As founders, we create ONA with the same care we expect for our own families. That's why ONA Gut & Glow is independently third-party tested by an ISO 17025 accredited lab for heavy metals and microbial safety, to help ensure quality and consistency. We believe you should know exactly what's in your daily ritual, because trust should be earned, not assumed.

Our products are manufactured in a cGMP (current Good Manufacturing Practice) facility with globally sourced ingredients.

Who tests it

ONA Gut & Glow is tested by Twin Arbor Analytical, an independent laboratory in San Luis Obispo, California.

What we test for

Testing is done on the finished product, so all our ingredients are included in it. Our recent lab reports cover:

• Microbial safety. Salmonella, E. coli, Staphylococcus aureus, Clostridium, yeast and mold.
• Heavy metals. Lead, arsenic, cadmium and mercury.

Recent results

Microbial panel. Orange flavor, lot 260515, reported July 2026. Salmonella, E. coli, Staphylococcus aureus and Clostridium: absent. Yeast, mold and Enterobacteriaceae: below 100 CFU/g.

Heavy metals panel. Reported January 2026 on an earlier batch. Cadmium and mercury: not detected. Arsenic: 0.034 ppm. Lead: 0.014 ppm.

"Absent" and "not detected" mean the lab looked for it and found none. "ppm" means parts per million.
