In addition to vitamins and minerals, trace elements also play a crucial role in boosting metabolism. Trace elements are essentially minerals , but we only need them in small amounts, just traces . Usually, less than 50 mg per kg of body mass is sufficient to meet our needs.
If they are supplied to the body in insufficient quantities, a deficiency occurs. Therefore, even if only minute amounts are required, they should not be disregarded. The so-called NRVs, or Nutritional Reference Values, also provide a guideline here. They indicate the proportion of the average daily requirement for vitamins and minerals.
A typical characteristic of trace elements is that they are found in various sources , not just food. Some trace elements are present in soil, rocks, or water.
Trace elements are fundamentally classified as essential or non-essential . This means that the body urgently needs some of them, while it can easily do without others. They are therefore not vital for the body.
