Benefits
Antioxidant
Vitamin C neutralises free radicals and supports the body's antioxidant balance.
Immune support
It has a recognised role in the normal function of the immune system.
Support for collagen
Vitamin C is involved in collagen synthesis — relevant for skin and tissues.
High bioavailability
The high intravenous dose goes beyond the intestinal absorption limit of oral vitamin C.
Quick administration
The protocol takes about 30 minutes.
Can be combined
It can be combined with glutathione for a complete antioxidant protocol.
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.

What a high-dose vitamin C IV drip is
A vitamin C IV drip delivers a high dose (5000 mg) intravenously, straight into the bloodstream. By mouth, the absorption of vitamin C is limited — the body eliminates the excess. The intravenous route goes beyond this threshold, which is why it is preferred when the aim is bioavailable antioxidant intake.
At Synerva, in Bucharest, the vitamin C IV drip is chosen for antioxidant and immune support and for supporting collagen production. Honestly: it is not a treatment for a condition and does not replace a balanced diet — the benefit is supportive, after an assessment.
How a session works
1. The assessment
A doctor discusses your goal, your medical history and your tolerance. The assessment is included and checks whether the high dose is suitable for you.
2. The administration
The drip takes about 30 minutes. You can relax, read or work during the administration.
3. After the session
For longer-term goals, vitamin C can be planned as a course, possibly combined with glutathione.
"Injectable vitamin C" or "vitamin C for infusion" — what it actually means
You may have searched for "injectable vitamin C", "vitamin C for infusion" or "intravenous vitamin C" and be wondering whether these are different things. They are not: they all describe the same route of administration, straight into the bloodstream, bypassing intestinal absorption.
The practical difference is one of rate. An injection delivers a small amount quickly; at Synerva high-dose vitamin C is given as a slow drip, over about 30 minutes, for tolerance and comfort. Whatever term brought you here, the procedure is the same.
If you have seen vitamin C ampoules at the pharmacy and are wondering what they contain and at what doses they are used, we cover this separately in vitamin C ampoules — leaflet, doses and IV drips.
Pascorbin, vitamin C ampoules and the IV drip at the clinic
Many people arrive here after coming across injectable vitamin C under a brand name, most often Pascorbin, or after seeing vitamin C ampoules at the pharmacy. The substance is the same in all of them: ascorbic acid. The concentration and packaging differ from one manufacturer to another, so the real dose is read from the product leaflet, not from the name.
For doses in the gram range, the ampoule is not injected as it is. It is diluted in an infusion solution and given slowly — exactly what we do with the 5000 mg dose, over about 30 minutes, after an assessment. We do not sell ampoules and we do not recommend self-administering an injectable.
For daily intake, vitamin C tablets from the pharmacy are, in most cases, enough — we say so even though we give the other option. The IV drip has only one certain advantage: it bypasses the intestinal absorption ceiling and reaches blood concentrations that no oral dose can reach.
How much does injectable vitamin C cost — prices in Bucharest
At Synerva, high-dose injectable vitamin C (5000 mg) costs 300 RON, with the medical assessment included. The combination with glutathione, for complete antioxidant intake, is 450 RON. There is no separate consultation fee and no extra cost for materials.
The price is the same at the clinic and at home in Bucharest and Ilfov, where only the travel fee is added. All the options are shown above.
The benefits of injectable vitamin C — what it supports and what it doesn't
Vitamin C has recognised roles in the normal function of the immune system, in antioxidant protection and in collagen synthesis. By mouth, absorption is limited by an intestinal threshold: above a certain amount, the excess is eliminated. Intravenous administration bypasses this threshold — hence the logic of the high dose.
What it doesn't do: it is not a treatment for any condition, it does not prevent or cure colds, and it does not replace a balanced diet. It is supportive intake, given after a medical assessment.
Administration: how a vitamin C IV drip is given
The session starts with inserting a cannula, as for a blood test. The vitamin C is then delivered in fluids, slowly, over about 30 minutes. You can read or work during the administration, and afterwards you can go back to your activities straight away.
No special preparation is needed — you can eat normally beforehand. It is given only by medical staff, with monitoring throughout the session.
Contraindications — who it is not given to
High-dose vitamin C is not given to people with G6PD deficiency, in whom it can cause haemolysis. With known kidney conditions or a history of kidney stones, it is given only after a medical assessment, because high doses increase oxalate excretion.
Pregnancy, breastfeeding, current medication and any history of allergic reactions are discussed at the assessment. If your details show that the high dose makes no sense, we tell you — including when oral intake is enough.
Who it is suitable for
The vitamin C IV drip is chosen by people who want antioxidant and immune support, or support for their skin and collagen. The high intravenous dose requires a prior assessment — certain conditions (kidney conditions, for example) call for caution.
We tell you honestly when the high dose makes sense and when oral intake is enough — the recommendation starts from your details, not from a sale.
Frequently asked questions
How much does a vitamin C IV drip cost in Bucharest?
From 300 RON for the 5000 mg dose at Synerva. The prices are shown above, and the medical assessment is included.
Can I have the IV drip if my veins are hard to find?
Most of the time, yes — tell us from the start, when you book. It helps a lot to drink water in the hours before and not to arrive cold: in a hydrated, warm body the veins are easier to see and feel. The cannula is usually placed on the forearm or the back of the hand, by medical staff used to finding veins. If it cannot be placed comfortably and safely, we do not keep trying with repeated needle sticks, and we discuss the right option with you.
What does high-dose intravenous vitamin C do?
It supports antioxidant balance, the immune system and collagen synthesis, with higher bioavailability than the oral form. It is not a treatment for a condition.
How long does it take?
About 30 minutes for the basic protocol.
Can it be done at home?
Yes, a nurse can come to your home in Bucharest and Ilfov, after the same assessment.
Are "injectable vitamin C" and "vitamin C for infusion" the same thing?
Yes, both terms describe administration straight into the bloodstream. At Synerva it is given as a slow drip, over about 30 minutes, not as a quick injection.
Who should not have injectable vitamin C?
People with G6PD deficiency. With kidney conditions or a history of kidney stones, only after a medical assessment. All of this is checked at the included assessment.
How often can it be done?
It depends on your goal and on the doctor's recommendation at the assessment. For longer-term goals it is planned as a course, possibly combined with glutathione.
What is Pascorbin and what does it have to do with your IV drip?
Pascorbin is a brand name for injectable vitamin C, that is, ascorbic acid. At Synerva the same substance is given, vitamin C 5000 mg, diluted in a slow drip of about 30 minutes, by medical staff, after an assessment. We do not sell ampoules.
Does it prevent colds?
No. Vitamin C has a recognised role in the normal function of the immune system, but intravenous administration does not prevent or treat respiratory infections.
Do I need blood tests beforehand?
Not always. At the assessment, the doctor decides whether they are needed, depending on your medical history — especially for kidney function.

Limitation: Only 7 young, healthy men, hospitalised for 4–6 months on a diet without vitamin C. The study is of the oral route. Tissue saturation at low doses also shows that, in a person without a deficiency, it has not been demonstrated what a high IV dose adds.
