Coenzyme Q10 and NADH and Chronic Fatigue Syndrome

Richard Antiaging March 4, 2020July 3, 2020 0 Comment

DNA strand — Basically, our efforts to avoid or delay the onset of the various pathologies associated with increasing age involve managing the effects of cellular bio-energetic disturbances, oxidative stress, and mitochondrial dysfunctionMitochondrial dysfunction is the loss of efficiency in the process of ATP energy production. As such, mitochondrial dysfunction is a factor in the ageing process and in virtually all chronic diseases including cancer, cardiovascular diseases, chronic fatigue syndrome and fibromyalgia, diabetes and metabolic syndrome, and neurodegenerative diseases. Coenzyme Q10 is an essential component in the mitochondrial production of ATP energy.... Read more about this term.

Like Coenzyme Q10, NAD+/NADH is essential for life. Without NAD+/NADH, the cells will not produce energy and will die.
Like Coenzyme Q10, NAD+/NADH levels decrease as we get older.

Coenzyme Q10 and NAD+/NADH and Chronic Fatigue Syndrome

The results of a 2015 Spanish study indicate that Coenzyme Q10 and NADH supplementation could be a beneficial treatment of chronic fatigue syndromeChronic fatigue syndrome (CFS) is a complicated disorder with an unknown cause. CFS is characterized by persistent fatigue that does not improve with rest and that cannot be explained by any identifiable medical condition. CFS is also known as myalgic encephalomyelitis (ME) and systemic exertion intolerance disease (SEID). It is sometimes abbreviated ME/CFS. CFS patients typically have low levels of...

High-Selenium Yeast Supplements and Coenzyme Q10

Professor Urban Alehagen writes that a deficiency of selenium may restrict the cells’ ability to get optimal concentrations of Coenzyme Q10. Moreover, the cells are dependent upon adequate concentrations of Coenzyme Q10 to achieve optimal function of selenium in the body. There seems to be a special interrelationship between Coenzyme Q10 and selenium that can be exploited clinically [Alehagen & Aaseth].

Coenzyme Q10 Supplementation and Beyond

We can take a daily Coenzyme Q10 supplement, of course, and we should. However, we should be very careful.

Commercially available CoQ10 supplements vary considerably in their formulation and in their absorption and bio-availability. A cheap 30-cents-per day CoQ10 supplement at the supermarket or drugstore is most likely a poorly absorbed and ineffective supplement.

As consumers of Coenzyme Q10 supplements, we must be ultra-careful in evaluating the marketing claims for CoQ10 absorption and efficacy. The nutritional supplements market is a largely unregulated one. It is up to us to do due diligence before buying a CoQ10 product.

All of the CoQ10 products on the market are not equally good. There is very considerable variability in the formulation and solubilization of Coenzyme Q10 with the result that there is also great variability in the absorption and bio-availability of Coenzyme Q10. It is important to remember that the less expensive CoQ10 product is not a good buy if we do not absorb any or much of the active ingredient.

Coenzyme Q10’s Anti-Inflammatory Effects

Richard Cardiovascular Health, Inflammation December 2, 2019March 19, 2020 0 Comment

Two independent meta-analyses of the available research literature have shown that Coenzyme Q10 supplementation is associated with healthy levels of bio-markers for chronic systemic inflammation [Zhai 2017; Fan 2017].

Chronic inflammation – a persistent low-grade inflammation – can have deleterious effects throughout the body. Over time, it can result in tissue damage.
Chronic inflammation is something different from acute inflammation, which is the immune system’s short-term response to an injury or an infection.
Chronic low-grade inflammation has been linked to increased risk of heart disease, stroke, diabetes, and metabolic disorders [Zhai 2017].
The extent of chronic low-grade inflammation can be measured by testing for the blood levels of known bio-markers for inflammation [Zhai 2017].

Three times 100 milligrams of Coenzyme Q10 per day added to conventional heart failure medicine improves the patients’ quality of life and chances of survival as compared to placebo together with conventional treatment.

Heart failure is what happens when the heart is no longer able to pump out blood as strongly as it should. It occurs when the heart is too weak or too stiff to fill up with blood and pump out blood efficiently. It is characterized by reduced functional capacity and reduced quality of life:

Reduced ability to exercise and do work
Shortness of breath
Swelling in the lower extremities
Weakness and fatigue from exertion

Heart failure is one of the most costly medical conditions in terms of complications and hospitalizations. The costs of medical care for heart failure patients is expected to rise from $30 billion per year in 2018 to nearly $70 million by 2030 [Bhatt & Butler 2018].

The best thing about Coenzyme Q10 adjuvant treatment of heart disease is that the CoQ10 treatment is a positive treatment. It does not block or reduce any neurohormonal activities in the body; instead, it enhances mitochondrial function in the process of cellular ATP energy production. And it provided antioxidant defense of the heart muscle cells. Pictured here: Dr. Svend Aage Mortensen, lead researcher on the Q-Symbio Study.
