High Dose Vitamin C IV
"I want powerful antioxidant support — and I've heard high-dose IV Vitamin C can do things oral supplements simply cannot."

300x more than your normal level. Delivered by IV.

High-dose Vitamin C IV at therapeutic concentrations (350–400 mg/dL) — far beyond anything oral supplementation can achieve. Used for oxidative stress, inflammatory conditions, cancer support, Lyme disease, and immune restoration where oral Vitamin C has no meaningful effect.

What it treats

At therapeutic IV doses, Vitamin C does things that are biologically impossible to achieve orally.

The site is explicit: 350–400 mg/dL is the concentration needed for cancer cell disintegration — more than 300x your normal level. Oral delivery cannot produce this. IV delivery can.

🎗️
Cancer Support & Complementary Treatment

At concentrations of 350–400 mg/dL — achievable only by IV — Vitamin C affects cancerous cells while sparing healthy ones. Unlike chemotherapy and radiation, which contribute to oxidative stress and break down Vitamin C in the process, high-dose IV Vitamin C is less toxic to the body and works as a powerful complementary treatment. It is not a guaranteed cure, but it is a meaningful addition to a conventional treatment plan.

🦟
Lyme Disease Support

Research has shown that high-dose IV Vitamin C can treat inflammatory and oxidative stress-related conditions including Lyme disease. Its antioxidant action neutralizes the excess free radicals that drive the inflammatory cascade in Lyme — supporting the body's natural recovery process alongside antibiotic treatment.

🔥
Oxidative Stress & Free Radical Damage

Free radicals damage cells and cause oxidative stress — the underlying mechanism behind aging, heart disease, cancer, autoimmune diseases, and neurodegenerative disorders. Vitamin C at IV doses floods the body with enough antioxidants to neutralize excess free radicals before they cause further damage. The body cannot produce its own Vitamin C — IV therapy provides what injured tissue needs at the concentration it requires.

💊
Chemotherapy & Radiation Support

Traditional cancer treatments like radiation and chemotherapy contribute to oxidative stress and deplete Vitamin C — causing additional cellular damage alongside their therapeutic effect. High-dose IV Vitamin C is a natural complement: it supports the body's antioxidant defenses during treatment, helps healthy cells withstand oxidative damage, and supports recovery between sessions.

🛡️
Immune Restoration & Illness Recovery

At IV doses, Vitamin C directly stimulates white blood cell production, supports interferon production, and activates the cytokine signaling that coordinates immune response. For patients recovering from serious illness, chronic infection, or prolonged immune depletion, IV Vitamin C delivers the immune surge that oral supplementation at any dose cannot produce.

🌿
Inflammatory & Autoimmune Conditions

Vitamin C at pharmacological IV concentrations has a direct anti-inflammatory effect — inhibiting NF-κB, a central regulator of inflammatory gene expression. Used as a complementary treatment for a range of inflammatory and autoimmune conditions where oxidative stress is a primary driver of ongoing tissue damage.

There is no oral dose of Vitamin C that produces what IV delivers. The dosage and delivery method are the whole point.

High-dose IV Vitamin C therapy is affordable relative to traditional treatments, less toxic than many conventional approaches, and can be added to any existing treatment plan. A consultation with our physician will determine whether it is appropriate for your specific situation.

High dose Vitamin C IV mechanism at IUVENTUS Medical Center
How it works

The oral limit is 2g. IV delivers 25g.

The therapeutic mechanism of high-dose IV Vitamin C depends entirely on the concentration achieved. At 350–400 mg/dL — more than 300 times the normal blood level — Vitamin C produces a pro-oxidant effect specifically in cancerous cells and pathogens while antioxidant enzymes (catalase) protect healthy cells. This selective toxicity is the key distinction from chemotherapy, which damages both healthy and cancerous tissue indiscriminately. Studies have confirmed that oral delivery cannot produce high enough concentrations to trigger this effect — IV delivery is the only method that achieves the therapeutic threshold.

An interesting parallel exists in nature: injured animals start producing more Vitamin C to trigger fast regeneration. Human bodies lack this ability — but IV therapy can replicate the effect externally, providing the antioxidant surge that injured or diseased tissue requires. For Lyme disease and cancer specifically, the oxidative stress driving cellular damage can be directly counteracted at these concentrations in ways that feel more like supporting the body's own defenses than imposing a foreign treatment.

Who should consider high-dose IV Vitamin C

Cancer patients seeking complementary support alongside conventional treatment · Lyme disease patients with significant inflammatory component · Patients recovering from chemotherapy or radiation · Chronic oxidative stress or inflammatory conditions · Immune depletion after serious illness. Note: always coordinate with your oncologist or treating physician if you have an active cancer diagnosis.

The research is clear

The dosage is everything. And only IV achieves it.

The difference between oral and IV Vitamin C is not quantitative — it is qualitative. At 350–400 mg/dL, achieved only by IV, mechanisms activate that are biologically impossible at oral concentrations. The research behind high-dose IV Vitamin C has been accumulating since the 1970s.

Consultation & Assessment

We assess your immune history, current illness status, medications, and any contraindications — particularly G6PD deficiency, which is a contraindication for high-dose Vitamin C. We determine the appropriate dose for your situation.

02
💉
IV Infusion (45–60 min)

10–25g administered over 45–60 minutes depending on dose and tolerance. A mild cooling sensation and temporary diuretic effect are common. Most patients feel an energy shift during or after the session.

03
📆
Protocol Frequency

For acute illness or prevention before high-risk exposure: 1–2 sessions clustered. For chronic inflammation or ongoing immune support: monthly. Often combined with glutathione IV in the same session for enhanced antioxidant benefit.

Why Choose Us

Medicine that
gets you.

G6PD screening before high-dose Vitamin C is a non-negotiable safety step that not all providers perform. We do.

01

G6PD Screening Before High Doses

G6PD (glucose-6-phosphate dehydrogenase) deficiency is a contraindication for high-dose IV Vitamin C — it causes hemolytic anemia in affected patients. We screen for this before administering doses above 10g. Many providers skip this step. We don't.

02

Dose Matched to Indication

10g for general immune maintenance. 15–25g for acute illness support, post-viral protocols, or anti-inflammatory goals. We don't use a single dose for all patients.

03

Combined With Glutathione

High-dose Vitamin C and glutathione work synergistically — Vitamin C regenerates oxidized glutathione, and glutathione protects against the oxidative byproducts of high-dose Vitamin C. We commonly administer both in the same session.

04

Monitoring Kidney Function

High-dose Vitamin C increases urinary oxalate excretion. For patients with kidney stones or impaired kidney function, we monitor and adjust doses accordingly. Adequate hydration before and after the session is standard protocol.

Common Questions

Everything you
want to know.

It is a complementary treatment — not a guaranteed cure or a replacement for conventional cancer care. At therapeutic IV concentrations (350–400 mg/dL), Vitamin C produces a pro-oxidant effect that causes cancer cells to disintegrate while leaving healthy cells protected by their natural antioxidant enzymes. This makes it less toxic than chemotherapy and radiation, which damage healthy tissue alongside cancerous tissue. It is best added to an existing treatment plan — your physician will advise whether it is appropriate for your specific cancer type and treatment protocol.
Many patients report a surge in energy and mental clarity during or shortly after the infusion. For immune or anti-inflammatory goals, effects typically develop over 24–72 hours. For acute illness support, many patients notice improved symptoms within 12–24 hours of treatment.
The difference is pharmacokinetic, not just quantitative. Oral Vitamin C is limited to approximately 1–2g of absorbed dose before GI tolerance limits further intake. At these doses, Vitamin C functions as a nutritional antioxidant. At IV doses of 10–25g, plasma concentrations enter a pharmacological range where different mechanisms activate — including pro-oxidant activity against pathogens and potent anti-inflammatory signaling. These mechanisms do not occur at oral doses regardless of how much you take.
High-dose Vitamin C increases urinary oxalate, which is a risk factor for calcium oxalate kidney stones. If you have a history of kidney stones, we adjust the dose, ensure adequate hydration before and after the session, and monitor kidney function. This is not an absolute contraindication but requires modification of the standard protocol.
Yes. High-dose IV Vitamin C is used for Lyme disease because Lyme produces significant inflammatory and oxidative stress that can persist despite antibiotic treatment. The antioxidant capacity of IV Vitamin C at therapeutic doses helps neutralize the free radical cascade that drives ongoing Lyme-related symptoms. It is used as a complementary treatment alongside conventional Lyme protocols, not as a replacement for antibiotics.
