How to Compare Protein & Peptide Ingredients

Product names alone are not enough for procurement. Buyers should confirm source, protein content, peptide content, molecular weight, allergen status and finished supplement format before ordering.

Protein Content

For plant proteins and collagen powders, protein percentage is one of the first parameters to confirm by COA.

Peptide Content

For hydrolyzed peptides and oligopeptides, peptide content and hydrolysis level should be checked by batch.

Molecular Weight

Average molecular weight helps buyers compare collagen peptides, tripeptides and oligopeptide powders.

Allergen Status

Fish, shellfish, wheat, tree nut, animal-derived and plant-derived source declarations should be confirmed before import.
