What is Phosphatidylserine?
Phosphatidylserine is a phospholipid consisting of glycerol, fatty acids, phosphate and the amino acid serine.
Health Benefits of Phosphatidylserine
Phosphatidylserine and Cortisol
Simply put, phosphatidylserine is an extremely effective cortisol blunting supplement. It has also been shown to reduce post-workout exercise induced cortisol, which in turn facilitates recovery, fat loss and muscle repair.
Phosphatidylserine and Memory
Phosphatidylserine may help improve memory function in older adults, suggests a 2010 study published in the Journal of Clinical Biochemistry and Nutrition. For the study, 78 elderly people with mild cognitive impairment were assigned to six months of treatment with phosphatidylserine supplements, or a placebo.
In tests performed at the end of the six-month period, participants with relatively low memory scores at the start of the study were found to have experienced a significant improvement in memory.
Phosphatidylserine and Depression
Preliminary research indicates that phosphatidylserine holds promise in the treatment of depression. In a 2004 study published in Progress in Neuropsychopharmacology and Biological Psychiatry, for example, tests on rats demonstrated that phosphatidylserine may offer an antidepressive effect. However, more research is needed before phosphatidylserine supplements can be recommended for treatment of depression in humans.
Phosphatidylserine and ADHD
Using phosphatidylserine in combination with omega-3 fatty acids may aid in the treatment of ADHD in children, suggests a 2012 study published in European Psychiatry.
For the study, 200 children with ADHD were assigned to 15 weeks of treatment with either a placebo or supplements containing phosphatidylserine and omega-3 fatty acids.
Study results revealed that participants treated with the combination of phosphatidylserine and omega-3 fatty acids experienced a significantly greater reduction in hyperactive/impulsive behavior and a greater improvement in mood (compared to those given the placebo).
