wie viel eiweiß brauche ich — can a microbiome test help?

How much protein you need depends on age, weight, activity level, muscle mass, and health status. General guidelines (e.g., 0.8 g/kg body weight for adults, 1.2–2.0 g/kg for athletes) are based on decades of nutritional research. A microbiome test cannot directly determine your individual protein requirement. While gut bacteria do influence protein digestion and amino acid metabolism, the evidence linking specific microbial profiles to protein needs is still preliminary. Current stool tests measure bacterial diversity and abundance, but no validated biomarker exists to translate that into a personalized protein recommendation. The evidence is weak and mostly mechanistic. For optimizing protein intake, rely on established dietary guidelines and consult a nutrition professional – a microbiome test currently offers no reliable support for this question.
