Conditions
Supplements and Hyperthyroidism or autoimmune thyroid disease
Caution
Ashwagandha may raise thyroid hormone levels. Avoid with hyperthyroidism; use caution with autoimmune thyroid disease.
Iodine can trigger thyroid dysfunction. In autoimmune thyroid disease, excess iodine can cause hypo- or hyperthyroidism.
Note
Broccoli-sprout compounds and the thyroid. Cruciferous compounds have long been suspected of affecting the thyroid, but in a 12-week randomized trial a sulforaphane-rich broccoli sprout drink did not change thyroid hormones or thyroid antibodies. Longer-term data are limited, so mention it if your thyroid is being monitored.
