These are food supplements aimed to provide the necessary minerals and vitamins to compensate for natural deficiencies in food. Other additives may also be incorporated in order to influence the characteristics of food or animal production.

The premixes that contain mineral micronutrients and vitamins are microcorrectors and can also incorporate production stimulators, antioxidants, binding agents, aromas, pigments, amino acids, coccidiostats, etc.

These supplements are marketed under the generic name of “NUTRIDEX”.

When the premix is intended to satisfy the animals’ needs in terms of calcium, phosphorus and salt, we obtain a macrocorrector which we call “MACRODEX”.

In the design of DEX premixes, a fundamental objective is present: EFFICIENCY.



To fulfil this objective, DEX IBÉRICA meticulously selects active components, paying special attention to the concepts of STABILITY and COMPATIBILITY. Indeed, choosing coated formats (thermostabilisers), suitable salts, mildly acidic substances, etc., as well as strict quality control ensure compliance with these specifications.

Aside from the active ingredients described in the catalogue, the premix formula also includes food additives, diluents and technological coadjuvants which don’t change the nutritional value of the mix but are essential in guaranteeing quality. It is worth pointing out the humectants and anti-humectants, pH regulators, antioxidants and synergistic agents, anti-sticking agents, etc.

THE CARRIER must always be stable, non-hygroscopic, compatible, free from electrostatic effects, etc., and entails a painstaking study given that the success or failure of the corrector depends on choosing the proper carrier.


NUTRIDEX premixes use excipients with a high load capacity to ensure transport without the segregation of active components.

In MACRODEX premixes, the carrier is fundamentally selected according to the granulometry of the feed it is intended for in order to achieve maximum diffusion.

In the ELABORATION of premixes, special attention is given to technological means as well as the production protocol. Therefore, in order to ensure proper distribution of ingredients (some of which are present in very small quantities), precision in the weight and homogeneity of the mix must be continuously checked.

It is also important to follow operational methods that protect the most labile ingredients, preventing their contact with moisture, light, mineral catalysers, etc.
