The energy contained within the egg supports embryo growth for the first 7 — 10 days of life, from the moment of fertilization through implantation. This energy drives embryo development, including the normal replication of chromosomes that results in a healthy baby.
The research on CoQ10 and fertility suggests supplementation leads to more successful pregnancies. CoQ10 plays a critical role in energy production within the cells, yet the natural presence of CoQ10 in the body decreases after age Research shows CoQ10 supplementation has a positive impact on pregnancy success, especially in women over the age of Taking extra CoQ10 is particularly helpful in situations where the quality of the eggs may already be compromised, including:.
While our bodies do make CoQ10, natural production decreases with age. Supplements were prepared in tablet form and packaged in generic bottles for double blind administration by Pharma Base, S.
Supplementation compliance was monitored by having the subjects return empty bottles of the supplement at the end of 14 days of supplementation. Prior to each testing session, subjects were instructed to record all food and fluid intake over a 4-day period, which was reflective of their normal dietary intake and to include one weekend day.
Dietary inventories were then reviewed by a registered dietician and analyzed for average energy and macronutrient intake using the ESHA Food Processor Version 8. Subjects were required to fast for 12 hrs prior to donating approximately four teaspoons 20 milliliters of venous blood from an antecubital vein using standard phlebotomy procedures. Blood analyzed for CoQ10 was placed in a test tube containing heparin as the anticoagulant and immediately centrifuged at g using a standard bench top centrifuge Cole Palmer, Vernon Hills, IL, Model for 15 minutes at room temperature.
Blood analyzed for makers of oxidative stress and clinical chemistry panels were placed into two serum separation tubes and immediately centrifuged at g for 15 min. Whole blood was only analyzed pre- and post-exercise. This analyzer has been known to be highly valid and reliable in previously published reports [ 28 ]. Each serum sample was assayed for a standard complete metabolic panel [ glucose, aspartate aminotransferase AST , alanine aminotransferase ALT , alkaline phosphatase ALP , albumin, globulin, sodium, chloride, calcium, carbon dioxide, total bilirubin ], lipid panel [ triglycerides, total cholesterol, high-density lipoprotein HDL , low-density lipoprotein LDL , total cholesterol:HDL ] and clinical markers of protein and fatty acid metabolism [ uric acid, creatinine, blood urea nitrogen BUN , BUN:creatinine ratio, total protein, creatine kinase CK , ketones betahydroxybutyrate , and lactate dehydrogenase LDH ].
Enzyme immunoassay EIA was used to measure serum 8-Isoprostane. Serum concentrations were determined using a Wallac-Victor IV Perkin-Elmer Life Sciences, Boston, MA micro plate reader at an optical density of nm against a known standard curve using standard procedures. Fine Needle Aspiration FNA muscle biopsies were taken on days 0 and 14 prior to, and following performance tests in order to examine total CoQ10 content in the muscle according to standard procedures [ 29 ].
Participants were instructed to refrain from exercise 48 h prior to each muscle biopsy. Briefly, 0. The biopsy needle was placed into the biopsy device and the inserted into the previously made pilot hole a depth of about 5—10 mm.
A muscle sample was obtained by the activation of a trigger button, which unloaded the spring and activated the needle to collect a muscle piece. This whole biopsy procedure was repeated two to three times in order to obtain sufficient muscle tissue 15—30 mg. Total CoQ10 was determined by summing the oxidized and reduced forms.
Delta scores post minus pre values were calculated for each exercise test Isokinetic, Wingate, Cardiopulmonary and analyzed using repeated measures ANOVA. Pearson product correlations were used to determine any relationship between criterion variables and an alpha level of 0. No adverse events were reported concerning the supplementation or study protocol. No reports of medical problems or side effects were indicated in post-study questionnaires administered in a blinded manner.
Complete blood counts with platelet differentials were run on all whole blood samples and a standard clinical safety panels was completed on all serum samples at baseline, day 0 and day Therefore, these data are not reported. It should be noted that triglyceride levels were below the normal range in both groups and such a decrease observed in the supplement group could primarily be due to normal physiological variation.
No other statistically significant interactions were observed across groups. No significant differences were observed between groups in changes in total body water, bone mass, lean body mass, or body fat percentage over the course of the investigation. No statistically significant interactions were observed among groups in anaerobic capacity indices peak power, mean power, rate to fatigue, or total work.
No statistically significant interactions were observed across groups in other indices of aerobic capacity i. A significant main effect for time was observed in serum SOD levels, indicating an increase following all exercise performance measurements on day 0 T2 and day 14 T3.
No other significant interactions were observed. No other significant effects were observed. Time course of plasma CoQ10 concentration. No significant interactions were observed following chronic supplementation. Time course of muscle CoQ10 concentration. Following acute ingestion of CoQ10, plasma CoQ10 was significantly correlated to muscle CoQ10 levels; maximal oxygen consumption; and treadmill time to exhaustion.
The results from the present study demonstrate that a fast-melt form of CoQ10 is a safe and effective supplement that prolongs exercise performance in healthy individuals. Further, acute CoQ10 supplementation increased total CoQ10 concentration within the skeletal muscle and lowered plasma oxidative stress SOD during and following exercise. Though there is evidence in the literature to suggest a possible therapeutic role for CoQ10 in human diseases such as CHF, the potential ergogenic value in healthy trained and untrained individuals is less clear.
To our knowledge, this is the first study to demonstrate both improvements in exercise performance and increased muscle CoQ10 concentration in healthy trained and untrained humans following CoQ10 supplementation.
In the current study, both acute and chronic CoQ10 supplementation had no significant effect of indices of muscle endurance and anaerobic capacity as determined by an isokinetic repetition test and a second Wingate anaerobic capacity test.
Similarly, no significant differences were observed among groups in maximal oxygen uptake VO 2max or ventilatory anaerobic threshold following CoQ10 supplementation. Recently, Zhou and colleagues [ 3 ] investigated the effects of 4 weeks of CoQ10 supplementation on aerobic power, ventilatory threshold and exercise economy of healthy males.
Results showed no significant changes in aerobic performance VO 2max , ventilatory threshold or exercise economy in response to supplementation. Further, though CoQ10 concentration was elevated within the plasma, no significant increases were observed in the muscle.
Thus, the authors concluded that the lack of ergogenic benefit was likely due to an inability of supplementation protocol to increase CoQ10 concentration within the muscle [ 3 ]. Similar to Zhou and coworkers [ 3 ], results from the present study showed a significant increase in plasma CoQ10 concentration following chronic supplementation.
However, contrary to the observations of Zhou et al. In fact, muscle CoQ10 levels declined in the placebo group over the 2-week period. However, more research is needed before definitive conclusions can be drawn. Delta changes from baseline for muscle CoQ10 concentration. In the present study, the pre-supplementation concentration of muscle CoQ10 Conversely, Lamperti and colleagues [ 34 ] observed higher CoQ10 mean values of In the current study, muscle tissue was initially frozen and then subsequently analyzed 2—3 months following the final data collection.
This could explain the lower mean values observed in the present study compared to those reported by Lamperti et al. Approximately one half of CoQ10 in the body resides in the inner mitochondrial membrane [ 10 ].
CoQ10 is normally localized in the central hydrophobic portion of the membrane and thus, it has been suggested that its concentration may not be able to increase freely within the membrane due to physical limits and potential destabilization of the bilayer structure [ 35 ]. A number of human studies support this view that uptake of exogenous CoQ10 e. However, recent findings in young rodents argue against such a viewpoint, and suggest dietary supplementation with CoQ10 can lead to elevated CoQ10 levels within the mitochondria of the skeletal muscle [ 37 ].
One possible factor that may limit augmentation of CoQ10 in tissues in response to exogenous intake oral intake is duration. Although the dosage in the current study was similar to previous studies i.
In the current study, muscle CoQ10 concentration increased within about 2 hours of ingestion. It could be suggested that pharmacokinetics properties of CoQ10 uptake into the muscle is similar to that of creatine monohydrate. Such an effect could explain why previous studies have failed to show any increases in muscle CoQ10 concentration following 4—6 weeks of supplementation.
It is well established that CoQ10 is synthesized de novo in all tissues, and hence, under normal circumstances, most tissues are not dependent on an exogenous supply of CoQ However, under certain conditions such as oxidative stress and aging, endogenous production may not meet the demands for CoQ10 [ 39 ], and thus uptake may be increased.
This may suggest an enhanced uptake of exogenous CoQ10 from the plasma as a consequence of increased metabolism in active tissue. However, this will require further investigation. An alternative hypothesis is that since the new "fast-melt" CoQ10 formulation has demonstrated enhanced absorption kinetics into the blood stream compared to previous commercially available formulations [ 21 ], the increased bioavailability may enhance greater uptake into the muscle.
However, additional research will be needed to examine this hypothesis as well. Increased muscle CoQ10 concentration could explain the increased time to exhaustion observed in the current study. A week study in 50 people with diabetes found that those who received mg of CoQ10 per day had significant reductions in blood sugar, markers of oxidative stress and insulin resistance, compared to the control group Doses of — mg of CoQ10 per day appear to improve diabetes symptoms Oxidative damage is one of the main causes of both male and female infertility by negatively affecting sperm and egg quality 29 , For example, oxidative stress can cause damage to sperm DNA, potentially resulting in male infertility or recurrent pregnancy loss Research has found that dietary antioxidants — including CoQ10 — may help reduce oxidative stress and improve fertility in both men and women.
Supplementing with — mg per day of CoQ10 has been shown to improve sperm concentration, density and motility in men with infertility Similarly, these supplements may improve female fertility by stimulating ovarian response and help slow ovarian aging CoQ10 doses of — mg have been shown to help boost fertility CoQ10 supplements help reduce the inflammation associated with heavy exercise and may even speed recovery A 6-week study in German athletes found that those who supplemented with mg of CoQ10 daily experienced significant improvements in physical performance — measured as power output — compared to a placebo group CoQ10 has also been shown to reduce fatigue and increase muscle power in non-athletes Doses of mg per day appear to be most effective in boosting athletic performance in research studies Dosage recommendations for CoQ10 vary depending on individual needs and goals.
Speak with your doctor to determine the right dose for you. CoQ10 is generally well tolerated, even at extremely high doses of 1, mg per day or more However, some people who are sensitive to the compound may experience side effects, such as diarrhea, headache , nausea and skin rashes CoQ10 supplements can interact with some common medications, including blood thinners, antidepressants and chemotherapy drugs.
Consult your doctor before taking supplemental CoQ10 42 , Additionally, be sure to buy supplements that deliver CoQ10 in the form of ubiquinol, which is the most absorbable Though CoQ10 is generally well tolerated, some people may experience side effects like nausea, diarrhea and headaches, especially if taking high doses. The supplement may also interact with common medications, so speak to your doctor first. Coenzyme Q10 CoQ10 has been linked to improved aging, exercise performance, heart health, diabetes, fertility and migraines.
As with all nutrients or supplements, be sure to consult with your doctor, especially if you are taking medications, have health concerns, or are already pregnant. CoQ 10 is found in many different male and female fertility supplements. On supplement ingredient lists, CoQ10 is commonly found by the names ubiquinone and ubiquinol. Although the terms are sometimes used interchangeably, they are actually different forms of CoQ In the body, CoQ10 exists either in its oxidized form, ubiquinone, or in its reduced form, ubiquinol.
When oxidized CoQ10 ubiquinone is used by the body, it transforms and becomes ubiquinol. This process is very easily done when we are young but becomes more difficult as we age. The conversion process of ubiquinone to ubiquinol is complex and involves as many as five different enzymes. Recently, supplement brands have claimed that ubiquinol is a superior form of infertility supplement when compared to ubiquinone.
They claim ubiquinol has a higher absorbability and greater bio-availability. Some supplement brands will go as far as claiming that ubiquinol is eight times more absorbable than ubiquinone. Conclusive research does not exist supporting the efficacy of one form of CoQ10 over the other. Both ubiquinone and ubiquinol are fat-soluble and not very absorbable on their own. We know that by taking ubiquinol, our body can skip the extra step of converting CoQ10 ubiquinone into ubiquinol.
When choosing fertility supplements , you generally want to look for products that contain the most absorbable and bioavailable forms of each nutrient and well as products that combine key nutrients to provide a greater effect than any stand-alone nutrients. By increasing the absorption and bioavailability of ubiquinol, these supplements produce faster and better results. It is designed to provide men with all the essential nutrients they need to maximize their reproductive and overall fitness.
