Made in the U.S., tested by an independent lab, labeled by the rules.
Quality is the part of the business customers never see. Here is how we handle it.
Manufacturing
Every GS Labs product is produced in a U.S. facility certified to current Good Manufacturing Practices (cGMP) for dietary supplements. We do not import finished products.
Testing
Finished products are tested by an independent, accredited laboratory, and the certificates of analysis stay on file for every lot.
Labeling and claims
Our labels and listings follow FDA labeling rules for dietary supplements and FTC advertising standards. We describe what an ingredient supports; we do not claim to treat, cure, or prevent disease.
Marketplace compliance
We keep up with Amazon's dietary supplement requirements, including product documentation and testing records, so every listing stays eligible to sell.
