everyone has heard of antioxidants and the free radicals that they
neutralize. Vitamins A, C, E, and other antioxidant vitamins are
now household words. We tend to think of free radicals as the “bad
guys” and antioxidants as “good guys”. The flame of our life, however,
is oxidation—the controlled burning of fuel to produce energy. Free
radicals are natural by-products of this process, and are also generated
and used by our immune cells in carrying out their ordinary tasks
to help maintain a healthy body.
Antioxidants representthe “insulation” that allows us to safely
handle this “fire”, thus protecting our cells while the fire “warms
our house”. Processes that increase production of free radicals are
collectively referred to as “oxidative stress”.
Cellular protection is determined by the balance between oxidative
stress and antioxidant intake, along with the reserves maintained
in your body.
There is a baseline level of oxidative stress simply
from using oxygen to burn fuel for the production of energy, which
is necessary to stay alive and be active. Many factors of modern
life, however, have increased oxidative stress dramatically: smoking
(both active and passive), alcohol, non-prescription and prescription
drugs, environmental pollution, high altitude jet travel, and exposure
to other chemicals. Cigarette smoke, for example, contains thousands
of different chemicals, and a single puff of cigarette smoke contains
trillions of free radicals. Cigarette smoke literally burns away
antioxidant nutrients. Cigarette tars are long-lived free radical
Antioxidant nutrients function most effectively
as a network. They donate electrons to the highly reactive unstable
free radicals in order to “quench” them,
making them chemically stable again, thus terminating their chain
reactions. Molecules without antioxidant properties may perpetuate
these chain reactions thatattack cell membranes and DNA, as well
as other cellular structures. An antioxidant, in the process of quenching
a free radical by donating its electron(s), becomes oxidized itself,
and must be regenerated into its “reduced” (the opposite of oxidized)
form in order to become a functional antioxidant molecule again.
Maintaining a broad spectrum of various types of antioxidant nutrients,
rather than larger amounts of just one single antioxidant, is essential
to promoting your good health.
When a single antioxidant nutrient is present in larger amounts,
there is a chance it will function as an oxidant, in the absence
of partners to recycle it back to its antioxidant state. In this
situation, the process of stabilizing a free radical is incomplete
and the antioxidant becomes a free radical itself, by perpetuating,
rather than terminating, the chain reaction. This principle may explain
the paradoxical effect seen in a study of smokers in Finland who
were given large amounts of synthetic beta-carotene to see if it
would protect them from lung cancer; the result was an increase by
nearly 20% of lung cancer cases in the beta-carotene supplemented
In another example, laboratory research has shown that vitamin E
added to cholesterol in the absence of Co-Q-10 (another important
fat-soluble antioxidant) will actually promote oxidation of the cholesterol,
whereas, if Co-Q-10 is also present, the cholesterol is protected
from oxidation. Co-Q-10 is contained in every living cell (hence
its scientific name ubiquinone, because of its ubiquitous nature)
and is necessary for human life to exist.
The above examples illustrate why it is important to supplement
with a wide variety of antioxidant nutrients, rather than just a
Because Co-Q-10 is quite expensive, it is usually provided as a
single product supplement, combined with a source of fat (such as
vitamin E or lecithin), to enhance its absorption, or formulated
in lower amounts when combined in a multiple antioxidant supplement.
Many cardiologists and researchers believe that minimizing oxidized
cholesterol, in addition to other important nutritionalfactors, is
essential to maintaining healthy arteries and promoting already healthy
Because antioxidants function in your body
as an interacting network, it makes sense to eat a well-balanced
diet, rich in a wide variety of fruits and vegetables that contain
many different antioxidant compounds.
You should be sure to include a wide range of antioxidants, some
of which work in the water-soluble areas of the body (like vitamin
C) and others that work in the fat-soluble areas of the body (like
vitamins A, E and Co-Q-10).
Depending upon your diet and lifestyle, you may not always maintain
adequate levels of the broad spectrum of antioxidants needed for
optimum function of the interacting antioxidant network in your body.
Therefore, to guarantee that your body retains the proper antioxidant
reserves, you may want to take these antioxidants on a daily basis,
reinforcing your diet with nutritional supplements that contain higher
levels of a wide range of antioxidants.
Xtra Antioxidants contains many different potent antioxidant nutrients
and extracts from certain plants known to be particularly rich in
antioxidant compounds, such as polyphenols and flavonoids.
Included in this formula are high-quality,concentrated extracts
from the following plant sources:
- Turmeric (95% curcuminoids)
- Milk-thistle seed (80% Silymarin)
- Noni fruit
- Bilberry fruit
- Ginkgo leaves
- Citrus fruit
- Green tea leaves
Additional powerful antioxidant compounds that are
also plant-derived such as hesperidin, quercetin, lycopene, lutein,
and alpha-lipoic acid are also included.
Several of these compounds appear to have unique properties that
make them particularly supportive and protective against oxidative
stress inspecific organs, for example:Ginkgo biloba and alpha-lipoic
acid for the brain; lycopene for the prostate; lutein and bilberry
for the eyes; and milk thistle and alpha-lipoic acid for the liver.
Glutathione, a peptide linkage of three amino acids (L-glutamic
acid, L-cysteine, and L-glycine), is part of the fundamental antioxidant
system present in every cell of virtually all animals.
Lutein promotes healthy immune function. There are already over
250 scientific articles referring to lutein's potential in promoting
the growth of healthy cells. Animal studies have shown that lutein
supports the growth of natural white blood cells in mice, among other
health promoting factors.
Lycopene is a natural carotenoid that has potent antioxidant activities.
It is responsible for the bright red color of tomatoes, red grapefruit,
guava, and watermelon, which are the richest natural sources of this
Lycopene is better absorbed from cooked tomato products than from
Research has also shown that lycopene supplements actually raise
tissue stores of this carotenoid better than tomato juice.
Alpha-lipoic acid (ALA) is equally soluble in lipids (fats and oils)
and water, and so can move easily throughout both the lipid and water
compartments of the body, enter the brain easily, and is especially
effective at quenching free radicals within cell membranes. It is
well absorbed when taken orally andregenerates most of the other
antioxidants including vitamins C and E, as well as co-enzyme Q-10.
It is the most effective nutritional antioxidant in bolstering cellular
and tissue levels of glutathione, which is a master physiological
antioxidant that orchestrates the biological interaction of many
Naturally this formula would not be complete
without the “standard” antioxidant
vitamins A, C, and E, as well as a natural carotenoid complex, which
contains many carotene compounds derived from colored vegetables,
including beta and alpha carotenes; cryptoxanthin, and zeaxanthin.
In addition to their other important nutritional functions, folic
acid (a B vitamin) and selenium (a mineral) serve as critical antioxidants.
Selenium is a trace mineral that activates an antioxidant enzyme
called glutathione peroxidase, which help protect the body from free
radical attack. Selenium also enhances the antioxidant effect of
vitamin E. Additionally it is needed to activate thyroid hormones.
Though many nutrition experts recommend at least 200 mcg daily, the
Daily Value (DV) of selenium isonly 70 mcg. Many people don't even
get 70 mcg of this critical nutrient unless their diet includes selenium-containing
supplements or selenium-rich foods, such as yeast, whole grains,
seafood, garlic, onion, Brazil nuts, or broccoli. Even these foods
vary widely in their selenium content depending on the selenium content
of the soil in which they were grown.Brazil nuts are the richest
known source of selenium; one ounce contains approximately 200 mcg.
Selenium is also essential for healthy immune function.
Since the discovery that the central human retina (called the macula)
concentrates two particular carotenoids, known as lutein and zeaxanthin,
much research attention has been focused on these particular members
of the carotene family. These carotenoids are found in highest concentrations
in kale, spinach, collard greens, romaine lettuce, leeks, peas, and
People who eat a lot of spinach and kale, which are rich sources
of lutein and zeaxanthin, have been reported to help maintain healthy
youthful vision. Lutein and zeaxanthin, like the other carotenoids,
are potent antioxidants. Lutein is also the only carotenoid found
in the lens of the eye as well as in the macula of the retina which
contains the highest concentration of light-sensitive nerve receptors.
Carotenoids are brightly colored compounds that provide red, orange,
and yellow coloring to many fruits and vegetables. For decades, they
were dismissed as mere food colorants, but today they are known to
be vitally important to health. Virtually all of them have been found
to be potent antioxidants, which protect various body tissues from
free radical attack. Carotenoids found in foods and thought to be
of greatest importance to health include alpha and beta carotene,
lutein, lycopene, cryptoxanthin, and zeaxanthin. These are all found
in natural carotenoid complexes, extracted from carotene rich plant
Therefore, carotenoid complexes have been included in Xtra Antioxidants
to provide you with one of the most complete broad-spectrum antioxidant
supplements on the market today.
A healthful diet, pure drinking water, regular
exercise, meditation, and/or other stress management techniques,
plus Xtra Antioxidants are enormously useful tools for the pursuit
and maintenance of wellness. †
