What supplements should I avoid during Leukemia treatment

Supplements to Avoid During Leukemia Treatment

This is an important question, and I appreciate you asking it. However, I need to be direct with you: the NCCN Guidelines for Patients on leukemia treatment don't provide a specific list of supplements to avoid.

Here's what I can tell you based on the available guidelines:

What the Guidelines Say

According to the NCCN Guidelines for Patients: Acute Myeloid Leukemia (2025), when discussing your medical history, you should:

"Bring a list of old and new medicines and any over-the-counter (OTC) medicines, herbals, or supplements you take. Some supplements interact with and affect medicines that your care team may prescribe."

This tells us that supplements CAN interact with leukemia treatments, but it doesn't specify which ones.

Why This Matters

The reason your care team needs to know about supplements is that:

• Some supplements can interfere with how chemotherapy or targeted therapy works
• Others may increase bleeding risk (important since leukemia already affects clotting)
• Some may interact with supportive care medications
• Certain supplements can stress the liver or kidneys during treatment

What You Should Do

Before taking ANY supplement—including vitamins, herbal remedies, or over-the-counter products—you need to discuss it with your oncology team. This includes:

• Vitamin supplements
• Herbal products (like ginger, turmeric, St. John's Wort)
• Dietary supplements
• Even "natural" or "safe" products

Questions to Ask Your Care Team

1. "I'm currently taking [list supplements]. Are any of these safe to continue during my treatment?"
2. "Are there specific supplements I should avoid during chemotherapy/targeted therapy?"
3. "Should I stop all supplements before starting treatment, or can some continue?"
4. "Are there supplements that might help with side effects that are safe for me?"
5. "When can I resume supplements after treatment ends?"

Your oncologist, pharmacist, or nutritionist on your care team can review your specific supplements against your specific treatment plan and give you personalized guidance.
