What is the Origin of Cortisol Timing Protocol?

This protocol is derived from clinical endocrinology, specifically focusing on the HPA axis feedback mechanisms and the clinical relevance of serum cortisol patterns. It acknowledges that the when of cortisol exposure is often as critical as the amount for overall metabolic regulation. It translates laboratory findings into actionable temporal strategies.

What is the Mechanism of Cortisol Timing Protocol?

The protocol works by using timed inputs—such as early morning bright light or strategic nutrient intake—to cue the pituitary and adrenal glands correctly. Proper timing supports robust morning cortisol release, essential for alertness and initiating catabolic processes for the day. Conversely, avoiding stimuli that elevate cortisol post-sunset preserves the necessary nocturnal drop, facilitating sleep and repair mechanisms.

Cortisol Timing Protocol

Meaning

A Cortisol Timing Protocol is a precisely scheduled regimen, often involving timed administration of specific nutrients, supplements, or light exposure, designed to optimize the natural diurnal rhythm of cortisol secretion. The goal is to reinforce the morning cortisol awakening response while ensuring nadir levels occur appropriately late in the evening. This protocol directly supports HPA axis health.
