Microplastics
Our longest-running program. We track the exposure literature, publish a quarterly reading digest, and formulate around binders and fibre inputs that our customers ask about most.

Cleaner inputs. Clearer information.
PTX Labs develops supplements and publishes plain-language resources on environmental exposure. Our active programs focus on two areas people ask us about most: microplastics and immune system support.

Why this matters
The exposure picture, in published numbers
Figures below are drawn from peer-reviewed literature and public agency reporting. They describe the environment we all live in — they are not claims about any product.

Three things, done carefully
We are a small team. We would rather run two programs properly than ten loosely.
Immune system support
Foundational nutrients — vitamin D3, zinc, selenium and mushroom extracts — at transparent doses, alongside resources on what the research does and does not currently show.
Testing & documentation
Every batch goes to an independent ISO 17025 laboratory for identity, potency and contaminant screening. Certificates of analysis are published by lot number, not on request.
Our standard
If we cannot document it, we do not print it
The supplement category has a credibility problem, and most of it is self-inflicted. We took the opposite approach: publish the boring paperwork, describe ingredients by what they are rather than by what they promise, and let people draw their own conclusions.
- Full-disclosure labels — no proprietary blends, every input listed at its actual dose
- Independent lab results published per lot, including the ones we would rather not show
- Sourcing country and supplier audit status listed for each raw material
- Plain-English summaries of the studies we cite, including their limitations
