Improve Concentration & Memory with Phosphatidylserine
Phosphatidylserine, or PS for short, belongs to a special category for fat-soluble substances called phospholipids. It is a natural compound that is found in the membranes of all the body’s cells, where it is essential for normal functioning. PS is especially highly concentrated in brain cells, where it helps regulate neurotransmitters, the chemical messengers that carry nerve impulses to and from the brain.
Role as a supplement :
PS may be helpful in supporting mental function. Studies indicate that taking supplemental PS may improve concentration and memory in people suffering from age-related memory loss, dementia, and Alzheimer’s disease
Evidence of efficacy :
Most of the research with PS has been done in Europe, where researchers report that taking 300mg a day can significantly improve memory and cognitive function (the ability to think, reason, and concentrate) among people who have suffered a decline in their normal mental abilities. The best results have been found when people were given PS in the early stages of dementia and Alzheimer’s disease. Although mental-function tests show significant improvements in Alzheimer’s patients, researchers caution that it’s generally not enough to make a real difference in the ability to function on a day-to-day basis.

Less research has been done on the benefit of PS among people suffering from normal age-related memory loss, but it is thought to be helpful. PS has not, however, been shown to improve a young, healthy person’s ability to think or remember facts. In contrast, older people seem to benefit from the supplements. In one study of 51 subjects over 71 years of age, those given PS for 12 weeks showed improvements in their abilities to maintain concentration and to recall names of familiar people, the location of misplaced objects, and details from the previous day and past week, and also improvements in their ability to concentrate. Follow-up studies showed that the benefits may last for several months after PS supplementation stops.
Originally PS was extracted fromcattle brains, but the scare over mad cow disease had researchers scrambling for a new source. PS now comes from soy, which is a natural rich source. At least one study found PS from soy to be just as effective as that extracted from cow’s brains.
PS is found in only trace amounts in a typical diet, with lecithin providing very small amounts. However the body manufactures what it needs from phospholipid building blocks.
Forms and usual dosage :
PS is available in capsule form and as a chewing gum. The recommended dosage is 300mg a day, divided into three doses, for 3-4 weeks. Once improvement is noted, a maintenance dose of 100mg/day is recommended. Capsules typically provide 100mg each, whereas 2 pieces of gum provide about 85mg/d
Added benefit of PS :
It lowers cortisol and helps with adrenal hormone balance!
Potential problems :
No side effects associated with PS have been reported, although one expert has suggested that taking PS at night may affect sleep.
Look for PS derived from soy in capsule form. It takes at least 6 or more pieces of gum a day to deliver the amount of PS found in 3 capsuls of 100mg
