Our bodies will always be vulnerable to oxidation and it is something that is beyond our hands to control. During oxidation, certain chemical substances are produced and among them are those that are highly reactive and chemically unstable. These substances are called free radicals. Free radicals can be harmful to the body, especially if there is an excess of them. A natural antioxidant protects the body against free radicals. One of the many functions of natural antioxidants is to work against the formation of cellular damage caused by free radicals. Free radicals are highly reactive chemical substances which are produced whenever our body undergoes the process of oxidation, e. In this article, we will attempt to answer all your questions about antioxidant and free radicals, plus help you understand why it is so important to include rich sources of antioxidant nutrients in your daily diet. A Little Background on Chemical Bonding When talking about antioxidant and free radicals, we can't help but touch a little on biochemistry. This antioxidant dietary supplement works best when taken with Vitamin C as it seems that both vitamins have synergistic effect when taken in combination. Besides vitamins, antioxidant dietary supplements may be in the form of botanicals. Green tea, for example, is a rich source of the flavonoid derivatives (polyphenols) epicatechin (EC), epigallocatechin (EGC), epicatechin gallate (ECG), and epigallocatechin gallate (EGCG). Chain-breaking is also called Stabilization. The other aspect is more on the preventive side. Antioxidant enzymes like superoxide dismutase, catalase, and glutathione peroxidase prevent oxidation by reducing the rate of chain initiation. This time, instead of waiting for the free radicals to make a long chain of free radicals, antioxidants scavenge initiating radicals and destroy them before oxidation is set in motion. But do you understand what they do? If not, then read on. What is antioxidant antiaging therapy? Modern theories of aging are generally looked at in two theoretical ways - the damaged theories and the programmed theories. The damage theories of antiaging primarily look at the damage that our cells incur over time.
