Criteria

Inclusion Criteria:

1. Mild TED of less than 18 months duration (as recorded by the patient).

2. No active state (Clinical activity score of less than 3).

3. No previous specific therapy for TED, except for local measures (artificial tear, head elevation, low salt diet).

4. Euthyroidism as a result of remission after a course of antithyroid drug (ATD) therapy, or euthyroidism for at least 2 months since commencing ATD or after thyroidectomy, or euthyroidism for at least 6 months after radioiodine therapy. Hypothyroid patients after thyroidectomy or radioiodine were replaced with levothyroxine. Euthyroidism was defined as normal serum free thyroxine, total or free triiodothyronine concentrations, and thyrotropin (TSH) levels below 4 mU/Liter Patients were kept euthyroid for the whole duration of the study.

5. Age 18-70 years.

Exclusion Criteria:

1. TED severity of more than mild TED.

2. Pregnancy

3. Drug and/or alcohol abuse

4. Severe concomitant illness

5. Inability to comply with the study protocol

6. No informed consent

7. Use of selenium- or vitamin/minerals-containing preparations in the last 3 months.
