We hold NSF Certified for Sport® and IHSA certifications, manufacture in accordance with Good Manufacturing Practices (GMP) standards, and partner with Light Labs for ongoing third-party testing—with results published for anyone to see.
Light Labs is an independent, ISO 17025-accredited laboratory that H2Tab uses for third-party product testing. They specialize in testing food and supplement products for things like heavy metals, contaminants, active ingredients, and other quality markers. Light Labs testing helps us independently verify product quality and gives our customers another layer of transparency.
We believe customers should be able to see the data behind the products they use, which is why we partner with independent laboratories like Light Labs as part of our broader commitment to quality, safety, and transparency.
Is H2Tab NSF Certified?
Yes. H2Tab holds two separate NSF certifications. NSF Certified confirms the product meets general safety standards, that the label accurately reflects what's in the tablet, and that it's screened for contaminants.
H2Tab carries the more rigorous NSF Certified for Sport® certification, which builds on the standard certification with additional batch-by-batch screening for hundreds of substances banned by major athletic organizations, giving athletes extra confidence in what they're taking.
Is H2Tab IHSA Certified?
Yes. H2Tab is IHSA certified, providing further independent verification of our product's quality and safety standards on top of our NSF Certified for Sport® and Light Labs testing.
Where and how is H2Tab manufactured?
H2Tab is manufactured in California, USA in accordance with Good Manufacturing Practices (GMP). This means every tablet is produced under consistent quality controls at every stage—from sourcing to packaging—so you can trust the same standard in every batch you receive.
Who tests H2Tab, and what do they test for?
In addition to our certifications, H2Tab partners with Light Labs, an independent testing laboratory, to verify each batch's hydrogen output and purity. This third-party testing confirms that H2Tab delivers exactly what's promised on the label.
Where can I view H2Tab's Certificate of Analysis (COA)?
