Genestra Phosphatidylserine, 30 Capsules

Helps to support the maintenance of cognitive function • Provides 300 mg of phosphatidylserine per daily dose Phosphatidylserine (PS) is a phospholipid found in neuronal cell membranes that helps to support cognitive function.¹ PS helps to maintain optimal levels of membrane fluidity, which is necessary for proper enzyme and receptor activities.¹ It also mediates the activity of several neurotransmitters, including norepinephrine, dopamine and serotonin.¹ In a randomized, placebo-controlled trial involving 73 elderly participants with mild memory impairment, daily supplementation with 300 mg of PS for 6 months significantly improved word recall rates.² The improvement in cognitive function extended three months after the treatment period ended.² PS can be metabolized into the choline-containing neurotransmitter acetylcholine, which can influence synaptic plasticity, the ability to strengthen the transmission at a synapse.^3,4 Increases in synaptic plasticity are central to improving memory and learning.⁴ PS supplementation may increase brain-derived neurotropic factor, a protein that may influence the survival of neurons and may also have a role in enhancing memory and learning.⁵
