Book a VITAMIN D BLOOD TEST WITHOUT THE WAIT
Testing first is the whole point, and it takes one appointment.
A vitamin D blood test tells you whether you are deficient, insufficient or fine, and the number decides what treatment you actually need. Symptoms alone do not tell you, because tiredness and aching have a long list of possible causes and vitamin D is only one of them.
If the result shows deficiency, you and the doctor decide between tablets and an injection based on how low it is, whether absorption is a problem, and whether you will realistically take something daily.
If the result is normal, you have saved yourself £95 and found out that something else is causing how you feel. That is a useful appointment, not a wasted one.
Why patients choose PRIVATE VITAMIN D SERVICE
• Tested, not guessed. Blood test available in the same clinic.
• £95 an injection, published, and only recommended where it is the right answer.
• 300,000 IU in a single dose, lasting three to six months.
• Given by a GMC registered doctor, who reviews your history and your result.
• A retest afterwards, so you know it worked and you are not over treated.
• We will tell you when tablets would do the same job, and they usually will.

VITAMIN D INJECTION OR TABLETS: which do you need?
For most people with vitamin D deficiency, tablets are the first answer, and they work.
Why tablets usually win. Oral vitamin D is well absorbed by most people, it corrects a deficiency reliably, and it costs a few pounds a month rather than £95 a dose. A page selling injections should say that, and most do not.
When an injection is genuinely the better choice:
• Absorption problems. Coeliac disease, Crohn’s disease, cystic fibrosis, or after bariatric or bowel surgery, where a tablet may not get in.
• You will not take a daily tablet. Not a character flaw, just a fact about how treatment actually goes. A single injection that lasts months beats a daily tablet that stops after two weeks.
• Severe deficiency, where a loading dose is needed and adherence matters.
• Difficulty swallowing tablets.
What the injection is. A single intramuscular dose of 300,000 IU of vitamin D3, typically lasting three to six months.
Either way, get retested. Vitamin D is stored in the body, so it is one of the vitamins you can have too much of. A repeat level after treatment tells you whether you needed the next dose or not, and that is the check that stops over treatment.

How often do you need a VITAMIN D INJECTION
Typically around three times a year, though this depends on your level, your absorption and the time of year.
The interval should be set by a blood test, not a diary. Vitamin D is fat soluble and is stored, so repeated high doses without checking the level can push it too high. Ask for a retest before your next injection rather than booking it automatically.
Winter matters more than summer. Between roughly October and March, UK sunlight is not strong enough for the skin to make vitamin D, which is why deficiency is seasonal and why many people need less, or nothing, over the summer.
If you are on tablets instead, a daily maintenance dose through the winter is what most people need, and that is cheaper and easier to adjust.
Before you pay: VITAMIN D TESTING AND TREATMENT ON THE NHS
- Your NHS practice can test and treat vitamin D deficiency, and where a test shows you need treatment, prescribed vitamin D is usually the route.
- People come to us because they want the test done this week rather than waiting, because they want the injection rather than tablets, because they are not registered locally, or because their practice has declined to test without a specific reason to.
- That last one is worth knowing. NHS practices do not test everyone, because the guidance is to test people with symptoms or risk factors rather than as a general screen. If you want to know your level and your practice will not test, that is a legitimate reason to pay for it privately.
- But if you already have a confirmed deficiency and your practice will prescribe, that is cheaper. We will say so.
VITAMIN D INJECTION FAQS
£95 for a single 300,000 IU dose, given by a doctor.
Not for most people. Tablets work, and they cost a few pounds a month. An injection is better where absorption is a problem, where a daily tablet is not realistic, or where deficiency is severe.
Typically around three times a year, but the interval should be set by a blood test rather than a calendar.
Yes, where there is a reason to test. Practices do not test everyone, which is why some people pay to find out their level.
Into a muscle, usually the upper arm or thigh. A couple of minutes.
Anyone with a high blood calcium level, some kidney conditions, or sarcoidosis. Tell us your history at booking.
Yes, and it is the point. Your level decides whether you need treatment at all, and whether tablets or an injection is the right answer.
Three to six months, depending on your starting level.
Yes. It is stored in the body, and a high level raises blood calcium. That is why retesting matters and why repeat doses should not be automatic.
Only if vitamin D deficiency is the cause. A test is what tells you.
Usually nothing beyond a sore arm. The one to be aware of is too much vitamin D over time, which is avoided by testing.
Often less, or not at all. UK sunlight between April and September is usually enough for most people to make their own.

£95 for the injection if you need one, and a blood test before it so you know whether you do. Same day appointments, no referral. If tablets would do the same job for a few pounds a month, we will tell you that instead.
