What is the Origin of Micro-Dosing?

The term initially gained prominence in toxicology and drug development, where microdoses were used to study the pharmacokinetics of new compounds in humans without toxicity risk. Its application in clinical practice and wellness evolved from the desire to leverage the subtle, non-linear effects that very low doses of certain compounds can exert on receptor sensitivity and cellular signaling pathways.

What is the Mechanism of Micro-Dosing?

The proposed mechanism for efficacy involves stimulating or sensitizing cellular receptors without fully saturating them, often leading to a homeostatic or adaptive response. Instead of overwhelming the system, micro-dosing is hypothesized to fine-tune endogenous regulatory loops, potentially enhancing the body's own production or utilization of the hormone. This subtle biological input may restore balance by influencing complex feedback mechanisms within the neuroendocrine axes.

Micro-Dosing

Meaning

Micro-Dosing is a pharmacological strategy involving the administration of a therapeutic agent, such as a hormone, at a significantly lower concentration than the conventional therapeutic dose, often a fraction of the standard amount. The intention is to achieve a beneficial physiological or psychological effect without eliciting the full systemic effects or potential side effects associated with higher doses. In hormonal health, this approach aims to gently modulate the endocrine system rather than aggressively replace or suppress it.
