Antioxidant Enzyme
During normal metabolic functions highly reactive compounds called free radicals are created in the body.
However free radicals may also be introduced from the environment. These compounds are inherently unstable since
they have an odd number of electrons. To make up for their shortage in electrons these free radicals will react
with certain chemicals in the body and in so doing they interfere with the cell’s ability to function normally.
However just as the body naturally produces free radicals it also has a means to defend against its harmful
effects. Antioxidant enzymes are chemical substances found in plants that act on free radicals. Antioxidant enzymes
work in several ways. For one they may reduce the energy of the free radical or give up some of their electrons for
its use thereby causing it to become stable. Antioxidant enzymes may also stop the free radical from forming in the
first place. In addition they may also interrupt an oxidizing chain reaction to minimize the damage caused by free
radicals. In sum the main function of antioxidant enzymes is neutralizing free radicals.
For the past decade countless studies have been devoted to the beneficial effects of antioxidant enzymes. It has
been found that a substantial link exists between free radicals and more than sixty different health conditions
including the aging process cancer and atherosclerosis. By reducing exposure to free radicals and increasing the
intake of antioxidant enzyme rich foods or antioxidant enzyme supplements your body’s potential to reducing the
risk of free radical-related health problems is made more palpable.
The human body produces several types of antioxidant enzymes. The antioxidant enzymes include superoxide
dismutase (SOD) catalase and glutathione peroxidase. These antioxidant enzymes neutralize many types of
disease-causing free radicals ridding the body of their harmful effects.
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. The building block nutrients of
antioxidant enzymes include the minerals manganese zinc and copper for SOD and selenium for glutathione
peroxidase.
In addition to antioxidant enzymes many vitamins and minerals may also have antioxidant properties. These
include vitamins C E A (beta-carotene) and nutrients such as lutein lycopene vitamin B2 coenzyme Q10 and cysteine
(an amino acid). Herbs such as bilberry turmeric (curcumin) grape seed or pine bark extracts and ginkgo can also
provide powerful antioxidant protection for the body.
