There is no evidence that jabs can help those who are not deficient in B12. The doses involved are usually many times the levels the body can absorb, so most of the B12 is rapidly excreted in urine. It could be that apparently healthy people who report benefits may have undiagnosed B12 deficiency.

Geeta Sidhu-Robb, founder of Nosh Detox, which sells B12 injections and infusions at Harvey Nichols in Knightsbridge, London, believes her customers do benefit. To feel OK and to feel great are two different states, she says. If you look at somebody and think will they get an awful lot more energy, yes, I do think that it does make a big difference.

Collins believes any perceived benefits in healthy people are down to a placebo effect. B12 injections and infusions for healthy people create an aura of fabricated need. Its like having a plaster put on your knee and getting a cuddle when you fall over.

Vitamin B12 Deficiency Symptoms

Insane Benefits of Vitamin D3, C,B12 Booster Shot ...

Vitamin B12 deficiency can be slow to develop, causing symptoms to appear gradually and intensify over time. It can also come on relatively quickly. Given the array of symptoms a vitamin B12 deficiency can cause, the condition can be overlooked or confused with something else. Vitamin B12deficiency symptoms may include:

  • strange sensations, numbness, or tingling in the hands, legs, or feet
  • difficulty walking
  • difficulty thinking and reasoning , or memory loss
  • weakness
  • fatigue

While an experienced physician may notice the symptoms and be able to detect a vitamin B12 deficiency with a good interview and physical exam, a blood test is needed to confirm the condition.

Its a good idea to ask your doctor about having your B12 level checked if you are a strict vegetarian or have had weight-loss surgery or have a condition that interferes with the absorption of food.

Early detection and treatment is important. If left untreated, the deficiency can cause severe neurologic problems and blood diseases.

Vitamin B12 Deficiency Recovery

Treatment for vitamin B12 deficiency usually consists of supplementation, but the type of supplement you need depends on the severity of your deficiency and what the underlying cause is. According toHarvard Health, a severe vitamin B12 deficiency can usually be corrected with either regular vitamin B12 shots or high-dose B12 pills or capsules. If your deficiency is on the milder side, an over-the-counter multivitamin or B complex supplement is usually enough to do the trick.

If you’re getting B12 injections, they’re usually administered by a health care professional every other day for two weeks and then monthly for three months. However, if your deficiency is so severe that you’ve developed neurological symptoms, like numbness and tingling in the hands and feet or difficulty balancing, then you’ll be given an injection every other day until those symptoms resolve, and then once a month for two months.

Most standard B12 injections contain 1 milligram of vitamin B12, but you absorb only about 10 percent, or about 100 micrograms, of the vitamin. However, even though you absorb such a small amount, that’s still almost 40 times more than the amount that you need for the entire day .

You Can Manage Any Pain From The Shots

Every person has a different pain tolerance. We understand that. There are, however, factors that can increase or decrease how you experience pain from a shot.

Pain is more common if youre tense, dehydrated, or youve just worked out the muscle into which the shot is being injected.

If youre relaxed in both mind and body, well-nourished and hydrated, and havent been working out that muscle, youre likely to experience less pain. Keeping hydrated also decreases the risk of bruising from an injection.

Our goal is to administer shots so that they cause little to no pain. We will instruct you on how to stand and breathe for the most comfortable experience.

Keep in mind if youre someone who wears heel, this tenses up your glutes, so you may want to remove your shoes during the injection or not wear them at all that day!

Vitamin B12 Shots Are Sterile

If you go to a trusted source like your doctor or nurse practitioner, you shouldnt have to worry about whether or not the injections are sterile. Healthcare providers purchase injectable solutions from certified compounding pharmacies.

Further detail about this, if you like that sort of thing:

These pharmacies are generally certified through the Pharmacy Compounding Accreditation Board . Eight of the nations leading pharmacy organizations formed this nonprofit organization.

Not only does PCAB provide a voluntary accreditation program for compounding pharmacies across the country, they promote, develop, and maintain principles, policies, and standards for improving the quality of pharmacy compounding nationwide.

Laboratories and manufacturing facilities that make the injections are certified by globally recognized institutions such as the US Food and Drug Administration . They also meet validated manufacturing standards such as Good Manufacturing Practice .

The usual frequency for intramuscular doses of B12 shots is every 10 days, followed by maintenance doses at varying intervals. After this period, you may be able to administer the injection once per month. This frequency is enough to reverse the signs of vitamin B12 deficiency. While taking the vitamin, it is also important to keep up with a proper diet to meet your bodys nutritional needs.

Vitamin B12 can be found in the form of cyanocobalamin, hydroxocobalamin, and methylcobalamin. Each of these forms may have different indications and uses. Consult your doctor on the most appropriate formulation for your condition.

How To Treat A Vitamin B12 Deficiency

Treatment for vitamin B12 deficiency depends on what is causing the condition. Most conditions are treated with injections, diet, intravenous vitamin drips, or supplements to increase the lacking vitamin.

Injections for vitamin B12 are available in several forms. The most commonly used forms for deficiency treatment include hydroxocobalamin and cyanocobalamin. Health care professionals typically favor hydroxocobalamin as it remains in the body for a longer period of time. Initial treatment requires injections to be administered more frequently. As levels return to a normal range, the number of injections decreases and attention is paid to obtaining B12 from dietary sources.

For B12 deficiencies caused by diet-related conditions, patients may be prescribed a B12 supplement to take between meals. Those who have difficulty getting enough B12 in their diet may be required to take supplements for life to ensure that deficiency and symptoms are eliminated. Good sources of vitamin B12 include meat, fish, milk, dairy products, and eggs. Also, B12 shots benefit those who need immediate treatment in addition to long term management.

What Factors Lead To B12 Deficiency


Any illness or condition that affects the digestive system can result in a B12 deficiency because the vitamin is bound to the protein molecules in your food and is released and absorbed by the body during digestion. Such conditions include autoimmune conditions such as Crohns disease, celiac disease and ulcerative colitis, which all prevent the body from adequately absorbing nutrients from the intestines.

Additionally, other factors such as having had gastric bypass surgery or taking antacids long-term can lead to deficiency. This is because adequate exposure to stomach acid is needed to help the body absorb B12.

Lifestyle Choices

You are also significantly more likely to suffer from B12 deficiency if you practice a vegan diet and lifestyle. This is because there are few vegan foods that contain B12 and also because the body finds it significantly more difficult to absorb B12 from the few vegan sources that have it. Many foods are fortified with artificial vitamin B12, such as non-dairy milks and cereals, but these are not always optimally absorbed, so vegans must still be proactive about making sure they are not becoming deficient.


You are more likely to be B12 deficient if you are over the age of 65, as the body becomes less efficient at absorbing nutrients as you go on in life.

Who Needs B12 Injections

How long do Botox Injections last? – Dr. Ashok B C

Dietary deficiency can be treated with tablets. Those with problems absorbing B12 from the stomach are often given hydroxocobalamin, an injectable form of B12. This is given six times over two weeks, followed by once every three months. NHS guidelines say those with neurological symptoms should receive more frequent treatment, but some patients complain this is often ignored.

Campaigners are calling for more frequent testing and treatment. Dogs diagnosed can have B12 injections weekly, so why cant humans? asks Tracey Witty, who launched a petition for injectable B12 to be made available over the counter, as it is in France and Germany. Most of the dose is excreted within 24 hours, so many patients are on their knees for probably 10 of the 12 weeks between injections, or they feel forced to buy B12 online from abroad, she says.

Where Can I Get An Injection

In the U.S., your primary care doctor can test your levels and administer them in the office. Some local pharmacies also offer them.

In the U.K., you can only get B12 injections for medical purposes with a prescription. However, a number of clinics are able to offer the shot as nutritional therapy. Take the Harpal Clinic, for exampleprices start at £35 for one session carried out by an IV physiologist, with a course of six injections available for £189.

As far as how often you get them, it depends on your specific needs. “The schedule of administration is something that will depend on your medical situation and how deficient you are, so you should talk about it with your doctor,” says Avena. “Some regimens call for daily shots for about a week, and then monthly after that, while others find a shot every few months works for them.”

    Do Vitamin B12 Shots Work?

    If you have a major deficiency, you may feel nothing after your first visit. You will need to visit us more frequently to get your B12 back up to healthy levels. With low B12 levels, you may notice the benefits for a shorter period. Often, patients with low B12 have hours to days of symptom relief.

    If you have moderately sufficient B12 levels, the beneficial effects often last longer. The more B12 you have in your system, the longer you can likely go between injections.

    What Are The Symptoms Of Vitamin B12 Deficiency

    You may not experience any symptoms of a B12 deficiency. Some patients, especially those with a mild deficiency, remain asymptomatic unless the deficiency turns into anemia. Busy lifestyles can sometimes mask the symptoms of not having enough B12. If you often feel sleepy, its better to investigate vitamin B12 levels in the body instead of explaining it away.

    You may notice any one or more of the following from a B12 deficiency:

    • Tiredness
    • Numbness or tingling
    • Vision changes

    If you experience any of the signs above, a vitamin B12 injection could put you back on your wellness path.

    Helps Stop Certain Types Of Hair Loss

    Hair loss is so common in men, that a B12 deficiency as the cause of it is often missed. Because cells are not being metabolized efficiently, it is difficult for hair growth to occur normally. Regular B12 shots restore your bodys ability to metabolize, and cause your hair to begin growing as usual.

    B12 injections are highly recommended for those who have a deficiency. The synthetic chemical, cyanocobalamin, is not easily absorbed by your body, but methylcobalamin is. Depending on your condition, you may need to get a B12 injection every few weeks until your deficiency is gone. If you have a medical condition where you are unable to absorb sufficient B12 from your diet, you will need to get a shot every month to stay healthy.
