Why does the Collagen Activator not dissolve 100%?

The Collagen Activator in its unique combination of ingredients will never be able to dissolve 100% and we are already working on an improved formulation.
The solubility will also improve with the new batch.
The fact that something settles when left to stand for a longer period of time is due to the properties of the ingredients - they simply cannot "dissolve" 100%.
As it also contains solids (algae powder as the basis for astaxanthin), it is more of a suspension.

We generally recommend dissolving it in lukewarm water or sparkling water, drinking it quickly and stirring it constantly. This also minimises the oxidation of the astaxanthin with the ambient air.
A drinking straw is a good way to minimise this and ensure that all the ingredients are well drunk.
We always endeavour to incorporate customer feedback into the formulations.
