Process for producing mineral substance preparations with multiple components that contain a low level of or no contaminants wherein material of plant or animal origin is used and at least two different thermo-oxidative treatment steps in separate locations are carried out. Mineral substance preparations produced according to the invention are characterized in that they basically contain the mineral substances that the respective plant absorbs from the ground in a highly bio-available form, at the same time have a very low content of thermally-modified organic compounds. Not easily dissolvable a priori trace elements are therefore preferably in colloidal form, which is why biologic absorption is especially high. The effect of these mineral substance preparations on health and fitness are by far superior than the currently available mineral substance preparations, since they also all contain trace elements that can no longer be analytically verified but can nevertheless have a considerably energizing effect on the human body.
