Due to our modern lifestyle, we have become increasingly exposed to chemically reactive free radical molecules on a daily basis. Although some free radicals naturally occur and are needed for normal physiological balance, levels greater than what our body can control may lead to oxidative damage to cells, accelerated ageing, and disease.[1] Pollution, radiation, heavy metals, pesticides, smoking, infection, and stress, are some widely accepted sources of the free radical burden that often tip our delicate balance.[1]  

The body has antioxidant systems in place which have been shown to help protect the life of the cell by safely reducing free radicals,  and may help reduce inflammation and many age-related chronic diseases, such as cardiovascular disease, neurodegeneration, diabetes, and poor immunity.[1,2] 

Several important nutrients supporting the demand on these systems with their antioxidant activity, may lower your risk factors, and increase vital protection when included  as part of your patients' health management plan.[1-4] When prescribed correctly, resveratrol, alpha-lipoic acid, unbiquinol (reduced form of coenzyme Q 10), selenium, beta carotene, vitamins C and E, and the mineral zinc, are all compelling antioxidants which can give added cellular protection, reduce the effects of free radicals, and help maintain health and wellness.[1-4]
