High Dose Vitamin C Therapy
Your immune system is fighting on multiple fronts, and oral supplements are not reaching therapeutic levels. Chronic illness, cancer support, and persistent infections demand concentrations that the digestive tract simply cannot deliver. SeeBeyond Medicine in Scarsdale, NY and Greenwich, CT provides high dose vitamin C therapy through intravenous infusion for direct bloodstream absorption.
Standard oral vitamin C tops out around 200 micromoles per liter in plasma. IV administration reaches concentrations 100 to 500 times higher. Our physicians calibrate each infusion to your lab results, condition severity, and treatment goals.

About This Service
What Is High Dose Vitamin C Therapy?
High dose vitamin C therapy is the intravenous administration of ascorbic acid at pharmacological concentrations, typically 25 to 100 grams per session. At these levels, ascorbic acid acts as a pro-oxidant, generating hydrogen peroxide selectively in extracellular fluid surrounding cells with low catalase activity, including many cancer cell types.
SeeBeyond Medicine delivers ascorbic acid directly into the bloodstream, bypassing the gut's absorption ceiling. The infusion achieves plasma concentrations that shift vitamin C from an antioxidant role into a pro-oxidant mechanism. This biochemical shift produces hydrogen peroxide in the tissue surrounding vulnerable cells.
Hydrogen peroxide damages cells that lack adequate catalase, an enzyme that neutralizes it. Healthy cells maintain high catalase levels and remain protected. Our integrative team uses this selective mechanism as one component within a broader, personalized treatment protocol.
Conditions Treated
Integrative Cancer Support
High dose vitamin C generates oxidative stress selectively within tumor microenvironments. SeeBeyond Medicine uses IV ascorbic acid alongside conventional oncology protocols to support immune function and reduce treatment-related fatigue. We coordinate with your oncologist to align timing and dosing.

Chronic Infections and Immune Deficiency
Persistent viral, bacterial, and fungal infections deplete circulating ascorbic acid reserves. IV delivery restores immune cell function by saturating white blood cells with the vitamin C they need for pathogen destruction. SeeBeyond Medicine pairs infusions with functional immune panels to track recovery.
Post-Surgical and Wound Healing
Ascorbic acid is a required cofactor for collagen synthesis, the structural protein behind tissue repair. Surgical patients and those with slow-healing wounds benefit from IV concentrations that oral doses cannot match. Our physicians adjust infusion frequency based on healing progress.
Chronic Fatigue and Adrenal Insufficiency
The adrenal glands contain the highest concentration of vitamin C in the body. Prolonged stress depletes those reserves and contributes to persistent exhaustion. SeeBeyond Medicine replenishes adrenal stores through targeted high dose infusions paired with adrenal function testing.
Benefits
Bypasses Digestive Limitations
Bypasses Digestive Limitations
Oral vitamin C absorption plateaus at roughly 200 milligrams per dose due to intestinal transporter saturation. IV infusion eliminates that bottleneck entirely. SeeBeyond Medicine delivers therapeutic concentrations directly to cells that need them most.
Selective Pro-Oxidant Activity
At pharmacological concentrations, ascorbic acid generates hydrogen peroxide outside cells with low catalase levels. This mechanism selectively targets vulnerable cells while sparing healthy tissue. Our physicians monitor your oxidative stress markers to optimize dosing.
Immune System Reinforcement
Neutrophils and lymphocytes require high intracellular vitamin C to produce reactive oxygen species for pathogen killing. IV therapy saturates these immune cells beyond what oral intake achieves. SeeBeyond Medicine tracks white blood cell function before and after treatment cycles.
What to Expect
Your Journey
01.
High Dose Vitamin C Therapy at SeeBeyond Medicine
1. Pre-Treatment Assessment Your protocol begins with a G6PD enzyme screening, a mandatory safety test before high dose vitamin C administration. We also assess kidney function, iron levels, and baseline oxidative stress markers. These results determine your safe starting dose. 2. IV Infusion Session Each infusion session lasts approximately 90 to 120 minutes under direct clinical supervision. SeeBeyond Medicine uses pharmaceutical-grade ascorbic acid prepared in a sterile compounding environment. Your dose gradually increases across sessions as tolerance is confirmed. 3. Monitoring and Protocol Adjustment Follow-up labs measure plasma ascorbic acid levels, inflammatory markers, and organ function after each treatment block. Your physician adjusts dose, frequency, and complementary therapies based on measurable outcomes. This iterative process ensures your protocol matches your body's response.

What Our Patients Say
Patient Experiences with High-Dose Vitamin C Therapy
Real stories from patients who found answers.
Patients who receive high-dose vitamin C infusions at SeeBeyond Medicine frequently describe the experience as calm and well-supported — a comfortable IV session with staff who monitor them closely and a physician who explains how the therapy fits into their broader care plan. Many appreciate that dosing is individualized and that the treatment is coordinated alongside, not in place of, their other medical care.
Responses to high-dose vitamin C vary with each patient's diagnosis, treatment goals, and overall health, and the therapy is used as supportive care within established clinical guidelines. SeeBeyond Medicine evaluates every patient individually and reviews suitability, including G6PD status, before beginning treatment.
Frequently Asked Questions
Common Questions
Why can't I just take oral vitamin C supplements instead?
Intestinal absorption limits oral vitamin C to plasma levels of roughly 200 micromoles per liter. IV administration bypasses the gut and achieves concentrations 100 to 500 times higher. SeeBeyond Medicine uses IV delivery specifically because these pharmacological levels activate pro-oxidant mechanisms that oral doses cannot trigger.
What is G6PD screening, and why is it required?
G6PD (glucose-6-phosphate dehydrogenase) deficiency is a genetic enzyme condition that affects red blood cell stability. Patients with this deficiency risk hemolytic anemia when exposed to high dose ascorbic acid. SeeBeyond Medicine screens every patient before the first infusion to ensure safety.
Is high dose vitamin C therapy safe during chemotherapy?
Timing coordination with your oncologist is essential. Research suggests IV vitamin C may reduce certain chemotherapy side effects without interfering with treatment efficacy when administered on non-chemo days. SeeBeyond Medicine works directly with your oncology team to develop a safe schedule.
How many sessions will I need?
Session count depends on your condition, severity, and treatment response. Cancer support patients at SeeBeyond Medicine typically receive two to three infusions per week during active protocols. Immune support and recovery patients often start with weekly sessions and taper based on lab results.
Does insurance cover high dose vitamin C therapy?
Coverage varies by carrier and diagnosis. Our patient coordination team provides documentation and assists with reimbursement for medically indicated infusions.
