Seven answers, one score per product, four picks with the reasoning shown.
The quiz scores every product in the catalog against your answers and shows you the four that score highest, with the reason each one made the list.
Answer seven questions.
What you want to support, how you want to feel through the day, what you already take and how you prefer to take things. No account, no email required to see the result.
Every product is scored against your answers.
The quiz works from the same product facts as the site: the benefit each formula is built for, its form, its standardization and what it pairs with. Our team tunes the scoring from what customers report back.
Read the reason, then read the research.
Each pick comes with a sentence on why it matched and a link to that product's research snapshot, the published studies behind the formula, reviewed by our Scientific Advisory Board.

A recommendation is only as good as the testing behind the bottle.
The quiz can only point you at products we would stand behind in a lab. Here is what stands behind every one of them.
Standardized to the compounds the research used
Many of our formulas are built around a specific bioactive, from erinacine A to crocins and safranals, measured by our own analytical lab rather than a generic marker.
Why ND?Every batch third-party tested
Identity, purity and potency are tested at an ISO/IEC 17025 accredited laboratory, and the certificate of analysis is published by lot number on the product page.
Trust Through TransparencyClaims reviewed by an independent board
A physician, a plant biologist, an ethnobotanist and a nutrition scientist check every benefit claim against the cited studies before it goes on a page.

Every product page carries its research snapshot and its certificate of analysis, so you can check a pick before you buy it.
