It also mentions genetic testing for gluten intolerance and healthy ranges for vitamin D serum levels.

2. The thyroid gland produces the hormone
called Thyroxine (T4) this contains 4
molecules of iodine
T4 is converted into the much more active
form of thyroid hormone called
Triiodothyronine (T3) this contains 3
molecules of iodine
T4 is converted into T3 in the liver, muscle,
kidney and to a lesser degree in all other
body tissues
