Vitamin injections are one of the few things on my price list where the answer to “how much?” is boring, and I think boring is the point. Vitamin B12 is £35. Biotin is £35. Vitamin C is £35. Fifteen minutes each, and the booking button takes you to the injection itself rather than to a consultation about it.
I am Natasha. I run House of Glam HQ on Auckland Road East in Southsea and I give every injection in this clinic myself. What follows is what the three cost, what the £35 actually covers, and the part that usually gets left out, which is what a vitamin injection will not do for you.
What a vitamin injection costs in Portsmouth
Here is the whole list. There is no fourth option behind a form and no package price to work out.
| Injection | What it is | Price |
|---|---|---|
| Vitamin B12 | Intramuscular injection into the upper arm, about 15 minutes | £35 |
| Biotin | Vitamin B7, same injection, same 15 minutes | £35 |
| Vitamin C | Ascorbic acid, same injection, same 15 minutes | £35 |
Every price is published, where most Portsmouth clinics quote only after a consultation. On a £35 treatment that matters more than it sounds, because a consultation fee attached to a £35 injection changes what you are really paying by half again.

Why all three are the same price
People ask this, usually expecting Vitamin C to be the cheap one or biotin to be the expensive one. They are the same price because they are the same appointment. One vitamin, one measured dose, one single-use needle, into the muscle of your upper arm, about fifteen minutes from hello to done. The thing in the syringe changes. Nothing else does.
I could price them differently and dress it up. I would rather have a list you can read in ten seconds.
What the £35 actually covers
The injection, the needle, the few minutes of questions I ask before I give it, and me doing it rather than handing you to somebody else. There is nobody else here. I do every treatment in this clinic, including this one.
What it does not include is a separate consultation fee, because there is no separate consultation to book. I go through your health, your medicines and anything you are already taking at the start of your appointment, at no extra cost, and if the answers point the wrong way then I say so and you do not pay for an injection you should not have.
What it comes to if you keep booking
Most people who come back book again somewhere between every four and every eight weeks. Plenty book once out of curiosity and leave it there. Nobody here is put on a schedule. But if you are the sort of person who wants to know what a habit costs before you start one, the arithmetic is straightforward.
| How often you book | Injections in a year | What that comes to |
|---|---|---|
| Once, to try it | 1 | £35 |
| Every eight weeks | 7 | £245 |
| Every six weeks | 9 | £315 |
| Every four weeks | 13 | £455 |
I show you that because £35 reads as nothing and four hundred and fifty five pounds reads as something, and they are the same decision twelve months apart. Worth knowing before you start rather than after.
Are B12 injections worth the money?
It depends entirely on why you are asking, and there is one answer here that I will give you before I take your booking.
If a doctor has diagnosed you with a B12 deficiency, that is a medical matter and it belongs with your GP, who will treat it and monitor it. That is not what this appointment is. A clinic injection does not replace their advice, their blood tests or their prescribing, and I am not going to take £35 off you to stand in for it.
If you have been taking B12 in tablet form for a while and you want to try it as an injection instead, that is the reason I hear most often and it is a fair one. An injection goes into the muscle rather than through the gut, so how it gets in does not depend on how well your digestion takes things up. That is a difference in how it is given. It is not a reason to stop anything your GP has you on.
What I will not do is tell you how you will feel afterwards. What one person notices, the next does not, and there is no honest way to promise you a feeling from a vitamin.
Do biotin injections actually work?
Biotin is vitamin B7, and the body uses it in normal keratin production, which is the reason it turns up in every hair and nail supplement on the shelf. That is what the vitamin does in the body. It is not a promise about what an injection will do to your hair.
I cannot tell you that a biotin injection will thicken your hair or stop your nails splitting, and I am not going to, because I do not know that and neither does anybody selling it to you. Most people who book biotin here have already been taking it as a tablet and want to try it this way. That is the honest version of the reason, and it is the one I hear.
If you are losing hair and you do not know why, that is worth a conversation with your GP before it is worth £35 with me.
How long does a biotin injection last?
The appointment lasts about fifteen minutes. As for the dose, biotin is water-soluble, so the body does not store it the way it stores fat-soluble vitamins, and what it does not use it passes. That is why people book them repeatedly rather than once.
I am not going to give you a number of weeks, because I would be making it up. What I can tell you is what people actually do, which is somewhere between every four and every eight weeks, and that plenty do it once and never come back and are perfectly happy.
What should you not mix with biotin?
The one genuinely useful thing to know here has nothing to do with other supplements. Biotin at high doses is known to interfere with some laboratory blood tests, because a lot of common tests use biotin in the chemistry that makes them work. It can push results high or low, and the lab cannot tell that it has happened.
So if you have had a biotin injection, or you are taking a high-dose biotin supplement, tell whoever is taking your blood, and tell your GP. Let them decide whether to wait. It is a two-second sentence that saves a confusing result, and almost nobody selling biotin mentions it.
Beyond that, tell me what you are already taking when you sit down, and tell me about any medication you are on. That is what those few minutes at the start of the appointment are for.
Is a vitamin injection a “metabolic booster shot”?
No, and I want to be blunt about this one because the phrase gets searched a lot around Portsmouth.
What I sell is one vitamin, given as one intramuscular injection, for £35. It is not a weight-loss treatment. It will not speed up your metabolism. I do not offer weight-loss medication of any kind, and if that is what you came looking for, this is not it and I would rather say so on this page than after you have paid.
“Booster shot” is a marketing name. The thing underneath it is a vitamin.
Vitamin C, and why it gets booked in winter
Vitamin C is ascorbic acid, given the same way, in the same fifteen minutes, for the same £35. It contributes to normal collagen formation and to normal immune function, which is what the nutrient does in the body and is why it gets booked far more between October and February than at any other point in the year.
Same caveat as the other two. I can tell you what is in it and how it is given. I cannot tell you how it will make you feel, and I would not trust anyone who says they can.
What a vitamin injection will not do
This is the section I would want to read if I were you.
It will not tell you whether you are deficient in anything. Only a blood test does that, and your GP orders it. It will not treat a diagnosed deficiency, which is medical care and belongs with your doctor. It will not make you lose weight. It will not fix hair loss with a cause nobody has looked for yet. And it will not come with a promise about how you will feel next Tuesday, because I do not make those.
What it is: a measured dose of one vitamin, into the muscle, by a named person, for a published price, in a quarter of an hour. That is the whole of it, and for a lot of people that is exactly what they wanted.
What happens in the fifteen minutes
You book the injection on Fresha. There is nothing to sit through first. When you arrive I ask about your health, your medicines, what you are already taking and whether you have had an injection like this before. That takes a couple of minutes and costs nothing extra.
Then the injection itself. Skin cleaned, single-use needle, intramuscular into the upper arm. Most people describe it as a brief sharp scratch and it is over in seconds. Afterwards you go straight back to your day. Some people get a little redness or soreness at the site for a few hours, and most get nothing at all.
Because it only takes fifteen minutes, it sits neatly at the end of another appointment. If you are already booked in for filler, anti-wrinkle injections or something on the skin side, book the two together on Fresha and they happen in the same visit.
Who should not book one
Message me before you book if you are pregnant, breastfeeding, taking regular medication or being treated for anything. Some conditions and some medicines make this unsuitable, and I would rather tell you on WhatsApp than at the door. Vitamin injections here are for adults only.
And if you have been told you are deficient, start with your GP. I will say that to your face in the clinic, so I may as well say it here and save you the trip.
How to book, and the prices one more time
All three injections are £35, all three take about fifteen minutes, and each one has its own booking so you pick the one you want rather than a menu. Everything about the treatment, including the full list, sits on the vitamin injections in Portsmouth page.
If you would rather ask me something before you spend £35, message me on WhatsApp or call 07831 846273 and I will answer straight, including if the answer is your GP rather than me. Klarna spreads bigger treatments over three monthly payments, but at £35 a vitamin injection is not one of them.
