In answer to your question and in my humble experience, it varies. Using an average daytime temperature of 98.6 F to limit sustained release T3 increases, in general, is a fairly good indicator; but it varies from person to person. You can have a normal or higher temperature and still do well with further increases of T3. Common reasons for this exception include: 1. an ongoing inflammatory problem such as Fibromyalgia, Thyroiditis, or some other autoimmune problem; and 2. fever from an infection. Also, if people have been on T4, I've seen them improve on T3 in spite of a "normal" temperature. Hope this helps. Doc Don (AKA D.
