Do not take antioxidant dietary supplements during treatment, unless you clear it with your oncologist first. Examples of antioxidants include beta-carotene, lycopene, co-enzyme Q10, quercetin, resveratrol, selenium, glutathione and vitamins A, C and E.
Taking a daily multivitamin with modest amounts of these nutrients is fine. Larger megadoses may interfere with the efficacy of some cancer treatments.
It is safe and healthy to eat antioxidant-rich foods and beverages, such as vegetables, fruit, nuts, tea, whole grains and beans, during and after treatment.
However, to avoid negative interactions with cancer treatment, do not use high-dose antioxidant dietary supplements during mesothelioma treatment.
