Vitamin injections are taking a new spin on the idea of taking your vitamins, and even have added benefits to taking a simple multivitamin. 

Vitamin B injections are a nutraceutical option, which just describes a substance that offers health benefits. Vitamin B injections are right for many people and may help support your health in many ways. 

Keep reading to learn more about what vitamin B injections are, their benefits, if they are safe, and if they could be right for you. 

What is Vitamin B?

Before diving into the injection part, it is important to understand the basics of what B complex injections are. The B vitamins include eight different vitamins that have varying roles in the body. All eight B vitamins are essential in keeping the body working properly. 

Many of the B vitamins are taken in by foods, but, depending on your diet, you may not be getting enough of these vitamins. 

The B vitamins include:

  • B1 (thiamine)
  • B2 (riboflavin)
  • B3 (niacin)
  • B5 (pantothenic acid)
  • B6 (pyridoxine)
  • B7 (biotin)
  • B9 (folic acid)
  • B12 (cobalamin). 

The function of each B vitamin may help in different areas of the body.

What Are Vitamin B Injections?

Vitamin injections are just as they sound. They are a shot of B vitamins into your muscle. A B vitamin injection that you get at one place may be different from one at another. Different clinics may use different rations and combinations of B vitamins to personalized the injection for your specific goals. 

B12, B1, B6, and B2 are some of the most popular B vitamins to be included in B vitamin injections.  

You may be wondering why you would choose to get a vitamin injection when you could take a vitamin supplement instead. A supplement may be easier to take by mouth, but the vitamin has to be digested through the digestive tract, and some of the vitamins may be lost if it is not appropriately absorbed.  

Alternatively, with intramuscular injections, you do not have to worry about absorption through the digestive tract, as it is instead going directly into the muscle. It is then absorbed into the blood supply to get the vitamin into the body more quickly and at a higher concentration. This is another reason that vitamin B12 injections and other B complex shots are so useful—while you can get some B vitamins from your diet from dairy products, breakfast cereals, and fish like salmon or trout, injections are a much more efficient form of vitamin B12 and other B complex vitamins. 

There are multiple names for vitamin B12 shots and other vitamin B injections, including hydroxocobalamin or cyanocobalamin. These two are the most commonly administered vitamin B shots.

What Are the Benefits of Vitamin B Injections?

The benefits you get from a vitamin B injection will vary from the B vitamin(s) that are inside of the injection. But overall, you can expect to see overall health benefits, which can include boosting mood, supporting weight loss, supporting bone health, and maintaining brain health. 

If you are hoping to get a certain health benefit from your vitamin B injection, you can ask your healthcare provider which vitamin may be best to help you reach your goals.

Can Correct a B12 Deficiency

A B12 deficiency is one of the most common reasons for getting vitamin B injections. People with a B12 deficiency often cannot absorb B12 through their digestive tract, so they must receive it in injection form. 

B12 is so important to the body because it plays an important role in energy production as well as creating red blood cells, which are vital in carrying oxygen around the body. Without enough B12, there is an increased risk of developing a type of anemia called pernicious anemia. Most people do not have a true B12 deficiency; however, if you do, then B12 injections will likely be recommended by your healthcare provider. 

A B12 shot is also a great way for vegans and vegetarians to supplement their diets, as most B12 in food is bound to animal-based protein molecules. People who don’t eat animal products are more likely to experience a vitamin B12 deficiency, which can lead to fatigue, headache, irritability, a swelling tongue, and reduced cognitive function, among other symptoms.

Can Boost Mood

Vitamin B injections may also help boost your mood. The exact way in which B12 can boost mood is not fully understood, but there may be a connection to its role with serotonin. 

Serotonin is a neurotransmitter involved in mood and appetite, as its main role is helping to balance many processes within the body. This is helpful in boosting mood if your levels of B12 are low. 

B12 is often found in foods like meat, fish, milk, cheese, and eggs, so if you do not eat a diet high in animal products you may have a lower level of B12. 

Can Support Weight Loss

Vitamin B injections can also support your weight loss goals. This may not be directly related to burning the fat off you, but it may help to boost your energy so you can get in your workout for the day. Oftentimes, half of the battle of exercising is feeling like you don’t have the energy to do it. With an extra boost from vitamin B injections, you could get what you need to get over the hump. 

The vitamins may also help to boost your metabolism so your body can burn calories more efficiently to help you reach your goals. You should know that these are not a magic weight loss injection. Instead, they may help you to reach your goals more easily in combination with all of your hard work. 

Can Support Bone Health

Vitamins and minerals are vital in supporting healthy bones and preventing weakening from occurring. You’ve probably heard of drinking your milk as a child to protect your bones, but did you know that taking your B12 can also help to support your bone health as well? 

B12 plays a role in strengthening bones and keeping them healthy. It has actually been found that people with low levels of B12 can develop a weakening of the bones, which can make them more prone to bone breaks and other bone issues. 

So, next time you are drinking your glass of milk, consider if you have taken your B vitamins as well!

Can Support Brain Health

The brain is arguably one of the most important organs in the body. It is responsible for regulating our body functions, so keeping it healthy should be a top priority. 

Vitamin B12 may help to support brain health in more ways than one. Low levels of vitamin B12 have been associated with certain brain conditions that can impact memory and cognitive performance. Vitamin B12 can also help to support memory in those with normal levels of B12 as well. 

Are Vitamin B injections Safe?

 Since vitamin B is something that you regularly intake via your diet, you will rarely have unwanted side effects from a vitamin B injection. So yes, vitamin B injections are generally safe. 

Some people may have an allergic reaction to vitamin B injections (or the mineral cobalt, which is present in all forms of vitamin B12) just like you may have to any other food or medication. If you begin to have hives, breathing difficulties, or any other severe symptoms, seek immediate medical attention. 

Otherwise, some of the non-severe symptoms may include mild diarrhea, headache, stuffy nose, and nausea. 

Are Vitamin B Injections Right For You?

If vitamin B injections are right for you is a question that only you and your healthcare provider can answer together after discussing health history, possible benefits, and possible risks. 

However, some things could indicate that vitamin B injections may be helpful for you. Vitamin B injections can be helpful for many people, but they will be most helpful for people that have low levels of vitamin B due to their diet, or if they have trouble absorbing vitamin B.  

If you have a diet that is low in meat products or dairy, you may benefit more from a vitamin B injection. Also, some B vitamins can be difficult to get through your diet, so a vitamin B injection may be a good alternative to taking a supplement in a pill form. 

If you feel like you could benefit from any of the benefits listed in this article you may want to bring it up with your health care provider to see if a vitamin B injection may be right for you.

Always consult with a healthcare provider to determine whether any other medication or treatment is safe for you to use. 


Vitamin B injections can offer a quick way to get vitamin B into your system. Vitamin B injections have many health benefits, including boosting mood, supporting bone health, supporting brain health, and supporting blood health. 

Vitamin B injections have been used for many years for people with vitamin B deficiency, but the effects may be able to help those who simply have low levels of vitamin B in their system and they’re looking for an extra boost of vitamins.
