Increased oxidative damage in the lungs and poor antioxidant protection, including low levels of CoQ10, can result in lung diseases, such as chronic obstructive pulmonary disease COPD and asthma.

Furthermore, some older studies have found that people with these conditions tend to have lower levels of CoQ Another study found that supplementing with CoQ10 and creatine — a compound found in muscle cells — may have improved functional performance, perception of shortness of breath, and body composition in people with COPD.

CoQ10 could reduce oxidative damage in the lungs, which may benefit respiratory conditions like asthma or COPD. Current studies note that either ubiquinol or ubiquinone is acceptable for use as a supplement. No significant difference between the two was found in regards to absorption.

CoQ10 supplements are available in various doses, ranging from 30 to mg. Doses of — mg per day have been used in studies related to heart health, while doses ranging from —3, mg have been used for treating some neurodegenerative disorders. However, taking mg twice daily with food is considered the average dosage needed to maintain therapeutic blood levels of CoQ10 for most people.

Because CoQ10 is a fat-soluble compound, its absorption is slow and limited. However, taking CoQ10 supplements with food can help your body absorb it better than taking it without food. Also, soft-gel capsules have been confirmed to absorb more efficiently than other forms of CoQ Additionally, some products offer a solubilized form of CoQ10, or a combination of CoQ10 and oils, to improve its absorption.

CoQ10 is well-tolerated and is not associated with any serious side effects. The following foods contain CoQ10 :. In addition to the foods listed above, some types of fruits, vegetables, dairy products, and cereals also contain CoQ10, though in much lower amounts.

CoQ10 is found in many food sources, including meat, fish, poultry, legumes, nuts, seeds, and oils. Supplementing with CoQ10 appears to be well tolerated by humans, even when used in doses up to 1, mg. You may experience some insomnia or indigestion, and you should not take it if you are also taking blood thinning medications like Warfarin Jantoven and certain cancer medications.

CoQ10 may reduce the effectiveness of warfarin Jantoven , as well as interact with some blood pressure and cancer medications. In particular, research suggests that it may help improve heart health and blood sugar regulation, protect against certain types of cancer, and reduce the frequency of migraine.

It may also reduce oxidative damage that leads to muscle fatigue, skin damage, and brain and lung diseases. However, more research is necessary to determine whether CoQ10 can help in these areas. CoQ10 can be found as a supplement that seems well tolerated, but you should ask your doctor before trying it.

In fact, CoQ is made of benzoquinone moiety and an isoprenoid side chain the length of which is 10 units both in man and many mammals; therefore we talk about CoQ 10 and reduced CoQ 10 ubiquinol Other living organisms possess different species of CoQ, for instance Saccharomyces cerevisiae produces CoQ 6 , other microorganisms CoQ 7 , and many mammals CoQ 9.

Each organism possesses a dominant homolog of CoQ, and minor amounts of other homologs. Most of CoQ 10 available as a food supplement is natural CoQ 10 , extracted from some microorganisms which synthesize CoQ 10 , identical to the one which is found in humans and other mammals.

This issue will be commented later on in the text. For a certain number of years CoQ was known for its key role in mitochondrial bioenergetics; later studies demonstrated its presence in other subcellular fractions and in plasma, and extensively investigated its antioxidant role. The rationale supporting the use of CoQ 10 as a food supplement is mainly based on these two functions.

More recent data reveal that CoQ 10 affects the expression of genes involved in human cell signalling, metabolism and transport Groneberg et al. New progress has been made in elucidating CoQ 10 in metabolism and nutrition. This short chapter is mainly focused on recent findings which will hopefully contribute to better understand the relationship between basic biochemical mechanisms and certain physiological and clinical effects.

The essential role of CoQ 10 in bioenergetics was postulated since the years of its discovery. In fact several years later, the studies of Nobel Prize winner Peter Mitchell highlighted the central role of this quinone in the chemo-osmotic production of ATP.

Therefore CoQ 10 is a key component of the mitochondrial machinery, the main energy plant of our cells. If mitochondria are devoid of CoQ 10 they cannot produce ATP; in some conditions we can have partial CoQ 10 deficiencies.

Even though the concentration of CoQ 10 in mitochondria is rather high compared to the corresponding concentration of other mitochondrial components, it is not saturating. This practically means that at the actual concentrations of CoQ 10 in these membranes the velocity of the respiratory complexes is not the maximal one.

In fact, small variations in the concentration of CoQ 10 in these membranes leads to remarkable changes in the respiratory rates of these cells.

This can explain why, even though a small part of the exogenously administered CoQ 10 is uptaken by our cells, the effect is not negligible figure 1.

Figure 1. FEBS Lett ; : Strictly speaking CoQ 10 is not a vitamin, as mammals and lower animals are capable of synthesizing this molecule. A minor part is however introduced through the diet; moreover a series of dietary components is essential for the proper functioning of CoQ 10 biosynthesis figure 2.

Figure 2. Coenzyme Q 10 content of different foods Source: Kamei et al. The Distribution and Content of Ubiquinone in Foods. Internat J Vit Nutr Res ; The synthesis of the quinone moiety of CoQ 10 starts from phenylalanine or from tyrosine and the isoprenoid side chain derives from mevalonate.

A series of vitamin cofactors is needed for this biosynthesis. According to Karl Folkers the dominant source of CoQ 10 in man is biosynthesis. This complex, 17 step process, requiring at least seven vitamins vitamin B2 — riboflavin, vitamin B3 — niacinamide, vitamin B6, folic acid, vitamin B12, vitamin C, and pantothenic acid and several trace elements, is, by its nature, highly vulnerable.

Karl Folkers argues that suboptimal nutrient intake in man is highly possible and that there is subsequent secondary impairment in CoQ 10 biosynthesis. It was highlighted that in a vitamin B6 deficiency plasma CoQ 10 levels are also low and they increase upon improvement of the vitamin B6 deficiency status Willis et al.

In eukaryotes the isoprenoid side chain of coenzyme Q is synthesized through the mevalonate pathway, which also leads to the synthesis of cholesterol. As we will comment below statins, the potent and widely used anticholesterolemic drugs, also inhibit CoQ 10 biosynthesis and this could have important practical implications.

Coenzyme Q 10 concentration greatly varies in different tissues, probably related to different metabolic demands figure 3. Figure 3. Concentration of coenzymeQ 10 in different human tissues Source: Okamoto T, et al.

Internat J Vit Nutr Res 59; ; Aberg et al. Archives of Biochemistry and Biophysics and Biophysics ; ; Shindo Y, et al. J Invets Dermatol ; Tissue concentrations of CoQ 10 also vary with age: for different organs an increase of CoQ 10 has been found in the initial decades with a subsequent decrease figure 4.

Figure 4. The concentration of coenzyme Q 10 in the body decreases year by year, indicating that it has a close relationship with aging Kalen A, et al. Lipids ; In its reduced form ubiquinol coenzyme Q acts as a phenolic antioxidant, undergoing hydrogen abstraction by free radicals, therefore it acts like a chain breaking antioxidant.

This evidence has been produced by numerous experimental models, both in vivo and in vitro, using artificial membranes, isolated subcellular organelles, cultured cells, isolated perfused organs and clinical models Dallner and Stocker, Reduced Coenzyme Q is also able to regenerate α-tocopherol, the active form of Vitamin E: in this sense CoQ 10 and vitamin E are considered as a lipophilic antioxidant duo of primary importance.

In order to act as an antioxidant CoQ must be in the reduced state; several enzymes exert this function of CoQ reductases. There are some conditions where the reducing capacity of the cell might be impaired: in these conditions supplementing CoQ 10 already in the reduced state QH 2 , ubiquinol might be particularly relevant.

It is currently believed that high levels of LDL, as well as smoking and hypertension, are primary risk factors, among those contributing to cardiovascular disease. Biochemical mechanisms responsible for the atherogenicity of LDL have been extensively addressed, and experimental evidence bas been produced indicating that oxidatively modified LDL become atherogenic.

It was found that endothelial cells are involved in the oxidative attack against LDL. Oxidative attack on LDL deeply affects the apoprotein moiety as well.

LDL leave the blood stream, penetrate the endothelial cell lining and reach the subendothelial space, where they undergo oxidative attack. Oxidatively modified LDL are capable of triggering further events, including platelet activation, and exert a chemotactic attraction on circulating monocytes, which migrate to the subendothelial space, where they become macrophages.

As discussed above, oxidatively modified LDL are easily recognized by the scavenger receptors. These events lead to an accumulation of lipids, mainly cholesterol and cholesterol esters, in the macrophages, which will become lipid-laden foam cells.

Foam cells may be considered the essence of the atheromatous lesions. LDL are endowed with a number of lipid soluble antioxidants capable of preventing or minimizing lipid peroxidation.

Plasma levels of CoQ 10 have been extensive investigated Tomasetti et al. Most plasma CoQ 10 is transported by LDL where, together with vitamin E, it exerts its antioxidant protection. Ubiquinol is the most reactive antioxidant in LDL, and although it is present at lower concentrations compared to vitamin E, it is able to regenerate α-tocopherol from the tocopheril radical, making the vitamin E-ubiquinol duo the most important antioxidant system in LDL.

CoQ 10 enriched LDL, isolated from plasma of healthy volunteers orally treated with CoQ 10 for a few days, were less susceptible to peroxidizability in vitro, compared to the same LDL in basal conditions Mohr et al. Blood CoQ 10 is mainly transported by LDL, although it is also present in the other classes of lipoproteins and in blood cells.

But it is worthwhile to normalize these values according to the blood LDL content or at least to plasma cholesterol levels. Besides decreasing LDL peroxidizability, CoQ 10 could have a direct antiatherosclerotic effect, in fact animal studies have shown that CoQ 10 administration attenuates aortic atherosclerotic lesions Witting et al.

CoQ 10 is commonly assayed in plasma, both in basal conditions and after oral supplementation. Basal CoQ 10 levels might reflect CoQ 10 deficiency and, as pointed out above, they might have a predictive value in cardiac failure. Post supplementation levels of CoQ 10 are also important, since a clinical response is much more common if some threshold values are reached.

Several studies have highlighted that a plasma level of at least 2. Of course quantification of plasma CoQ 10 is also important to assess bioavailability of different CoQ 10 formulations. Methods are usually based on HPLC separation: a simple, yet precise and accurate method is the one which appears in the website of the International CoQ 10 Association Littarru et al.

Coenzyme Q 10 can also be quantitatively assayed in cells and in biological fluids. These are conditions where, due to genetic reasons one or more of the steps involved in CoQ 10 biosynthesis are impaired.

In some cases there is a dramatic positive response to exogenous CoQ 10 administration Quinzii et al. Some analytical problems have been found in the quantification of CoQ 10 and other CoQs in vegetable oils and generally in fatty samples, due to interferences mainly with triacylglycerides.

A clean, efficient separation and quantification procedure was recently proposed and applied to the determination of CoQ 9 and CoQ 10 contents in different vegetable oil samples Rodriguez-Acuna et al. The key role of coenzyme Q 10 in mitochondrial bioenergetics has suggested its use in an attempt to improve aerobic capacity and physical performance.

Some studies have highlighted an ergogenic effect while others did not. These issues have recently been addressed in 3 papers published in Cooke et al.

One of these articles shows that following a single administration of CoQ 10 plasma levels significantly correlated with muscle CoQ 10 levels, maximal oxygen consumption and treadmill time to exhaustion. In another trial, oral administration of CoQ 10 improved subjective fatigue sensation and physical performance Mizuno et al.

The third article is a double blind study where a group of kendo athletes showed lower levels of CK, myoglobin and lipid peroxides compared to the corresponding values in the placebo group Kon et al.

Coenzyme Benefifs COQ10 is an essential element for Coenzhme Coenzyme Q benefits functions. As an benefitd that protects B vitamins and depression from the effects of Coenzymme, CoQ10 Coezyme been used in medical Coenzyme Q benefits for decades, especially for treating Coenzyme Q benefits problems. Although we create some of our own coenzyme Q10, there are still advantages to consuming more, and lack of CoQ10 is associated with damaging effects of oxidative stress. CoQ10 deficiency is thought to be linked with conditions such as diabetes, cancer, fibromyalgia, heart disease and cognitive decline. The name may not sound very natural, but coenzyme Q10 is in fact an essential nutrient that works like an antioxidant in the body. Coenzyme Q benefits
