B12 Shot Side Effects – Do They Outweigh the Risk?
As vitamin B12 continues to gain popularity and attention, many are beginning to wonder what are the B12 shot side effects and benefits? Can this supplement really be as great as everyone keeps saying it is with no risks or side effects? While this treatment still fascinates us today and poses many questions, the history of the development of B12 shots is just as interesting.
In the 1850s, pernicious anemia was essentially a fatal condition – in today’s medicine pernicious anemia is easily treated with B12 supplements. However, in the 1850s patients suffered from abnormal gait, exhaustion, and inevitably they ended up in the hospital before they passed. It wasn’t until the 1920s when Georges Richard Minot and William Parry Murphy determined that certain foods (red meat and liver) were effective in treating anemia in dogs. Almost 50 years later, Robert Woodward, an organic chemist, was able to successfully synthesize vitamin B12. From this discovery, modern medicine was able to create treatments based on the discovery of vitamin B12’s role in anemia and the successful synthesis of its complex structure.
Thankfully, conditions caused by vitamin B12 deficiencies are incredibly treatable through vitamin B12 supplements. Understanding the B12 shot side effects and benefits can help you manage your expectations of vitamin B12 as a treatment, and also whether or not a B12 shot it the best form of treatment.
Vitamin B12 – What It is and What It Does
Vitamin B12, also known as cyanocobalamin, is an important factor in DNA synthesis, the metabolism of every cell within the body, the maturation of developing red blood cells, and the metabolism of fatty acids and amino acids. Because vitamin B12 is such an integral component in the function of a healthy body, maintain the proper levels of B12 within the body is absolutely necessary to sustain a properly working nervous system and a healthy red blood cell count.
Vitamin B12 is most commonly sourced through foods that come from animals such as fish, red meat, eggs, dairy, cheese, and other dairy products. Those who are vegan or vegetarian sometimes source their B12 through fortified cereals. While many people are able to consume and absorb the proper amount of vitamin B12 through their dietary choices, there are also many people who are not able to sustain the proper levels of B12 within their body, and this can lead to dangerous conditions if left untreated.
Vitamin B12 deficiencies are rare in otherwise healthy individuals; however, those at an elevated risk at groups who do not consume a diet with animal-sourced food, as well as those suffering from other health conditions. Groups at an increased risk of developing a vitamin B12 deficiency, are:
- Adults over 50
- Those with low gastric intrinsic factor
- Those with a low amount of stomach acid
- Those taking certain medications
- Gastrointestinal disorders like Crohn’s disease and celiac disease
- Those who have had weight loss surgery, bowel resection, or surgery on another part of the digestive tract
- Those who take metformin and acid-reducing medications
- Those with specific genetic mutations, such as MTHFR, MTRR, and CBS
- Those who regularly consume alcoholic beverages
If someone fits into one of these at-risk groups, it is best to consult your doctor in considering whether or not you should undergo testing to determine if you have a vitamin B12 deficiency. Presently, there is no one test that determines whether or not someone is deficient in vitamin B12, doctors must consider both lab results and clinical conditions to reach a diagnosis.
Symptoms of B12 Deficiency
Before considering both the B12 shot side effects and the B12 shot benefits, it important to understand what are the symptoms of a vitamin B12 deficiency. Individuals cannot procure vitamin B12 without a prescription, and in order to obtain a prescription, you must be deemed deficient. It can be especially tricky to reach this diagnosis as there is no “gold-standard” test, and symptoms can long go unnoticed or be contributed to other causes.
Consider that vitamin B12 is responsible for so many bodily functions, the displayed symptoms and affected body systems can vary greatly. Another problem is that symptoms and their onset tend to increase gradually, again making it hard to connect the dots between symptoms and cause. Listed below are just a few of the symptoms caused by a vitamin B12 deficiency:

Treatment for Vitamin B12 Deficiency
Fortunately, there are many options in modern medicine to safely and successfully treat a vitamin B12 deficiency. There are three main methods of treatment – a change in diet, oral supplements, and vitamin B12 injections. For those who aren’t receiving enough vitamin B12 as a result of food choices may be able to treat their deficiency by incorporating more vitamin B12 rich foods in their diets.
However, for those deficient as a result of age, a genetic mutation, stomach issues, or those taking certain medications, a change in diet may not be enough to treat a vitamin B12 deficiency. Likely, these individuals will have to supplement their diet with an oral B12 supplement or a B12 injection. Oral supplements are considered inferior to the vitamin B12 injections as they take longer to absorb, and some of the nutritional value is lost during digestion in the stomach.
For those receiving B12 shots as a treatment to a B12 deficiency, there are a few different forms, or vitamers, of synthesized vitamin B12 that can be used to handle the deficiency. These include:
- Cyanocobalamin – This vitamer is used for food fortification, multi-vitamin products, and dietary supplements. Cyanocobalamin is suitable for these methods of treatment because of its stability during processing and storage.
- Hydroxocobalamin – This vitamer is typically found within the pharmacology. Due to its water solubility, it is commonly used for intramuscular or intravenous injections. Also used to reverse the effects of cyanide poisoning, this vitamer is the preferred course of treatment for those with intrinsic cobalamin metabolic disease and those with optic neuropathy as a symptom of pernicious anemia.
- Adenosylcobalamin – This vitamer is an active cofactor form of vitamin B12. It naturally occurs in the liver and is active in the mitochondria.
- Methylcobalamin – This vitamer is an active form of B12 that works with several enzymes to create amino acids, produce red blood cells, repair DNA, and assist with other essential physiological processes. This form of B12 is typically administered through injections and oral supplements.
Determining the right course of treatment for a vitamin B12 deficiency is between the patient and their healthcare provider. Above all, the most important thing is that the deficiency is properly treated, treatment is working well, and the quality of the patient’s life is improving.

Are Vitamin B12 Shots More Effective Than Vitamin B12 Oral Supplements?
Both methods of treatment can deliver the desired results, and the majority of the “success” of treatment is determined on a case-by-case basis and what is most comfortable and effective for the individual patient. Some studies have shown that a high-dose, oral vitamin B12 was as effective as an intramuscular injection; however, other studies have determined that oral B12 supplements aren’t as fully absorbed during the digestive process.
