CAPMAG® ZN

As an essential trace mineral, zinc plays a crucial role in many biological processes and is essential for the proper physiological functioning of animals. However, its absorption is relatively low (around 20%) due to the presence of anti-nutritional compounds such as phytic acid (phytate) in the diet. These molecules form insoluble and non-absorbable complexes with free Zn²⁺  ions in the digestive tract, which hinders the absorption of zinc. Zinc cannot be absorbed, so it is excreted in the faeces and can accumulate in the soil, harm microorganisms, plants and contaminate water.

CAPMAG® Zn’s effectiveness lies in the protection of zinc by magnesium, which optimizes the solubilization kinetics of the trace element. Thanks to this technology, the release of zinc is gradual and maximum in the last phase of the stomach. This delayed solubilization avoids the formation of complexes between zinc and anti-nutritional factors such as phytates, making it impossible to cover the requirements optimally. Numerous in vitro and in vivo  tests have made it possible to validate the concept.
