From an R&D and formulation perspective, the main reason we use collagen peptides (specifically hydrolyzed collagen) rather than regular collagen or gelatin is bioavailability.
Because the amino acid chains are broken down into much smaller molecular weights, they are easily absorbed into the bloodstream. But honestly, the biggest reason I love working with them is that high-quality peptides are highly soluble in cold water and have a completely neutral taste and odor. This makes them perfect for formulating everything from clear RTD (ready-to-drink) beverages to flavorless stir-in powders.
