   Phosphyatidylserine is used in Europe for Alzheimer's disease and cognitive problems [References]. Studies demonstrate that adding PS to the diet may prevent, limit, or even repair these deficit with improvements in cognitive function such as  memory, judgment, and abstract thought. Improvements in concentration, recall, and even learning have been reported.  Specifically measured have been improvements in learning names, faces, and phone numbers, remembering lost items and improvements in reading skills. 
More than a dozen double-blind, randomized, placebo-controlled trials have been conducted in the United States and Europe.  Clinical studies have included double-blind trials which in older subjects (50 or more) yielded benefit, in some studies producing a reduction in the "cognitive mental age" of those taking it by 10 years or more.  In other clinical studies, PS was found to improve EEG alpha rhythm in young men reversing its decline with age. 

    PET [positron emission tomographic] has revealed that PS improves brain glucose consumption and has even improved the 24-hour rhythm of TSH (thyroid-stimulating hormone) secretion in older men.

The color scale semiquantitatively indicates regional glucose metabolism with red being most intense and blue, least intense (see color scale). top, before PS administration; bottom, after 500 mg PS administered daily for three weeks.  The brain metabolism appears increased.

    How long does the Effect Last?

  Are there other effects of Phosphatidylserine?

  What dosages are used?

   Are there side effects?

 Does PS come from bovine (cow) brain?
   No.  NOT PS used in SMART-MINTS.  Other forms of PS supplements do however.   We are concerned about even the possibility of "mad cow disease" and our only source of PS is from purified plant product rather than the conventional cow brain phospholipid extract.  The vegetable purified product has the similar effects without the risk. 
Our PS is only from plants and is rated GRAS (Generally Recognized As Safe). 

 Does PS have any contraindications?
   Contraindications include people with soy allergy, intolerance to lecithin, and people with very rare antiphospholipid autoimmune syndromes.  Toxicological assessments have revealed that PS is not mutagenic, carcinogenic, or teratogenic in animals.  Studies on pregnant women apparently are not available.
