The evidence in words
How much to take
Iodized salt, dairy, and seafood cover most people. Pregnancy and lactation raise needs; prenatal vitamins typically include ~150 µg. Avoid high-dose kelp/iodine supplements.
Timing & separation
There are no strict timing conflicts on record for Iodine; consistency matters more than the exact hour for most goals.
Why the dose is what it is
The thyroid concentrates iodine and attaches it to tyrosine residues to make T4 and T3, which set metabolic rate throughout the body. Both too little and too much disrupt hormone production.
Bottom line
Use iodized salt or eat seafood/dairy; ensure adequacy in pregnancy. Don't megadose — the thyroid dislikes both extremes.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
