If it tends to run high
- Switch to Green Tea
L-theanine in green tea calms without suppressing thyroid, unlike reducing iodine.
If it tends to run low
- Iodine-Rich Foods
Seaweed, eggs, and dairy provide iodine — the raw material for T3/T4 production.
- Selenium Sources
Brazil nuts, fish, and sunflower seeds support the conversion of T4 to active T3.
- Morning Exercise
Light morning activity stimulates thyroid hormone release and improves metabolic rate.
