Primary Outcome Measures:

Numbers of subjects experiencing adverse effects as a measure of safety [ Time Frame: 3 months ] [ Designated as safety issue: No ]
Collected data on the numbers and types of any adverse effects related to the use of Anatabloc by subjects

Secondary Outcome Measures:

Measured changes in markers of autoimmune thyroiditis: changes in blood levels of anti-thyroid auto-antibodies, and changes in the volume and vascularization of the thyroid [ Time Frame: 3 months ] [ Designated as safety issue: No ]
To determine if dietary supplementation with Anatabloc has an effect on antithyroid autoantibody levels, thyroid structure, and/or thyroid function in subjects with autoimmune thyroiditis
