Biochemical Pathway
Thyroid
T3/T4 synthesis from tyrosine + iodine; deiodinase cofactors
Primary cofactors
The load-bearing nutrients — if these are deficient, this pathway slows down. Click any to see daily targets, food sources, and supplements that supply it.
Additional cofactors
Nutrients that contribute to this pathway but aren’t the single load-bearing inputs.
Biomarkers on this pathway
Lab markers that report on how well this pathway is running. When one of these is out of range, this pathway is often where the upstream issue lives.
