Yonder Collagen is Certified Glyphosate Residue-Free by The Detox Project
Yonder Grass-Fed Collagen Peptides are certified Glyphosate Residue-Free by The Detox Project. That means our finished product is independently lab-tested and shown to carry no detectable glyphosate residue down to a strict limit. For a collagen you may stir into your coffee every single morning, that kind of verified purity is the whole point of Yonder.
What is glyphosate, and why does it matter in collagen?
Glyphosate is the most widely used agricultural herbicide in the world. The World Health Organization's International Agency for Research on Cancer (IARC) has classified it as a probable human carcinogen, which is why many people choose to limit their exposure where they can.

Collagen peptides are made from the hides and connective tissue of cattle, so the cleanliness of the finished powder traces directly back to how those animals were raised and fed. When cattle are finished on grain, that grain is often grown with glyphosate, and residues can carry through into collagen made from it. This is why grass-fed alone is not enough. What you want is grass-fed and grass-finished, pasture-raised cattle, so there is no grain-feed pathway to begin with. Yonder is sourced from 100% grass-fed and grass-finished, pasture-raised cattle.
How the Glyphosate Residue-Free certification works
The Glyphosate Residue-Free certification, administered by The Detox Project, is one of the few truly independent, third-party purity standards in this category. To carry it, a product has to be tested at an ISO 17025 accredited laboratory using LC-MS/MS, one of the most sensitive testing methods available, and it checks the finished product, not just the ingredients.
It screens for two things, not one:
- Glyphosate itself, and
- AMPA, glyphosate's primary breakdown product. A product can read low on glyphosate but still show its metabolite, so a serious test screens for both.
To qualify, the finished product must show no residue down to roughly 10 parts per billion (0.01 ppm), and certified products are re-tested on an ongoing basis. Yonder verifies its finished product through Light Labs, an ISO 17025 accredited laboratory, to exactly this standard. You can confirm our certification directly on The Detox Project's public Certified Products directory.
The bigger picture: glyphosate is everywhere
The concern is not abstract. A widely cited study found glyphosate in the urine of roughly 93% of Americans tested, and average levels rose substantially between the 1990s and the 2010s. For something measured at that scale in the food supply, choosing a collagen that has actually been tested, rather than one that simply calls itself clean, makes a real difference.
Look for the Glyphosate Residue-Free seal
A brand can call itself clean, natural, or pure without ever running a single glyphosate test. A real Glyphosate Residue-Free claim is backed by an accredited lab, an ongoing certification, and a public listing you can verify. When you shop for collagen, look for this seal, and confirm the brand is on The Detox Project's certified-products list:
Purity does not stop at glyphosate. Yonder is also third-party tested for heavy metals (lead, cadmium, arsenic, and mercury), made from a single ingredient with no fillers or sweeteners, and held to and beyond California's strict Prop 65 standard.
Our latest lab results
Transparency is the whole point of a certification, so here are the actual numbers. Our flavorless collagen (Lot 418957) was tested by Light Labs, an independent ISO 17025 accredited laboratory in Ann Arbor, Michigan, for glyphosate and its breakdown product AMPA, and for heavy metals. Results below.
Glyphosate and AMPA (LC-MS/MS)
| Analyte | Result | Detection limit |
|---|---|---|
| Glyphosate | None detected | 10.13 ppb |
| AMPA (glyphosate breakdown product) | None detected | 10.13 ppb |
No glyphosate and no AMPA were detected down to the laboratory limit. This is the finished-product testing behind our Glyphosate Residue-Free certification.
Heavy metals (ICP-MS/MS)
| Analyte | Result |
|---|---|
| Lead | None detected |
| Cadmium | None detected |
| Mercury | None detected |
| Arsenic | Below the detection limit |
Tested 2025-11-05 by Light Labs (Lev Spivak-Birndorf, Lab Director). Results relate to the lot tested, and we test on an ongoing basis.

A note from our founders
"We have always believed that what is NOT in your collagen matters as much as what is. We test every batch and got Yonder certified Glyphosate Residue-Free because it is the standard we wanted for our own families. We hope every clean brand follows."
Sheri and Gina, Founders of Yonder
Why we built Yonder this way
We did not set out to start a supplement company. We set out to find a collagen clean enough for our own families, and we could not. So we built it. Yonder is certified Glyphosate Residue-Free by The Detox Project, grass-fed and grass-finished, single ingredient, and third-party tested for purity. One to two scoops gives you 10 to 20g of collagen, plus 9 to 18g of clean grass-fed protein as a bonus, flavorless and easy to stir into anything.
