A normal TSH, normal FT4, and low FT3 can indicate T4 to T3 conversion problems, and a normal or high TSH, normal FT4 and high FT3 can
indicate cellular resistance to FT3 which can still lead to hypothyroid symptoms because the active hormone can't get to the cell to do its job.
Found mostly in plant oils, such as black currant seed, hemp, borage, and evening primrose oils, GLA moistens the fatty layer beneath the skin and
increases cellular resistance, making it one of the best internal moisturizers.
If cellular resistance to thyroid hormone is accepted as a subset of thyroid disease not directly involving the thyroid gland, then our findings suggest that most FMS patients have thyroid disease.
We are convinced that the patients who improve or recover with supraphysiologic dosages of T3 have
cellular resistance to thyroid hormone.
