This page is where our testing and sourcing information lives. We would rather show you an honest gap than imply a standard we have not met.
Where our products are made
Our formulas are manufactured in the United States by a white-label supplier and shipped from their fulfilment centre.
Certificates of analysis
When a batch has a certificate of analysis, we link it directly on that product's page under "Lab results (COA)". If there is no link on a product page, that batch does not have one yet. We will not describe a product as "third-party tested" without a document behind it.
How we decide what a label can say
Every structure/function claim we publish is backed by human clinical evidence kept on file, recorded with the dose and form used in the trial and the population studied. A claim only ships if the evidence matches the product we actually sell. Where trials used a higher dose than our serving, or were run in people who already had a condition, we soften the claim or drop it.
What we are still working on
- Publishing certificates of analysis for every batch.
- Full quantitative supplement facts panels for the multi-ingredient formulas.
If you want the evidence behind a specific claim, email us and we will send you the citations.
