Get a second opinion on just how non-toxic any home product is.

This product checker is the outcome of the What Does “Non-Toxic” Mean? course. Built on the six-step toxicology framework and on my Material Health Guides, it separates hazard from risk, and factors in your real-life exposure, dose, and susceptibility.

It's in beta, so expect some bugs. Try it out and let me know what you think. Feedback enters you in the Course Giveaway, running through June 8th. The entry form is below the checker. Enjoy!
