Nutritional deficiencies cause many health issues. The traditional route to treating nutritional deficiencies is diet modification and oral supplements, but health professionals increasingly prescribe vitamin injections to patients.
This article focuses on vitamin B12 injections, explaining why they are popular and what benefits to expect from the therapy.
B12 injections prevent and treat low levels of vitamin B12. Doctors often prescribe them to patients suffering from B12 deficiency or pernicious anemia (a condition caused by B12 deficiency). The injections deliver high doses of B12 directly into the bloodstream for quick vitamin absorption.
B12 is an essential vitamin that regulates the production of red blood cells and DNA, brain function, nervous system health, and conversion of food into sugar. Chronically low B12 levels can lead to various medical conditions, including neurological and heart problems.
Recently, B12 injections have gained popularity as a wellness treatment to improve mood, increase energy, and help with weight loss.*
There are three types of B12 injections:
Patients with low levels of vitamin B12 benefit the most from B12 shots. The following categories of people are the most susceptible to B12 deficiency:
The main advantage of B12 shots over oral vitamin B12 supplements is efficient absorption. Because the injection bypasses the digestive tract, as much as 80-90% of the vitamin is absorbed.
Regular use of vitamin B12 injections helps increase B12 levels and may provide the following health benefits.
Vitamin B12 has an important role in brain function, enhancing neuron production and repair. Studies suggest that depleted levels of B12 lead to memory loss and cognitive decline. The injections may help reverse the effects of brain degeneration, restoring memory, concentration, and cognitive function in people with B12 deficiency.*
Vitamin B12 helps transform food into glucose, which blood cells use to make energy for essential bodily functions. Low B12 levels slow down these metabolic processes, leading to exhaustion and fatigue. The injections help improve metabolism*, with patients reporting they feel more energetic and less tired.

Studies show vitamin B12 deficiency is linked to lower bone density, suggesting that optimal B12 levels may contribute to stronger bones and reduce the risk of osteoporosis, especially in older women.
Vitamin B12 plays an essential role in red blood cell formation and homocysteine regulation. Low B12 levels may cause a type of anemia that is a risk factor for cardiovascular diseases. Increased homocysteine levels due to B12 deficiency leads to blood vessel damage and heart disease.
Restoring optimal B12 levels with supplements or injections may protect the heart and reduce the risk of heart disease.*
Vitamin B12 is essential for dopamine and serotonin synthesis. These two neurotransmitters regulate many bodily functions, including the sleep cycle and mood. They are known as the “feel good” hormones, elevating feelings of satisfaction, pleasure, and achievement. They also play a role in sleep quality and duration, assisting in the production of melatonin which regulates the sleep-wake cycle.
Patient experience shows vitamin B12 injections help improve mood, reduce anxiety and depression, and relieve insomnia.*

Vitamin B12 injections have gained popularity as an effective tool in weight management and can be found in popular medical weight loss programs.* They may reduce various symptoms that cause weight gain, including stress and poor sleep.* The positive effect of using vitamin B12 for weight loss can be seen in the way it helps break down food and transforms it into energy. As a result, the patient is provided with the strength and stamina needed for regular exercise.

Getting a vitamin B12 injection doesn’t require any special preparation. However, talk to your medical provider about the medications, supplements, and other substances you use to ensure they don’t interact with the therapy.
Your provider may recommend discontinuing the use of the following medications and supplements for three days to avoid bruising:
Doctors also recommend avoiding alcohol and eating a light meal before the treatment.
The provider first cleans the injection site with alcohol and injects the vitamin B12 solution. They can administer the shot into a muscle (intramuscularly) or deep under the skin (subcutaneously). The arm, thighs, and buttocks are the usual sites for intramuscular injection, while subcutaneous shots are usually given in the upper arm, lower abdomen, or thigh.

Medical providers administer vitamin B12 injections in clinics, med spas, and other medical settings. Patients can also self-administer the shots following their doctor’s instructions.
The injection dose differs for every patient depending on their age, sex, physique, health goals, and other factors. The typical dosage for adults is 30-1000 micrograms administered daily, on alternate days, weekly, monthly, or as the physician recommends.
The dose changes with time depending on the patient’s response to the treatment and B12 levels in the blood.
Patients with a deficiency may need a higher dose and daily treatment, while patients who want to improve their overall health may come in for the therapy once in two or three months.
Vitamin B12 injections are safe and usually cause mild or no side effects. More common symptoms include:
