Benefits
An essential role
Vitamin D plays a role in bone health, muscle function and the immune system.
Faster correction
An injectable dose can correct a deficiency faster than a daily oral intake.
Easy to stick to
One administration at the clinic, instead of a daily oral schedule that is hard to keep to.
Useful when a deficiency is confirmed
Indicated mainly when blood tests show a low vitamin D level.
Quick administration
The intramuscular injection takes a few minutes.
Two doses available
100,000 IU or 300,000 IU, chosen according to your level and the medical recommendation.
IV drip or oral supplements — when each one fits
It is not “better or worse” — they have different roles. Here is the difference, stated fairly.
| IV drip | Oral supplements | |
|---|---|---|
| Absorption | Directly into the bloodstream | Variable, through digestion |
| When it fits | A one-off session, with a medical assessment | Daily intake, over the long term |
| Role | A medical procedure, personalised protocol | General support |
An IV drip does not replace a balanced lifestyle or the treatment recommended by your doctor.

Injectable vitamin D3 from the pharmacy — which forms exist
The active substance is cholecalciferol. Injectable forms are dispensed by pharmacies under several brand names — among them Dibase, at a concentration of 100,000 IU per millilitre. The doses commonly used in practice are 100,000 and 300,000 IU, given intramuscularly.
The difference between the two doses is not "stronger" versus "weaker", but the size of the reserve created and the interval until the next administration. Vitamin D is stored in fatty tissue and released gradually, so a higher dose covers a longer period — but it also carries a higher risk of over-correction if it was not needed.
The step before any administration is a 25-OH vitamin D blood test. Unlike water-soluble vitamins, where any excess is eliminated, vitamin D accumulates. The details: injectable vitamin D3 — where to find it.
When an injectable vitamin D makes sense
Vitamin D is involved in bone health, muscle function and the immune system. Deficiency is common, especially in the cold season. When the level is low and oral intake is not enough or cannot be kept up, an injectable (intramuscular) dose is an option for faster correction.
At Synerva, in Bucharest, we give injectable vitamin D after an assessment. Honestly: if your level is normal, a high dose brings no additional benefit — which is why the recommendation ideally starts from a test of your vitamin D level.
How it works
1. The assessment
A doctor discusses your level (from blood tests, if you have them), your medical history and your goal. The assessment is included.
2. The administration
The intramuscular injection takes a few minutes, at the clinic or at home.
3. After the administration
The dose and how often it is repeated are set individually, according to your level and the medical recommendation.
Who it is suitable for
The injectable route is chosen mainly by people with a confirmed vitamin D deficiency or who cannot keep to a daily oral schedule. The high dose requires a prior assessment — too much of a supplement is not risk-free.
We tell you honestly when an injectable dose makes sense and when oral intake is enough. We do not give high doses without a clear reason.
"Vitamin D injection" or "vitamin D3 injections" — what it means
They are the same thing, worded differently. The form given is cholecalciferol, that is, vitamin D3 — the form the body also produces in the skin when exposed to the sun. It is given intramuscularly, as a single injection that takes a few minutes, not as a drip.
At Synerva, in Bucharest, the vitamin D3 injection is available in two strengths: 100,000 IU and 300,000 IU. There is no "standard dose for everyone": the choice between them and the repeat interval start from your serum 25-OH vitamin D level and from the medical assessment. For most people, a single 300,000 IU injection covers months of intake — one more reason not to repeat it at random.
Frequently asked questions
How much does a vitamin D injection cost in Bucharest?
From 200 RON for the 100,000 IU dose at Synerva. The prices are shown above, and the medical assessment is included.
Is injectable vitamin D better than tablets?
Not across the board. It is useful mainly when a deficiency is confirmed or when a daily oral intake cannot be kept up. If your level is normal, a high dose adds nothing.
How often is it repeated?
It depends on your level and on the dose. The schedule is set individually, ideally on the basis of a vitamin D blood test.
Can it be done at home?
Yes, a nurse can come to your home in Bucharest and Ilfov, after the same assessment.
Is the vitamin D injection vitamin D3?
Yes. The form given is cholecalciferol, that is, vitamin D3 — the same form the body produces in the skin when exposed to the sun. It is given intramuscularly, in a few minutes.
What dose of vitamin D injection is given?
100,000 IU or 300,000 IU. The choice and the repeat interval start from your serum 25-OH vitamin D level and from the medical assessment — there is no dose that suits everyone.
Is the vitamin D injection given as a drip?
No. It is an intramuscular injection, not an intravenous drip. It takes a few minutes and can be done at the clinic or at home.
