Phosphatidylserine Powder

Phosphatidylserine is one of the few nutrients that can modulate the hypothalamic-pituitary-adrenal (HPA) axis—the body’s primary stress regulatory system—offering a natural alternative to anti-anxiety medications.
Normalization of cortisol levels: Chronic stress leads to overactivation of the HPA axis, resulting in elevated baseline cortisol levels that damage hippocampal neurons and induce anxiety, irritability, and sleep disturbances. Phosphatidylserine acts on the pituitary gland to inhibit the secretion of adrenocorticotropic hormone (ACTH), thereby reducing cortisol hypersecretion under stress conditions. This advantage is dose-dependent and highly targeted: unlike cortisol-blocking drugs, phosphatidylserine does not disrupt the normal stress response but rather prevents excessive cortisol release, maintaining the balance between stress adaptation and cellular protection.
Improvement of mood and resilience to stress: By reducing cortisol-induced neuronal damage,phosphatidylserine enhances the brain’s resilience to chronic stress. Clinical trials show that daily supplementation with 200–400 mg of PS lowers salivary cortisol levels in stressed individuals (e.g., office workers, students during exam periods) and alleviates symptoms of anxiety and fatigue. For individuals with mild depression,phosphatidylserine supplementation can enhance the efficacy of conventional antidepressants by promoting serotonin synthesis and release, with a favorable safety profile.
