Zinc supplementation appears to enhance thyroid hormone levels, particularly T3, and may help treat subclinical hypothyroidism associated with zinc deficiency.
If you have hypothyroidism or fatigue, check your zinc levels. Correcting a zinc deficiency may improve thyroid hormone levels, particularly T3.
