What natural remedies support thyroid health?

Ensuring adequate selenium (Brazil nuts, tuna, eggs) and iodine (seafood, seaweed in moderate amounts, iodised salt) from diet is the most fundamental nutritional support for the thyroid. Ashwagandha is used to support thyroid hormone levels and reduce thyroid stress; check with a doctor as it can affect thyroid tests. Stress management is important as chronic stress impacts the thyroid via the HPA axis.

What foods are good for the thyroid?

Selenium-rich foods (Brazil nuts, tuna, sardines, eggs, sunflower seeds), iodine-containing foods (seafood, seaweed in moderation, iodised salt), zinc-rich foods (pumpkin seeds, legumes), and iron-rich foods all support thyroid function. An anti-inflammatory diet rich in vegetables, fruits and healthy fats supports thyroid health broadly.

What foods should I avoid with thyroid problems?

Goitrogenic foods (raw cruciferous vegetables, soy, millet) can interfere with thyroid hormone production if eaten in very large amounts, though cooking significantly reduces this effect. For most people, moderate amounts of these foods are fine. Avoid excess iodine (large amounts of seaweed supplements), which can worsen autoimmune thyroid conditions.

Does ashwagandha help thyroid?

Some studies suggest ashwagandha may increase T3 and T4 thyroid hormone levels and support thyroid function. It can also help with the fatigue, brain fog and stress that accompany thyroid conditions. However, because it can affect thyroid hormones, anyone on thyroid medication should check with their doctor before using it, as it may require dose adjustment.

Can stress affect the thyroid?

Yes. Chronic stress elevates cortisol, which can suppress TSH, reduce conversion of T4 to active T3, and worsen autoimmune thyroid conditions (Hashimoto's and Graves'). Managing stress is a genuine part of thyroid health care, not just a general wellness recommendation.
