Unfortunately there is no information. I haven't found any for pre either. Presumably it is dosed in the same quantity as the normal Aptamil.

According to the manufacturer's website, it is level 5.

I have entered the following.
1. Europe
2. aptamil
3. Pronutra +DHA

Then at the bottom of the list under PRE it says Stage5
and the last product picture should be that of the milk powder.

Here you can enter the barcode of the powder. The setting should then be displayed.

Step 5: You can scan the QR code on the packaging at babybrezza.de.
