Vitamin injections and medications have increasingly become popular, and people use these supplements to ensure that the body has enough supply to stay healthy. Vitamin injections are not new, and it is frequently used in the medical community to address vitamin deficiency. One particular vitamin injection that is the most popular is the vitamin B12 injection

Why Vitamin B12 Injections Are Widely Spread

 Vitamin B12 deficiency is one of the most common nutritional deficiencies. If left untreated, it can cause irreversible damage to the brain, spinal cord, heart, and other organs. Vitamin B12 deficiency can occur due to many reasons, mainly improper diet or you have a condition where your body can’t absorb as much. 

Vitamin B12 is an essential nutrient, and those that have that are deficient in this vitamin would need vitamin B12 injections every couple of months. This injection is necessary for the body, not just to prevent some minor symptoms. However, there is another popular reason why most people use vitamin B12 injection, and that is to help them lose weight. 

Many blogs and comments online swear that vitamin B12 injections help them lose weight. But are any of these claims true? To find out, we have to illustrate to you what is vitamin B12 injection and see how it may affect you if you use it. 

What Is Vitamin B12?

Vitamin B12 is a water-soluble vitamin with a molecular weight of 192.4 Daltons that is essential in the body for cell division and DNA synthesis. Vitamin B12 is also needed for the regular functioning of cells and the production of DNA and RNA, particularly in rapidly dividing cells. It is also crucial for healthy nerves and good brain function.

Doctors and nutritionists alike recommended dietary allowance (RDA) for vitamin B12 is 2.4 micrograms per day for adults aged 19 years or older. If you are over age 50, you should aim to eat around 3-5 micrograms per day, while pregnant or breastfeeding women should consume 2-3 micrograms a day.

What Foods Contain Vitamin B12?

Despite being a water-soluble vitamin, you can only obtain this vitamin primarily through animal foods like meat, milk, and eggs. This means that vegetarians are at risk of low vitamin B12 due to poor food choices or inadequate intake of supplements alone.

However, if you are a vegetarian and vegan, you may be interested in trying out other sources of vitamin B12, such as nori, shitake mushroom, and fortified foods. Vitamin B12 supplements can also be used if necessary. Nutritional yeast is another option that provides many nutrients for vegans.

Many Are Unknowingly Are Vitamin B12 Deficient

In the United States, about 6% of adults ages 60 and below are deficient in vitamin B12. This means that 6% of the population has a deficiency symptom. There are many different symptoms of vitamin B12 deficiency, but not all of them are visible or easily detectable. Some symptoms may not show up for a few years until the deficiency worsens and affects other parts of your body.

If you are a vegetarian or vegan, knowing that you are at risk for B12 deficiency is essential. Recent estimates have shown that 90% of people who follow a strict vegan or vegetarian diet are vitamin B12 deficient. So before you try a vegan or vegetarian diet, make sure that you consult with a doctor first before proceeding. 

Most people do not notice that the body can store Vitamin B12 in the liver for several years. Once the vitamin B12 storage is exhausted, the symptoms creep in, but the affected person won’t notice the subtle changes. Likewise, symptoms of vitamin B12 can also resemble anemia or fatigue, causing some people to think that they are simply tired.

Both vegans and vegetarians have to be proactive to ensure that they won’t experience vitamin B12 deficiency. 

Symptoms Of Vitamin B12 Deficiency 

If you aren’t sure if you are deficient in vitamin B12 or not, make sure that you check the list down below:

  • Lightheadedness or dizziness
  • Discomfort and chest pain
  • Difficulty in thinking clearly and concentrating
  • Rapid breathing or shortness of breath
  • Fatigue
  • Pale Skin

If left untreated, vitamin B12 deficiency may cause long-term health problems. It can lead to anemia, neurological complications, and even death. 

How Vitamin B12 Injections Can Help You

If you have any of the symptoms above, perhaps you lack vitamin B12, and if that’s the case, you may need vitamin B12 injections. Once we restore the adequate supply of vitamin B12 in your system, it effectively erases the symptoms mentioned above. 

Not only does it erase the symptoms above, but it also has some additional benefits, including:

Reduces Depression

Vitamin B12 deficiency is a common issue that can cause depression. When you are deficient in vitamin B12, your body does not make enough red blood cells. Red blood cells carry oxygen to the brain and other organs, causing a lack of energy and depression without them.

Improves Brain Function

Vitamin B12 is required by the body to make red blood cells, which carry oxygen to the brain and other organs. It also aids in producing neurotransmitters, which are chemicals that help communicate between neurons in the brain, improving brain function.

Does It Help With Weight Loss?

Vitamin B12 injections are a popular choice for people who have trouble losing weight. They are injected into the body, which helps release energy and boost metabolism. There is also evidence that it increases noradrenaline levels in the brain, which helps with cognitive function and mood, energizing the use to do more.

However, vitamin B12 injection is by no means a standalone solution for losing weight. Vitamin B12 boosts energy levels and metabolism, but it will never work unless you do something about it, which is still proper diet and exercise. The extra boost of vitamin B12 will help with weight loss if taken along with a consistently healthy diet and exercise routine.


The vitamin B12 injection will cause you to be more excited to exercise but not actually do the work for you. This may be a big break if you are frequently discouraged by constantly exercising.
