Coenzyme Q10, commonly referred to as ubiquinol or Q10, can be found in every cell in your body and plays a critical role in energy production and as an antioxidant.

Protein is naturally present in meats and fish products and can also be manufactured in laboratories. Protein acts as a natural lipid-soluble antioxidant that provides energy for cells, supports immune response, and protects against oxidative damage.

What is Coenzyme Q10?

Coenzyme Q10 (CoQ10) is a fat-soluble anthraquinone produced naturally in yeast cells as well as animal livers, kidneys, and hearts. This compound plays an essential role in cell energy transfer as well as serving as an antioxidant protection from oxygen molecules damaging our cells. CoQ10 supplements have proven themselves helpful in treating mitochondrial disorders, heart disease, migraine headaches and high blood pressure conditions among others.

Ubiquinol and ubiquinone are two forms of coenzyme Q10. While our bodies can convert back and forth between these forms, ubiquinol typically accumulates more in bloodstream and tissue environments than ubiquinone.

Ubiquinone plays an essential role in several metabolic reactions, including protein synthesis, gene regulation, and the production of ATP. As an antioxidant it helps prevent oxidative stress and aging; studies have also indicated its effectiveness in treating Parkinson’s disease and cardiovascular disease as well as cancer and diabetes. Although various methods exist for producing this coenzyme Q10 precursor such as chemical synthesis or fermentation processes are possible; fermentation stands out due to its many advantages – producing large quantities without toxic residues remains one of the best methods.

How is Coenzyme Q10 Produced?

Coenzyme Q10 (CoQ10), more commonly referred to as ubiquinone-10, can be found in almost all cells and plays an essential role in energy generation and free radical scavenging. CoQ10 may also help delay or slow aging while possibly protecting against heart disease, cancer, diabetes and other ailments.

CoQ10 is produced by numerous microorganisms, plants and animals alike; as well as by human cells. CoQ10 acts to protect lipoproteins from oxidation while contributing to energy generation within cells and is an antioxidant capable of protecting them against any oxidative damage to cell membranes, DNA or other structures within our bodies.

Oxidative modification of low-density lipoproteins in arterial walls leads to atherosclerosis. Reduced CoQ10H2 is believed to hinder this oxidation by reacting with a-tocopherol and producing a-TO* (Fig. 3). This reaction is catalyzed by polyprenyl diphosphate transferases capable of accepting isoprenoid chains of different lengths for regeneration (see also here and here).

Traditional approaches to metabolic engineering for CoQ10 production have focused on chemical mutation and manipulation of substrate flux [3, 47]. With synthetic biology now providing us with new tools that allow us to modify and enhance this biosynthesis reaction, metabolic engineering may become even more efficient at producing CoQ10.

What is the Role of Coenzyme Q10 in the Human Body?

Coenzyme Q10 can be found in every cell in your body and plays an essential role in energy production, acting both as an antioxidant and fighting damaging particles called free radicals – these harmful particles damage cells, interfere with DNA and cause diseases that damage our health in many ways. Coenzyme Q10 helps protect against heart disease as well as other conditions by improving energy production within cells while acting as an antioxidant.

Coenzyme Q10 in its ubiquinol form is an effective fat-soluble antioxidant, proven to prevent LDL (“bad”) cholesterol oxidation in bloodstream. Furthermore, studies have revealed its ability to decrease mitochondrial lipid peroxidation rates and protect membrane proteins and DNA against damage caused by peroxidation processes.

Coenzyme Q10 is produced naturally in our bodies, yet dietary intake may be low. Supplemental forms of this nutrient can be found in meat (particularly liver and heart), fish, soybean, canola and peanut oils; nuts; and vegetables. Furthermore, small number of randomized controlled trials have investigated effects of oral coenzyme Q10 supplementation for three months on markers of inflammation such as CRP and interleukin-6 with mixed results from these trials; larger scale studies will need to be completed in order to fully establish their effectiveness.

What is the Role of Coenzyme Q10 in the Treatment of Parkinson’s Disease?

Ageing brains exhibit changes on histological, biochemical and physiological levels, with mitochondrial structures often being damaged due to oxidation damage from free radicals oxidized during cell metabolism resulting in neurodegenerative conditions like Parkinson’s. Coenzyme Q10 supplementation may provide benefit in treating such disorders (see Biological Activities).

CoQ10 is an integral component of mitochondrial energy supply processes, shuttling electrons between complexes I and II of the respiratory chain. Furthermore, CoQ10 acts as an excellent lipid-soluble antioxidant to protect organelle membranes against free radical damage that could otherwise result from free radical exposure.

Studies on preclinical Parkinson’s Disease models have demonstrated the positive impact of supplementing CoQ10 on dopamine neurons, improving motor-related symptoms and slowing progression. A phase II clinical trial with patients receiving 300, 600 or 1200 mg/day of CoQ10 experienced stabilization and slowing of progression as measured by the Unified Parkinson’s Disease Rating Scale (UPDRS), with larger phase III randomized controlled studies planned; additionally intrastriatal administration of CoQ10 has been shown to slow progression in small animal models, with trials beginning to test its effect in human subjects.

What is the Role of Coenzyme Q10 in the Treatment of Heart Failure?

Coenzyme Q10 is an essential nutrient, playing numerous essential roles within the body. It aids with energy production in mitochondria and protects against oxidative damage to cells. Furthermore, Coenzyme Q10 serves as an antioxidant which neutralizes free radicals while replenishing other antioxidants like a-tocopherol (vitamin E) and ascorbate (vitamin C).

CoQ10 is an integral cofactor in the electron transport chain that generates cellular energy in the form of ATP. It facilitates electron movement from complexes I and II of mitochondrial respiratory chain complex III; for optimal functioning of high energy-consuming tissues such as heart muscle or skeletal muscle it requires sufficient levels of CoQ10.

CoQ10 has been shown to reduce blood lipid peroxidation and enhance mitochondrial function in humans, as well as being effective at treating patients with heart failure. Multiple randomized and placebo-controlled trials have demonstrated its benefits in treating this disease – supplementation has significantly improved heart failure symptoms and exercise capacity in these patients with HF, while studies suggest its use combined with other treatments could also decrease mortality rates and improve ejection fraction.

What is the Role of Coenzyme Q10 in the Treatment of Hypertension?

Coenzyme Q10 not only plays a vital role in energy production, but it is also an antioxidant which protects cells against free radical damage. It can be found both within our cells as well as foods such as organ meats (heart, liver and kidney), beef, soy oil, sardines mackerel and peanuts. As we age our plasma levels of Coenzyme Q10 begin to decline with supplementation helping restore them; studies show it improves anaerobic exercise performance while simultaneously decreasing low grade inflammation caused by exercise (8-12).

Studies of double blind, randomized controlled trials suggest that supplementing coenzyme Q10 with hypertension could significantly decrease their blood pressure (15-24). This effect is believed to be caused by its ability to enhance endothelial cell function, reduce total peripheral resistance, and enhance blood flow.

Coenzyme Q10 may help stimulate consumption of fatty acids, leading to weight loss and subsequent lower BP (25). Studies with patients taking antihypertensive therapy appear to show it to be well tolerated and does not interact with medications used to treat hypertension; however, more RCTs must be completed to assess these findings further and evaluate different dosages of Coenzyme Q10.

What is the Role of Coenzyme Q10 in the Treatment of Diabetes?

Under both free radical and mitochondrial theories of aging, reactive oxygen species (ROS) oxidative damage to cell structures is one major source of functional decline associated with ageing. CoQ10 acts as an antioxidant to counteract these damaging effects of ROS by supporting mitochondrial ATP production and countering any harmful ROS effects that occur as we age.

Studies have demonstrated that supplemented CoQ10 can significantly improve outcomes of diabetes and its cardiovascular complications by various mechanisms, including protecting cells from oxidative damage, increasing energy metabolism and decreasing blood sugar levels.

One study demonstrated that in vitro supplementation of human liver cells with CoQ10 increased succinate dehydrogenase activity – an enzyme vital to the Krebs cycle – by accepting electrons from flavoprotein in mitochondrial inner membrane and donating them to CoQ10. As a result, increasing energy was achieved.

Another study reported that CoQ10 can significantly enhance glucose tolerance among patients with type 2 diabetes due to its effects on oxidative stress reduction and increased insulin sensitivity, as well as being an excellent endothelial dysfunction inhibitor, both associated with increased oxidative stress levels and diabetes mellitus.
