What is the Origin of Pregnenolone Protocol?

Pregnenolone's role was established with the discovery of the steroidogenesis pathway, identifying it as the first steroid produced from cholesterol in the mitochondria. The concept of a "protocol" developed in anti-aging and functional medicine, where low pregnenolone levels were linked to age-related cognitive and endocrine decline. The protocol's use is based on the biochemical principle of providing a foundational precursor to the hormonal system.

What is the Mechanism of Pregnenolone Protocol?

Following administration, pregnenolone is rapidly converted into various other active steroids in the adrenal glands, gonads, and brain, depending on the availability of specific enzymes like 17-alpha-hydroxylase and 3-beta-hydroxysteroid dehydrogenase. By increasing the substrate pool, the protocol allows the body's own regulatory systems to synthesize the necessary end-product hormones, acting as a broad-spectrum hormonal support strategy.

Pregnenolone Protocol

Meaning

A Pregnenolone Protocol is a therapeutic regimen involving the exogenous administration of the steroid hormone precursor pregnenolone, often to support downstream synthesis of other crucial hormones like DHEA, progesterone, cortisol, and the sex steroids. As the “mother hormone,” pregnenolone is a critical neurosteroid, and its protocol aims to restore optimal levels, thereby supporting cognitive function, mood stability, and the entire steroidogenic cascade. Clinical implementation requires careful monitoring due to its widespread metabolic influence.
