Hi, Brief answer: In my opinion, if taken as directed, there is likely little harm in taking the Antoxid hc multivitamin and mineral supplement. However, the best sources of these same vitamins and minerals is from a balanced diet rich in fruits and vegetables. Detailed answer: Antoxid hc contains many vitamins and minerals that serve as antioxidants to help boost the body immune system, fight inflammation, and prevent damage to organs from oxidizing free radicals. In particular the Antoxid hc contains beta-carotene, a form of vitamin A, which helps with promoting good skin health and vision functions. Note though that supplementation with beta-carotene has not been shown to reduce the risk of heart disease or cancer. Beta-carotene supplementation has been shown to be linked to lung cancer, but the evidence is conflicting, and the increased risk in lung cancer is more so for smokers and individuals exposed to asbestos. Also, too much beta-carotene from supplements can cause yellowing of the skin. I recommend patients to consume dietary sources of beta-carotene because beta-carotene from natural food sources do not harm the body. Foods rich in beta-carotene include carrots (boiled), sweet potatoes, dark leafy greens (eg, kale, spinach, mustard greens), and butternut squash. Please consult with your doctor about all medications you are taking, including supplements. You doctor can also provide you with information on dietary sources for specific vitamins and minerals. Hope I have answered your question. Let me know if I can assist you further. Take care. Regards, Dr. Shapiro, MD
