What is the Origin of DHEA Supplementation Effects?

DHEA is a naturally occurring steroid produced primarily by the adrenal cortex, its name reflecting its chemical structure: dehydro-epi-androsterone. Supplementation effects are studied because DHEA-S (its sulfated form) is the most abundant circulating steroid hormone, and its levels decline significantly with age, leading to the hypothesis that replacement could mitigate age-related changes. The clinical investigation of its effects falls under the domain of anti-aging and preventive endocrinology.

What is the Mechanism of DHEA Supplementation Effects?

Once ingested, DHEA is metabolized in peripheral tissues into more potent sex steroids, including testosterone and estradiol, through the intracrine pathway. The observed effects are therefore a result of the downstream action of these converted hormones, which interact with androgen and estrogen receptors throughout the body. Furthermore, DHEA itself may act as a neurosteroid, directly influencing GABA receptors and brain function, contributing to its reported mood and cognitive effects.

DHEA Supplementation Effects

Meaning

DHEA supplementation effects refer to the systemic physiological and clinical outcomes resulting from the exogenous administration of dehydroepiandrosterone (DHEA), a precursor steroid hormone. These effects are highly variable, often studied in the context of age-related hormonal decline to potentially influence bone density, muscle mass, sexual function, and mood. Clinical practice requires careful monitoring due to DHEA’s role as a substrate for both androgen and estrogen synthesis.
