You’ve been told that glutathione increases
energy on a cellular level. How does it do
this? Since glutathione is not the actual
fuel for the “engines” or “energy factories”
of our cells, what part does it play in the
creation of cellular energy?
These are questions we would all like answers
to, but not if they make us feel like we’re
back in Chemistry 101! Hopefully, what you read
below will provide a non- technical explanation for
these questions.
The Tiger in Your Tank Is Called ATP
It’s obvious that all cells must produce energy to
survive. We know that the “gasoline” or “electricity”
that powers our cells is called ATP (adenosine
triphosphate). If your car runs out of gas, it can
sit for a while until you replenish the supply. Not so
with our cellular fuel. Our cells simply cannot survive
unless they have a continual, suffcient supply
of “cellular gasoline” or ATP. So the process of
creating fuel in each and every cell must go
on constantly.
A single cell may have a couple of hundred
energy factories or cellular power plants called
mitochondria or it may contain thousands of
them. Your hard-working heart cells have been
estimated to have 5,000 mitochondria each1
!
The complex process of turning nutrients into
ATP in the mitochondria depends on many
oxidation and reduction reactions.
Redox is the shorthand term for the chemical
reaction where atoms are changed by
either losing elections (oxidation) or gaining
electrons (reduction).
The Process
Understanding the exact process of ATP creation
didn’t happen until 1937. Hans A. Krebs fnally
fgured out a metabolic pathway in the cells that
explained how energy is created. There were many
scientists who played a key role in understanding
how this pathway worked, but because Krebs had the
insight that the pathway was a cycle, the process
was named for him and is usually called the Krebs
cycle. You will also read of it as
the “citric acid cycle” or the tricarboxylic
acid cycle (TCA) or occasionally, the Szent-
Györgyi-Krebs cycle (adding the name of
the scientist who mapped out many of the
molecules and the sequence of reactions of
the Krebs cycle). We are including a diagram of the eight major
steps in the energy cycle.
Energy Production
Since we are not doing Chemistry 101, describing this process
could be as simple as saying it’s a metabolic
dance of electrons being transported and
transferred, through complex processes of
reduction and oxidation. Remember that
transferring (or grabbing!) electrons is also
what starts the cycle of free radical damage.
The Role of Glutathione
Oxidation is like a fame, wonderful when
harnessed, dangerous when out of control.
When we are young, the oxidation necessary
for energy production is highly effcient
with only a small amount of oxygen not
utilized. Even this minor oxygen loss (1-3%)
unfortunately results in the production of free
radicals. And this is where glutathione comes
in to neutralize those free radicals .
A one-to-three percent oxygen loss causing
free-radical production doesn’t sound too bad,
does it? But say you are no longer 20 years of age
and correspondingly, your cellular mitochondria are
not as effcient as they once were. More and
more free radicals are generated in the oxidative
energy process and they are, in turn, damaging
the mitochondria themselves.
The powerful antioxidant, glutathione,
quenches a number of free radicals, including
the highly dangerous hydroxyl radical by
donating an electron. Glutathione itself does
not become a free radical even though it has
given up an electron.
No wonder it is called the Master Antioxidant !
Now that it is quenched, the extremely
harmful hydroxyl radical is halted from its real
dirty work: generating other free radicals like
peroxynitrite and the radicals of oxidized fats
(lipids).
Glutathione has just halted a literal cascade
of free radicals by quenching the hydroxyl
free radical. But you need to know just
what a favor glutathione has done for you in
preventing peroxynitrite production.
Peroxynitrite is truly pernicious!
Martin L. Pall, PhD, professor of Biochemistry
and Basic Medical Science at Washington
State University stated: “Peroxynitrite reacts
with and inactivates several of the enzymes
in mitochondria so that mitochondrial and
energy metabolism dysfunction is one of
the most important consequences of elevated
peroxynitrite.”2
Translation: When the mitochondria have suffered enough free
radical damage as to become dysfunctional,
energy production is impaired. Your cells do not
get the amount of energy they need to function
properly. Your cells may function at a level below
the optimum although you probably won’t
feel it.
There is yet one more free-radical mitochondrial
consequence as a result of low glutathione
levels that you “will” be aware of. Richard
Van Konynenburg, PhD, wrote: “The resulting
partial blockades in the Krebs cycles and the
respiratory chains in the red, slow-twitch
skeletal muscle cells decrease their rate of
production of ATP. Since ATP is what powers
muscle contractions, the lack of it produces
physical fatigue. It becomes chronic because GSH [glutathione] remains depleted.”3
You might think of free radicals as a band of
marauders circling an oil tanker, preparing
to hijack the precious commodity that fuels
cars and trains and pretty much the entire
Western world. Glutathione molecules could
be considered a group of highly effcient
bodyguards—handing out electrons and
turning vicious marauders into mild-mannered
bystanders.
Glutathione
Praise from Dr. Keller As you understand this
intricate energy creation process, perhaps you
will appreciate more a statement by the creator
of MaxGXL, Dr. Robert H. Keller. Dr. Keller said that
glutathione is “critical to cell functions such as the
TCA (Kreb) cycle and then the respiratory chain that
uses 4 molecules of ATP to generate 32 molecules
of ATP.”
Is it vital for you to have those glutathione
bodyguards on energy duty? Van Konynenburg
certainly thinks so as he wrote, “ GSH [glutathione]
plays very important roles in maintaining
mitochondrial function and integrity.”4
Perhaps it’s enough to remember that
glutathione is there to assure that the
creation of cellular energy is not hampered
by free radical damage. While this is not by
any means the only role glutathione plays
in keeping your body running smoothly, it
is a vitally important role. Now you have
one more reason to appreciate Dr. Keller’s
marvelous, patented product!
