1. ACCEPTANCE TESTING:Our initial acceptance testing ensures the raw ingredient does not include harmful amounts of heavy metals, alcohol (solvent) or microbials and is > 99% purity.
2. PRODUCT ASSURANCE TESTING:After bottling, we send a random bottle to a second lab for product assurance testing that verifies the finished product has at least the quantity of Mg per capsule specifed on the label.
3. QUALITY CERTIFICATION:Lastly, we ship a random sealed bottle to a third laboratory to verify the finished product meets the standards for strength and purity specified on the label. We use 3 DIFFERENT LABS to certify the strength and quality of every batch of our NMN nad NAD+ products.
