How Codex curates products
Every product passes three checks before it reaches you.

We surface brands operators and coaches are already buying — never paid placement.
Wellness review
Each SKU is scored against our charter: ingredient quality, evidence, claims, sourcing.
Operator-tested
Coaches and studios in our network try it on real clients before we recommend it.

A look inside the Codex vetting process, where we separate the genuinely useful from the merely novel in the world of wellness tech, coaching, and studios.
Vetted under the Codex charter
We only stock products that pass our ingredient, evidence and sourcing review. If a SKU stops meeting the bar, it's delisted — full stop.
