High-Dose Vitamin C — Find Clinics Near You
High-dose vitamin C IV delivers therapeutic levels of ascorbic acid far beyond what oral supplements can achieve — supporting immune function and antioxidant activity.
The recommended daily intake for vitamin C is 65–90mg. High-dose IV vitamin C therapy delivers 10–75 grams — 100x or more the daily recommendation. At these concentrations, vitamin C acts as a pro-oxidant rather than an antioxidant, generating hydrogen peroxide in tissue that can selectively target abnormal cells.
High-dose vitamin C has been studied extensively, particularly in oncology and immune support contexts. It cannot be achieved through oral supplementation — doses above 2–3g orally cause GI distress, so the IV route is the only practical delivery method for therapeutic concentrations.
