In 2010 I became aware of 2 major advancements for anti-aging and disease prevention. These 2 breakthroughs alone are huge and would have enough benefits to your health by themselves, but taken with a few other nutraceuticals, have the potential to radically improve your health for 2011 and beyond. By radical, I mean levels of health that could only be had in youth.
If you are 40 years or older listen up.
In aging, the 2 things that affect us the most are oxidative stress and energy depletion.
In recent blogs I have focused on the amazing benefits of Protandim, which deals effectively with oxidative stress. Scientific research has validated oxidative stress, which is damage to your body’s cells by free radicals, as the root cause at the cellular level of aging.
In fact, studies show that metabolic wear and tear caused by free radicals in cells accelerates aging, the problems associated with aging, and contributes to more than 200 health conditions.
Once you slow down the damage and deal with cleaning up waste products efficiently with Protandim, then the next big area is energy production and/or depletion.
Energy is produced by the mitochondria in our cells. As we age we lose the number of mitochondria present in our cells, unless we exercise our brains out, which hardly anyone does. As the numbers diminish or get damaged by free radicals we become more and more feeble until we just run out of energy and die. It's that critical to our well being.
The second biggest breakthrough for 2010 is the compound PQQ, or (pyrroloquinoline quinone).
PQQ has been shown to promote memory, attention, and cognition in maturing individuals and more importantly, INCREASE THE NUMBER OF MITOCHONDRIA THAT YOU HAVE IN YOUR CELLS.
Life Extension Foundation has brought this research to light and manufactures the product. Check out both the video and the article and consider what this would mean if you could incorporate both of these breakthroughs together. Mitochondrial Energy Booster.

Rejuvenate Your Cells by Growing New Mitochondria
Mitochondrial dysfunction is a primary cause of age-related decline. In a revealing study, a team of researchers showed that muscle tissue of a 90-year-old man contained 95% damaged mitochondria compared to almost no damage in that of a 5-year-old.
When one looks at the boundless energy of a child compared to an elderly person, the devastating impact of mitochondrial degradation becomes instantly apparent. A myriad of recent scientific reports link defective and deficient mitochondria to virtually all degenerative diseases including Alzheimer’s, type 2 diabetes, heart failure, and cancer.
Up until now, the best we could do was protect and improve the function of existing mitochondria using nutrients like L-carnitine, lipoic acid, and coenzyme Q10.
In an unprecedented breakthrough, a compound has been discovered that promotes the growth of new mitochondria structures within aging cells!
In this article you will discover how this novel compound can help reverse cellular aging by activating genes that stimulate mitochondrial biogenesis, which means the generation of new mitochondria. The more functional mitochondria you have in your cells, the greater your overall health and durability.
Mitochondria are the only cell components (other than the nucleus) to possess their own DNA. This means mitochondria have the ability to replicate and increase their number within a single human cell.
Human cells may house anywhere from 2 to 2,500 mitochondria, depending on tissue type, antioxidant status, and other factors.
A growing number of biologists espouse the theory that mitochondrial number and function determine human longevity. To put it simply, the more functional mitochondria you have in your cells, the greater your overall health and durability.
The problem is, as we age, our mitochondria degrade and become dysfunctional. Age-related destruction of the mitochondria occurs more rapidly than in other cell components, meaning that for most people it is loss of functional mitochondria, that ultimately leads to personal extinction.
The challenge aging humans face is that methods to increase the generation of new mitochondria are difficult to adhere to. Up until recently the only natural ways to stimulate mitochondrial biogenesis were calorie restriction or exhaustive physical activity.
A natural agent with the power to safely induce mitochondrial biogenesis would mark an extraordinary advance in the quest to halt and reverse cellular aging. A compound called pyrroloquinoline quinone, or PQQ, is rapidly emerging as that nutrient.
PQQ: A Quantum Leap That May Reverse Cellular Aging
PQQ (pyrroloquinoline quinone) plays a critical role across a range of basic life functions. As an ultra potent antioxidant, it provides extraordinary defense against mitochondrial decay: PQQ’s chemical structure enables it to withstand exposure to oxidation up to 5,000 times greater than vitamin C.
When combined with CoQ10, research shows just 20 mg per day of PQQ can significantly preserve and enhance memory, attention, and cognition in aging humans.
But the most exciting revelation on PQQ emerged early in 2010, when researchers found it not only protected mitochondria from oxidative damage—it also stimulated growth of new mitochondria!
PQQ Is an Essential Micronutrient
PQQ is ubiquitous in the natural world. It has been found in all plant species tested and is present in human milk. Humans, however, are not capable of synthesizing it. This has led researchers to classify PQQ as an essential micronutrient.
PQQ’s potential to stimulate mitochondrial biogenesis was foreshadowed by early findings indicating its central role in growth and development across multiple forms of life.
PQQ has been shown to be a potent growth factor in plants, bacteria, and higher organisms. Pre-clinical studies reveal that when deprived of dietary PQQ, animals exhibit stunted growth, compromised immunity, impaired reproductive capability, and most importantly, fewer mitochondria in their tissue. Rates of conception, the number of offspring, and survival rates in juvenile animals are also significantly reduced in the absence of PQQ.
When PQQ is introduced back into the diet it reverses these effects restoring systemic function while simultaneously increasing mitochondrial number and energy efficiency.
These compelling data prompted a team of researchers at the University of California-Davis to specifically analyze PQQ’s influence on cell signaling pathways involved in the formation of new mitochondria.
Their work, published last year, led to several extraordinary discoveries. They found that PQQ’s critical biological roles stem from its ability to activate genes directly involved in cellular energy metabolism, development, and function.
Their findings shed light on results from favorable prior studies. For example, PQQ deficiency in juvenile mice results in a 20-30% reduction in the number of mitochondria in the liver, elevated blood glucose, and impairment in oxygen metabolism.26 These are hallmark indicators of mitochondrial dysfunction. Yet when PQQ was put back into the diet these pathological effects were reversed along with an increase observed of new mitochondria.
This and additional animal model data28 taken together confirm PQQ’s ability to significantly boost mitochondrial number and function—a key to cellular anti-aging and longevity.
The sidebar below reveals the complex mechanisms by which PQQ activates genes that stimulate mitochondrial biogenesis.
Protecting Against Mitochondria-generated Free Radicals
As the primary energy engines of our cells, the mitochondria rank among the structures most vulnerable to destruction from oxidative damage.
The formidable free radical-scavenging capacity of PQQ furnishes the mitochondria considerable antioxidant protection.
At the core of this capacity is an extraordinary molecular stability. As a bioactive coenzyme, PQQ actively participates in the energy transfer within the mitochondria that supplies the body with most of its bioenergy (like CoQ10).
Unlike other antioxidant compounds, the stability of PQQ allows it to carry out thousands of electron transfers without undergoing molecular breakdown. It has been proven especially effective in neutralizing the ubiquitous superoxide and hydroxyl radicals. According to the most recent research, “PQQ is 30 to 5,000 times more efficient in sustaining redox cycling . . . than other common [antioxidant compounds], e.g. ascorbic acid.”
Protection Against Brain Aging
PQQ has been shown to optimize function of the entire central nervous system. It reverses cognitive impairment caused by chronic oxidative stress in pre-clinical models, improving performance on memory tests.40 It has also been shown to safeguard a gene involved in the development of Parkinson’s disease (called DJ-1) from self-oxidation—an early step in the onset of Parkinson’s.
Reactive nitrogen species (RNS), like reactive oxygen species, impose severe stresses on damaged neurons. They arise spontaneously following stroke and spinal cord injuries and have been shown to account for a substantial proportion of subsequent long-term neurological damage. PQQ directly suppresses RNS in experimentally induced strokes. It also provides additional protection by blocking gene expression of inducible nitric oxide synthase, a major source of RNS, following spinal cord injury.
PQQ protects brain cells against damage following ischemia-reperfusion injury—the inflammation and oxidative damage that result from the sudden return of blood and nutrients tissues deprived of them by stroke. Given immediately before induction of stroke in animal models, PQQ significantly reduces the size of the damaged brain area. This finding implies that if a person were to suffer a temporary loss of cerebral blood flow due to cardiac arrest, stroke, or trauma, that having PQQ in their body would afford considerable protection against permanent brain damage.
PQQ also beneficially interacts with brain neurotransmitter systems. In particular, PQQ protects neurons by modifying the important NMDA receptor site. NMDA is a powerful mediator of “excitotoxicity,” a response to long-term overstimulation of neurons that is associated with many neurodegenerative diseases and seizures. PQQ protects against neurotoxicity induced by other toxins, including mercury.
A mounting body of evidence points to PQQ as a potent intervention in Alzheimer’s and Parkinson’s disease. Both are triggered by accumulation of abnormal proteins that initiate a cascade of oxidative events resulting in brain cell death.
How PQQ Generates New Mitochondria
Mitochondrial biogenesis can be defined as the growth and division of pre-existing mitochondria. This phenomenon is not only accompanied by increased mitochondria numbers, but also their size and mass.
Mitochondrial biogenesis requires the coordinated synthesis and import of 1,000-1,500 proteins where they facilitate the production of healthy new mitochondria.
Mitochondrial biogenesis occurs through the combined effects of genes activated by PQQ via the following three mechanisms:
* PQQ increases expression of peroxisome proliferator-activated receptor gamma coactivator 1-alpha or PGC-1α. PGC-1α is a “master regulator” gene that mobilizes your cells’ response to various external triggers. It directly activates genes that boost mitochondrial and cellular respiration, growth, and reproduction. Its capacity to modulate cellular metabolism at the genetic level favorably affects blood pressure, cholesterol and triglyceride breakdown, and the onset of obesity.
* PQQ activates a signaling protein known as cAMP-response element-binding protein or CREB. The CREB gene plays a pivotal role in embryonic development and growth. It also beneficially interacts with histones, molecular compounds shown to protect and repair cellular DNA. CREB also stimulates the growth of new mitochondria.
* PQQ regulates a recently discovered gene called DJ-1. As with PGC-1α and CREB, DJ-1 is intrinsically involved in cell function and survival. It has been shown to prevent cell death by combating intensive antioxidant stress and is of particular importance to brain health and function. DJ-1 damage and mutation have been conclusively linked to the onset of Parkinson’s disease and other neurological disorders.
PQQ prevents development of alpha-synuclein, the protein responsible for Parkinson’s disease. It also protects nerve cells from the oxidizing ravages of the Alzheimer’s-causing amyloid-beta protein. A 2010 study revealed that PQQ could prevent formation of amyloid-beta molecular structures. These effects were traced to three distinct biochemical mechanisms described in the sidebar above.
PQQ has also been shown to protect memory and cognition in aging animals and humans. It stimulates production and release of nerve growth factor in cells that support neurons in the brain. This may partially explain why PQQ supplementation of aging rats resulted in marked retention of their maximum memory function.
In humans, supplementation with 20 mg per day of PQQ resulted in improvements on tests of higher cognitive function in a group of middle-aged and elderly people. These effects were significantly amplified when the subjects also took 300 mg per day of CoQ10. Presumably a lower dose of the more absorbable ubiquinol form of CoQ10 would provide the same benefit as 300 mg of ubiquinone.
PQQ has also been shown to protect memory and cognition in both aging animals and humans.
As with strokes, damage in heart attacks is inflicted via ischemia-reperfusion injury. Ischemia-reperfusion means loss of blood flow (ischemia) to part of the body and the subsequent re-flow (reperfusion) when blood flow is restored. Cells are injured when blood flow is interrupted and often sustain even greater damage when blood flow is suddenly restored.
Supplementation with PQQ reduces the size of ischemia-reperfusion damaged areas in animal models of acute myocardial infarction (heart attack). This occurs whether the supplement is given before or after the ischemic event itself.
To further investigate this potential, researchers at the VA Medical Center at UC-San Francisco compared PQQ with metoprolol, a commonly prescribed beta blocker that is standard post-heart attack clinical treatment.60 Given alone, both treatments reduced the damaged areas’ size and protected against heart muscle dysfunction. When they were given together, the left ventricle’s pumping pressure was enhanced. The combination also increased mitochondrial energy-producing functions—but the effect was small compared with the better response seen with PQQ alone!60 And only PQQ favorably reduced lipid peroxidation. The remarkable conclusion: “PQQ is superior to metoprolol in protecting mitochondria from ischemia/reperfusion oxidative damage.”
Subsequent research from the same team has demonstrated that PQQ helps heart muscle cells resist acute oxidative stress. The mechanism? Preserving and enhancing mitochondrial function.
Why Mitochondria Are So Vulnerable to Free Radical Damage
The death spiral of our mitochondria is accelerated by the very physiological function they must perform, i.e. energy production.
As the cell’s power generators, mitochondria are the site of enormous and constant oxidative activity that spews out toxic free radicals. To make matters worse, relative to nuclear DNA, mitochondrial DNA possesses few defenses against free radical damage.
DNA in the cell’s nucleus is protected by numerous “guardian” proteins that blunt the impact of free radicals. No such repair systems exist to protect mitochondrial DNA.
Nuclear DNA also enjoys superior structural defenses. It is housed within a protective double-membrane that separates it from the rest of the cell. This double-membrane is complemented by a dense matrix of filament proteins called the nuclear lamina, a kind of hard shell casing to further buffer DNA from external impacts.
By comparison, mitochondrial DNA is left almost entirely exposed: it attaches directly to the inner membrane where the mitochondria’s electrochemical furnace rages continuously, generating an enormous volume of toxic reactive oxygen species. This is why supplementation with lipoic acid, carnosine, and other mitochondrial-protecting antioxidants is so important.
The extraordinary antioxidant capacity of PQQ represents a powerful new intervention that may effectively reinforce the mitochondria’s meager defenses.
Cellular aging is intimately associated with the decline in mitochondrial number and functionality. Nutrients that provide protection to existing mitochondria include resveratrol, carnosine, lipoic acid, L-carnitine, and CoQ10.
During the course of normal aging, however, the number of functional mitochondria pathologically diminishes, leading to a host of debilitating disorders followed by death of the organism.
For the first time in scientific history, a natural compound called PQQ is available to increase the functionality of existing mitochondria while promoting the generation of new mitochondria inside aging cells.
