Why are the micronutrients that we eat not always the micronutrients that we use?
Many micronutrients are transformed or broken down once we eat them. Some food have other substances added to the micro so that they can be used to carry out their proper function. For vitamins, most of the transformations activate them. As for minerals, they are not changed, but there might be minor changes made to their structure.
