A Guide to Antioxidants

The following article is aimed at informing you of what antioxidants are (and by extension what free radicals are) and what you can do to increase your supply of these vital health promoters.

We hope that you enjoy this piece. If we can be of any further assistance please don’t hesitate to contact us.

Antioxidants and Your Health


What Are Antioxidants?  


Antioxidants are vital to our general health, without them quite simply we would cease to function!    


Essentially they work in the body mainly as free radical scavengers: they mop up and neutralise these damaging substances.


The main antioxidants are:









Vitamin E

Vitamin A: carotenes

B Vitamins


Vitamin C

What Are Free Radicals?

Free radicals are atoms or molecules that are capable of independent existence and are highly reactive. They are naturally occurring, formed in the body as part of normal function and also ingested/consumed quite normally.


Free radicals are so reactive due to the presence of unpaired electron(s) which makes them unstable. In nature there is a quest for stability and free radicals are no exception to this rule, in order to achieve stability steal an electron from a surrounding compound or molecule. This would be fine and well but a natural consequence is that a new free radical is formed in its place thereby a chain reaction continues.


Antioxidants – Free Radical Quenchers

Antioxidants work to protect against the damaging action of free radicals because they give up their own electrons to free radicals. When a free radical gains electron(s) from an antioxidant it no longer attacks cells and tissues of the body to achieve stability and the chain reaction of oxidation is broken.


Are antioxidants at all dangerous?


After donating an electron an antioxidant becomes a free radical by definition (i.e. it has lost its stability). However in general, antioxidants in this state are not harmful because they have the ability to accommodate the change in electrons without becoming reactive.


So is it advisable to take several antioxidants in conjunction?


The key antioxidants (such as vitamin C, E and Co Q10) work synergistically and when combined can enhance the activity of each. These antioxidants help to effectively recycle each other after they have neutralised free radicals.


Do Free Radicals Have Beneficial Effects?


Free radicalsIndeed. Just like antioxidants, without free radicals we would cease to function!


Free radicals reactions in the body are a necessary and normal consequence of form and function, for example:


Immune System


Phagocytes are immune system’s troops that battle and destroy foreign invaders; they often generate and use free radicals to kill invaders.




The liver uses free radicals to detoxify various chemicals.




The thyroid gland is our metabolism controller and it’s cells produce free radicals in order to synthesise and activate the crucial metabolism hormone thyroxin.


Cardiovascular Health


Nitric oxide is a potent free radical and is a normal blood circulation (it has a vasodilatory and constrictive effect on blood vessels).


Consequences of Free Radical Damage

In their quest to achieve balance free radicals damage cells and tissues and cause instability, such as:


Energy balance


The powerhouse of our cells, the mitochondria produce free radicals which damage it’s inner and outer membranes. This can lead to poor transfer of energy from the mitochondria; conditions such as chronic fatigue syndrome have been linked to damages mitochondrial membranes.

Damage to mitochondrial DNA is linked to early ageing.


Immune System


Free radicals can damage cells of the immune system leading to the emergence of dysfunctional white blood cells that are unable to perform their tasks properly thus weakening the immune system.


Cell communication


Cell membranes are made up of lipids (fats) which are vulnerable to attack from free radicals leading to lipid degeneration. Since the lipid membrane of the cell is home to various gateways and channels, any free damage can have severe consequence.

For example, the cell membrane holds receptors that control the entry of glucose. Glucose is our major fuel, therefore free radical damaged membranes may mean problems with poor energy uptake and lead to problems such as diabetes mellitus.


Free radical damage is important in the development of various

conditions, notably cataracts, cancer and cardiovascular disease.


Sources of Free Radicals


(in the body)



(from outside of the body)


Energy production


Foods that contain damaged oils (e.g. refined cooking oils)


Immune system activity


Chemicals (e.g. smoke, drugs, etc)


Thyroid hormone synthesis


Radiation (e.g., from sun and UV light)









Polyunsaturated fatty acids


Barbecued/ charred food

Who Would Benefit From Antioxidant Supplementation?

Everyone is susceptible to free radical damage, however some people may require additional protection: if free radical load exceeds the body’s ability to cope with it.
  • Individuals who exercise excessively
  • Heavy drinkers
  • Smokers
  • The elderly with degenerative disease
  • Individuals living or working in polluted environments
  • People whose diets are a poor source of fresh fruit and vegetables
  • People whose diets are high in convenience foods
