- 01SeleniumModerate90% match
Selenium is a cofactor for glutathione peroxidase and deiodinase enzymes in the thyroid, and several trials report reduced TPO antibody levels with supplementation.
SuggestedSelenomethionine, around 100 to 200 mcg daily - 02Vitamin D3Moderate82% match
Vitamin D modulates regulatory immune function and is frequently low in people with autoimmune thyroid disease, so correcting deficiency supports immune balance.
SuggestedD3 (cholecalciferol) - 03IodineLimited60% match
Iodine is required for thyroid hormone synthesis, and only adequate, not excess, intake is appropriate in autoimmune thyroid disease.
SuggestedLow-dose iodine (around 150 mcg, the RDA), or dietary sources only - 04ZincLimited55% match
Zinc participates in thyroid hormone metabolism and conversion of T4 to T3, and deficiency can blunt thyroid function.
SuggestedZinc picolinate or bisglycinate, 10 to 25 mg daily - 05IronModerate52% match
Iron is needed for thyroid peroxidase activity, and low ferritin commonly coexists with Hashimoto's and can worsen fatigue and hair loss.
SuggestedIron bisglycinate, dosed to ferritin - 06Fish OilLimited45% match
EPA and DHA omega-3s support a less inflammatory immune environment, which is a reasonable general adjunct in autoimmune conditions.
SuggestedEPA/DHA triglyceride fish oil
