What are essential trace elements?
An element is considered essential when a deficiency leads to a disruption of normal biological functions, which can be corrected by the intake of that specific element . Iron, zinc, copper, iodine, selenium, manganese and molybdenum are vital for humans. .
The specific roles of vital trace elements
Each trace element has a unique "fingerprint" in our biochemistry. For those seeking targeted support, it's valuable to understand its specific functions:
Zinc: The versatile supporter
Zinc is involved in the functioning of numerous enzymes in the body . It plays a role in various cellular processes, including cell division and protein synthesis . In addition, zinc supports the normal functioning of the immune system and contributes to healthy cognitive function. .
Iron: Transport and energy
Iron is best known for its role in the formation of hemoglobin, the substance in red blood cells that is involved in transporting oxygen throughout the body . This means it plays a direct role in energy metabolism and contributes to the reduction of fatigue. .
Selenium and Copper: Antioxidant Protection
Selenium and copper both function as important components of antioxidant enzymes . Selenium is also essential for normal thyroid function and supports the maintenance of healthy hair and nails. . Copper contributes to the maintenance of normal connective tissues and supports iron transfer in the body .
Iodine and Manganese: Regulation and Structure
Iodine is the primary building block for thyroid hormones, which are essential for regulating metabolism and growth . Manganese plays a role in the normal formation of connective tissue and supports energy levels by contributing to normal carbohydrate and fat metabolism .
The importance of homeostasis
In modern nutritional science we see that the balance between these elements – also called 'homeostasis' – is extremely important . A deficiency can arise from a one-sided diet, but also from an increased need of the organism in specific life phases .
At the same time, quality in supplementation is essential. Because the quantities are so small, precise dosing in accordance with scientific guidelines is important to respect the body's natural balance. .
Summary
Trace elements are essential micronutrients that, despite the minimal amounts in which they are needed, play a central role in our health. From zinc's support of cognitive function to iron's oxygen transport, these elements form the biochemical basis for a vital life. . A varied diet and, if necessary, targeted support helps maintain an optimal nutritional profile .
Frequently asked questions about trace elements
What's the difference between minerals and trace elements? Both are minerals, but the classification depends on the amount needed. We need macrominerals (such as calcium) in grams or hundreds of milligrams, while we only need micrograms or a few milligrams of trace elements .
Can the body produce trace elements itself? No, the body cannot synthesize trace elements itself. They must be obtained entirely from diet or supplemental sources .
Why are trace elements often called 'micronutrients'? This term refers to the fact that they are essential for physiological processes in very small (micro) quantities, unlike macronutrients such as fats and proteins .
