Intramuscular Boosters
An intramuscular booster is an injection designed to deliver vitamins and nutrients directly into the muscle, allowing the formula to be absorbed into the muscles and bloodstream quickly and efficiently. Quicker than an IV drip but less comfortable and with a lower level of bioavailability than an IV, they are perfect for those in a hurry.

Reviews
Recently had my fourth IV drip with Effect Doctors. Each time has been incredibly helpful and if I could, I would simply do these all the time. The drips are absolutely wonderful, and have taken me from feeling exhausted and depleted, to rejuvenated, energised and raring to go. On this occasion we had an out of clinic experience where the doctors came to our apartment. It was a super professional set-up, and our group were well looked after by experienced nurses and doctors who made the whole experience relaxing, safe and enjoyable. Dr Will Buxton couldn’t have been more helpful in coordinating everything, and I’m already looking forward to my next treatment with Effect Doctors!
Super lovely staff, and thank goodness the crew booked these for my hen party For the morning after, otherwise I'm not sure how we would have continued into the next morning !! Really sorted us all out. Felt rejuvenated over the day, and energy was intact !! Would 333% recommend the IVs and this team. 🙏🏻✨⚡⚕️🔮🪄✨
Big thank you to both Allie and Dr Klapan!
I called this Tuesday, after the Bank Holiday, full of questions on how to navigate the process and get some iron for a severe deficiency. They were excellent.
Allie patiently explained the process and managed to fit me in just a few hours later.
Dr Klapan was welcoming, thorough in her health checks, and reassuring. It was a very calming space for an infusion, and I felt very comfortable there. Dr Klapan administered the infusion and was sure to check on patients regularly throughout. She created a very calming environment.
The clinic itself is also very comfortable. I'd recommend, whilst we all try to avoid going to clinics... I'll definitely be returning!
Thanks again.

I had my treatment at the Westfield Clinic and was treated by Dr. Nathan. It was a wonderful experience, and I’m looking forward to future treatments with the clinic.
I had an injection at the clinic. It was so easy to book, the website is very easy to navigate and prices are really good, Better than other clinics. The health questionnaire was very quick. The staff are lovely and very friendly, the clinic is a nice place to relax whilst getting your treatment. The whole process from start to finish was really easy and stress free, very impressed. Will definitely be back.
I probably have been struggling with my iron deficiency for few years, and it only became a big issue in the last 6 months. I went through very distressing hair loss, when in a short space of time I've lost about 50% volume of my hair. I tried to get some help from GP and in the last 10 weeks of their care my levels have gone so low that I wasn't able to function properly. All I heard was I couldn't feel the way I felt only from low iron, it was suggested maybe I was stressed, or my life style was making me so fatigued, my heamoglobin was still holding therefore I was fine... When I contacted effect doctors the response was almost immediate along with forms and lots of information. When I came for my consultation I felt someone acknowledged me for the first time. I was very excited for what was to come, the process was smooth, all the information and very good letter for my GP - hopefully it will push them to actually help me to find out the reason behind my low ferritin. I had few side effects, but I was informed about the possibility and I knew what to expect. The only thing I regret is waiting for my GP to do more for me and not getting the iron infusion sooner. Thank you for giving me my light back.
Having Effect Doctors at Glampville has been a fantastic addition for our Glastonbury guests. Their clinical-grade IV drips provide highly effective, rapid recovery from long days in the fields. Beyond the treatments themselves, their team is incredibly professional and brings great energy to the campsite every morning. They provide an impeccable service, and we are very proud to partner with them.
I had a really positive experience with Effect doctors for an Iron infusion. The doctor was incredibly nice and reassuring and was totally open to answering all my questions. I would recommend and would return without hesitation.
I have been having IV with excellent results. A wonderful nurse called Shereen has been administering it and she has made my entire experience comfortable and even enjoyable. Her caring, knowledgeable and professional approach prepared me well. She is willing to adjust the IV throughout the process for my comfort. I feel blessed to have her taking care of me and Effect Doctors are most fortunate to have her in their employment.
FAQs
What is the difference between an intramuscular injection and an IV drip?
An intramuscular (IM) injection delivers a single nutrient, such as B12 or Vitamin D, directly into the muscle, where it’s gradually absorbed into the bloodstream. An IV drip delivers a blend of vitamins, minerals and fluids straight into a vein, bypassing digestion entirely for faster, more complete absorption. IM boosters are quicker to administer and ideal for a single top-up, while IV drips suit those wanting hydration alongside a broader, tailored nutrient blend.
How long does a vitamin injection appointment take?
The full process, from a brief check-in to the injection itself, usually takes less than 20 minutes. No downtime is needed afterwards, so you can head straight back to your day.
Can I get a same-day or walk-in vitamin injection in London?
Yes, pre-booking isn’t always necessary and we welcome walk-ins at our Westfield clinic, with same-day appointments often available at both our Soho and Westfield locations. If you’d like to guarantee a specific time, we’d recommend booking online or calling ahead.
How long do the effects of each injection last?
This depends on the booster. B12 effects typically last 2-6 weeks depending on your baseline levels, while a Vitamin D injection can support healthy levels for up to 3 months. We can advise on the right frequency for you based on your symptoms and any blood results.
How quickly will I feel the effects of each injection?
This varies by booster; most people notice more energy from a B12 injection within 24-72 hours, for example. Our team can talk you through what to expect for your chosen booster during your appointment.
Which vitamin injection is best for tiredness and low energy?
Our B12 Booster is the most popular choice for tiredness and low energy, as B12 plays a key role in energy production and red blood cell formation. If fatigue persists, we’d recommend a blood test such as our Tired All the Time panel first, to check for underlying causes like iron deficiency or thyroid issues before choosing the right injection.
Which vitamin injection is best for hair loss and nails?
Our Biotin Booster is formulated to help strengthen brittle nails and support hair health, alongside good general nutrition. Since hair loss can also be linked to iron or thyroid issues, we’d suggest a blood test such as our Iron and Micronutrient Panel if hair thinning is a persistent concern.
Which vitamin injection is best for skin and antioxidant support?
Our Glutathione Antioxidant Booster is designed to support skin appearance, energy and overall antioxidant defence by helping the body clear free radicals and toxins. It’s a popular choice for those looking to support skin health from within.
