B12 Injections for Energy and Weight Loss – Does it really work?

Do B12 shots work?

Vitamin B12 Shots Are very effective. Injections are very effective at raising blood levels of B12 and preventing/improving a deficiency. If you are deficient in vitamin B12, then the injections are extremely effective at raising your blood levels.

What are the benefits of taking vitamin B12?

Vitamin B12 is a nutrient that helps keep your body’s blood and nerve cells healthy and helps make DNA, the genetic material in all of your cells. Vitamin B12 also helps prevent anemia, a blood condition that makes people tired and weak.

It’s also been recently reported that B12 supplementation may affect the onset of Alzheimer’s disease for people who are B12 deficient.

How much vitamin B12 do I need?

The amount of vitamin B12 you need each day depends on your age. Average daily recommended amounts for different ages are listed below in micrograms (mcg):

Reasons for B12 deficiency

B vitamin complex supplement is often touted to boost energy levels and mood. People who have a B vitamin deficiency may feel a rise in energy levels after using the supplement because the vitamin is directly involved in making healthy blood cells and can correct anemia if present.

  • Avoiding animal products. People who do not eat meat, fish, poultry, or dairy are at risk of becoming deficient in vitamin B12, since it is only found naturally in animal products. For this reason, those who follow a vegetarian or vegan diet should include B12-fortified foods or a B12 supplement in their diets.
  • Body unable to absorb it. Pernicious anemia is an autoimmune disease that attacks and potentially destroys gut cells so that intrinsic factor is not present, which is crucial for vitamin B12 to be absorbed.
  • Inadequate stomach acid or medications that cause decreased stomach acid. A much more common cause of B12 deficiency, especially in older people, is a lack of stomach acid, because stomach acid is needed to liberate vitamin B12 from food.
  • Intestinal surgeries or digestive disorders. Surgeries that affect the stomach can increase the risk of a deficiency. Certain diseases including Crohn’s and celiac disease that negatively impact the digestive tract also increase the risk of deficiency.

B12 supplements vs shots

Low B12 can cause anemia and fatigue. For many people with low B12 levels, a daily supplement in the form of a pill is as effective as taking a monthly muscle injection. The choice of shot or pill depends on the reason for the deficiency.

A disadvantage with oral vitamin B12 supplements is the need to take the vitamin on a daily basis, whereas B12 injections can often be administered once a week or once a month.

B12 injections are perfect for those who have trouble forgetting to take their medications on a daily basis.

Injections are also recommended for people with severe vitamin B12 deficiency. Injections work more quickly than tablets and are easily absorbed through the bloodstream.

Are B12 injections for energy and weight loss recommended for everyone?

There’s no solid evidence that vitamin B-12 injections aid weight loss.

Vitamin B-12 is a water-soluble B complex vitamin found naturally in a variety of foods, including meat, fish, and dairy products.

Vitamin B-12 is also added to some foods and is available as a dietary supplement. Vitamin B-12 injections are commonly prescribed to help prevent or treat pernicious anemia and B-12 deficiency.

Some weight-loss clinics offer vitamin B-12 injections as part of their weight-loss programs. Proponents of vitamin B-12 injections say the shots give you more energy and boost your metabolism, helping you shed unwanted pounds.

But unless you have a vitamin B-12 deficiency, vitamin B-12 injections aren’t likely to give you an energy boost.
