why take collagen peptides？

As a brand owner, the simple answer is: because that’s exactly what consumers are demanding right now.
People take them primarily for two massive markets: “Beauty from Within” (improving skin elasticity, reducing wrinkles, and strengthening hair/nails) and Healthy Aging/Joint Support. We’ve also seen a massive spike in our sports nutrition line, as athletes take them to support tendon and ligament recovery after heavy workouts. If you don’t have a collagen SKU in your brand lineup right now, you are leaving money on the table.
