What are free radicals? Why are they damaging to the human body? - by Newman Doo
Our body tissues are made up of cells.
Each cell is composed of many different types of molecules.
• Molecules consist of one or more atoms of one or more elements joined by chemical bonds.
An atom
• The number of protons (positively charged particles) in the atom nucleus determines the number of electrons (negatively charged particles) surrounding the atom.
Electrons
Electrons surround, or
"orbit" an atom in one or
more shells.
How is Free Radical Formed?
• When a electron is lost from an atom, an unstable free radical is formed.
Chain reaction of radical formation.
When the molecule loses
its electron, it becomes a
free radical, beginning a
chain reaction. Once the
process is started, it can
cascade.
How a cell is damaged.
Finally a living cell is
disrupted.
Causes of free radical formation-oxidative stress
Environmental factors
such as pollution,
radiation, cigarette
smoke and herbicides
also spawn free radicals.
Many drugs cause free radicals
• Drugs
adriamycin
bleomycin
mitomycin C
nitrofurantoin
chlorpromazine
Stress
The pressures common
in industrial societies can
trigger the body's stress
response. In turn, the
stress response creates
free radicals in
abundance.
Viruses and bacteria
• Sometimes the body immune system cells purposefully create free radicals to neutralize viruses and bacteria.
Sports
Oxygen, although
essential to life, is the
source of the potentially
damaging free radicals.
Endurance exercise can
increase oxygen
utilization from 10 to 20
times over the resting
state.
Damages of free radicals
Free radicals may lead to
health problems such as• skin aging• heart disease• cataracts• cancer• arthritis• diabetes
Skin aging
Free radical damage
causes wrinkles by
breaking down skin
collagen, elastin and
other proteins in the skin.
Free radicals and heart disease
• Free radicals cause damage to individual cells within the arteries.
Oxidized LDL(low density lipoprotein)
LDL itself is harmless.
Only when oxidized--
that is, does LDL
cause the arterial
hardening and clogging
that lay the groundwork
for heart attack and
stroke.
Free radicals and cancer
Free radicals damage
DNA causing tumor
initiation, promotion &
conversion .
Cataract
• A cataract is a clouding of the lens in the eye that affects vision.
• Free radicals is a major cause of cataract formation.
Arthritis is believed to be a disease stemming from an attack of ourown T-Cells on our joint membranes and fluids. The T-cells makedeadly free radicals to use in attacking enemies like bacteria, viruses,and cancer cells. But when the T-cells make mistakes and attack ourown cells, they use the damaging free radicals on us. In arthritis, thechemically reactive free radicals damage the joint membranes and lubricants, resulting in the pain and limited mobility of arthritis.
Arthritis
Diabetes
Free radicals damage
insulin-producing “beta
cells” in the pancreas
causing diabetes.
How Antioxidants May Prevent Against Free Radical Damage
An antioxidant can neutralize a free radical by
donating one of its electrons without
jeopardizing its own chemical stability.
It is a free radical scavenger and
prevents cell damage.
An electron circuit to prevent oxidation of cell membrane byantioxidants OPC, Vitamin C & E.
Isotonix OPC-3• Red wine extract, pine
bark, isoflavonoids, bilberry and grape seed extract are the strongest known antioxidants.
• 20 – 50 times more effective than vitamin C and vitamin E respectively, at neutralizing oxygen radicals
•Improves skin smoothness & elasticity•Strengthens capillaries, arteries and veins•Improves circulation and enhances cell vitality•Reduces capillary fragility and improves resistance to bruising and strokes•Reduces the risks of phlebitis(a clot in the vein)•Reduces edema and selling in the legs•Reduces varicose veins•Reduces restless legs syndrome•Improves visual acuity•Helps improve sluggish memory•Reduces the effects of stress•Improves joint flexibility and reduces inflammation caused by arthritis and sports injuries
Administration of OPC-3 Dosage
• Take on an empty stomach and wait 10-15 minutes before eating or drinking.
• Loading dose – For the 1st 7 days, take 1 white capful per every 75 pounds of body weight. OPC-3 is non-toxic.
• Those with physical challenges, continue the loading dose for up to 30 days before shifting to a maintenance dose.
• For preventative health measures, a maintenance dose is considered to be 1-2 capfuls of OPC-3.
• I white capful contains 75 mg of active OPC and 50 mg of bioflavonoids.
Isotonix OPC-3 the best deliverable system for absorption
