The label looks different compared to the previous ones I got, is it still the same OPTIMUM NUTRITION product?

As you evolve, so do we. The part of our mission is to help active individuals better understand OPTIMUM NUTRITION products. Now choosing the right product for you is easier with more visible product benefits, features and flavours on each tub.

Has Gold Standard 100% Casein formula been improved?

Our latest formula is now fortified with zinc which contributes to a healthy immune system and magnesium to support normal protein synthesis. Source: Official Journal of the European Union - COMMISSION REGULATION (EU) No 432/2012

The tub is not full to the brim when opened, why is that?

This is completely normal and is to do with the way the powder is vacuum packed into the tub. The powder settles over time. This does not impact the weight or number of servings listed on the label.

Are the ingredients tested and safe?

All of the ingredients in our products have been approved and considered safe for consumption by the European Food Safety Authority.
