Want to improve your skin condition, support your bone and joints or lose weight? It is then important to understand the background knowledge. You may have heard about protein, peptide, collagen, and gelatin before, but do you know the difference between them and how they work?

Protein:

It’s a macromolecule linked by different acid amino. The protein is the most common element and the basic molecular unit of every living creature.

Peptide:

A peptide is an amino acid polymer that is composed of amino acids. The number of amino acids should be under dozens when we define a simple peptide. When the number of amino acid that the polymer holds becomes great than twenty, we call it polypeptide. In summary, a peptide is a middle unit between protein and amino acid.

Collagen:

Collagen is one of the most important protein in the human body. Full-length collagen cannot be directly absorbed by the human body as an oral supplement. Macromolecular collagen can be broken down to form collagen peptides or gelatin.

Gelatin:

It’s a partially hydrolyzed macromolecule of collagen.

To sum up, all are made up with same amino-acids, but choose collagen peptides over collagen for the most beneficial supplement.
