What supplements should I avoid during Lung Cancer treatment

Supplements to Discuss With Your Lung Cancer Care Team

This is an important question, and I appreciate you asking it. However, I need to be direct: I cannot recommend which specific supplements to avoid because this depends entirely on your individual treatment plan, other medications, and your oncologist's assessment.

Why This Matters

Certain supplements can interfere with lung cancer treatments in significant ways:

• Antioxidants (like high-dose vitamins C, E, and selenium) may potentially reduce the effectiveness of some chemotherapy and radiation therapy, which work partly by creating oxidative stress in cancer cells
• Herbal supplements (St. John's Wort, ginkgo biloba, garlic supplements) can interact with targeted therapies and immunotherapies
• Blood thinners (like high-dose vitamin E or fish oil) may increase bleeding risk, especially important if you're on certain medications
• Supplements affecting the immune system may interact with immunotherapy treatments

What You Should Do

Before taking ANY supplement—including vitamins, herbs, or over-the-counter products—discuss with your oncology team:

1. What supplements am I currently taking? (Bring a complete list, including doses)
2. Are there any supplements I should stop before starting treatment?
3. Which supplements are safe during my specific treatment plan?
4. Should I take a basic multivitamin, or should I avoid all supplements?
5. Are there any interactions between my supplements and my chemotherapy/targeted therapy/immunotherapy?

Your oncologist and pharmacist have access to your complete treatment regimen and can give you personalized guidance that I cannot provide.
