numbness, especially in fingertips
  • Distorted or blurred vision
  • Dizziness or shortness of breath

How Much B12 Do I Need?

The average adult should get 2.4 mcg of vitamin B12 a day to maintain healthy energy levels and metabolism. Because the body loses the ability to absorb B12 as it ages, the dosage increases the older we get. People who are pregnant or breastfeeding also require more than the average dosage, with 2.6 mcg being the recommendation.

Dosage is not something that can be self-prescribed. If you suspect that you aren't getting enough B12 and may need injections or supplements, talk with your doctor to find out how much you need.

Are There Side Effects to B12 Injections?

For the most part, B12 injections are very safe and have few side effects. There is no harm in taking large amounts of B12 as the body only uses what it needs and naturally expels any excess. 

After receiving a B12 injection, there may be some pain or redness at the injection site, and there is the possibility of mild diarrhea, itchiness and the feeling of swollen skin all over your body. However, there is only cause for concern if these symptoms persist.

Allergic reactions to B12 shots are very rare, but symptoms that require medical attention include a rash, itchiness or swelling in the face or mouth and dizziness.

How Else Can I Get Vitamin B12?

The best way to naturally get B12 is to eat foods that are rich with vitamin B. These include:

  • Shellfish
  • Eggs
  • Meat and poultry
  • Milk and milk products

While a well-rounded diet is an ideal way to ensure you're getting enough B12, those on a vegan diet can look to certain plant milk with B12 as well as nutritional yeast and fortified cereals. B12 supplements in pill form are also an option, the dosage of which your doctor can recommend.
