Mitochondria are the small
powerhouse organelles that control the energy output for each of the trillions
of cells that function synergistically within the human body. Every cell houses
dozens to hundreds of mitochondria, depending on the particular function and
energy requirement of the component organ. More than 85% of the oxygen
contained in every breath is consumed by these tiny energy producers, so it is
easy to understand how low mitochondrial function typically seen with aging can
lead to low energy levels and ultimately cellular death.
Cutting edge research published in
the Journal of Nucleic Acids and Metabolism furnishes details to explain
that the naturally occurring antioxidant alpha lipoic acid can significantly
reduce mitochondrial decay and boost energy levels to improve longevity parameters
in aging humans.
Alpha Lipoic Acid Reduces Free Radical Stress and Improves Energy Production
Since the early 1970`s scientists
have proposed and validated the `mitochondrial
theory of aging` that demonstrates how a lifetime of accumulated damage to
mitochondrial DNA leads to increased free radical stress and lowered cellular
energy production and chronic disease. Researchers examined aging mice that
were broken into two groups, one supplemented with alpha lipoic acid in their
drinking water and the other a control group, for a period of 30 days. Both
groups were tested for metabolic functions relating to glucose metabolism,
energy production and antioxidant status.
Authors of the study found that
the alpha
lipoic acid supplemented group experienced mitochondrial biogenesis, a
process that rejuvenates and replaces damaged and aging mitochondria. Prior
bodies of research postulated that mitochondrial regeneration and genesis were
not possible and cell death was always the final result of mitochondrial
dysfunction. Through a very intricate metabolic process, lipoic acid
supplementation was found to improve body composition, glucose tolerance, and
energy expenditure in the aged mice.
Alpha Lipoic Acid May Aid Weight Management and Improve Insulin Control
Researchers noted this was the
first time a natural compound was able to effectively revitalize mitochondria
in aging cells, and concluded
that alpha lipoic acid supplementation “increases
lean mass loss possibly by suppressing protein synthesis in the skeletal muscle
by down-regulating the mTOR signaling pathway. Thus, lipoic acid may be a
promising supplement for treatment of obesity and/or insulin resistance in
older patients.”
Subsequently, research conducted
by Dr. Bruce Ames found that combining the bioactive `R` isomer of lipoic acid
and acetyl-l-carnitine decreases oxidative damage leading to mitochondrial
decay and may help prevent degenerative diseases of aging including cancer,
cognitive decline (dementia) and diabetes while restoring the vital energy
needed to live an active lifestyle. Nutrition experts recommend supplementing
with `R` alpha-lipoic acid (100 – 300 mg daily) and acetyl-l-carnitine (1000 mg
daily) to restore energy levels lost to mitochondrial decline.
