Where the biochemistry happens for this system.
DNA methylation, homocysteine clearance, methyl-donor supply
Glutathione, SOD, catalase — quenching oxidative stress
Hydroxyapatite formation, osteoblast cofactors
Dopamine, serotonin, GABA precursors + B6/iron cofactors
CYP450 phase I + glutathione/sulfation/glycine phase II
Insulin sensitivity, GLUT4 translocation, glycemic control
Heme synthesis, erythropoiesis, oxygen carrying capacity
Cholesterol/triglyceride handling, β-oxidation of fatty acids
eNOS → nitric oxide, vasodilation, endothelial function
Cortisol synthesis, adrenal cofactor supply, calming neurochemistry
