We often receive enquiries about the compatibility and combinability of individual ingredients in our ESN products when different products are combined.

For example, there is a belief that magnesium and calcium interfere with each other's absorption.

This is not the case with our carefully formulated products. First of all, it is important to mention that the studies that have observed inhibited absorption in combination have been carried out with abstractly high dosages, in test tubes or in animal models. This does not reflect the way our products are used.

In nature, micronutrients almost always occur in combination.

When selecting the individual vitamin and mineral compounds, great care was taken to ensure that they do not interfere with each other's absorption. For example, zinc, iron and copper are present as bisyglycinates, which do not have a negative effect on each other. Magnesium and calcium are also not inhibited in the doses in which they are used in the Athlete Stack. In physiological dosages, which we recommend in our products (see the product-specific consumption recommendation), the combination is not a problem.

Minerals and vitamins also occur together in food. Such competition may apply to extremely high dosages. Of course, we would never recommend this. Therefore, please always observe the recommended intake. These competing effects have not been proven to be significant in humans.
