Introduction
The inclusion of many natural dietary supplements in every
recipe is a major selling point for Arden Grange.
Benefits of the
Arden Grange range:
SUPERIOR DIGESTIBILITY
EXCELLENT PALATABILITY
HIGH QUALITY INGREDIENTS
The inclusion of these natural
supplements is another key area
in which Arden Grange excel,
making our diets truly SuperPremium.
Antioxidants
A holistic approach
The benefits of dietary antioxidants are becoming much more
widely recognised in the human health context.
As often happens, advances are made first
in human medicine and nutrition, and
these may then be proven in other species.
This presentation shows the different types
of antioxidant, their role and how those
included within the Arden Grange range
may have positive effects on the health and
well-being of our canine and feline
companions.
Antioxidants
Health and Well-being
As with ALL the dietary supplements used in the Arden
Grange range, the antioxidants included are:
•SAFE
•NATURAL
•EXCELLENT QUALITY
•BIOAVAILABLE (easily utilised)
•PRESENT AT EFFECTIVE LEVELS
Arden Grange provides optimal nutrition at affordable prices.
Antioxidants
Protecting the body
Antioxidants are substances which PROTECT the cells of the
body from unstable molecules known as FREE RADICALS.
Antioxidants interact
with and stabilise
these free radicals
and thus prevent
some of the damage
they might cause if
allowed to
accumulate.
Antioxidants
Oxidative stress
Antioxidant enzymes
occur naturally in the
body, but… low levels
or inhibition of these
enzymes can affect
the body’s ability to
detoxify and to repair
cell / tissue damage.
This results in OXIDATIVE STRESS which in both humans and animals is
associated with ill health.
This is why both we and our pets naturally possess complex antioxidant
systems to protect our cells.
Antioxidants
Natural antioxidants
There are lots of naturally occurring substances with antioxidant
properties. These include:
• VITAMINS (E, C & beta-carotene)
• MINERALS (selenium, zinc, copper and manganese)
• ENZYMES
Some of these antioxidants
work alone (e.g. zinc and
copper),
whilst others form part of
the body’s antioxidant
systems.
Antioxidants
Risks to the body
The body is constantly under attack from free radicals, and
the following factors may all contribute to excessive levels:
• ENVIRONMENTAL POLLUTANTS
• RADIATION
• EXCESSIVE SUN
• PHYSICAL STRESS
• PSYCHOLOGICAL STRESS / ANXIETY
• AGEING
• POOR NUTRITION
Antioxidants
Limiting the risks
There is little that can be done to limit environmental risks,
and we know we cannot reverse the ageing process!
However…Poor nutrition is something that every cat and dog
owner can avoid.
Given the considerable number of
potential causes of free radicals, and
the fact that the production of
naturally occurring antioxidant
enzymes may well be lower than a
cat or dog’s requirements, additional
antioxidant protection by means of
DIET is the sensible solution to the
free radical problem.

SENIORS
Antioxidant supplementation improves the older dog’s
antioxidant defence mechanism.
Zicker (2001)
Landmark discrimination in aged dogs is improved by
feeding an antioxidant enriched diet.
Milgram N W, Estrada J, Ikeda-Douglas C et al (2000)
Antioxidants
Targets
WORKING DOGS
High performance dogs require higher levels of
vitamin C (an antioxidant vitamin) due to increased
demands resultant from oxidative stress
Baskin et al (2000)
Piercy et al (2000)
Antioxidants
Targets
• PREGNANT & LACTATING BITCHES / QUEENS
• PUPPIES & KITTENS
• DOGS & CATS RECOVERING FROM SURGERY OR ILLNESS
• OVERWEIGHT OR UNDERWEIGHT DOGS & CATS
• CATS & DOGS SUFFERING FROM STRESS
A wide variety of
circumstances can affect the
pet’s need for
antioxidant protection…
For this reason, you’ll find
dietary antioxidants in
EVERY Arden Grange recipe
from our Weaning Puppy /
Kitten food through to Senior.
Antioxidants
Dietary antioxidants – vitamins
• Vitamin E – scavenger that converts free
radicals to stable compounds; protects cell
membranes; important for detoxifying
processes in the liver. It cannot be synthesised
by the dog or cat’s body and is therefore the
most important nutritional antioxidant
supplement.
• Vitamin C – regenerates vitamin E; reduces free
radicals in cells; thought to destroy free radicals
involved in carcinogen (cancer causing agents)
metabolism.
• Beta-carotene – direct scavenger of free radicals
and the most powerful of antioxidant nutrients.
• Folic acid (Vitamin B9) – important in red and
white cell formation and has antioxidant
properties.

Dietary antioxidants – minerals
• Selenium – closely interacts with vitamin E (its
antioxidant properties are related to this
interaction); active involvement in glutathione
metabolism (one of the body’s antioxidant
enzymes).
• Zinc, Copper & Manganese – these work
together in the production of the body’s most
important antioxidant enzyme, superoxide
dismutase.

Dietary antioxidants – taurine
• Taurine – an essential amino acid for
cats and is necessary for proper bile
formation, reproduction, healthy vision and
heart function. It is also beneficial to dogs
in respect of cardiac health. It is lesser
known for its antioxidant properties, and
it helps to protect the cell membranes
from damage.
Taurine is naturally present in the meat,
fish, yeast and eggs used in the Arden
Grange recipes, but it is added to the
feline range and to the Performance
canine food to provide a boosted level.
Antioxidants
Dietary antioxidants – plant extracts
• Cranberry Extract – primarily included
for its benefits to urinary tract health,
but is also an abundant source of plant
pigments with powerful natural
antioxidant properties.
• Yucca Extract – may help to reduce
faecal and body odour; it contains
several physiological active
phytochemicals and is a rich source of
polyphenolics which are free radical
scavengers (and may also aid in
suppressing inflammatory responses).

Dietary antioxidants – plant extracts
• Methylsulfonylmethane (MSM) – an all
natural, ultra-pure form of organic
sulphur derived from pine bark. Its
beneficial properties include the relief of
pain and inflammation. It may also
improve mental alertness and relieve
stress. Studies suggest that it may also
have antioxidant properties (although
this is still to be proven).

Dietary antioxidants – special plant extracts in
Arden Grange Performance
Quercitin –
Plant-based chemical called a flavonoid.
Powerful antioxidant properties.
Thought to also be an anti-histamine.
May also be anti-inflammatory.
Green tea extract –
20x more antioxidant-active than vitamin C!
High levels of polyphenols.
Both antioxidant and antibiotic properties.
Grape seed extract –
Source of oligomeric proanthocyanadins.
(Water soluble plant pigments called bioflavonoids).
Helps strengthen the blood capillaries.
Extremely powerful antioxidant, and possibly
the only one with the capacity to cross into the brain.
Note: whilst grapes in
a large volume are
toxic to dogs, grape
seed extract has no
harmful side-effects.
Antioxidants
The ultimate defence
Uncontrolled free radicals can wreak all sorts of havoc to:
• Polyunsaturated fats.
• Cell proteins.
• DNA.
The more active the cell, the greater the resultant tissue damage.
A COMBINATION of antioxidants limits cell damage in dogs and
cats. Heaton et al (2001).
Many of the nutrients with antioxidant properties work in synergy (to
each other’s mutual benefit).
Antioxidants in food are not interchangeable and many differ in
both their site of action and their mechanism.
This is why Arden Grange include lots of different antioxidants –
A POWERFUL SYNERGISTIC ANTIOXIDANT COMPLEX!
Antioxidants
Cancer prevention
Over time, free radical damage
may become irreversible and lead
to disease including cancer.
Antioxidants are often described
as “mopping up” free radicals.
There are a considerable
number of studies indicating
that antioxidants may slow or
possibly prevent the
development of
cancer.

Antioxidants as pet food preservatives
SYNTHETIC ANTIOXIDANTS:
• Used to prevent rubber from perishing.
• Used in petrol as a stabiliser.
• Used as food additives (NOT by Arden Grange).
COMMON EXAMPLES:
• Propyl gallate (PG, E310).
• Tertiary butylhydoquinine (TBHQ).
• Butylated hydroxyanisole (BHA, E320).
• Butylated hydroxytoluene (BHT, E321).
• Ethoxyquin.
There has been much concern regarding the
safety of these synthetic antioxidants which are
often added to pet foods and simply listed as
EU approved or EEC permitted preservatives.

SYNTHETIC ANTIOXIDANTS – watch out!
Other manufacturers sometimes add these to
the raw materials before the ingredients are
incorporated into the pet food and do not
include them in the ingredients listing.
NATURAL ANTIOXIDANTS a
ALL Arden Grange recipes are stabilised
naturally in order to prevent the fats and oils
in the diet from oxidising and becoming
rancid. Without a preservative of some kind,
the products would have a very short shelf life
(a matter of days, which would not be viable
for stockists and customers).
The rosemary
extract we use is
deodorised to
remove the
camphor – meaning
it is safe for
epileptic dogs.
ONLY mixed tocopherols (Vitamin E) and rosemary extract are used to
preserve the Arden Grange raw materials and finished products.
Antioxidants
Summary
Oxidative stress is a proven
causative factor of many diseases
of domestic animals.
Research gives evidence that
antioxidants do have significant
health benefits to our pets.
Recent studies have demonstrated
that antioxidants are beneficial in
cases of:
inflammatory bowel disease
(Khoo C et al 2007)
Boosting immunity
(Park J S et al 2007).
Antioxidants
Summary
Caution
As with many nutritional
supplements, too much of a good
thing can be just as detrimental
as not enough.
Laviano (2007)
Feeding a super-premium quality
food such as Arden Grange which
contains a carefully formulated
and balanced selection of dietary
antioxidants is the best way to
ensure that the levels your dog or
cat ingests are appropriate, safe
and bioavailable.
Antioxidants
Summary
Good news for dog and cat owners!
Red wine and dark chocolate are fantastic sources of
antioxidants.
Don’t forget though that both alcohol and chocolate are
poisonous to our pets, so should only be enjoyed (in moderation)
by us!
Antioxidants
Important Note
As a responsible and ethical company, Arden Grange fully
appreciate the caution that must be taken when discussing the
potential benefits of nutritional supplements. It is against the law
to make medical claims.
Whilst supplements such as the antioxidants included in the
Arden Grange range are safe and natural, and may be beneficial
to some of the cats and dogs fed on Arden Grange, we must
highlight that their inclusion is not a substitute for veterinary
intervention in the case of a sick animal.
THE END
Thank you
All of the healthy, happy cats and dogs
featured in this presentation are fed and thrive
on Arden Grange!
