Depression is a growing global problem. The role of diet is often overlooked, and according to a large U.S. population study published in Frontiers in Nutrition, magnesium deficiency appears to increase the risk. The authors note that magnesium’s antidepressant effect is linked to multiple mechanisms that support the nervous system and mood. Magnesium is also important for digestion and gut microbiota, and disturbances in the gut-brain axis can contribute to depression-like conditions. Magnesium deficiency is widespread due to unbalanced diets and ultra-processed foods. In addition, stress, insulin resistance, excessive calcium intake, and certain medications can increase the body’s requirement for magnesium.

We are all exposed to mercury to varying degrees. Mercury is particularly damaging to the nervous system and make us more vulnerable to several diseases. Fetuses and small children are especially at risk, as mercury exposure can also cause lower IQ. A review published in Biology and Life Sciences Forum shows that selenium protects against mercury. However, this protection depends on a sufficient selenium intake, as this vital trace element is also required for vital body functions such as energy metabolism, thyroid function, immune defense, fertility, and much more.

Supplementing with fish oil has already shown therapeutic benefits in treating several skin conditions, including atopic eczema, acne, psoriasis, and even burns. Local treatment with fish oil may also be a useful complement, although more clinical studies are needed, according to a review published in the Journal of Cosmetic Dermatology. Since many skin disorders involve chronic inflammation, it is generally recommended to ensure fish oil is taken at a therapeutic dose. Fish oil also helps counteract dry skin, which is more vulnerable.

Autism is a complex disorder that occurs in varying degrees. It is believed to result from alterations in brain development. There are several contributory factors, including nutrient deficiencies and exposure to environmental toxins during pregnancy and early childhood. Blood samples from children with autism have revealed lower levels of selenium and zinc compared with healthy children, along with higher levels of aluminum - a metal regarded as a neurotoxin. This was demonstrated in a study published in Biological Trace Element Research. The combination of low levels of these two essential trace elements and widespread aluminum exposure may be a harmful mix that damages the brain and nervous system.

It is well known and widely recognized that COVID-19 vaccines in rare cases can cause an important complication called myocarditis, which is inflammation of the heart muscle. However, according to a study published in Frontiers in Immunology, vitamin D appears to play a protective role by regulating the immune system’s inflammatory reaction.

Vitamin C plays a role in connective tissue, the immune system, the brain, hormone balance, the circulatory system, and iron absorption. In addition, it functions as a unique antioxidant that protects cells and tissues from damage caused by oxidative stress. Official recommendations have primarily focused on preventing the classical deficiency disease scurvy, but evidence suggests that even mild deficiencies make the body more vulnerable. In a review article published in Molecules, the authors examined vitamin C’s therapeutic role in supporting quality of life and in the prevention of infections and various chronic diseases such as atherosclerosis, diabetes, and cancer.

There is good reason to believe so. According to a review article published in Clinical Nutrition ESPEN, fish oil supplements combined with strength training appear to improve muscle strength. The researchers therefore see potential in combining fish oil supplementation with strength training to enhance quality of life among elderly individuals. As an added benefit, fish oil may also have positive effects on circulation, joint pain, mood, and the preservation of cognitive abilities.

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.

Nutrients in the diet play an important role in energy levels and mental health. For example, chromium and selenium have a beneficial influence on blood sugar, the nervous system, and inflammatory processes, which are linked to fatigue, mood swings, psychiatric disorders, and poorer prognoses. This is highlighted in a review article published in the Journal of Clinical Psychopharmacology. According to the researchers, supplementation with chromium and selenium therefore has a potential role in the prevention and treatment of various mental disorders.
