Phosphatidic acid (PA) and phosphatidylserine (PS) and are natural constituents of healthy brain cell membranes, which have been recognized since the 1970s as essential to normal neuronal functioning. PA is a precursor in the formation of other phospholipids, including PS and phosphatidylethanolamine (PE). Also, it has an impact on membrane rigidity/flexibility, which is important in modulating exo- and endocytosis. PS is also an important precursor for PE synthesis. Since PS predominantly occurs in brain cells, but normal diets do not include the consumption of brains, PS is available to our brains mostly via natural “production” in our bodies.

Here, we present a tabulated literature survey of clinical studies on PS and/or PA regarding brain function in elderly people. In addition we give a summary on two of our our already published pilot studies performed with a brain-health food supplement containing a proprietary blend of 100 mg PS and 80 mg PA produced from soy lecithin: A three-month double-blind, placebo-controlled study demonstrated the positive influence of three PS+PA capsules/ day, (300 mg PS+240 mg PA per day; n=40)) or placebo (n=32) on memory and mood in functioning, non-depressive elderly people with memory problems. In a two-month randomized, double-blind, placebo-controlled study, three PS+PA capsules/day (300 mg PS+240 mg PA per day; n=56) or placebo (n=40) improved daily functioning, mental health, emotional state, and self-reported general condition in patients with Alzheimer’s disease (AD).

Altogether there is encouraging clinical data that PS+PA supplementation could be beneficial to AD patients and other elderly people with memory or cognition problems. Long-term studies are, however, still lacking.
