Lab results

First-party testing is run in-house by the company that makes a product. Third-party testing is run by an independent, accredited laboratory with no stake in the outcome, so the product is checked impartially rather than the brand grading its own work. Every lot is third-party tested before release, and a green Third-party badge marks the lots whose independent certificate is already posted above.

An independent lab has no incentive to pass a batch, so its certificate is real proof rather than a promise. It confirms the label is accurate and screens for contaminants you cannot see or taste. It is the standard we hold ourselves to and the one worth looking for in any electrolyte mix.

Three things: label accuracy, where the sodium, potassium, magnesium, chloride, and vitamin C are measured against what the package claims; heavy metals (arsenic, cadmium, lead, and mercury) screened against safety limits; and microbial safety (E. coli, Salmonella, total plate count, and yeast and mold).

A COA is the laboratory report for a single production lot. It lists every test, the measured result for that lot, and the limit it must meet, so you can confirm exactly what is in the product you bought.

Find the lot number printed on your jar or packet, then search it in the box above or filter by flavor. Each certificate lists the lot it covers.
