Antioxidants needed by exercising populations: Nutritionist - Nutra USA,
5/14/09 - "Commenting on the design of the study, Dr
Childs said it was unclear if the subjects encountered the same absolute level
of muscle fatigue during exercise in the supplement and control conditions and
hence stimulus for antioxidant up-regulation. “Because of this, the reported
‘prevention of the ‘health promoting effects of antioxidants’ may be nothing
more than an experimental artefact,” ... In addition, Dr Childs said that
comments by the authors that antioxidants may block many of the beneficial
effects of exercise were a “gross over extrapolation of the experimental
findings on two levels”"
-
Vitamin-exercise study questioned - Nutra USA, 5/12/09 -
"The authors noted that biopsies for the ‘early’
time-point were only obtained from five people in the vitamin group, and four in
the placebo group. “Yet the authors conclude a “strong induction of PGCl-alpha,
PGCl-beta, and PPAR-gamma expression in skeletal muscle following 4 weeks of
exercise training in previously untrained, antioxidant naïve individuals” and
“markedly reduced exercise-related induction” in those taking antioxidants,
based on these limited number of biopsies,” ... “Would it not have made more
sense to appropriately increase the intensity and duration of exercise slowly
and then see if the subject’s bodies didn’t accommodate handling of ROS without
a significant change in induction of these markers?” ... The study reflects a
‘transient’ increase in ROS during ‘limited periods of physical exercise only’,
noted Dr Schauss, “whereas the bulk of the literature, including that in
non-primate models have not observed these concerns obtained in models of
‘continuous exposure to increased levels of ROS’” ... the authors presented no
evidence of adverse effects by any of the individuals from vitamin C and E
supplementation"

Antioxidant Found In Berries, Other Foods Prevents UV Skin Damage That Leads To
Wrinkles - Science Daily, 4/21/09 - "Using a topical
application of the antioxidant ellagic acid, researchers at Hallym University in
the Republic of Korea markedly prevented collagen destruction and inflammatory
response – major causes of wrinkles -- in both human skin cells and the
sensitive skin of hairless mice following continuing exposure to UV-B, the sun's
skin-damaging ultraviolet radioactive rays ... Ellagic acid is an antioxidant
found in numerous fruits, vegetables and nuts, especially raspberries,
strawberries, cranberries and pomegranates ... the results demonstrate that
ellagic acid works to prevent wrinkle formation and photo-aging caused by UV
destruction of collagen and inflammatory response"

Reductions In Cancer And Overall Mortality Persist 10 Years After Vitamin And
Mineral Supplementation - Science Daily, 4/2/09 - "Individuals
who took a dietary supplement called "factor D", which included selenium,
vitamin E, and beta-carotene, continued to have lower gastric cancer and overall
mortality 10 years after supplementation ceased compared with individuals who
did not take the supplements ... Individuals who took factor D continued to show
benefits, with a 5% reduction in overall mortality (from a cumulative mortality
of 33.62% of participants not taking factor D to 32.19% of participants taking
factor D) and an 11% reduction in gastric cancer mortality (from a cumulative
gastric cancer mortality of 4.28% in the no-factor D group to 3.84% in the
factor D group)"

Antioxidants May Fight Fat - WebMD, 11/2/07 - "Those
antioxidants didn't kill fat cells or slash the number of fat cells in the test
tubes. Instead, they made fat cells cut their production of triglycerides, which
are a heart hazard. The antioxidants did that by curbing an enzyme needed to
make triglycerides ... That particular enzyme was most effectively reduced by
the phenolic acid o-coumaric acid and the flavonoid rutin"

Antioxidant To Retard Wrinkles Discovered - Science Daily, 8/30/07 -
"Antioxidants operate against free radicals which cause
a breakdown of many tissues in the body, including the skin. When found in small
quantities in the body, free radicals are not harmful and are even involved in
various physical processes. When there is an excess of free radicals, however,
as occurs during normal aging or as a result of excessive exposure to
ultra-violet radiation from the sun, the result, among other things, is a
breakdown of the collagen and elastin fibers in the skin. When this happens,
there is a loss of skin elasticity and the formation of wrinkles ... A problem
with many of the commercial antioxidants found today in the market that are said
to retard the aging process is that they oxidize quickly and therefore their
efficiency declines with time"

Use of Some Antioxidant Supplements May Increase Mortality Risk - Doctor's
Guide, 2/28/07 - "In an analysis that
pooled all low-bias risk and high bias risk trials, there was no significant
association between antioxidant use and mortality. In 47 low-bias trials
involving 180,938 participants, the antioxidant supplements were associated with
a 5% increased risk of mortality. Among low-bias trials, use of beta carotene,
vitamin A, and vitamin E was associated with 7%, 16% and 4%, respectively,
increased risk of mortality, whereas there was no increased mortality risk
associated with vitamin C or selenium use" - [Abstract]
- Note: Beta-carotene is just one of over 600 carotenoids and taking just
one may cause a deficiency of the others. I had a couple articles on that
but the links went dead. Same with taking just the alpha tocopherol form
(most common form) of vitamin E. I've been saying for years that taking
alpha tocopherol or beta-carotene alone causes more harm than good. I get
my beta-carotene from
Dunaliella Salina Algae
(Body Wise Brand), which
contains the broad spectrum and vitamin E from
Jarrow FamilE (contains all eight members of the vitamin E family) at iHerb

increase free radical formation. Researchers say damage from free radicals
leads to skin wrinkling, redness, brown “age spots” and increased risk of
skin cancer. Antioxidants neutralize free radicals and even repair some of
the damage done ... For now, scientists aren’t sure whether antioxidants are
best applied in lotions or creams or consumed in foods or supplements"
- What do you

lutein, zeaxanthin, lycopene, etc. As for vitamin E, most studies use
synthetic alpha-tocopherol. I recommend using natural vitamin E supplements
that provide all four tocopherols and all four tocotrienols"

- MEDLINE Abstracts: Antioxidants and the Aging Brain
- Medscape, 9/27/02 - "Combinations
of antioxidants might be of even greater potential benefit for AD,
especially if the agents worked in different cellular compartments or had
complementary activity (e.g. vitamins E, C and
ubiquinone). Naturally-occurring compounds with antioxidant capacity are
available and widely marketed (e.g. vitamin C,
ubiquinone,
lipoic acid,
beta-carotene, creatine,
melatonin, curcumin) and synthetic
compounds are under development by industry" - Again, a broad

Comparison of Antioxidant Potency of Commonly Consumed Polyphenol-Rich
Beverages in the United States - J Agric Food Chem. 2008 Jan 26 -
"pomegranate juice (PJ) ... PJ had the greatest
antioxidant potency composite index among the beverages tested and was at
least 20% greater than any of the other beverages tested. Antioxidant
potency, ability to inhibit LDL oxidation, and total polyphenol content were
consistent in classifying the antioxidant capacity of the polyphenol-rich
beverages in the following order: PJ > red wine > Concord grape juice >
blueberry juice > black cherry juice, açaí juice, cranberry juice > orange
juice, iced tea beverages, apple juice. Although in vitro antioxidant
potency does not prove in vivo biological activity, there is also consistent
clinical evidence of antioxidant potency for the most potent beverages
including both PJ and red wine" - See
