Cofactors & Coenzymes

Cofactors and coenzymes are non-protein compounds involved in enzymatic reactions. This category groups the compounds in the Protide Health catalog that act as, or modulate, these biochemical cofactors rather than functioning as classic peptides. Every compound is third-party tested by an independent US lab and HPLC-MS verified to 99% purity, with a certificate of analysis published for each batch.

The collection includes NAD+ and the pH-stabilized NAD+ Buffered, both pyridine dinucleotide coenzymes; Glutathione, an endogenous tripeptide and redox cofactor; and 5-Amino-1MQ, a small molecule studied in NAD+ pathway research.

Each is lyophilized for stability and shipped from the USA within 24 hours. Review the published analytical data and third-party test results in our COA Library, or browse all research peptides.
