Collagen protein powder

Collagen protein, typically sold as collagen peptides, comes from animal connective tissue and has a different amino acid profile than whey, casein, or most plant proteins — notably lower in some essential amino acids, which is why it is not usually described as a complete protein in the same sense as those alternatives. It is often chosen for its neutral taste and ability to dissolve in hot and cold liquids without a distinct protein-shake flavor. This page includes products identified primarily as collagen peptides, so you can compare total protein per 25 grams across brands. Because collagen has a different amino acid composition than other protein types, comparing it directly to whey or plant protein on a gram-for-gram basis does not capture that difference; check the ingredient list for sourcing (such as bovine or marine) if that matters to your choice.
