What is β-Tetrahydrocortisone (β-THE) And Why Does the Hormone Zoomer Test for It?

Urinary cortisone metabolite

β-Tetrahydrocortisone (β-THE) is a urinary breakdown product of cortisone/cortisol metabolism. It reflects how the body inactivates and clears glucocorticoids and can help reveal patterns of adrenal output and enzyme activity when viewed with other hormone measures. Measuring β-THE adds clarity about cortisol turnover and clearance dynamics.

About β-Tetrahydrocortisone (β-THE)

Overview and History

β-Tetrahydrocortisone (β-THE) is a reduced steroid metabolite formed during the peripheral metabolism of cortisone and cortisol. Biochemically it falls into the class of tetrahydro metabolites created by reductase and dehydrogenase enzymes, notably those in the 11β-HSD and ketosteroid reductase families. Historically, tetrahydro metabolites were characterized in urine steroid profiling studies as markers of adrenal steroid turnover and hepatic/kidney clearance. β-THE’s core biological role is as an excreted end product of glucocorticoid metabolism, providing a window into the pathways that inactivate and remove stress hormones from circulation.

Interpreting Highs and Lows

Higher β-THE levels may reflect increased cortisone formation, faster cortisol turnover, or enhanced activity of inactivating enzymes—patterns associated with greater cortisol processing or altered enzyme balance. Lower β-THE levels may suggest reduced cortisone production, lower overall cortisol turnover, or shifts in enzyme activity that affect conversion and clearance. Interpretation depends on related measures (urinary cortisol, cortisone, other metabolites, and timed salivary cortisol) because isolated values don’t distinguish production from clearance or specific enzyme changes.

Featured Test

β-THE is included in the Hormone Zoomer to characterize cortisol inactivation and clearance alongside cortisol, cortisone, and other metabolites. It helps define adrenal output versus metabolic clearance and, when paired with timed saliva and urinary markers, refines understanding of stress rhythm, enzyme activity, and personalized endocrine patterns.

β-Tetrahydrocortisone (β-THE) FAQs

What is β-Tetrahydrocortisone (β-THE) and why is it important?

β-THE is a urine breakdown product produced when the body inactivates cortisone and cortisol. It acts as a marker of how quickly and through which pathways stress hormones are cleared. Tracking β-THE helps show patterns of cortisol processing that aren’t visible from a single blood or saliva value.

What does it mean if my β-Tetrahydrocortisone (β-THE) levels are low?

Low β-THE may indicate less cortisone formation or slower cortisol turnover, or it could reflect altered enzyme activity affecting the conversion and clearance of glucocorticoids. This pattern can point to reduced excretion of these metabolites, but needs comparison with cortisol, cortisone, and timing data to clarify whether production, conversion, or clearance is driving the finding.

What does it mean if my β-Tetrahydrocortisone (β-THE) levels are high?

High β-THE can suggest increased cortisone conversion or accelerated cortisol clearance and may reflect higher cortisol turnover or shifts in inactivating enzyme activity. Elevated values are clinically informative when interpreted with other adrenal metabolites and diurnal cortisol measures to determine whether the pattern arises from greater production, faster metabolism, or both.

Why is β-THE included in the Hormone Zoomer?

Measuring β-THE helps providers distinguish adrenal hormone production from downstream metabolism and clearance. Combined with the Cortisol Awakening Response, urinary cortisol/cortisone, and other metabolites, β-THE supports a more precise view of stress hormone rhythms and enzyme function to guide personalized assessment.
