High-dose intravenous (IV) vitamin C therapy is rapidly gaining popularity in the world of integrative and regenerative medicine. Known for its antioxidant power and immune-boosting potential, vitamin C administered through an IV allows the body to absorb levels far beyond what oral supplements can achieve.
In this 2025 guide, we break down the science behind high-dose vitamin C IV therapy, its top health benefits, clinical applications, safety, cost, and frequently asked questions.
What Is High-Dose Vitamin C IV Therapy?
This therapy involves delivering vitamin C (ascorbic acid) directly into the bloodstream via an intravenous drip. This bypasses the digestive system and allows for blood concentrations 50–100x higher than oral intake — enabling therapeutic effects such as oxidative stress reduction and immune system enhancement.
