Along with iodine, selenium plays an important part in the manufacture of thyroid hormone (it is involved in converting the inactive precursor into the active hormone) and also possesses high anti-oxidative potential. The soil in Europe is low in both selenium and iodine. Very soluble salts such as those in trace element tablets do not have to compete with other substances for uptake in the colon. They can even be made insoluble by certain substances (e.g. Vitamin C) and metallic selenium can be produced as a result of reduction, so it is unwise to take these simultaneously.


is present in over 300 different enzyme systems, and hence involved in numerous basic life processes. It plays a central part in protein and nucleic acid metabolism (necessary for protein utilisation) and is involved in the manufacture of thyroid hormone, insulin and prostaglandin (anti-inflammatory agent) and as such, responsible for growth and a healthy immune system. Its uptake by the body takes place through active transport mechanisms where it competes with other minerals such as calcium or phosphate, phytic acid and its salts. It is advisable to take it at a different time to other food or mineral preparations.


Trivalent chrome forms part of the glucose tolerance factor, which has a decisive role in the metabolism of glucose and sugars. It is also a cofactor for certain enzymes important in fat metabolism. Heavy physical work and certain situations (e.g. disturbances in sugar metabolism, pregnancy) cause larger amounts to be used up. Certain food elements (so-called phytates, for example, found in significant amounts in soya) restrict its uptake, others, such as vitamin C, encourage it.
