Antioxidant Support
Free radicals are a natural consequence of oxidation – that vital process that allows our body
to function normally. Free radicals actually play an important role in a number of biological processes, some of
which are necessary for life, such as intracellular killing of bacteria by neutrophil granulocytes. They have also
been implicated in certain cell signaling processes. The two most important oxygen-centered free radicals are
superoxide and hydroxyl radical. They are derived from molecular oxygen under reducing conditions, such as when a
person breathes.
However, because of their high reactivity, free radicals often participate in unwanted side
reactions resulting in cell damage. Many forms of cancer are thought to be the result of reactions between free
radicals and DNA, resulting in mutations that can adversely affect the cell cycle and potentially lead to
malignancy. Scientists have also pointed to free radicals as the cause of some of the symptoms of aging, such as
atherosclerosis, alcohol-induced liver damage, alpha 1-antitrypsin in the lung, and even emphysema.
Now, don’t get this wrong. Free radicals are still necessary for life, but in order to prevent
yourself from developing these diseases, you need to take action in keeping free radicals at a minimum. Fortunately
for us, the body has a number of mechanisms to minimize free radical induced damage and to repair the damage which
does occur. Enzymes superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase, these are
only a few of the substances found in the body that can help repair cell damage.
But that’s only as far as repair is concerned. What about controlling free radicals in the form
of prevention? Now, this is where antioxidant support comes in. Antioxidant support plays a key role in the defense
mechanisms of the body. The most common antioxidant supports are in the form of vitamins, specifically vitamin A,
vitamin C, and vitamin E. In addition, there is good evidence that bilirubin and uric acid can act as antioxidant
support to help neutralize certain free radicals.
Antioxidant support can be found in almost everything that we eat. More particularly, fresh
fruits and vegetables are the richest sources of antioxidant support available. For instance, the antioxidant
support Retinol or Vitamin A (or beta-carotene) are found in dark green, yellow, and orange vegetables and fruits.
In fact, it is the antioxidant support found in these fruits that protect them from solar radiation damage. Another
antioxidant support, ascorbic acid or Vitamin C is a water soluble compound that is found in citrus fruits, green
peppers, broccoli, green leafy vegetables, strawberries, raw cabbage, and tomatoes.
