Iron is essential for oxygen transport in the blood and cellular energy production, yet deficiencies are common in patients with chronic heart failure. This additionally impairs their physical capacity and quality of life. Iron deficiency is associated with hospitalization and early death, as highlighted in a review article published by the American College of Cardiology. Heart failure patients should therefore always have their iron status checked. Intravenous iron therapy appears to be most effective for treating iron deficiency in heart failure patients. It is also crucial for these patients to ensure adequate dietary iron intake while being mindful of factors that can limit iron absorption and utilization.

Our bodies naturally produce Q10, a compound with a crucial role in cellular energy metabolism that also functions as an antioxidant and protects against cell damage. Our natural production of Q10 declines significantly with age and as a result of various stress factors, thereby accelerating signs of aging. This also affects the condition of the skin. Research suggests that skincare products containing Q10 may slow down visible signs of aging, such as wrinkles and sagging skin. This is supported by a review article published in The Journal of Clinical Aesthetic Dermatology. Additionally, previous studies indicate that high-quality Q10 supplements may have potential benefits in counteracting various aging processes and the development of chronic diseases.

Calcium and magnesium are vital for our bones, nervous system, muscles, heart, blood pressure, and many other functions. It is essential to maintain the right balance between the two minerals that work in a team and can easily be compared to yin and yang. Vitamin D is also needed for the uptake and utilization of the minerals. Still, deficiencies of all three nutrients are widespread and that increases the risk of infections, neurological disturbances, muscle cramps, constipation, hypertension, osteoporosis, cancer, and a number of other grave diseases. In our part of the world, many people get too much calcium from dairy products and supplements. That can disrupt the delicate balance between calcium and magnesium and result in oxidative stress, chronic inflammation, and cell death.

Selenium deficiency is widespread in Europe and many other parts of the world, negatively impacting public health. On the other hand, adequate selenium intake through diet and supplements can reduce the risk of cardiovascular diseases, diabetes, metabolic disorders, cancer, and early death. A study published in Frontiers in Nutrition suggests that older individuals have an increased need for selenium.

Type 2 diabetes, a lifestyle disease that is spreading like wildfire, comes with a huge socio-economic price tag. At the same time, there has been a growing need for more effective and natural treatments for disrupted blood sugar levels, which cause a range of other metabolic disturbances. In addition to weight loss and dietary changes, it now appears that zinc supplementation can significantly improve various biomarkers related to disrupted blood sugar. This is outlined in a study published in Diabetology & Metabolic Syndrome.

Prostate cancer is widespread in the Western world. However, according to an American study published in the Journal of Clinical Oncology, dietary changes with more omega-3 fatty acids and fewer omega-6 fatty acids can reduce the development of prostate cancer cells after one year.

When cells convert the calories from food into energy, a variety of B vitamins, vitamin C, iron, magnesium, zinc, and Q10 are needed. This also means that a deficiency in one or more of these substances can result in mental and physical fatigue to a greater or lesser extent. The impaired energy metabolism of the cells also increases the risk of mood swings, concentration difficulty, infections, and other diseases. Modern lifestyle, ageing processes, medications, and other factors cause serious deficiencies, but these deficiencies can be corrected with help from dietary changes and relevant supplements.

Ageing, overweight, and respiratory infections can impair your sense of smell. However, a sufficiently high zinc intake from dietary sources or supplements can support or even improve the sense of smell – especially in older people and those who are overweight. This was shown in a study that is published in Rhinology. Unfortunately, zinc deficiencies are common due to poor diets and the use of various medical drugs that impair the body’s utilization of zinc.
