Features and benefits


Phosphatidylserine (PS) belongs to a class of nutrients called phospholipids, which are fats that play an integral role in cell membrane function and structure. 

We need our membranes to filter nutrients in and out, to communicate with other cells and to regulate cell growth. PS is crucial for the maintenance of healthy cell membranes throughout the body, but it’s most highly concentrated in the nerve cells of our brains. 

Unfortunately, as we get older, our production of PS decreases, which can lead to cognitive decline. Research into supplemental PS shows that it can support brain function, especially with respect to tasks that require memory, vocabulary and concentration, as well as improve mood and reduce stress. Studies also point to benefits for Alzheimer’s patients.

PS may benefit all of us, because we’re exposed to the free radicals formed from breathing in cigarette smoke, alcohol consumption, environmental pollution or chronic emotional stress, factors that have a cumulative negative effect on the brain.

Natural Factors uses Sharp-PS® GREEN, a highly absorbable and stable form of PS that is 100% soy-free, derived from non-GMO sunflower oil.

How it works


Phosphatidylserine helps maintain the cell membranes in our brains and is responsible for functions such as moving nutrients in and out of cells, assisting with cell-to-cell communication, and regulating cell growth. 

PS increases the fluidity and efficiency of cell membranes, which revitalizes membrane function and protects cells from damage. This leads to a host of benefits like improved cognition, concentration, and memory. 

Not only does PS affect the outer nerve cell membranes, it also becomes incorporated within the inner cell membranes and improves energy production. When the individual cells of the brain have more energy, the brain as a whole is energized, has more power, and functions better. 

Normally, our brains can manufacture enough phosphatidylserine, but there is evidence that insufficient production in the elderly may be linked to depression and/or impaired mental function. 

Scientists theorize that patients experiencing dementia or memory impairment is a result of changes or abnormalities in the fat composition of the brain, and supplementation with PS can help bring neural function back to normal. PS has also been shown to increase the production of the brain’s neurotransmitters (acetylcholine, norepinephrine, serotonin, and dopamine) and reduce neuron loss.
