Antioxidant capacity is not a single number — it is the combined genetic output of five overlapping enzyme systems, each with its own variant layer. The Precision Peptide Genetic Test maps SOD2, GPX1, GCLC, NFE2L2, FOXO3, and more across 14 pathways, 49 peptides, and 150+ genetic insights, revealing the genetic architecture your antioxidant biology is built on.
