Quality & Third-Party Testing
Every product we sell is manufactured in a facility that holds Good Manufacturing Practice (GMP) certification, and every batch is tested by an independent lab before it reaches you. We believe you shouldn't have to take a brand's word for what's in the bottle — you should be able to see the actual documentation.
Below you'll find the real, unedited testing and certification records for our products, provided by our manufacturing partner.
What These Documents Actually Mean
GMP Certification confirms that the facility manufacturing our products has been independently audited and found to comply with FDA dietary supplement manufacturing regulations (21 CFR Part 111) and recognized industry quality standards. This covers everything from how raw materials are handled to how finished products are packaged, helping ensure consistency and safety at every step of production.
A Certificate of Analysis (COA) is a lab report for a specific production batch (identified by its lot number) confirming two things: potency, meaning the product actually contains the amount of active ingredient stated on the label, and purity, meaning the product has been screened for contaminants such as heavy metals, yeast, mold, and harmful bacteria.
Together, these two types of documents answer the two questions that matter most: is this made in a properly regulated facility, and is this specific bottle clean and accurately dosed.
Facility Certification
Our manufacturing partner's facility has been assessed and certified by UL Solutions, an internationally recognized independent certification body, for compliance with Good Manufacturing Practice standards under 21 CFR Part 111 and the Natural Products Association's GMP Standard for Dietary Supplements. This certification covers the manufacturing and packaging of powder, tablet, and capsule products, as well as softgel packaging — covering our full product line.

Product Certificates of Analysis
Each COA below corresponds to a specific manufacturing lot. The lot number on your product label or packing slip should match the lot tested in the corresponding document.
Creatine Monohydrate
Lot B25I013 — tested for potency (assay), identity, heavy metals (lead, arsenic, cadmium), and microbiological contaminants including E. coli, Salmonella, and Staphylococcus aureus. All results passed specification.
Magnesium Glycinate
Lot MGL250923 — tested for elemental magnesium content, heavy metals (arsenic, cadmium, lead, mercury), and microbiological contaminants. All results passed specification, with magnesium content exceeding the minimum label claim.
Vitamin D3 2,000 IU
Lot VS220698 — tested for active Vitamin D3 (cholecalciferol) content, disintegration time, and microbiological contaminants. All results passed specification, with potency exceeding the minimum label claim.
A Note on Lot Numbers
Dietary supplements are tested and certified by manufacturing batch, not by individual bottle. As new batches are produced, new COAs are issued. The documents above represent the testing for the batches referenced. If you'd like to confirm the lot number on the specific bottle you received, check the bottom of the label or your packing slip, and feel free to reach out if you have any questions.
