REVIEW: In illness, T3 testing is more reliable than TSH
In Chatizomaris et al’s (2017) article, Table 2 illustrates the many health conditions — beyond thyroid gland failure — in which a TSH test result is NOT indicative of the patient’s true thyroid hormone status. The table shows what usually happens to thyroid hormones and TSH in a patient who is NOT taking any thyroid…

REVIEW: Non-thyroidal influences on thyroid hormones
This excellent scientific article by Chatzitomaris et al discusses the various NON-thyroidal causes of thyroid hormone T4, T3 and pituitary TSH imbalance.

2018 study on T4 and T3 in breast cancer
Published August 2018, a new study of T4 and T3 hormones and obesity in relation to breast cancer risk found that higher levels of T4 hormone conferred greater risk, while higher T3 levels had a protective effect. The article Ortega-Olvera, C., Ulloa-Aguirre, A., Ángeles-Llerenas, A., Mainero-Ratchelous, F. E., González-Acevedo, C. E., Hernández-Blanco, M. de L.,…

Cardiovascular disease research should focus more on patients’ T3 levels than TSH
Science has already shown that at T3 is more important than TSH to the functional parameters of the cardiovascular system: At the molecular and tissue level, the T3 hormone directly affects the cardiovascular system in a myriad of important ways (see “Low T3’s effects on the cardiovascular system.”) Why, then, when researchers shift their focus…

Low T3 effects on the cardiovascular system
When people think of cardiovascular symptoms and thyroid hormones, they usually think first about hyperthyroidism (excess thyroid hormone). However, hypothyroidism (deficient thyroid hormone) has an equally powerful effect on the heart and blood vessels. It can just be slower, more long-term, and less dramatic. Did you know? Heart failure occurs in hypothyroidism, too. (See below)…
