High-Dose Vitamin C IV Therapy Bend, Oregon

If you're looking for a high-dose vitamin C IV in Bend, Oregon, Flow Wellness offers physician-led ascorbic acid infusions from 10 to 75 grams, with G6PD screening, clear pricing, and dosing guided by a medical team you can trust.

What is high-dose Vitamin C?

High-dose vitamin C is ascorbic acid delivered directly into the bloodstream at doses far above what supplements or food can provide, typically 10 to 100 grams per infusion. At these levels vitamin C behaves differently than it does at nutritional doses. It helps your body:

  • Reach blood concentrations only achievable by IV, because oral absorption plateaus at roughly 200 mg per hour
  • Support immune cell function and collagen synthesis
  • Act as an antioxidant at ordinary doses and, at pharmacologic doses, generate hydrogen peroxide in tissue, which is the basis for its use as a supportive therapy in research settings

Pharmacologic ascorbate is an active area of research in supportive oncology care, sepsis, and recovery. The evidence is clearest for safety and for quality-of-life outcomes; larger trials on disease outcomes are still underway.

Why IV instead of oral Vitamin C?

Your intestine tightly controls how much vitamin C enters the blood. Even 3 grams by mouth every four hours produces peak blood levels around 220 micromolar. A single 50-gram IV can produce levels 30 to 70 times higher. If your goal is simply to prevent deficiency, oral vitamin C is enough. If your goal is the higher blood levels studied for immune, recovery, and supportive care, only IV gets you there.

Why add high-dose Vitamin C to your routine?

If you're already investing in your health through IV nutrient therapy, hormone optimization, or a longevity plan, high-dose vitamin C may be a useful addition, especially when your goals include resilience, recovery, and feeling well through a demanding season.

1) Immune support during high-demand seasons

Vitamin C is concentrated in white blood cells and consumed rapidly during illness and stress. Patients often schedule infusions ahead of travel, ski season, race training, or when a cold is going around the household. Individual response varies.

2) Recovery from illness, surgery, and hard training

Collagen synthesis, tissue repair, and oxidative stress recovery all depend on adequate vitamin C. Higher blood levels may support recovery when demand outpaces what diet supplies.

3) Energy and quality of life

The most consistent finding in clinical studies of IV vitamin C is improvement in fatigue and overall quality of life, particularly in people under significant physical stress. Many patients describe feeling steadier and more resilient after a course.

4) Skin, collagen, and antioxidant support

Vitamin C is required to build collagen. Patients pairing high-dose vitamin C with glutathione often do so for skin brightness and antioxidant support.

5) Supportive care alongside medical treatment

High-dose IV vitamin C has been studied as an adjunct during cancer treatment, where research suggests benefit for fatigue, appetite, and treatment tolerance. It is supportive, not a treatment for cancer, and we coordinate with your oncology team before scheduling.

How is high-dose Vitamin C given at Flow Wellness?

  • Screening first. A one-time G6PD blood test and kidney-function check before any dose of 15 grams or more. This can be drawn at our Bend clinic.
  • Pharmaceutical-grade ascorbic acid, preservative-free and buffered, diluted in sterile water or lactated Ringer's rather than saline to keep the infusion comfortable.
  • Magnesium added to reduce vein irritation and cramping, with other nutrients available as add-ons.
  • Slow, monitored infusion. Rates stay under one gram per minute. Plan on 45 minutes for 25 g, about 90 minutes for 50 g, and 2 to 3 hours for 75 g.
  • Titration. Most patients start at 15 to 25 g and step up over subsequent visits. For therapeutic protocols we can draw a post-infusion vitamin C level to guide dosing.

High-dose Vitamin C IV Infusion

Our premier immune and recovery infusion

What does a high-dose Vitamin C infusion feel like?

Most people feel little during the infusion beyond coolness at the IV site. Some notice mild nausea, lightheadedness, or vein tenderness, which usually resolves if we slow the drip. Thirst is common, so we encourage water before, during, and after. Afterward, many patients describe feeling calm and steady rather than stimulated.

How often should I get high-dose Vitamin C?

  • For immune and wellness support: a single 10–25 g infusion before travel or during a high-exposure season, or every 2–4 weeks for ongoing support
  • For recovery: 25–50 g once or twice weekly for 2–4 weeks, then as needed
  • For physician-directed therapeutic protocols: 50 g one to three times weekly for a defined course, with periodic kidney-function rechecks
  • As an add-on: lower doses of vitamin C can be paired with a Myers cocktail, glutathione, or NAD+ in the same visit

Who may be a good candidate?

People commonly ask about high-dose vitamin C if they're experiencing:

  • Frequent colds or a slow rebound after getting sick
  • Recovery from surgery, injury, or an intense training block
  • Persistent fatigue during a demanding stretch of life
  • Interest in supportive care alongside medical treatment, in coordination with their specialist

Not sure if you're a fit? If you're in Bend, Oregon, we can help you decide between a standard vitamin C add-on and a high-dose infusion based on your goals and health history. Contact Flow Wellness to get started.

Who should not get high-dose Vitamin C?

We screen every patient before the first high-dose infusion. High-dose vitamin C is not appropriate for people with:

  • G6PD deficiency (risk of red blood cell breakdown), which is why we test before dosing
  • Kidney disease, kidney failure, or dialysis
  • A history of oxalate kidney stones
  • Hemochromatosis or iron overload
  • Pregnancy, where high doses are generally deferred

If you have diabetes, one more thing to know: vitamin C causes fingerstick glucose meters to read falsely high for several hours after an infusion.

Frequently asked questions about high-dose Vitamin C

How much vitamin C is in a high-dose IV?

High-dose vitamin C IVs at Flow Wellness range from 10 grams to 50 grams of ascorbic acid per infusion. For comparison, a typical oral supplement is 0.5 to 1 gram. The dose is chosen by your clinician based on your goals, lab results, and how you responded to earlier infusions.

Do I need a G6PD test before a vitamin C IV?

Yes. Before any infusion of 15 grams or more, we require a G6PD blood test. People with G6PD deficiency can develop red blood cell breakdown (hemolysis) after high-dose vitamin C. We also check kidney function. This is a one-time screen and can be drawn in our Bend clinic.

How often can you get a vitamin C IV?

Most patients using high-dose vitamin C for immune or recovery support come in weekly to every few weeks. Patients on a therapeutic protocol may infuse 1 to 3 times per week for a defined course. Your clinician sets the schedule and rechecks kidney function periodically on ongoing plans.

Does IV vitamin C work better than oral vitamin C?

For reaching high blood levels, yes. The gut limits how much oral vitamin C is absorbed, so blood levels plateau even at large oral doses. IV administration bypasses that limit and can produce blood concentrations many times higher than oral dosing. Whether those higher levels translate to a benefit depends on the goal, and the evidence is strongest for supportive uses such as energy, recovery, and quality of life.

Is high-dose vitamin C safe?

For screened, well-hydrated adults with normal kidney function, high-dose IV vitamin C has a good safety record in clinical studies. The main risks are hemolysis in people with G6PD deficiency, kidney stones or kidney strain in people with kidney disease or a stone history, and falsely elevated fingerstick glucose readings for several hours after the infusion. Screening addresses the first two; we counsel diabetic patients on the third.

What does a vitamin C infusion cost in Bend?

High-dose vitamin C IVs are $249 for 10–25 g ($189 for members) and $349 for 50 g($289 for members). The G6PD screening lab is $20, drawn once. There are no hidden fees.

Can high-dose vitamin C be used during cancer treatment?

High-dose IV vitamin C is studied as a supportive therapy alongside conventional cancer care, with research suggesting it may help with fatigue, quality of life, and treatment side effects. It is not a cancer treatment and does not replace oncology care. If you are in active treatment, we coordinate with your oncologist on timing and dosing before scheduling.
