We would rather show you than ask you to trust us. The certificate of analysis for every product is posted here and linked from each product page, so you can read the same lab report we do.

What we test. Every batch is verified against its label before it ships. Each certificate lists the electrolyte amounts, a heavy-metals screen (arsenic, cadmium, lead, mercury), and microbial safety (E. coli, salmonella, plate count, yeast and mold).

How it is tested. Our flavored lots are tested by an independent lab. Our unflavored lots are verified against label specs by the manufacturer, with independent third-party confirmation in progress. Each certificate states its testing source plainly.

How it stays current. These files are pulled straight from each product, so when a new lot is tested, its certificate replaces the old one on its own. What you see here is always the latest.
