IV Vitamin C High Dose

High-dose vitamin C infusion for immune support and skin brightening.

High-dose vitamin C IV therapy delivers concentrated ascorbic acid directly into your bloodstream, bypassing the digestive system’s absorption limits. Oral vitamin C supplements max out at roughly 200 mg of absorption per dose, but intravenous delivery can achieve blood levels 50–100 times higher. At these concentrations, vitamin C acts as a potent antioxidant, supporting immune function, collagen synthesis, and cellular repair. Many longevity-focused clinics offer vitamin C infusions as part of wellness protocols, combining it with other nutrients for synergistic effects. Sessions typically last 30–60 minutes depending on the dose. You’ll be seated comfortably while a licensed nurse or doctor administers the infusion through a small IV catheter. Some people report a pleasant warming sensation or mild citrus taste during the infusion — both are normal. Most patients feel energized afterward, though individual responses vary.
