Vitamin B12 

How Do Vitamin B12 Injections Work?

Vitamin B12 is a vital component in ensuring we function properly in our day to day lives. It helps us stay energetic, protects us against a number of health issues.Studies have even suggested that it can improve your memory and overall brain function as well as;​

  • Improves Energy

  • Combats Fatigue

  • Essential for Healthy Hair, Nail & Skin

Why is an injection effective?

An injection is one of the most effective ways to get B12 and is typically used for those who might not benefit from tablets, liquids or capsule supplements for any reason. They are typically injected into a muscle. They can be administered whether you are pregnant or breastfeeding, your diet and if you have any existing medical conditions. As Vitamin B12 is also water-soluble, any excess of the vitamin that your body doesn’t need or have the capacity for will pass through and remove any risk of overdose.

B12 can provide a number of benefits, from reducing the risk of deficiency-related conditions to improving brain function, bone health and giving you an overall energy boost. 

Reduced risk of associated complications

Even if you aren’t showing pressing signs of a B12 deficiency, many of us still aren’t getting the right volume every day, particularly if we’re sick, pregnant or breastfeeding. Vitamin B12 shots can help to prevent the associated complications of deficiency, including heart disease, coordination problems, vision loss, infertility, neurocognitive disorders and peripheral neuropathy. Some of these conditions can be solved with an injection, but we can discuss this with you on a case-by-case basis.

Higher Level Of Absorption

When injected into the body, Vitamin B12 can bypass the gastrointestinal tract and go directly where it’s needed – for this reason, a shot can be a better choice than oral supplements for a higher level of assimilation. This is particularly beneficial for adults over 65 and those with problems or previous surgery in the digestive tract.

May Help Brain Function

While B12 can’t necessarily improve your brain function on its own, it can help to prevent the loss of neurons associated with memory reduction. Some studies suggest that it can even slow down the development of dementia and Alzheimer’s Disease.

It has also been suggested that B12 deficiency could be a cause of poor memory on a shorter-term basis, which may be helped by a B12 injection or supplement.

Vitamin B12 prevents the loss of neurons in the brain, helping to improve brain function and prevent memory reduction.

May Reduce Depression Risk

Studies into depression have suggested that low B12 can be a  cause of a depressed mood. B12 is a key player in the production of the mood-regulating chemical serotonin and when your body is lacking the vitamin, production can decrease. While B12 injections can’t cure depression on their own, they have been known to relieve or reduce some of the symptoms and can also be used to reduce the risk of severe cases of depression.

May Promote Bone Health

While a B12 shot won’t immediately solve any bone-related issues you may have, the ongoing maintenance of a healthy level may help to promote your bone health. Those suffering from B12 deficiency have been known to have lower than normal bone mineral density, which can lead to osteoporosis over time

May Give An Energy Boost

All B vitamins, not just B12, play an important part in how your body produces energy. A lack of B12 in the body can lead to fatigue and tiredness and for this reason, those of us with a deficiency could see an energy boost after a Vitamin B12 injection

Before attending your appointment, it is preferred (but not required) that you have a recent blood test to check your B12 level.

If you cannot access a blood test through your GP, you can purchase self tests and have them delivered to your home from one of the companies below.



The recommended dosage of vitamin B12 injections for B12 deficiency is 1000 mcg (1 injection) every 2-3 months. If you require B12 for a deficiency you will need a blood test prior to attending the clinic or have your recent blood test results. If you simply wish to have B12 injections for wellbeing or dietary purposes we are able to administer these every 6 months.

A small IV butterfly needle will be gently inserted to gain access if an infusion is to be administered, or the injection is prepared is an intramuscular route is to be used.
