Before getting into the benefits of their collagen, itâs important to understand the difference between Vital Proteinâs Collagen Peptides and Vital Proteinâs Collagen Protein (gelatin).

The main difference is use â the peptides dissolve instantly in hot or cold liquids without gelling for an easy nutrition boost. Beef Gelatin â (Green lid) Think gelatin. Remember, it has the same nutritional benefits of collagen peptides because it is the same amino acids. However, collagen protein can be used to make homemade jello or gummies because it gels.
