Hormones
Thyroid + sex-hormone cofactors
Your endocrine system runs on a small set of trace minerals and fat-soluble vitamins that serve as the raw material and cofactors for hormone synthesis. Iodine and the amino acid tyrosine are literally built into thyroid hormone; selenium runs the enzyme that activates it; zinc and vitamin D are required for testosterone and the conversion enzymes across the sex-hormone axis; magnesium and B6 modulate the broader signaling network. Because these are needs in milligram-to-microgram amounts, a quiet dietary gap can throttle hormone output well before a blood test flags overt disease.
