Give yourself an energy boost and improve your weight loss efforts at our Cardiff clinic

Are you feeling tired, sluggish, and lacking in energy? Do you struggle to concentrate, or find yourself forgetting things? If so, you may be deficient in vitamin B12. B12 is responsible for a wide range of bodily functions, from the production of red blood cells to the maintenance of a healthy nervous system. However, many people don’t get enough B12 from their diet alone. Injections of vitamin B12 are a simple and effective way to boost your levels and enjoy a range of health benefits. They can also be used to support weight loss.

“Excellent service so pleased with the natural look I’m being given and it’s making me feel far more confident. Dr Kathryn is simply the best!”


All things skin

Expert advice on achieving your B12 goals and maintaining them.

If you suspect you’re suffering from a lack of vitamin B12, and you’d like the health and energy boost or weight loss effects, this treatment can provide, why not book a consultation with Dr Kathryn? She will test you for a B12 deficiency, and give you expert medical advice on the dosage you’ll need, before drawing up a treatment plan. Dr Kathryn will worry about your maintenance of the perfect vitamin balance for maximum health benefits, so you don’t have to.

Treatment journey

Your treatment journey



During the consultation, Dr Kathryn will evaluate your medical history, current medications, and symptoms to determine if B12 injections are necessary. You’ll have a discussion about the dosage and frequency of injections, as well as any potential side effects or risks associated with them. Some dietary changes, or other supplements, may be suggested to support the effectiveness of the B12 injections.



Dr Kathryn will clean the injection site, and then administer the injection directly into the muscle tissue. The injection site is usually the upper arm or thigh. Once the injection has been administered, pressure will be applied to the area. You will be given a reminder of when your next injection will be due.


Skin care

The injection site should be kept clean and dry afterwards to prevent infection. You may experience soreness here for a short period afterwards. We’ll recommend you avoid any strenuous activity or exercise for at least 24 hours after the injection to allow the body to fully absorb the vitamin. Regular follow-up appointments with us will help you monitor B12 levels.


Questions about your treatment

  • A deficiency in vitamin B12 can lead to fatigue, weakness, and even permanent nerve damage. It can also cause brain fog, mood swings, headaches, and memory issues. Having B12 injections should reduce these symptoms, boost your energy levels, and improve your overall health. B12 injections are also, in some cases, used for weight loss.

  • The length of the results depends on the amount of B12 you have in your diet, but we also take into account any factors that stop your body from efficiently absorbing B12. We’ll be able to give you an idea of how long the effects will last when you visit us for a consultation.

  • During your consultation for B12 injections you’ll have a discussion with Dr Kathryn about whether the injections are appropriate for you. Vitamin B12 injections are typically prescribed to individuals who have a deficiency in this essential nutrient and this treatment is deemed necessary to improve your overall health. They are also used in some circumstances for weight loss. Deficiency is more common in men and women who are 50+, as well as vegans who are struggling to get enough of the vitamin through their diet.

  • We would expect you to experience the initial health benefits of vitamin B12 injections 24-72 hours after receiving them.

  • The injections themselves feel like having any other injection. Your discomfort can be minimised with a topical numbing cream applied beforehand. Some patients may experience mild side effects afterwards such as nausea, headache, or dizziness, but these should soon subside.

“Kathryn is so professional and I feel completely confident in her hands. Highly recommended!”
