Nutrient deficiency is a common cause of ongoing thyroid symptoms and often addressing nutrients can help relieve symptoms very quickly. ➡️ 🔵 Selenium at 200 mcg per day alone (or 83 mcg per day when combined with myo-inositol) has been shown to reduce anxiety, thyroid antibodies, and hair loss. 🔵 Ferritin is the iron storage protein and you need a blood test to measure it. Low levels can cause fatigue, heavy periods, hair loss, restless legs, and prevent proper conversion of thyroid hormone.
