Abstract Phosphatidylserine (PS) is a phospholipid which has been claimed to enhance neuronal membrane function, and can be derived from several sources. Earlier studies used brain cortex derived PS, of which the human tolerability of 300 mg daily in 130 patients has been shown. The human tolerability of PS derived from soy-bean has not been reported, although it is widely sold as a nutritional supplement which may improve cognitive function in the elderly. We report the results of a study of… Expand
Positive Effects of Soy Lecithin-Derived Phosphatidylserine plus Phosphatidic Acid on Memory, Cognition, Daily Functioning, and Mood in Elderly Patients with Alzheimer’s Disease and Dementia
Short-term supplementation with PS+PA in patients with AD showed a stabilizing effect on daily functioning, emotional state and self-reported general condition, and the data encourage long-term studies with PS +PA in AD patients and other elderly with memory or cognition problems. Expand
Safety of phosphatidylserine containing omega-3 fatty acids in non-demented elderly: a double-blind placebo-controlled trial followed by an open-label extension
The results of this study indicate that consumption of PS-DHA at a dosage of 300 mg PS/day for 15 weeks, or 100 mg PS /day for 30 weeks, is safe, well tolerated, and does not produce any negative effects in the tested parameters. Expand
The effect of soybean-derived phosphatidylserine on cognitive performance in elderly with subjective memory complaints: a pilot study
It is demonstrated that soybean-derived phosphatidylserine (SB-PS) may have favorable effects on cognitive function in elderly with memory complaints and suggests that SB-PS is safe for human consumption and may serve as a safe alternative to phosphate extracted from bovine cortex. Expand
Phosphatidylserine (PS) as a potential nutraceutical for canine brain aging: A review
Abstract Neurodegenerative processes are one of the main age-related features of dogs. Senile neurodegeneration can be clinically asymptomatic, "borderline" (i.e., a condition that is intermediateExpand
Effects of Phosphatidylserine Supplementation on Exercising Humans
Interestingly, recent findings demonstrating that short-term supplementation with S-PtdSer 750 mg/day improved exercise capacity during high-intensity cycling and tended to increase performance during intermittent running might suggest an innovative application for this supplement. Expand
The Effects Of Phosphatidylserine On Reaction Time And Cognitive Function Following An Exercise Stress
Phosphatidylserine (PS) is an endogenously occurring phospholipid that has been shown to have cognition and mood enhancing properties in humans, possibly through its role as an enzyme co-factor inExpand
Phosphatidylserine Containing ω–3 Fatty Acids May Improve Memory Abilities in Non-Demented Elderly with Memory Complaints: A Double-Blind Placebo-Controlled Trial
The results indicate that PS-DHA may improve cognitive performance in non-demented elderly with memory complaints and post-hoc analysis of subgroups suggests that participants with higher baseline cognitive status were most likely to respond to PS- DHA. Expand
Glycerophospholipid Supplementation as a Potential Intervention for Supporting Cerebral Structure in Older Adults
The current review aims to provide a theoretical basis for future clinical trials investigating the effects of GPL supplementation on cerebral structural integrity in older adults. Expand

It is demonstrated that orally administered SQ-PS dose-dependently aids in the improvement of memory deficits that occur during normal aging in rats, suggesting that SQ- PS may be a useful therapeutic agent in the treatment of diminished memory function in elderly people. Expand
The effects of phosphatidylserine on endocrine response to moderate intensity exercise
The findings suggest that PS is an effective supplement for combating exercise-induced stress and preventing the physiological deterioration that can accompany too much exercise. Expand


The Influence of Soy-derived Phosphatidylserine on Cognition in Age-Associated Memory Impairment
A daily supplement of S-PS does not affect memory or other cognitive functions in older individuals with memory complaints, and there were no significant interactions between treatment and ‘severity of memory complaints’. Expand
Cognition-enhancing properties of subchronic phosphatidylserine (PS) treatment in middle-aged rats: comparison of bovine cortex PS with egg PS and soybean PS.
It was concluded that S- PS, but not E-PS, may have comparable effects on cognition when compared with BC-PS. Expand
Effects of phosphatidylserine in age‐associated memory impairment
Analysis of clinical subgroups suggested that persons within the sample who performed at a relatively low level prior to treatment were most likely to respond to BC‐PS, and there was improvement on both computerized and standard neuropsychological performance tests, and on clinical global ratings of improvement.

Effects of phosphatidylserine in Alzheimer's disease.
Results suggest that phosphatidylserine may be a promising candidate for study in the early stages of AD, and those treated with the drug improved on several cognitive measures relative to those administered placebo. Expand

Abnormalities in the frontostriatal brain circuitry and possible hypofunctioning of dopaminergic pathways are apparent in ADHD, and are consistent with the benefits obtained in some instances by the use of methylphenidate (Ritalin) and other potent psychostimulants. Expand
