KINETICS AND SAFETY OF SOY LECITHIN PHOSPHATIDYLSERINE (PS) ABSORPTION.
This report summarizes results of a study on the kinetics of soy lecithin phosphatidylserine (PS) absorption by the body. The study was carried out in July 1996 with standard soft gelatin capsules containing soy lecithin PS complex supplied by Lipogen Ltd.

 

EFFECT OF SOY LECITHIN PHOSPHATIDYLSERINE (PS) COMPLEX ON MEMORY PAIRMENT AND MOOD IN THE FUNCTIONING ELDERLY
This double-blind study assessed the influence of plant phosphatidylserine (PS) product on memory and mood in functioning elderly, aged 60-80 years old, and living in the community. Seventy-two subjects, randomly assigned to placebo and therapy groups, were treated for three months with 300 mg. PS daily. Results showed a large and statistically significant positive influence of treatment on both memory and mood, whereas influence of placebo was small and non-significant. This influence was stronger with higher pre-treatment memory scores.

 

LONG TERM EFFECTS AND SAFETY OF SOY LECITHIN PHOSPHATIDYLSERINE (PS)
TREATMENT IN COGNITIVELY IMPAIRED OUT-PATIENT GERIATRIC POPULATION
Phospholipids are present in nerve cell membrane, and are essential for cell membrane functioning. The amount of Phospholipids in neuronal membranes declines with age, particularly of PS, which correlates with the level of cognitive impairment.

The Geriatric Institute for Education and Research in Kaplan Medical Center has performed in the past two studies on soy lecithin PS complex, one with normal aged patients, and the other with Alzheimer's Disease patients. The patients of these studies showed improvement.
