IV therapies
High-Dose Vitamin C
An infusion service with treatment-specific assessment and screening.
Start with a consultationA closer look
IV vitamin C delivers vitamin C into a vein and produces different blood levels from taking it by mouth. That difference does not establish a benefit for every suggested use.
How it works & what research shows
Why this route may fit your needs
IV achieves blood concentrations that oral vitamin C cannot reach. This is a pharmacologic distinction studied in clinical research, not proof of better general wellness or a cancer cure.
The route must match the prescribed product. Oral options, injection-site risks and your individual health needs are part of the decision.
Mechanism
Vitamin C supports collagen formation and antioxidant reactions. At the much higher concentrations achieved by IV administration, researchers also study pro-oxidant effects, including hydrogen-peroxide generation, in experimental cancer settings.
Clinical benefits & evidence
Correcting vitamin C deficiency is an established clinical use of vitamin C. Benefits of high-dose IV treatment for general wellness are not established. Small oncology studies have explored symptoms and quality of life, but results do not justify replacing standard treatment.

Research & unanswered questions
Research examines high-dose IV vitamin C alongside conventional cancer therapies, including which patients might benefit and how treatments interact. Laboratory effects and early studies need confirmation in rigorous clinical trials; this research does not describe an oncology service offered by Vitara.

Is this right for you?
Clinical review should include the reason for treatment, kidney health, a history of kidney stones, medicines, and screening for G6PD deficiency where appropriate.
Your visit
What to expect
Your clinician will explain the recommended treatment, alternatives, and follow-up before you decide whether to proceed.
Before your visit
Personalized preparation instructions will be provided through the patient platform once appointments are available.
After your visit
Treatment-specific aftercare instructions will be provided by the clinical team through the patient platform.
Risks & important considerations
High doses can cause serious harm in people with certain kidney conditions or G6PD deficiency. Vitamin C can also interfere with some glucose measurements. This is not a complete risk list.
How we reduce risk
Our approach is outlined below. These measures reduce risk but cannot eliminate it.
- Screen for G6PD deficiency before high-dose treatment, and review kidney function, kidney-stone history, and iron-overload conditions. Avoid treatment when screening identifies an unacceptable risk.
- Review medicines and current treatments for possible interactions, and assess whether the infusion’s fluid load is appropriate.
- Identify glucose-testing devices or laboratory methods that vitamin C may interfere with, and coordinate an appropriate testing plan with the treating team.

Understanding the evidence
Evidence depends on the condition being studied. Research in specific medical settings should not be generalized to routine wellness, immunity, or anti-aging benefits. IV vitamin C is not a substitute for established care.

Common questions
Can I book this treatment now?
Yes. Every visit starts with a consultation, which you can book online from our patient care page.
Where will I complete my medical forms?
Medical intake, consent forms, and patient records will be handled in a separate patient platform. This website does not collect that information.
