OXIDATIVE STRESS Oxidative stress, what to do now?
RECOMMENDATIONS 1)Antioxidant-rich diet 2)Additional intake of free-radical scavengers 1)Vitamin C 2)Vitamin E 3)ß-carotene 4)Alpha lipoic acid 5)Coenzyme Q10? Ubiquinol? 6)Selenium – how much? GPX1-gene 3)2 Cups of coffee/day for 7 delay of the breast cancer occurrence? OXIDATIVE STRESS Oxidative stress, what to do now?
