IV Vitamin C is one of the most talked-about integrative cancer therapies worldwide. From reducing side effects of chemo to potentially playing a role in long-term recurrence prevention, the buzz is everywhere.

But does it actually work? Is it safe? And how do you know if it’s right for you?

In this episode of The Flourish After Cancer Podcast, I unpack the science, protocols, and practicalities of IV Vitamin C — so you can make informed, confident choices about your recovery and health.

⚠️ This is a must-listen if:

• You’ve heard about IV Vitamin C and wonder if it’s evidence-based or just hype
• You want to know the difference between oral, low-dose, and high-dose IV Vitamin C

💊 In this episode, you’ll learn:

• The unique mechanism of action that makes high-dose IV Vitamin C different from oral
• Oral vs IV Vitamin C — why the route matters

• What research says about treatment protocols (frequency & duration)
• The safety checks every patient should have before starting
• Benefits during cancer treatment
• Benefits after cancer treatment
• Side effects & what to watch for

💡 You’ll leave this episode with:
