Boron influences calcium, magnesium, and phosphorus metabolism, likely through effects on cell membrane function and transmembrane signaling. It reduces urinary calcium and magnesium excretion, increases serum 25(OH)D and estradiol levels, reduces SHBG (sex hormone-binding globulin) thereby increasing free testosterone, and inhibits inflammatory markers (CRP, TNF-alpha) via NF-kB modulation. Boron also inhibits serine proteases and may modulate the activity of steroid hormone hydroxylases. It plays a role in bone formation by influencing osteoblast and osteoclast activity.

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.
