• 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
