Get a second opinion on non-toxic products and the claims made about them. This puts my product analysis in your hands. Tell the Second Opinion widget what you own or are considering, and it'll run it through Interior Medicine's methodology the same way I'd review it myself: what's in it, what reaches you, and how to reduce that.

Or, check an alarming study using the same steps I use, to see what it actually means and whether it applies to your life.

Version 3 is brand new. Leave feedback below to shape Version 4.

This is the practical outcome of the What Does "Non-Toxic" Mean? course. The product checker runs on the six-step toxicology framework from the course, applied through the Material Health Guides: separating hazard from risk, and factoring in your real-life exposure, dose, and susceptibility.

The research checker uses the same approach the course teaches in Part 3: how to read a toxicity study and tell what it actually shows.

If you want the full methodology, the methodology page is the quick reference; the course teaches it in full.
