Certificate of Analysis

Collagen Peptides

Hydrolyzed collagen is defined by the size of its peptides, not by its protein content. A powder can test as pure protein and still be useless if the chains were never broken down small enough to absorb. That is why every lot of Collagen Peptides is checked for molecular weight distribution alongside protein content. Type I and Type III bovine collagen are confirmed by peptide profile, and the gelatin fraction is identified separately. The 3,000 mg on the panel is hydrolyzed peptide, not total capsule weight.

Every Lot, Before Release

What We Test For

Peptide identity confirms the collagen is bovine Type I and Type III as declared. Molecular weight distribution is measured to verify the peptides are hydrolyzed into the low weight fraction the body can absorb. Total protein content is quantified against the 3,000 mg declared per serving. The gelatin and aloe vera fractions are identified separately from the collagen. Heavy metals are screened by ICP-MS for lead, arsenic, cadmium and mercury. Microbiological testing covers total plate count, yeast and mold, E. coli, Salmonella and Staphylococcus aureus.

How to Check a Lot

Reading Your Certificate

A certificate of analysis is a one page summary of what an independent laboratory found in one specific lot. The lot number at the top matches the number printed on the base of your bottle, so you can confirm you are reading the right document. Each row lists a test, the specification it has to meet, and the result that was actually measured. Results appear as a numeric value, as Pass, or as Not Detected, which means the substance was below the laboratory's limit of detection. Heavy metal results are reported in parts per million and compared against the limit set for that ingredient class. If a single row falls outside specification the lot is rejected and no certificate is ever issued. Certificates are added to this page as each new lot clears testing.
