Seeking Health Phosphatidylserine provides 100mg of plant-derived phosphatidylserine (PS) per capsule — a phospholipid concentrated in brain cell membranes that supports cognitive function, memory, stress response and healthy cortisol levels. Extensively studied in clinical trials for memory and cognitive support.

Frequently Asked Questions

What is phosphatidylserine and what does it do?

Phosphatidylserine (PS) is a phospholipid making up approximately 15% of total brain phospholipids, concentrated in neuronal membranes. It supports brain cell membrane fluidity, neurotransmitter release, glucose uptake in the brain, and healthy stress response by supporting HPA axis regulation.

What clinical evidence supports phosphatidylserine?

PS has been studied in numerous clinical trials for memory support in older adults, ADHD in children and adolescents, stress response modulation, and athletic recovery (it blunts exercise-induced cortisol elevation). It is one of the few supplements with an FDA-qualified health claim for cognitive function.

Is Seeking Health's phosphatidylserine plant-derived?

Yes. Seeking Health uses phosphatidylserine derived from sunflower or soy lecithin (plant-sourced), not the bovine brain PS used in older clinical trials. Plant-derived PS has similar clinical benefits in more recent studies.

Who would benefit most from phosphatidylserine?

Older adults experiencing age-related cognitive decline, students and professionals wanting to support memory and learning, athletes wanting to blunt exercise-related cortisol elevation, and those with ADHD or attention and memory difficulties.
