The Science

Most collagen never gets absorbed. Ours is made to be.

In 2025, the University of Milan independently tested our tripeptide collagen. It showed up to 5x more biological activity than standard collagen.

Why ours is different

It comes down to size.

Ordinary collagen pieces are too big, so your body breaks them down like any food. Ours are small enough to be absorbed intact.

Relative sizes shown for comparison, not to molecular scale. Da = Daltons, the unit scientists use to weigh molecules.

Independently tested

Tested by university scientists, not by us.

Pharmaceutical scientists checked more than what is in it. They tested what it actually does.

How they tested it

Three kinds of testing most collagen never goes through.

Golden linked molecules suspended in a glass vessel

By computer

Every piece mapped

Modelled how active each collagen piece is likely to be.

A gloved hand pipetting a sample into a laboratory test plate

In the lab

Enzyme tests

Measured how it interacts with the body's own enzymes.

In human gut cells

Where absorption happens

Checked it stays active in the cells that take it in.

The headline finding

Up to 5x more active than standard collagen.

What this means for youMore of what you take each day is put to use, not just digested.

Laboratory peptide modelling, University of Milan, 2025. Not a clinical outcome.

What the testing found

More than skin deep.

Works with your appetite

Worked with the body's natural fullness signals at a normal daily serve.

Supports healthy circulation

Interacted with the body's own systems for healthy blood flow.

Stays active where it counts

Remained active in human gut cells, right where absorption happens.

Gentle enough for every day

Testing confirmed it is well tolerated, made for a long-term routine.

Precision, not commodity

A bioactive collagen, not just another protein powder.

Laboratory models evaluate biological behaviour under controlled conditions and do not represent a claim of clinical outcomes.

Why it matters as we age

Your body makes less collagen every year.
