Molecules consist of one or more atoms of one or more elements joined together by chemical bonds. A typical atom is comprised of a nucleus - neutrons, protons, and electrons. Electrons are those negatively charged particles that orbit the cluster of protons in an atom. When there are eight electrons in an orbit, it means that that particular orbit (or shell as it is called) is full which further means the atom is stable. Supplements of these antioxidant enzymes are also available. Usually they are for oral administration in the form of pills or capsules. However, the absorption of antioxidant enzymes in supplement form is minimal at best. A better way would be to supplement the body with the "building blocks" required in order for our body to manufacture its own SOD, catalase, glutathione peroxidase, and other such antioxidant enzymes. Based on their findings, scientists say that by the time you are 20 years old, most of the cells that make up your body have already used up half of their available cell divisions in their cell lifespan. That means by the time you are 40, your cells may only have 30 per cent of cell divisions left. This is actually the reason behind the physical changes that goes on not only inside but outside the body as you approach your years. These days, when we talk about antioxidants, the first thing that comes to people's minds is "supplements." However, studies on antioxidant supplements are for the most part inconclusive and so far, no one study has come up with the same results during antioxidant supplements tests. No problem though because you can always find antioxidant foods almost anywhere. 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. Hence, this aspect of antioxidant antiaging therapy focuses more on extrinsic aging, which is the aging process compounded by externally caused factors. Hence, diseases such as cardiovascular disease, Parkinson's, Alzheimer's, senility, and cancer are often attributed to the contributing factor of free radicals. The Effects of Antioxidant Juice The only way for the body to defend itself from free radicals is through antioxidants. Unfortunately, human beings are one of the few animal species that do not produce their own antioxidants.
