High Dose Vitamin C

Vitamin C at therapeutic concentrations — a different category entirely

Oral Vitamin C is limited by intestinal absorption — most people can absorb only 200–500mg before the excess is excreted. Intravenous Vitamin C bypasses this ceiling entirely, achieving plasma concentrations 50–100 times higher than oral supplementation can produce.

At these concentrations, Vitamin C acts as a powerful pro-oxidant in addition to its antioxidant role — selectively generating hydrogen peroxide in cancer cells while leaving healthy tissue unharmed. It also plays a critical role in collagen synthesis, immune cell production, and the regeneration of other antioxidants including glutathione and Vitamin E.

At HydraSpa, our High Dose Vitamin C infusion is used for general immune support, anti-aging protocols, and as part of our integrative oncology program. Each session is clinically supervised and customized to your health history and goals.

Common questions

What dose of Vitamin C is in this infusion?

Our standard High Dose Vitamin C infusion delivers 15–25g of Vitamin C. For integrative oncology protocols, doses of 25g, 50g, and 75g are available. The appropriate dose is determined based on your health history and goals.

Is high dose Vitamin C IV safe?

Yes, for most people. All patients are required to complete lab work and receive medical clearance before their first High Dose Vitamin C infusion. We screen for G6PD deficiency, as this enzyme deficiency can cause adverse reactions at high doses. Our clinical team reviews your health history at every visit.

How long does the infusion take?

A 15–25g infusion takes approximately 60–90 minutes. Higher doses used in oncology protocols (50–75g) take 2–3 hours and are administered at a controlled rate.

How does IV Vitamin C differ from oral Vitamin C?

Oral Vitamin C is limited to approximately 200–500mg of absorption before the excess is excreted. IV Vitamin C achieves plasma concentrations 50–100 times higher, enabling therapeutic effects that oral supplementation simply cannot produce.

Can I use High Dose Vitamin C alongside chemotherapy?

Many integrative oncology patients use high-dose IV Vitamin C alongside conventional treatment. We work collaboratively with your oncology team and require your current treatment summary before beginning a cancer support protocol.
