The enzyme glutathione reductase, which requires NADPH as a cofactor, recycles GSSG back to GSH, maintaining this ratio [2]
The rationale for combining them is mechanistic complementarity (different signaling pathways, all three implicated in tissue repair and dermal remodeling) and clinical anecdote in the peptide-therapy community not formal head-to-head, combination-vs-monotherapy, or concentration-response data on the blend itself
For example, pairing Epithalon with peptides that support mitochondrial health, such as MOTS-c, may amplify its benefits by improving cellular energy and resilience
Macrophage glutathione content and glutathione peroxidase activity are inversely related to cell-mediated oxidation of LDL: in vitro and in vivo studies
Before visiting the laboratory: For follow-up testing, using similar fasting conditions, collection timing, and laboratory methods may make trends easier to interpret
