WE GROW IT. YOU MAKE IT YOURS.
GRIBB BULK
Behind every great mushroom product is an ingredient worth believing in.
At GRIBB, we cultivate functional mushrooms at our own farm in Portugal and transform them into concentrated extracts designed for the next generation of wellness, supplement and functional food brands.
Whether you're launching your first mushroom supplement, expanding an existing range or looking for a more transparent ingredient partner, we're here to supply the mushrooms behind your products.
Grown by us. Branded by you.
the opportunity
We don't just source mushrooms. We grow them.
There's a big difference between knowing where an ingredient comes from and simply trusting what a supplier tells you.
The functional mushroom industry is full of complicated supply chains, anonymous manufacturing and ingredients that change hands several times before reaching the brands that sell them.
We chose a different approach.
why gribb
What no other functional mushroom brand on your shelf can say.
GRIBB was founded around a simple idea: if we're going to put our name behind a mushroom, we want to know everything about it.
That's why we grow our own functional mushrooms in Portimão, Portugal, using certified organic cultivation practices, and oversee their journey from cultivation to extraction.
We work directly with brands that want to bring functional mushrooms to market without compromising on provenance, ingredient integrity or transparency.
We believe the brands of tomorrow deserve to know exactly what's inside their products — and who's behind them.
Your brand stays yours
We supply the ingredient. You create the product experience. Our extracts can be used in your own formulations or packed and marketed under your brand, subject to applicable food and supplement regulations.
Farm-grown, farm-controlled
We cultivate our own functional mushrooms at our farm in the Algarve, giving us direct oversight of the growing environment, harvesting and raw materials that enter our production process.
PT-BIO-10 certified organic
Certified by NATURALFA under Portugal's organic standard. Covers the full production chain — substrate, cultivation, harvest, extraction, bottling. Not a label. An audit.
Quality you can trace
Our ingredients are backed by documented production processes, batch traceability and laboratory quality testing. Technical specifications and relevant documentation are available to support your product development and quality reviews.
We grow the mushrooms. You grow your brand.
You don't need to own a mushroom farm to build a mushroom brand.
That's where we come in.
GRIBB supplies concentrated functional mushroom extracts and selected formulations in bulk to businesses developing, manufacturing or commercialising products under their own labels.
From single-species powders to complex functional blends, we provide an ingredient supply solution rooted in cultivation, extraction expertise and transparent production.
Our role is simple: to make the ingredient side of your business more reliable, more traceable and a lot less complicated.

BUILT FOR YOUR BRAND
Your label. Your identity. Our ingredients.
We know how much work goes into building a brand.
The positioning. The packaging. The customer experience. The trust.
We also know that behind all of that is something even more important: the quality and consistency of the ingredients you choose.
GRIBB Bulk is designed for businesses that want to remain independent while working with a producer that understands functional mushrooms from the ground up.
We're not a faceless ingredient marketplace.
SMALL ENOUGH TO KNOW YOU. SERIOUS ABOUT WHAT WE GROW.
GRIBB is an independent, family-run mushroom business based in Portugal.
We grow, produce and work closely with the ingredients we supply, which means when you speak to us, you're speaking directly to the people behind the mushrooms.
We understand the challenges of bringing a product to market because we've done it ourselves — from creating formulations and managing production to packaging, regulations and building a brand from scratch.
That's the kind of experience we bring to a bulk partnership.
Not just a catalogue of powders.
A real connection to the source.
