Physiological Concentrations

Meaning

Physiological concentrations refer to the range of hormone or substance levels naturally found circulating in the blood or present within tissues that are necessary to maintain normal, healthy biological function. These concentrations are typically within a tightly regulated, narrow homeostatic range, ensuring optimal cellular signaling and metabolic activity without causing toxicity. Administering exogenous compounds at these concentrations is a critical therapeutic goal to mimic the body’s native endocrine environment, promoting health without inducing pharmacological side effects.
