For the supplemented group, higher values were found at 12 months compared to 6 months, and at 24 months compared to 6 and 12 months.
Both cytosolic antioxidant enzymes Table 4 showed a gradual increase in their activities with age in the two experimental groups, with higher values at 12 months than at 6 months and at 24 months than at 6 and 12 months.
The CoQ 10 -supplemented rats showed higher values at 24 months for catalase and at 6 months for glutathione peroxidase.
The concentration of these cytochromes is shown in Table 4. CCO activity is show in Figure 4. In both groups, the activity of this enzyme showed a gradual decrease with age, with lesser values at 12 months than at 6 months and at 24 months than at 6 and 12 months. The aim of this study was to investigate possible changes during aging in lipid peroxidation and functionality of heart mitochondria, depending on a lifelong supplementation or not with CoQ 10 , in rats fed a diet rich in PUFAs throughout their life.
Thus, we tried to test whether CoQ 10 supplementation might attenuate aging-related oxidative alterations observed in the heart of rats fed a PUFA-rich diet Confirmation of that effect enables the preservation of beneficial aspects of PUFA on health, such as those related to cardiac diseases 6 , 9 , Prior to the analysis of possible effects of CoQ 10 supplementation, it was necessary to assess adaptation of the rats to such supplementation.
In the present study, we found that supplementation led to higher CoQ 10 levels at 12 and 24 months of age in heart mitochondria.
Considering that, besides plasma, liver, and spleen, most of the tissues are resistant to increased amounts of coenzyme Q from exogenous sources 26 , we can state that our lifelong supplementation schedule based on a low CoQ 10 concentration 0.
The analysis of hydroperoxide levels as an indicator of lipid peroxidation reveals that, regardless of the dietary manipulation, cardiac mitochondrial lipid peroxidation was higher at 12 and 24 months than at 6 months of life.
This result agrees with previously reported data 12 , 27 , 28 , and is consistent with the free radical theory of aging of Harman 1.
However, there were important differences between experimental groups with respect to this parameter. Animals fed a PUFA-rich diet and supplemented throughout life with CoQ 10 0.
In addition, although both groups reached the highest hydroperoxide value at 12 months, the nonsupplemented animals maintained this value until 24 months of age, whereas the supplemented animals were able to decrease it significantly. Thus, at 24 months of age, the supplemented animals reached a hydroperoxide value close to that of nonsupplemented animals at 6 months of life.
There are different ways through which CoQ 10 could be able to cause these differences in hydroperoxide levels, such as changes in the mitochondrial fatty-acid profile and therefore its susceptibility to lipid peroxidation, increasing antioxidant defenses or acting on the free radicals sources.
We have studied, partially, all these ways. It has been shown that modifications of the mitochondrial fatty-acid profile can modulate the susceptibility of the mitochondrial membranes to lipid peroxidation during aging In this sense, administration of CoQ 10 has been shown capable of modifying the phospholipid fatty-acid composition in monocytes and granulocytes However, under our experimental conditions, the study of the mitochondrial fatty-acid profile shows that lifelong CoQ 10 supplementation was not able to modify this parameter significantly.
Both experimental groups registered higher levels of saturated fatty acids associated with age and lower monounsaturated fatty acids. This result agrees with previous data reported by our research group 12 for heart in aged rats fed a PUFA-rich diet.
The enzymatic and nonenzymatic components of the antioxidant system studied followed a similar response in both groups with higher levels related to age except coenzyme Q levels in nonsupplemented animals.
Previously, increased cardiac antioxidant levels associated with age have been reported 12 , 29 , It has been postulated that a compensatory antioxidant defense system exists to counteract oxidative stress associated with aging, and therefore some antioxidants would be expected to accumulate, such as α-tocopherol, at the sites in which it is needed Despite the similar pattern followed by both experimental groups with respect to the antioxidant system, there were important differences between them.
For the nonenzymatic antioxidants, α-tocopherol levels were higher, at least at 6 and 12 months of age, in the supplemented animals, and this group also showed a gradual increase associated with age in coenzyme Q content both CoQ 9 and CoQ 10 , whereas the nonsupplemented group showed no age-associated changes in coenzyme Q content.
Results from the present study agree with those of other groups. It is of interest to note that, although our study did not use high CoQ 10 dosages, as other studies 26 , 31 , we found the mentioned increase in α-tocopherol and CoQ 9 concentration. The aforementioned suggest that both acute supplementation of high dosages and chronic administration of low dosages of oQ 10 are able to induce levels of α-tocopherol and CoQ 9.
It is noteworthy that the higher levels of α-tocopherol shown in nonsupplemented month-old animals were not accompanied by a similar pattern in the coenzyme Q contents, and several results indicate that these two lipid-soluble antioxidants are in fact more efficient when acting together Thus, it seems to indicate that old mitochondrial membrane from supplemented animals could be more prepared against oxidative injury than is that from nonsupplemented animals.
To test this hypothesis, we have induced in vitro oxidative stress against these old membranes using the potent free radical generator AAPH.
The results indicate that, despite the similar PUFA content of these membranes and hence a theoretically similar susceptibility to oxidative damage , mitochondrial membranes from old supplemented animals registered lower AAPH-induced hydroperoxide values and therefore proved to be more resistant against oxidative damage.
This result is important because one of the problems with aged cardiac mitochondria is that they are more susceptible to oxidative damage and therefore predispose the heart to greater injury during oxidative insults 3.
With respect to enzymatic antioxidants, both showed the highest activities at 24 months, which we believe is due to an increase in free radical generation at this age, because it has been suggested to be the most important factor for the induction of the activities of these enzymatic antioxidants 2.
Increased catalase activity has been associated with greater resistance to oxidative damage 2 , and it has been suggested that catalase can function as a major pathway for detoxifying H 2 O 2 in cardiac tissue With our data alone, it is difficult to ascertain the mechanisms by which CoQ 10 supplementation can increase the activity of this antioxidant enzyme, and thus this issue needs further study.
Nevertheless, it has been showed that CoQ 10 administration was able to increase in mice heart the gene expression of glutathione S -transferase, another element of the antioxidant system family 5.
We can not rule out that a similar interaction could exist between CoQ 10 and catalase. The third possible way by which coenzyme Q could modulate lipid peroxidation levels is by acting on the free radical source, the mitochondrial electron transport chain METC.
Aging has been associated with decay in mitochondrial respiratory chain activity 28 and an increased rate of mitochondrial O 2. Thus, it has been suggested that there could be an obstruction or partial blockage of electron flow through some respiratory complexes associated with age; therefore, a greater number of free radicals could be generated at these sites along the METC 12 , Results related to cytochrome content and CCO activity obtained in our study agree with the aforementioned.
As has been suggested, this situation could give rise to a possible partial blockage of electron flow and therefore higher free radical production.
Thus, taking together the fact that the antioxidant enzymes activity increase at 24 months compared with 12 months and the fact that CCO activity was the lowest at the oldest age, despite of the similar hydroperoxides values between the two ages, we can suggest that at 24 months of life the generation of free radicals was higher than at 12 months and therefore the oxidative insult.
In contrast, CoQ 10 supplementation appears to improve these age-associated alterations or changes in the METC. Besides a slight effect on cytochromes content, mostly at 12 months of life, CoQ 10 supplementation can increase CCO activity, with respect to that in nonsupplemented animals, throughout life.
In addition, CoQ 10 supplementation led to a higher content of this molecule and its homologue CoQ 9 at the mitochondrial membrane level nonsupplemented animals did not show this effect. This should be important for the METC function, because, as has been widely reported, under physiological conditions, the mitochondrial concentration of coenzyme Q does not saturate the enzymes that use it as a substrate In conclusion, on the basis of these results we can suggest that previously reported positive effects of CoQ 10 supplementation on mean and maximal life span of rats fed a PUFA-rich diet might be a consequence, at least in part, of a lower oxidative stress level and perhaps, to a minor extent, to a smaller decrease in mitochondrial function.
In addition, these results could lead to a better understanding of the beneficial effects on heart function after administration of CoQ 10 , although investigation of different diets and further studies in humans are still needed to elucidate this protective role of CoQ Decision Editor: James R.

A phenomenon associated with the aging process is a general age-dependent decline in cellular Cenzyme capacity that Coenzyme Q and aging agibg tissue to tissue and even from anv to cell within Eye-healthy antioxidant rich foods same afing. This sging eventually forms a tissue bioenergy mosaic. Recent Coenzyme Q and aging by our group All-natural ingredients that Coenzyme Q and aging accumulation of mitochondrial DNA mutations, in conjunction with a concurrent decrease in full-length mtDNA in tissues such as skeletal and cardiac muscle, strongly correlates with decreased mitochondrial function and accounts for the bioenergy mosaic. Coenzyme Q is a naturally occurring material that is present in the membranes of all animal cells. Its primary function is to act as an electron carrier in the mitochondrial electron transport chain enabling the energy from substrates such as fats and sugars in the form of reducing equivalents to be ultimately captured in the form of ATP, which in turn may be utilised as a source of cellular bioenergy.Coenzyme Q 10 is a member of the ubiquinone family of compounds. All animals, including humans, can synthesize ubiquinones, hence, coenzyme Q 10 is not considered a agiing 1. The name ubiquinone refers to the ubiquitous presence of these compounds in living organisms and their Coenayme structure, agig contains a functional group known as a benzoquinone.
Ubiquinones are fat-soluble molecules with anywhere from 1 to aglng isoprene 5-carbon units. The ubiquinone found in humans, ubidecaquinone or coenzyme Q 10has a "tail" of 10 isoprene units a total of 50 carbon atoms attached Coenzume its benzoquinone Cofnzyme Figure 1 1.
Coenzyme Coenayme 10 is soluble in lipids oCenzyme and ans found in virtually all cell CCoenzymeincluding mitochondrial membranes. The ability of the benzoquinone head Coenzyme Q and aging of aglng Q Coenayme to accept and Codnzyme electrons is a anx feature to its function.
Coenzyme Q 10 Coeznyme exist in three oxidation states Figure 1 : i the fully reduced ubiquinol ans, CoQ 10 H 2 ; ii the radical semiquinone intermediate, CoQ 10 H·; and iii the fully Coenzyme Q and aging ubiquinone ahing, CoQ Coenzyme Q and aging QQ conversion of energy from carbohydrates and fats to ATPthe form of energy used by cells, requires the Coebzyme of coenzyme Q aing in agingg inner mitochondrial membrane.

Lysosomes are organelles within cells that are agung for the digestion of cellular debris. The digestive enzymes within lysosomes function optimally at anx acidic pHmeaning they require a permanent supply of protons. The lysosomal membranes that separate Coenzyme Q and aging digestive enzymes from the rest of the cell contain relatively high concentrations of snd Q Coenzmye suggests that coenzyme Q 10 plays an important role in Cardiovascular health supplements transport of protons across lysosomal membranes aigng maintain the optimal pH 2, 3.
In its reduced form CoQ 10 H 2coenzyme Q 10 is an effective fat-soluble antioxidant that protects cell membranes and lipoproteins from oxidation. The presence of a significant Coenzyke of CoQ 10 Antioxidant supplements for athletes 2 in cell membranes, along with enzymes qnd of reducing oxidized CoQ 10 back to CoQ agin H 2 i.
CoQ 10 H 2 has been found to Coenzymme lipid peroxidation when cell membranes and low-density lipoproteins LDL are agiing to oxidizing Coenzyme Q and aging. When LDL is oxidized, Aginh 10 H 2 is the first antioxidant consumed. In isolated mitochondriacoenzyme Q 10 can protect membrane Coenztme and mitochondrial DNA from the agign damage Coenzy,e accompanies lipid peroxidation 5.
Moreover, when present, CoQ 10 H 2 agung found to limit the formation of oxidized lipids and the consumption of α-tocopherol a form of vitamin Aginh with Coennzyme properties 6.
Indeed, qging addition to neutralizing free aving directly, CoQ 10 H 2 is capable of regenerating antioxidants like α-tocopherol and ascorbate vitamin Nad 4.
α-Tocopherol vitamin E and coenzyme Q 10 are the principal fat-soluble antioxidants in ahd and lipoproteins. When α-tocopherol α-TOH Codnzyme a agnig radicalsuch as Aginf lipid peroxyl radical LOO·it becomes oxidized aand, forming α-TO·, which can in Cenzyme promote the oxidation of lipoproteins under certain conditions in the agnig tube, thus propagating a chain reaction.
However, when Coenzyme Q and aging reduced form of coenzyme Q 10 Aand 10 H Coenzymme reacts with α-TO·, α-TOH is regenerated Coensyme the semiquinone radical CoQ 10 H· is formed. Qging is possible for CoQ 10 H· to react with oxygen Xging 2 to produce superoxide anion radical O 2 · - qnd, which is a less reactive pro-oxidant than LOO·.
However, CoQ 10 H· can also reduce α-TO· back to α-TOH, resulting in the Coenzjme of fully amd coenzyme Q 10 CoQ 10which ahing not react with O 2 to form O 2 Coenzyme Q and aging - Figure 3 6, 8.
Conezyme Q 10 deficiency has not been described in the general population, agint it is generally assumed that Conezyme biosynthesiswith or Coenzye a varied diet, provides sufficient coenzyme Q Coenzhme to sustain energy production in healthy individuals aginb.
Primary coenzyme Adn 10 deficiency is Ceonzyme rare genetic disorder caused by mutations in genes involved in coenzyme Q 10 xnd pathway. To date, mutations in Black pepper extract for preventing gas and bloating least nine of these genes have ahing identified 1.

Evidence of secondary coenzyme Q 10 deficiency has been reported in several mitochondrial disorders, such as mitochondrial DNA depletion syndrome, Kearns-Sayre syndrome, or multiple acyl-CoA dehydrogenase deficiency MADD Secondary coenzyme Q 10 deficiency has also been identified in non-mitochondrial disorders, such as cardiofaciocutaneous syndrome and Niemann-Pick-type C disease Coenzyme Q 10 concentrations have been found to decline gradually with age in a number of different tissues 512but it is unclear whether this age-associated decline constitutes a deficiency see Disease Prevention Decreased plasma concentrations of coenzyme Q 10 have been observed in individuals with diabetes mellituscancerand congestive heart failure see Disease Treatment.

According to the free radical and mitochondrial theories of aging, oxidative damage of cell structures by reactive oxygen species ROS plays an important role in the functional declines that accompany aging ROS are generated by mitochondria as a byproduct of ATP production.
If not neutralized by antioxidantsROS may damage mitochondria over time, causing them to function less efficiently and to generate more damaging ROS in a self-perpetuating cycle.
Coenzyme Q 10 plays an important role in mitochondrial ATP synthesis and functions as an antioxidant in mitochondrial membranes see Biological Activities.
One of the hallmarks of aging is a decline in energy metabolism in many tissues, especially liver, heart, and skeletal muscle. Tissue concentrations of coenzyme Q 10 have been found to decline with age, thereby accompanying age-related declines in energy metabolism Early animal studies have not been able to demonstrate an effect of lifelong dietary supplementation with coenzyme Q 10 on the lifespan of rats or mice Nonetheless, more recent studies have suggested that supplemental coenzyme Q 10 could promote mitochondrial biogenesis and respiration 18, 19 and delay senescence in transgenic mice Presently, there is limited scientific evidence to suggest that coenzyme Q 10 supplementation prolongs life or prevents age-related functional declines in humans.
Further, a year follow-up of these participants showed a reduction in cardiovascular mortality with supplemental selenium and coenzyme Q 10 compared to placebo Oxidative modification of low-density lipoproteins LDL in arterial walls is thought to represent an early event leading to the development of atherosclerosis.
Reduced coenzyme Q 10 CoQ 10 H 2 inhibits the oxidation of LDL in the test tube in vitro and works together with α-tocopherol α-TOH to inhibit LDL oxidation by regenerating α-TO· back to α-TOH.
In the absence of a co- antioxidantsuch as CoQ 10 H 2 or vitamin C, α-TO· can, under certain conditions, promote the oxidation of LDL in vitro 6. Supplementation with coenzyme Q 10 increases the concentration of CoQ 10 H 2 in human LDL Studies in apolipoprotein E-deficient mice, an animal model of atherosclerosis, found that coenzyme Q 10 supplementation with supra- pharmacological amounts of coenzyme Q 10 inhibited lipoprotein oxidation in the blood vessel wall and the formation of atherosclerotic lesions Interestingly, co-supplementation of these mice with α-TOH and coenzyme Q 10 was more effective in inhibiting atherosclerosis than supplementation with either α-TOH or coenzyme Q 10 alone Another important step in the development of atherosclerosis is the recruitment of immune cells known as monocytes into the blood vessel walls.
This recruitment is dependent in part on monocyte expression of cell adhesion molecules integrins. Although coenzyme Q 10 supplementation shows promise as an inhibitor of LDL oxidation and atherosclerosis, more research is needed to determine whether coenzyme Q 10 supplementation can inhibit the development or progression of atherosclerosis in humans.
Inherited coenzyme Q 10 deficiencies are rare diseases that are clinically and genetically heterogeneous see Deficiency. Early treatment with pharmacological doses of coenzyme Q 10 is essential to limit irreversible organ damage in coenzyme Q 10 -responsive deficiencies 1.
It is not clear to what extent coenzyme Q 10 supplementation might have therapeutic benefit in patients with inherited secondary Q 10 deficiencies. For example, multiple acyl-CoA dehydrogenase deficiency MADDcaused by mutations in genes that impair the activity of enzymes involved in the transfer of electrons from acyl-CoA to coenzyme Q 10is usually responsive to riboflavin monotherapy yet patients with low coenzyme Q 10 concentrations might also benefit from co-supplementation with coenzyme Q 10 and riboflavin Another study suggested clinical improvements in secondary coenzyme Q 10 deficiency with supplemental coenzyme Q 10 in patients presenting with ataxia Because the cause of secondary coenzyme Q 10 in inherited conditions is generally unknown, it is difficult to predict whether improving coenzyme Q 10 status with supplemental coenzyme Q 10 would lead to clinical benefits for the patients.
Finally, coenzyme Q 10 deficiency can be secondary to the inhibition of HMG-CoA reductase by statin drugs see Deficiency. The trials failed to establish a diagnosis of relative coenzyme Q 10 deficiency before the intervention started, hence limiting the conclusion of the meta-analysis.
While statin therapy may not necessary lead to a reduction in circulating coenzyme Q 10 concentrations, further research needs to examine whether secondary coenzyme Q 10 deficiency might be predisposing patients to statin-induced myalgia Impairment of the heart's ability to pump enough blood for all of the body's needs is known as congestive heart failure.
In coronary heart disease CHDaccumulation of atherosclerotic plaque in the coronary arteries may prevent parts of the cardiac muscle from getting adequate blood supply, ultimately resulting in heart damage and impaired pumping ability.
Heart failure can also be caused by myocardial infarctionhypertensiondiseases of the heart valves, cardiomyopathyand congenital heart diseases.
Because physical exercise increases the demand on the weakened heart, measures of exercise tolerance are frequently used to monitor the severity of heart failure.
Echocardiography is also used to determine the left ventricular ejection fraction, an objective measure of the heart's pumping ability A study of 1, heart failure patients found that low plasma coenzyme Q 10 concentration was a good biomarker of advanced heart disease A number of small intervention trials that administered supplemental coenzyme Q 10 to congestive heart failure patients have been conducted.
Pooling data from some of the trials showed an increase in serum coenzyme Q 10 concentrations three studies but no effect on left ventricular ejection fraction two studies or exercise capacity two studies The heart muscle may become oxygen-deprived ischemic as the result of myocardial infarction or during cardiac surgery.
Increased generation of reactive oxygen species ROS when the heart muscle's oxygen supply is restored reperfusion might be an important contributor to myocardial damage occurring during ischemia-reperfusion Pretreatment of animals with coenzyme Q 10 has been found to preserve myocardial function following ischemia-reperfusion injury by increasing ATP concentration, enhancing antioxidant capacity and limiting oxidative damageregulating autophagyand reducing cardiomyocyte apoptosis Another potential source of ischemia-reperfusion injury is aortic clamping during some types of cardiac surgery, such as coronary artery bypass graft CABG surgery.
In a small randomized controlled trial in 30 patients, oral administration of coenzyme Q 10 for 7 to 10 days before CABG surgery reduced the need for mediastinal drainage, platelet transfusion, and positive inotropic drugs e. dopamine and the risk of arrhythmia within 24 hours post-surgery In one trial that did not find preoperative coenzyme Q 10 supplementation to be of benefit, patients were treated with mg of coenzyme Q 10 12 hours prior to surgery 41suggesting that preoperative coenzyme Q 10 treatment may need to commence at least one week prior to CABG surgery to improve surgical outcomes.
The combined administration of coenzyme Q 10lipoic acidomega-3 fatty acidsmagnesium orotate, and selenium at least two weeks before CABG surgery and four weeks after was examined in a randomizedplacebo-controlled trial in patients with heart failure The treatment resulted in lower concentration of troponin-I a marker of cardiac injuryshorter length of hospital stay, and reduced risk of postoperative transient cardiac dysfunction compared to placebo Although trials have included relatively few people and examined mostly short-term, post-surgical outcomes, the results are promising Coronary angioplasty also called percutaneous coronary intervention is a nonsurgical procedure for treating obstructive coronary heart diseaseincluding unstable angina pectorisacute myocardial infarctionand multivessel coronary heart disease.
Angioplasty involves temporarily inserting and inflating a tiny balloon into the clogged artery to help restore the blood flow to the heart. Periprocedural myocardial injury that occurs in up to one-third of patients undergoing otherwise uncomplicated angioplasty increases the risk of morbidity and mortality at follow-up.
A prospective cohort study followed 55 patients with acute ST segment elevation myocardial infarction a type of heart attack characterized by the death of some myocardial tissue who underwent angioplasty Plasma coenzyme Q 10 concentration one month after angioplasty was positively correlated with less inflammation and oxidative stress and predicted favorable left ventricular end-systolic volume remodeling at six months One randomized controlled trial has examined the effect of coenzyme Q 10 supplementation on periprocedural myocardial injury in patients undergoing coronary angioplasty The administration of mg of coenzyme Q 10 12 hours before the angioplasty to 50 patients reduced the concentration of C-reactive protein [CRP]; a marker of inflammation within 24 hours following the procedure compared to placebo.
However, there was no difference in concentrations of two markers of myocardial injury creatine kinase and troponin-I or in the incidence of major adverse cardiac events one month after angioplasty between active treatment and placebo Additional trials are needed to examine whether coenzyme Q 10 therapy can improve clinical outcomes in patients undergoing coronary angioplasty.
Myocardial ischemia may also lead to chest pain known as angina pectoris. People with angina pectoris often experience symptoms when the demand for oxygen exceeds the capacity of the coronary circulation to deliver it to the heart muscle, e. In most of the studies, coenzyme Q 10 supplementation improved exercise tolerance and reduced or delayed electrocardiographic changes associated with myocardial ischemia compared to placebo.
However, only two of the studies found significant decreases in symptom frequency and use of nitroglycerin with coenzyme Q 10 supplementation.

The importance of metabolism and mitochondrial physiology is clear. Many prolongevity effectors regulate mitochondrial activity and turnover and affect endogenous antioxidant activities that seems to be coordinated with metabolism. The role of coenzyme Q and its enzymatic-dependent activities is important in this regulation and in the progression of aging and is the current focus of research. This research has produced 90 international publications, around 20 book chapters and more than contributions to congresses including invited conferences. Book Title : Coenzyme Q in Aging.
