Phosphatidylserine has been shown to enhance brain function, reduce stress & lower cortisol.
Click here for a lot of great information on Phosphatidylserine, including studies on Memory, ADHD, Stress and Athletic applications.
Like most nutritional supplements, there is a vast range in the quality and price of raw materials for Phosphatidylserine. Now Foods uses Leci-PS™, Phosphatidylserine manufactured by Cargill.
Phosphatidylserine is a phospholipid compound derived from soy lecithin that plays an essential role in cell membrane composition and intercellular communication. Phosphatidylserine is a major structural component of neural membranes where it asists in the conduction of electrical impulses and facilitates the activity of neurotransmittters involved in learning, memory and mood. These properties make NOW® Phosphatidylserine an ideal supplement for the support of cognitive function.*

Phosphatidylserine is a phospholipid
- a molecule made up of two fatty acids and a phosphate group attached to a glycerol
backbone. It is concentrated in cells of the brain, where it may
be related to brain cell function and neurotransmitter metabolism. Phosphatidylserine
is also found in other cell membranes, such as muscle tissue and cells of the
immune system, where they may play both a structural and functional role in muscle
metabolism and immune system function.
• Prevents muscle breakdown
• Stimulates immune function
• Maintains brain function, memory and cognitive ability
Phosphatidylserine has been shown to reduce blood levels of cortisol - a hormone
produced in response to stress. One of the effects of elevated cortisol production
is accelerated amino acid catabolism - which could lead to muscle breakdown. Suppression
of cortisol levels could theoretically maintain muscle mass during periods of
increased stress and intense training.
Scientific Support Phosphatidylserine, like other phospholipids, is a major constituent
of cellular membranes. Maintenance of membrane integrity is a crucial component
of proper function, but there is little direct evidence that Phosphatidylserine
supplements improve membrane integrity or cellular function. Phosphatidylserine
has, however, been linked to a suppression of cortisol secretion during periods
of intense training (20-30%) - an effect which may help enhance recovery and repair,
particularly following intense exercise or injury.
As a brain-support nutrient,
Phosphatidylserine has been validated through double-blind trials for improving
memory, learning, concentration, word recall, and mood in middle-aged and elderly
subjects with dementia or age-related cognitive decline. In animal studies,
long-term phosphatidylserine treatment has been shown to maintain the integrity
of neuronal structures in the brain which have been altered by the aging process.
These are logical findings, as Phosphatidylserine is particularly enriched in
the brain and has an excellent benefit-to-risk profile when compared to traditional
treatments for memory loss.
It is interesting to note
that Phosphatidylserine could also be considered a “general stress”
nutrient – providing benefits for athletes subjected to the physical stress
of exercise as well as for those individuals who are under chronic emotional
stress from hectic lifestyles, job deadlines and many of the other stresses
of modern life.
