PS and Energy
Phosphatidylserine also helps the brain process energy. The brain requires a lot of energy to carry out its functions though it weighs only about 1.35 kg. This organ uses at least 20 per cent of all the body's energy at rest and up to 60 per cent when we're doing hard mental work! Researchers can take advantage of sophisticated imaging instruments to examine how Phosphatidylserine affects energy in the human brain.
The vast majority of the cell energy functions are carried out by the membranes of the mitochondria, which are the energy powerhouses of the nerve cells. PS gets into these membranes, alongside coenzyme Qm and vitamin E and the protein cytochromes, improving energy efficiency. Since Phosphatidylserine is present in all living cells, they are likely to help all our tissues generate and utilize energy. PS works so well it may even help reverse human age-related memory loss.
In a 1991, double-blind trial done by Dr Thomas Crook and his associates at the Memory Assessment Clinics in Bethesda, Maryland. PS was found to improve name-face matching by about 12 years' worth. That is, when participants first took this test they performed at around age 64, then after three months on PS they had improved to an average 52 years. These subjects who were well into their 60s were performing on memory tests as if they were in their early 50s!
When PS was first researched as a dietary supplement, it had to be prepared from cow brain material. New technology has made it possible to enrich soy lecithin and so produce a safe dietary supplement that is highly bioavailability and crosses the blood-brain barrier. It is likely that once they get into the brain, the molecules migrate into the membranes of the nerve cells. There PS also serves as a storehouse for the related phospholipids PE (phosphatidylethanolamine) and PC (phosphatidylcholine), which are also cell membrane constituents.
A good dosing schedule for Phosphatidylserine is 300 mg per day for the first month, then 100 mg per day as a maintenance intake. Most people will notice a difference after three to six weeks. Those who are really having problems or prefer faster results can take up to 500 mg daily for that first month, then 200 to 300 per day thereafter. PS is free of major side effects. As an orthomolecular it seems compatible with all the nutrients and with many drugs in common use.
The numerous human clinical studies completed with Phosphatidylserine confirm that it consistently enhances memory and many other mental functions. Phosphatidylserine revitalizes the brain by giving it new energy and metabolic efficiency through the cell membranes. In some cases these lipids may rejuvenate the brain circuitry. Whether impaired mental performance is linked to aging, toxic or traumatic damage, cerebral insufficiency or non-specific causes, it is a nutrient unsurpassed for its clinical benefits to the brain.
