You should get B12 injections if diagnosed with a deficiency, especially if you have absorption issues from conditions like Crohn's, celiac disease, gastric surgery, or are a strict vegan/vegetarian, as injections bypass gut absorption problems, effectively raising levels for energy and to prevent neurological issues. Oral supplements are often sufficient if your deficiency stems from diet, but injections are key when the gut can't absorb B12, providing direct delivery for fatigue, anemia, or nerve symptoms.
Common side effects
Your doctor likely stopped B12 injections due to following standard guidelines suggesting oral supplements or for reasons like cost/logistics (especially during the pandemic), but this can be risky; the main reasons are often a perceived 'normal' blood test (which doesn't always reflect cell levels) or a guideline shift, but you may still need injections for neurological symptoms or poor absorption, so discuss your symptoms urgently with your doctor and ask for clear evidence for the change.
People who are deficient in vitamin B12 are often prescribed B12 shots. This method is a very effective way of reversing or preventing a deficiency because it allows for 100% absorption directly into the tissues.
For pregnancy, Vitamin B12 (like cyanocobalamin or hydroxocobalamin) is crucial for fetal brain/nerve development, especially for vegans/vegetarians; most get enough from animal products, but supplements (oral or injections for deficiency) are recommended if dietary intake is low, with doctors advising specific forms and dosages to prevent anemia and neural tube defects, so always consult your healthcare provider.
If you're pregnant, not having enough vitamin B12 can increase the risk of your baby developing a serious birth defect known as a neural tube defect.
Vitamin B12 deficiency symptoms develop gradually and include extreme fatigue, pale skin, shortness of breath, headaches, and nerve issues like numbness or tingling in hands/feet, plus cognitive problems such as memory loss and confusion, often linked to anemia but also affecting nerves and brain function, requiring medical diagnosis and treatment.
Vitamin B12 or folate deficiency anaemia can cause a wide range of symptoms. These usually develop gradually, but can worsen if the condition goes untreated.
In fact, some studies have even suggested the opposite. For instance, one study noted that individuals who regularly took vitamin B12 supplements gained between 2.5 to 17 fewer pounds (1.2 to 7.7 kg) over a decade than those who didn't supplement.
That's because B12 helps regulate serotonin and dopamine—the neurotransmitters responsible for keeping you happy and balanced. Regular B12 shots can help: Reduce stress and anxiety. Boost mood and emotional stability.
Oral vitamin B12 replacement at 1000 μg daily is an adequate alternative to IM B12 injections.
Vitamin B12 is abundant in animal products like meat (especially liver), fish (salmon, tuna, sardines), poultry, eggs, and dairy (milk, yogurt, cheese), with fortified foods such as cereals, nutritional yeast, and plant milks offering options for vegetarians and vegans, as plants don't naturally contain B12.
Causes of Vitamin B12 deficiency
People with very low vitamin B-12 levels can have symptoms such as fatigue, muscle weakness, stomach problems, nerve damage, vision problems and mood changes. They also may have low iron, called anemia, or low blood counts. The recommended daily amount of vitamin B-12 for adults is 2.4 micrograms (mcg).
To make sure it's safe for you, tell your doctor before having hydroxocobalamin if you:

Strengthens Hair Follicles to Promote Growth
This vitamin supports the production of keratin, the protein that makes up hair strands, helping them grow thicker and more resilient. When your body lacks B12, hair follicles may become weaker, leading to slower growth and thinning hair.
In conclusion, our results show that lower vitamin B12 was associated with insomnia symptoms and sleepiness in specific groups of participants. However, further research with objective measurements of sleep is crucial to assess the relationship between sleep and vitamin B12.
B12 deficiency can trigger specific food cravings, most notably for meat, fish, or eggs, as the body seeks animal-based sources to replenish the vitamin, especially in those on vegetarian/vegan diets or older adults. While cravings for sugary or salty foods can also signal general B-vitamin issues, the distinct urge for protein-rich animal products is a key indicator, but professional testing is crucial for confirmation.
Symptoms of vitamin B12 or folate deficiency
Typically, vitamin B12 injections provided by medical professionals range from approximately $20 to $80 per injection. We focus on providing transparent pricing and personalized care, ensuring you fully understand the cost and value of your treatments.
Cutaneous manifestations associated with vitamin B12 deficiency are skin hyperpigmentation, vitiligo, angular stomatitis, and hair changes. A diagnosis of vitamin B12 deficiency is often overlooked in its early stages because these signs are not specific to vitamin B12 deficiency alone.
The foods highest in Vitamin B12 are animal products, with clams and liver (beef, lamb) being exceptionally rich sources, often providing several hundred percent of the daily value in a single serving, alongside seafood like mussels, sardines, and salmon, dairy, eggs, and fortified cereals and nutritional yeast for vegans.
