In your protein products you use sucralose (E 955) in the puddings and acesulfame K and cyclamate in the low-fat quark products. Would it be possible to use aspartame instead? This is because aspartame is processed into phenylalanine, which in turn boosts the utilization of proteins. This would make the products more effective and you could even advertise with them. For example, with the sentence "Increases the body's ability to absorb protein" (I'm not an advertising expert, but just something like that). As I often consume these products myself, I would be very happy about this.
