High Dose IV Vitamin C: Answers to 3 FAQs

Citrus fruits are rich in vitamin C. IV vitamin C therapy is another way to make sure you're getting enough.

1. What is the difference between a vitamin C tablet and IV vitamin C?

This is a common question I get from patients because vitamin C tablets are easy to pick up from stores. The main difference between a tablet and IV is the dose of vitamin C that can be administered. Absorption of vitamin C taken by mouth is limited by the gut, which can be an issue when gut health is not at its best.

2. What are the risks and benefits of IV vitamin C therapy?

While IV vitamin C therapy is generally safe, it is always important to consider the risks and benefits. Vitamin C offers a variety of benefits including strengthening the immune system to fight viruses and bacteria and providing the body with antioxidant support to reverse signs of aging.

IV vitamin C is not for everyone. For example, individuals with a G6PD deficiency have difficulty tolerate high does of vitamin C. Our doctors will discuss the risks and benefts as it specifically pertains to you.

3. How long does IV vitamin C therapy take?

The answer to this question will vary from person to person and can range from weekly to monthly sessions to get the most benefit. Each session can last between 60-90 minutes depending on the strength of vitamin C in the IV.
