Verification

Checked by people who do not work here.

Glucoraphanin content moves with cultivar, light and harvest day. That is exactly why our own number is not enough. Independent analysis and research partners sit between our claim and your formulation.

01

What gets checked,
and by whom.

Every lot carries an analysis. Some tests run per batch, others per season or per cultivar trial.

Who we work with.

Four Dutch institutions, each on a different part of the question. Status is shown as it stands, not as we would like it to be.

Brightlands Campus Greenport Venlo

Applied research and pilot infrastructure
Status to confirm

Pilot facilities and analytical capacity in the same region as the greenhouse, used for trial batches and method development before a protocol goes to full scale.

Venlo, LimburgTrials and methods

HAS green academy

Cultivation and harvest research
Status to confirm

Applied work on substrate, sowing density and harvest window, including the trials that set our day nine cut and the move from cellulose to hemp mat.

Den Bosch and VenloCultivation protocol

Wageningen University & Research

Glucosinolate science
Status to confirm

Cultivar and light spectrum work on glucosinolate formation, and the reference expertise behind how we read and report a glucoraphanin figure.

WageningenCompound and cultivar

Maastricht University

Human nutrition
Status to confirm

Nutrition research capacity for the question a supplement brand eventually has to answer, which is what actually reaches the bloodstream and in what form.

MaastrichtAbsorption and effect

Naming a research institution is a claim about them as well as about us. Each entry above is published only with that party's agreement, and describes work that is contracted or under way. Nothing here should be read as an endorsement of a finished product.

Analytical values describe the lot tested. Glucoraphanin content varies with cultivar, light recipe, harvest day and storage, and is confirmed per batch. Photon Farm supplies an ingredient and analytical data. Health claims on a finished product are the responsibility of the party placing that product on the market, under Regulation EC 1924/2006.
