Which supplements should be avoided with lymphoma?
Some supplements can interfere with lymphoma treatment or cause complications. Here are key ones to be cautious about:
Supplements that may reduce treatment effectiveness:
- St. John's wort - can make chemotherapy drugs less effective
- Antioxidants - may protect cancer cells from dying during treatment
- Green tea supplements - can interfere with certain lymphoma medications
Supplements that affect blood clotting:
If you have low platelets, bleeding issues, or are having surgery, avoid:
- Vitamin E
- Garlic supplements
- Feverfew
- Ginkgo biloba
- Omega-3 fatty acids
Other concerns:
- Laetrile - doesn't help kill cancer and can cause cyanide poisoning
- High-dose vitamins - can lead to unsafe levels, especially if nutrients are already in your food
- Probiotics during stem cell transplant - may increase infection risk
Always talk with your doctor before starting any supplement, even if it's natural or sold over-the-counter. Some can have serious interactions with your treatment or mask important symptoms like fever.
