Abbreviations on collagen packaging

For collagen, the number on the package most often describes the mass of a sachet, not the amount of collagen itself. These are two different values and are rarely equal.

A “10 g” sachet contains collagen peptides, but also flavouring, acid, sweetener and sometimes vitamin C and hyaluronic acid. The collagen content itself can therefore be several grams lower. Some manufacturers state it directly; for the rest, it must be found in the ingredients.

There is also the type and origin of the raw material — two pieces of information that marketing descriptions merge into one, although they describe entirely different things.

The terms one by one

Collagen peptidescollagen hydrolysate
Collagen broken down into shorter chains. This value, not serving mass, is comparable between products. If the manufacturer states only the mass of a sachet, there is nothing to compare and we mark it accordingly.
Type Icollagen of skin, bones and tendons
The most common type in supplements, obtained from bovine and fish skins.
Type IIcartilage collagen
Usually obtained from poultry cartilage; also sold in an undenatured form described as UC-II. It is not a substitute for type I.
Type IIIconnective-tissue collagen
It occurs together with type I and is usually not sold separately.
Marine collagenmarine origin
Alongside bovine and poultry collagen, one of the three typical sources. It is sometimes chosen for dietary reasons, not because of a difference in peptide content.
NatiCol, Peptan, Verisolraw-material trade names
Brands of collagen peptides by which manufacturers describe the origin of the raw material. The name alone does not state how many peptides are in a serving — that number must be found in the table. Watch for names such as “vegan collagen”: this is usually a mixture of free amino acids, not collagen peptides.
Daltonmolecular mass of peptides
A unit describing peptide size, stated as a number of daltons. Manufacturers use it as an argument, but it cannot be converted into the amount of collagen in a serving.
