Vitamin C IV / Ascorbic Acid Infusion
Intravenous administration of high-dose ascorbic acid (10–75g per session), achieving plasma levels 100–500x higher than achievable with oral supplementation.
How it works
At supraphysiological doses, Vitamin C acts as a pro-oxidant generating hydrogen peroxide selectively in cancer cells (normal cells have catalase to neutralize it). Also boosts collagen synthesis, immune cell function, and acts as a powerful antioxidant at lower IV doses.
Reported benefits
- Immune system enhancement and infection recovery
- Collagen synthesis support for skin health
- Antioxidant defense and oxidative stress reduction
- Fatigue reduction in chronic conditions
- Post-surgical healing support
- Adjunctive cancer care support (under medical supervision)
