1000 mL of 0.9% Sodium Chloride Injection USP (Normal Saline)
Benefits of High-Dose IV Vitamin C
This therapy delivers a high dose of vitamin C directly into your bloodstream, bypassing digestion for 100% absorption and achieving higher concentrations than oral supplements. These elevated levels support your body by:
-
Maintaining and repairing tissues through collagen synthesis
-
Transporting fatty acids into cells to generate energy via carnitine production
-
Supporting brain signaling and mood balance through neurotransmitter synthesis
-
Neutralizing harmful free radicals with antioxidant protection
-
Powering vital oxidation–reduction reactions as an enzyme cofactor
Common Reasons Patients Choose High-Dose IV Vitamin C
Wellness & Prevention
-
Antioxidant therapy for environmental toxin exposure
-
Energy support for chronic fatigue
-
Recovery enhancement after major illness or surgery
-
Immune system optimization for compromised immunity
Adjunctive Support
(Used alongside conventional medical care)
-
Lyme disease treatment support
-
Chronic infections (EBV, CMV, other viral/bacterial)
-
Mold toxicity recovery protocols
-
Post-viral syndromes (long COVID, chronic fatigue)
-
Autoimmune condition management
-
Heavy metal detoxification support
-
Cancer treatment adjunctive care
-
Chronic inflammatory conditions
Vitamin C is FDA-approved for treating vitamin C deficiency. High-dose IV vitamin C is used as adjunctive support in various therapies but is not FDA-approved to diagnose, treat, cure, or prevent other diseases. Always consult your healthcare provider before starting any new treatment program.
Risks & Side Effects
Who Should Not Have High-Dose Vitamin C IV
-
G6PD deficiency – large doses may cause hemolytic anemia
-
Kidney disease or history of kidney stones – higher chance of stone formation or kidney strain
-
Iron overload disorders (like hemochromatosis) – vitamin C increases iron toxicity risk
-
Certain anemias (sideroblastic anemia, thalassemia) — may decrease iron absorption
-
Sickle Cell Disease: High doses may precipitate crisis due to decreased blood pH
-
Severe dehydration or inability to handle fluid shifts
-
Known allergy to vitamin C preparations
-
Uncontrolled diabetes – high doses can affect blood sugar monitoring accuracy
-
On dialysis – dosing must be adjusted or avoided due to kidney clearance issues
-
Heart failure or fluid-overload conditions – extra IV fluids may worsen symptoms
-
Taking certain medications (such as warfarin) – interaction risks
-
Pregnancy & Breastfeeding - Safety has not been established
Possible Side Effects
-
Nausea or upset stomach
-
Headache or lightheadedness
-
Flushing or warmth during infusion
-
Mild pain, swelling, or redness at the IV site
-
Temporary changes in certain lab results (like blood sugar readings)
Metabolic Adaptation Warning
Long-term high doses may increase your body’s breakdown of vitamin C. Stopping abruptly after months of high-dose therapy may temporarily cause scurvy-like symptoms such as fatigue, joint pain, bleeding gums, and poor wound healing. Doses need to be tapered to prevent this.
Laboratory Testing Interference
-
Avoid vitamin C intake 48-72 hours before amine-dependent stool occult blood tests (may cause false negatives)
-
Vitamin C can interfere with urinary glucose tests that use the glucose oxidase method, potentially causing falsely low glucose readings—this is especially important for patients with diabetes
-
May affect creatinine test results, which are used to assess kidney function
