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.

Chronic fatigue is quite common, and it is not simply a matter of too little sleep and too much work. Japanese researchers have found that low levels of vitamin B12 and folate (vitamin B9) may contribute to increasing fatigue and lack of motivation in otherwise healthy individuals. The Japanese study was published in the journal Nutrients.

Patients with multiple sclerosis have lower blood levels of vitamin D compared with healthy individuals. In addition, higher-dose vitamin D supplementation is associated with a reduced risk of relapses, which are new neurological symptoms or flare-ups of previous symptoms, according to a meta-analysis published in Frontiers in Immunology. Strong summer sunlight is the primary source of vitamin D, and multiple sclerosis is more common in Nordic countries and populations with limited sun exposure. There is also no guarantee that the official recommendations for vitamin D supplementation are sufficient to optimize blood levels.

The incidence of breast cancer has been rising in recent years. Diet, lifestyle, and genetic predisposition all play a role. There is also evidence that the trace element selenium helps protect against cancer, including breast cancer, through several mechanisms. According to a Polish population study published in the International Journal of Molecular Sciences, this appears to apply even among the many women with breast cancer who have high levels of the genotype HRG (histidine-rich glycoprotein).

Liver cirrhosis can lead to serious long-term complications. Common causes include nutrient deficiencies, excessive alcohol consumption, and chronic liver inflammation. Many people also have the precursor condition known as non-alcoholic fatty liver disease (NAFLD), often without being aware of it.
A meta-analysis published in BMC Nutrition shows that zinc supplementation improves liver function across several parameters in patients with cirrhosis.

Pregnant women are advised to take folic acid (vitamin B9) and vitamin D to support fetal growth and neurological development. However, fish oil has received less attention, despite its content of the omega-3 fatty acids EPA and DHA, which play a crucial role in the development of the brain, vision, and numerous metabolic functions.
New evidence now suggests that supplementation with fish oil alongside the recommended prenatal vitamins may reduce the risk of preterm birth and low birth weight. These findings come from a study published in Frontiers in Nutrition. In addition, fatty fish and fish oil supplements appear to offer other benefits for maternal mood and fetal health.

Patients with colorectal cancer often have vitamin D deficiency and chronic inflammation. These are factors that not only increase the risk of developing the disease but also worsen prognosis. However, higher-dose vitamin D supplementation appears to reduce a key inflammatory marker associated with disease progression and poor outcomes, according to a German randomized, double-blind, placebo-controlled study published in the British Journal of Cancer.

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.

Modern diets, soft drinks, candy, excessive alcohol intake, and obesity contribute to the fact that around one-third of the world’s population has developed fatty liver disease, often without realizing it. Over time, this increases their risk of liver inflammation, liver fibrosis (scar tissue), cirrhosis, primary liver cancer, and cardiovascular disease. It is well known that treating fatty liver disease requires dietary changes, although the results are often inadequate. According to a study published in Metabolism, vitamin B3 appears to have a therapeutic effect by influencing a genetic factor involved in the liver’s fat metabolism.
