Fish oil supplements 'stop chemotherapy from working'
PATIENTS undergoing treatment for cancer could be harming their chances of survival by using fish oil supplements, experts warned.
Dutch researchers say they have discovered that fatty acids in fish oil capsules reduce the effectiveness of chemotherapy, making cancer cells insensitive.
The study, by the University Medical Centre at Utrecht, in the Netherlands, found that stem cells in patients' blood produced the same fatty acids that desensitised tumours to chemotherapy.
The scientists are advising cancer patients against taking fish oil during chemotherapy,
Professor Emile Voest, a medical oncologist at UMC, said: "We currently recommend that these products should not be used while people are undergoing chemotherapy."
