What is the Origin of Phosphatidylserine HPA Dampening?

The use of phosphatidylserine for stress modulation originates from neuroendocrinology research that identified its role in regulating the secretion of adrenocorticotropic hormone (ACTH) from the pituitary gland. The term reflects the specific clinical application of PS to downregulate the negative feedback loop of the HPA axis. This mechanism is an important component of restorative hormonal health protocols.

What is the Mechanism of Phosphatidylserine HPA Dampening?

Phosphatidylserine is thought to operate by enhancing the sensitivity of the glucocorticoid receptors in the hippocampus, a key brain region involved in HPA axis feedback. Increased receptor sensitivity allows the hippocampus to register circulating cortisol more effectively, thereby signaling the hypothalamus and pituitary to reduce the release of their respective stimulating hormones, CRH and ACTH. This enhanced negative feedback loop effectively "dampens" the excessive cortisol output, helping to normalize the diurnal rhythm.

Phosphatidylserine HPA Dampening

Meaning

Phosphatidylserine HPA Dampening is a targeted clinical strategy utilizing the phospholipid phosphatidylserine (PS) to attenuate, or dampen, an overactive Hypothalamic-Pituitary-Adrenal (HPA) axis, the body’s central stress response system. By modulating the HPA axis, PS helps to normalize elevated cortisol levels, particularly those associated with chronic stress and HPA axis dysregulation. This intervention is crucial for restoring proper hormonal rhythm and mitigating the systemic catabolic effects of prolonged high cortisol exposure.
