Although depression can have many different causes, new research suggests that CoQ10 supplementation may help alleviate symptoms when used alongside standard treatment. This is highlighted in a recent meta-analysis published in the Journal of Clinical Psychopharmacology. The authors describe how CoQ10 plays a dual role: it is essential for cellular energy production and also functions as a powerful antioxidant that protects nerve cells and other tissues from damage caused by oxidative stress. It is important to choose a CoQ10 supplement of documented quality with high bioavailability.

The production of cellular energy takes place in the mitochondria, where Q10 plays a key role in the metabolism of the two primary fuels: carbohydrates and fats, which are broken down into blood sugar and fatty acids. In addition, cellular uptake of blood sugar requires chromium, and mitochondrial uptake of fatty acids requires a substance called carnitine. Meat and other animal products naturally contain carnitine and therefore support efficient fat metabolism. The body can also produce small amounts of carnitine, a process that requires vitamin C.
You can also read about a Danish-Norwegian study that revealed how mice must consume six times more calories to gain one gram of body weight when fats are combined with a high protein intake. By contrast, fats combined with carbohydrates result in poor energy utilization, with a risk of excess fat storage and increasing overweight.

Cholesterol-lowering statins, which are among the most widely used medications, not only reduce cholesterol levels but also decrease the body’s synthesis of Q10, a compound that is important for energy metabolism and serves as a key antioxidant. Reduced endogenous Q10 synthesis may lead to various side effects, including muscle pain. However, a Pakistani observational study published in Cureus suggests that Q10 supplementation may reduce muscle pain in patients taking cholesterol-lowering statins. Overall, it appears that Q10 supplementation may help reduce several side effects associated with statin use.

Q10 is a unique molecule that is involved both in the cells’ energy metabolism and in protecting cells against damage caused by oxidative stress. This means that the busy brain and vulnerable nerve cells require a fair amount of Q10. However, the body’s own synthesis of Q10 gradually declines with age and with the intake of cholesterol-lowering statins. According to a review article published in Nutrients, Q10 supplementation appears to improve brain health and cognitive abilities. One should choose pharmaceutical-grade Q10 supplements to ensure good bioavailability, so that the Q10 molecules reach the brain and other organs.

Q10 is a coenzyme of crucial importance to cellular energy metabolism. It also functions as a powerful antioxidant that protects cells against damage caused by free radicals. It’s a fact that cells use more energy during physical activity, and for that reason the impact of free radicals increases. Evidence suggests that supplementation with Q10 in connection with exercise may support energy metabolism, improve performance, and help prevent damage to muscles and other tissues. This is highlighted in a review article published in Archives of Physiology and Biochemistry.

- including serious complications?

Older adults are more easily infected with influenza, COVID-19, and other infections and are also at greater risk that these infections will develop into complications such as pneumonia or acute respiratory distress syndrome (ARDS), which can be potentially life-threatening. One major reason is chronic “inflammaging” caused by widespread deficiencies of vitamin D, vitamin C, selenium, zinc, omega-3 fatty acids, and Q10. This not only increases the risk of infection but also the risk that the immune system will overreact with hyperinflammation, which is the real reason why respiratory infections and sepsis can become life-threatening. Overall, it appears that aging processes increase the need for specific nutrients, and if the immune system is well supplied, it will usually handle most pathogens without causing any symptoms.
