Chemical Persistence

Meaning

In the context of hormonal health, chemical persistence describes the prolonged presence and biological activity of an administered or naturally occurring compound within the physiological system, extending beyond its typical pharmacokinetic half-life. This concept is particularly relevant to synthetic hormones or endocrine-disrupting chemicals (EDCs) that may accumulate in lipophilic tissues. High persistence can lead to sustained receptor activation or antagonism, potentially contributing to chronic hormonal dysregulation or toxicity. Understanding this characteristic is essential for designing safe and effective dosing protocols.
