Idebenone - The ultimate anti-aging
by James South MA
Idebenone is a synthetic analogue of one of life's most essential
biochemicals, coenzyme Q10. CoQ10 is an important antioxidant component
of the lipid (fatty) membranes that surround all cells, as well as the lipid
membranes surrounding the various organelles ("little organs"), such as
mitochondria and microsomes, inside cells.
CoQ10 is also an important member of the "Electron Transport Chain" within
mitochondria, which are the "power plants" of the cell. Most of the oxygen we
breathe is used inside the Electron Transport Chain to produce much of the ATP
bioenergy that powers virtually every activity of our cells and bodies. Without
CoQ10, or a good substitute, human life quickly ends, and Idebenone is a "better
CoQ10" that has been extensively researched the past 15 years.
CoQ10's pro-oxidant action
When blood flow is seriously reduced to any part of the body, as in a heart
attack, stroke, trauma, shock, or chronic poor blood circulation- cellular/
mitochondrial oxygen levels quickly drop in the affected region. Yet because
oxygen is seven to eight times more soluble in the lipid zones of cell membrane,
compared to the watery compartments of the cell, there is still sufficient
oxygen remaining in the membranes of cells and organelles, as well as in the
Electron Transport Chain, to auto-oxidize CoQ10.
As the CoQ10 auto-oxidizes, hydrogen peroxide, superoxide and hydroxl free
radicals are rapidly formed in massive numbers. These free radicals quickly
damage cell/ organelle structure and function, as well as rapidly halt ATP
energy generation by the Electron Transport Chain. Brain and spinal cord cells
are especially prone to such damage, and may be irreparably damaged or even
destroyed within minutes.
Why Idebenone is superior to CoQ10
Enter Idebenone to the rescue! Studies have shown that under the same cellular
low oxygen conditions that cause CoQ10 to act as a pro-oxidant producer of
damaging free radicals, Idebenone prevents the free radical dam-age and
maintains relatively normal cell ATP levels. In short, while Idebenone can
effectively substitute for CoQ10's positive and life essential functions, it
doesn't have CoQ10's free radical producing and energy crashing "dark side"
which occurs under hypoxic (low oxygen) conditions. Idebenone's potential
benefits fall into five categories; antiaging, energy enhancement, cognition
enhancement, organ protector and protector against excitatory amino acid
Idebenone - The anti-aging benefits
The mitochondrial power plants produce over 90% of all cellular ATP bioenergy.
They are also generally the richest sites in CoQ10 (or Idebenone). Mitochondrial
DNA (mtDNA) allows mitochondria to reproduce them-selves. While the DNA in a
cell nucleus comes from both our parents, Mitochondrial DNA comes exclusively
from our mother's Mitochondrial DNA.
There are typically two or three copies of Mitochondrial DNA in each
mitochondrion, with average 1000 mitochondria per cell. Because Mitochondrial
DNA exists in the "heart of the fiery furnace" where electron "sparks" are
constantly leaking as ATP is produced in the Electron Transport Chain.
Mitochondrial DNA is far more prone to free radical electron damage than is the
DNA in our cell nuclei that contains the "blueprint" for our entire organism.
At the same time, the repair capacity of Mitochondrial DNA is much less than
that of our cell nucleus DNA. As a consequence, over the course of a lifetime
our Mitochondrial DNA becomes ever more damaged, and the mitochondria produced
therefrom become ever more ineffective at energy generation. Studies comparing
heart tissue from young people with that from elderly people have shown almost
no significant mitochondrial dysfunction in young hearts, with significant,
often severe mitochondrial dysfunction in elderly hearts.
The cells that are most susceptible to mitochondrial energy depletion with
advancing age are the brain, skeletal muscle and heart muscle cells. Idebenone
thus offers a prime anti-aging effect here in several ways. Unlike CoQ10, even
under the low oxygen conditions that may occur periodically over a lifetime,
Idebenone will serve as a powerful mitochondrial free radical quencher,
lessening the ever-increasing Mitochondrial DNA damage that occurs with age.
Idebenone will work even better than CoQ10 within the Electron Transport Chain
to keep energy production high, even under hypoxic conditions. This is
especially critical to brain and heart cells that may be rapidly damaged during
low ATP production episodes that occur due to poor tissue oxygenation.
Idebenone - Energy enhancement
Iron is a "dual edged sword." It is absolutely essential for life, it plays a
central role in ATP generation in the Electron Transport Chain. Yet iron can
also be a powerful initiator of free radical production and cell structural
damage, especially under low oxygen conditions.
This occurs, for example, during stroke, and during the gradual onset of
Parkinson's disease. Studies have shown that Idebenone can tightly couple
oxidation to energy production. This prevents iron ions from wastefully and
toxically, diverting oxygen to producing free radicals inside the mitochondria,
instead of energy.
Studies have shown that Idebenone can almost completely eliminate this,
diverting 10% of cellular oxygen away from toxic iron induced free radical
generation, to beneficial ATP energy production under hypoxic conditions. Mild
cellular hypoxia can occur even from intense exercise, or even from mild
exercise done by out of shape "couch potatoes."
Idebenone - Cognition enhancement
A variety of studies using brain cells, (animal and humans) have shown
Idebenone's ability to enhance brain structure and function. Human and animal
studies have demonstrated that Idebenone can enhance serotonin production, even
under far less than optimal conditions, as e.g. with a very low tryptophan diet,
or in patients with cerebrovascular dementia.
Idebenone has enhanced cholinergic nerve function and consequent learning
ability even under hypoxic conditions, or when an anti-cholinergic drug
(Scopolamine) was administered. Idebenone has increased cellular catecholamine
(dopamine, adrenalin and noradrenanlin) production by enhancing cellular uptake
of the precursor amino-acid tyrosine.
Idebenone enhances long term potentiation in hippocampal nerve cells, a key part
of memory formation and consolidation. Idebenone has restored glucose (brain
fuel) utilization and ATP production in ischemic (poor blood flow) rat-brain.
Idebenone has been shown to enhance general cerebral metabolism, lessen the
damage from strokes, and has been used to treat Alzheimer's and other dementias.
And like the nootropic drug; piracetam, Idebenone has been shown to promote
information transfer across the corpus callosum, the membrane separating the
right and left brain hemispheres. This is turn may promote the union/
integration of the logical (yang) and intuitive (yin) halves of the brain/ mind.
Idebenone - Organ protector
As our organs age or are damaged, we age and are damaged. Over a lifetime, blood
flow to our organs diminishes due to arteriosclerosis and less efficient heart
pumping. This reduces oxygen dependent energy production needed for repair,
reproduction, and normal function of the organ cells. Free radical damage
accumulates over time, leaving ever more dead, dying or dysfunctional cells
At some point a critical threshold is reached when too many cells within an
organ are dysfunctional, and they can no longer sustain the organ's life and
function. Then the organ- heart, brain, liver etc. fails. Idebenone protects
organs in many ways, it cushions them against hypoxic (low oxygen) and/ or
ischemic (poor blood flow) damage. Idebenone enhances both normal and hypoxic
ATP energy generation. Each cell in our organs must produce the energy it needs
for life and health, cells cannot "borrow" energy from each other.
Idebenone - The free radical quencher
Idebenone is a powerful antioxidant, more so than CoQ10, and in some studies is
30 to 100 times more effective, than vitamin E or vinpocetine as a free radical
quencher within the brain cells. Idebenone lessens the free radical induced
Mitochondrial DNA damage that accumulates acceleratingly over a lifetime,
slowing organ damage and aging.
A 1995 study in the Journal of Transplantation compared the organ preserving
effects of CoQ10 and Idebenone. The study measured various factors, such as free
radical membrane lipid damage, cell protein damage and cellular energy
production under hypoxia conditions. The results showed Idebenone to be
dramatically more effective than CoQ10 at preserving liver tissue under
conditions identical to that endured by whole livers "harvested" and stored
(briefly) before transplant to another person. The study recommended using
Idebenone to increase the transplant viability of human livers donated for organ
transplant. Why not use Idebenone to increase your own organ viability, while
you still have the use of them!
Protection against excitatory amino acid neuro toxicity
Glutamic acid and aspartic acid are the two chief excitatory amino acid
neurotransmitters in the human brain. Without them we would be "mental
vegetables. Yet under certain conditions, e.g. stroke or traumatic brain injury-
excessive amounts of excitatory amino acids accumulate in the fluid surrounding
brain cells, causing damage and even death to nerve and glial cells through free
Excitatory amino acid toxicity is at least partly responsible for the
neurotoxicity of the recreational drug "Ecstasy or MDMA." Studies over the past
30 years have also shown that excessive dietary intake of excitatory amino acids
may also damage brain structure/ function, especially in children or sensitive
The two main dietary sources of excitatory amino acids are the flavor enhancer
MSG (monosodium glutamate) and the artificial sweetener aspartame (Nutrasweet).
Also many processed foods (e.g. canned soups, dry roasted spiced peanuts, beef/
chicken bouillon, canned tuna, spices etc.) contain "hydrolized vegetable
protein, yeast extract, soy protein isolate" and similar ingredients that are
mostly excitatory amino acids.
In studies with various types of nerve cell, as well as oligodendroglial cells
(which make up the protective myelin sheaths surrounding many nerves, the
so-called "white matter" of the brain). Idebenone has shown dramatic protective
effects against glutamate toxicity.
With all these powers, Idebenone should rightfully take its place in the first
rank of anti-aging/ nootropic/energizer drugs, along with Hydergine, Piracetam,
vinpocetine, deprenyl, and GH3.
Who can benefit from Idebenone?
1. Healthy people wishing cognitive enhancement and brain energizer effects (it
synergizes well with piracetam, vinpocetine and Hydergine).
2. Stroke victims wishing to improve memory, emotional or speech disturbances.
3. Alzheimer's and cerebrovascular dementia patients.
4. Those preparing for major surgery, especially brain, heart, liver or kidney.
5. People with heart energetics problems, e.g. cardiomyopathy, ischemic heart
disease, congestive heart failure. 3 to 6 tablets (45mg each) daily.
6. People with myelination problems, e.g. multiple sclerosis or "white matter"
7. Those seeking to increase their general energy and vitality levels.
8. People with especially high endurance energy needs, e.g. cross country
skiers, long distance runners, cyclists, swimmers etc.
9. Those at risk of EAA brain damage, e.g. people who routinely consume large
amounts of aspartame sweetened foods/ drinks, or those who routinely eat MSG or
"hydrolyzed vegetable protein" containing restaurant or prepared foods.
10. People wishing to enhance the brain serotonin benefits of tryptophan
5-hydroxy-tryptophan supplements or SSRI drugs, such as Prozac, Paxil, Zoloft or
11. Those suffering acute or chronic liver damage from poison mushrooms, toxic
chemicals, hepatitis etc
12. People desiring a "long haul" broad-spectrum anti-aging drug. Idebenone
synergizes well with deprenyl, Hydergine, GH3.
Because of its synergy with other life extension drugs, those also taking any or
all of Hydergine, Piracetam, vinpocetine, deprenyl, GH3 may benefit from even
just one 45mg tablet a day, especially if taken regularly on a long-term basis.
Because idebenone is fat soluble, it is best taken with a fat rich meal.
Numerous studies have shown that idebenone is well distributed through-out the
body after absorption, accumulating in cellular and organelle membranes, as well
as in the electron transport chain, exactly where it does the most good!
