Why do you use so little calcium?

To determine the amount of calcium we need to add to our composition, we use FEDIAF and NRC guidelines. Thanks to the quality ingredients we use, some of the calcium (and most of the phosphorus) is already provided naturally. The residual value that we have to add is then extracted from purified minerals that are highly absorbable, as proven by our clinical tests. As a result, we end up having to add little calcium.
