Les peptides de collagène peuvent-ils entraîner une prise de poids ?

The short answer is no. Pure collagen peptides are essentially just protein. From a macronutrient perspective, they contain zero carbohydrates, zero sugar, and zero fat. A standard 10-gram serving only contains about 35 to 40 calories. Unless your consumers are eating absurd amounts of it to the point of a massive caloric surplus, the pure raw material itself will absolutely not cause weight gain.
