High-Dose Vitamin C IV.

What it is

High-dose vitamin C IV delivers ascorbic acid straight into the bloodstream, reaching blood levels far higher than any oral dose can. Infusions often range from 25 to 100 grams. In lab studies, vitamin C at these levels produces hydrogen peroxide, which can damage cancer cells while sparing healthy ones.

It is used most in integrative cancer care, always alongside standard treatment, and also for fatigue, recovery and ongoing infections. Small human studies suggest it can improve quality of life and ease some chemotherapy side effects. Whether it helps treat cancer itself is still being studied.

What happens at a visit

1. Lab work first, including a G6PD test and kidney function.
2. An IV placed and a slow infusion over 60 to 120 minutes.
3. You may feel warmth, thirst or a need to urinate during the drip.
4. Fluids before and during treatment to keep you hydrated.
5. Some people feel more energy afterward, and some feel tired for a bit.
6. A series of infusions, with timing set by your clinician.

Who it is for

• People with cancer seeking integrative care, with their oncologist's approval
• People going through chemotherapy who want support with side effects
• People with chronic fatigue
• People with Lyme disease or long-running infections, alongside their treatment
• People recovering from illness or surgery

Evidence and safety

The evidence is early but encouraging: small human trials suggest it can improve quality of life and ease some chemotherapy side effects, while whether it slows cancer itself hasn't been settled in large trials. It is generally well tolerated after screening. A G6PD test is essential first, and it isn't suitable for people with kidney disease or a history of kidney stones. Use it only alongside standard cancer care, coordinated with your oncologist.
