Iodine is the essential substrate for thyroid hormone synthesis. Thyroid peroxidase (TPO) uses iodine to iodinate tyrosine residues on thyroglobulin, producing monoiodotyrosine (MIT) and diiodotyrosine (DIT), which couple to form T4 (3,5,3',5'-tetraiodothyronine) and T3 (3,5,3'-triiodothyronine). Iodine is concentrated by the sodium-iodide symporter (NIS) in the thyroid, breast tissue, gastric mucosa, salivary glands, and choroid plexus. Beyond thyroid function, iodine has direct antimicrobial properties, modulates immune function, and may play a role in breast tissue health via iodolactone-mediated apoptosis.

Ascorbic acid is an essential electron donor and cofactor for numerous enzymatic reactions. It is required for collagen synthesis (prolyl and lysyl hydroxylases), carnitine biosynthesis, catecholamine synthesis (dopamine beta-hydroxylase), and alpha-ketoglutarate-dependent dioxygenases including HIF-prolyl hydroxylases and TET methylcytosine dioxygenases (epigenetic regulation). It regenerates oxidized vitamin E, supports immune function via neutrophil chemotaxis, phagocytosis, and lymphocyte proliferation. Liposomal delivery bypasses SVCT1/2 transporter saturation, achieving plasma levels closer to IV administration.
