DHEA is the most abundant circulating steroid hormone, produced primarily by the adrenal zona reticularis. It serves as a precursor for both androgens (testosterone, DHT via 3beta-HSD and 17beta-HSD) and estrogens (estradiol, estrone via aromatase). DHEA-S (sulfated form) acts as a neurosteroid, positively modulating NMDA receptors and antagonizing GABA-A receptors (cognitive enhancement/alertness). It also modulates immune function (enhances Th1 immunity, IL-2 production), supports bone mineral density via estrogenic metabolites, enhances insulin sensitivity via PPAR-alpha activation, and opposes cortisol's catabolic effects (DHEA:cortisol ratio is a stress/aging biomarker).

Zinc is a cofactor for >300 enzymes and is a structural component of >2000 transcription factors (zinc finger proteins). It is essential for: immune function (T-cell maturation, NK cell activity, neutrophil function), DNA synthesis and repair, protein synthesis, wound healing, taste/smell perception, insulin storage and secretion (zinc-insulin hexamer in beta cells), testosterone synthesis (cofactor for 17-beta-hydroxysteroid dehydrogenase), and antioxidant defense (Cu/Zn-SOD, metallothionein induction). Picolinate chelation via picolinic acid (a tryptophan metabolite) enhances intestinal absorption via DMT1 transporters.
