BioPS® 50% Soy Derived Phosphatidylserine
PS is formed in the body from the amino acid L-serine,
glycerophosphate, and two fatty acids. Some PS is
converted to phosphatidylethanolamine, which is in turn converted
to phosphatidylcholine. Phosphatidylethanolamine can also be
enzymatically converted to phosphatidylserine; however, these
conversions are energy costly.1

Clinical Applications - Alzheimer’s Disease
Phosphatidylserine has received attention for treatment of AD.
Generally, PS produces significant improvement in anxiety,
motivation, memory, and cognition.1,2-8 At daily doses of 200-300 mg for up to six months, PS consistently
improved clinical global impression and activities of daily living.
In a double-blind, placebo-controlled trial involving 425 patients
with moderate-to-severe cognitive loss, PS significantly improved
memory, learning, motivation, socialization, and general
“adaptability to the environment.”9 In another placebo-controlled study of 142 AD patients, PS was
given (200 mg/day) for three months, and the patients were followed
for 24 months. A ubgroup of patients with severe cognitive
impairment demonstrated significant improvements based on the
Blessed Dementia Scale (activities of daily living, information
processing, personal and non-personal memory) three months after
treatment cessation.10 In other studies, most using 300-400 mg/day, improvement tended to
be the greatest in those with less severe cognitive impairment,1,2-4,6 and in one study were transient, fading after 16 weeks.2
