Phosphatidylserine 150 mg sunflower lecithin sourced 60 vegan capsules

Phosphatidylserine delivers 150 mg of phosphatidylserine (PS) per capsule, sourced from sunflower lecithin (Helianthus annuus seed) completely soy free. Each capsule is derived from 300 mg of sunflower lecithin. Phosphatidylserine is a phospholipid that forms a key structural component of neural cell membranes and is one of the most researched nutrients for memory and cognitive function support in adults.

What Is Phosphatidylserine?

Phosphatidylserine (PS) is a fat-soluble phospholipid found in high concentrations in the brain, where it constitutes approximately 15% of the total phospholipid content of neural cell membranes. PS plays a central role in maintaining membrane fluidity and integrity, supporting receptor function, neurotransmitter signalling, and glucose metabolism in brain cells. PS levels in the brain naturally decline with age, which is why supplementation is commonly used to help maintain cognitive health in adults.

Sourced from Sunflower Lecithin Soy-Free

Most phosphatidylserine supplements on the market are derived from soy lecithin. This formula uses sunflower lecithin (Helianthus annuus seed) as the phospholipid source, making it completely soy free. Each 150 mg capsule is derived from 300 mg of sunflower lecithin. This formulation is suitable for individuals with soy sensitivities or those who prefer to avoid soy-derived ingredients, without any compromise to the phosphatidylserine content or quality.

Memory and Cognitive Function

PS is one of the most extensively researched phospholipids for cognitive support in adults. It supports neurotransmitter systems involved in memory formation and recall, and helps maintain the structural integrity of neural cell membranes required for efficient neural communication. PS supplementation has been studied in the context of age related cognitive decline, memory performance, and information processing speed.

Phosphatidylserine and the Stress Response

PS has been studied for its role in supporting a balanced cortisol response to physical and psychological stress. Chronically elevated cortisol is associated with impaired memory and cognitive function. PS supplementation has been investigated for its potential to support a more measured hypothalamic pituitary adrenal (HPA) axis response under conditions of physical and cognitive stress.

Clinical Research

Phosphatidylserine and the human brain: a systematic review of clinical studies

Nutrition (2015), Glade MJ & Smith K

A comprehensive systematic review of clinical studies examining the effects of phosphatidylserine supplementation on human brain function. The review found consistent evidence supporting PS's role in maintaining cognitive function, memory, and mental clarity in adults, and highlighted its safety profile and mechanisms of action including support of neural membrane integrity, neurotransmitter signalling, and glucose metabolism in the brain.

Blunting by chronic phosphatidylserine administration of the stress induced activation of the hypothalamo-pituitary-adrenal axis in healthy men

European Journal of Clinical Pharmacology (1992), Monteleone P et al.

A double blind, placebo controlled study examining the effect of phosphatidylserine supplementation on the hypothalamic-pituitary-adrenal (HPA) axis stress response in healthy men. The study found that PS supplementation significantly blunted the cortisol and ACTH response to physical stress, supporting PS's role in modulating the stress response and its potential to help maintain cognitive function under conditions of elevated cortisol.

The effects of phosphatidylserine on memory and cognitive function in older adults

Neurology (1991), Crook TH et al.

A double blind, placebo controlled clinical trial evaluating the effects of phosphatidylserine supplementation (300 mg/day) on memory and cognitive function in older adults with age-associated memory impairment. The study found significant improvements in memory tasks, learning, and cognitive performance in the PS group compared to placebo, supporting the use of phosphatidylserine for cognitive and memory support in adults.
