Phosphotidylserine

Phosphotidylserine is derived from soy lecithin and is regarded as a supernutrient to the brain. It is a wonderful supernutrient with many beneficial effects, but I intend to mention its effect on memory in this chapter. It is a phospholipid and found in high concentration in the membranes of nerve cells. It facilitates the influx of nutrients into the cell. It also enhances memory and cognitive function by releasing acetylcholine and dopamine. In a study by Dr. Crook on patients who took PS for 12 weeks, it was shown to improve memory by 14 years. It is good for depression as it elevates mood and makes you feel happy. It has antioxidant properties and protects the cell membrane.43, 19

More than 25 studies on humans have been performed with PS of which 12 have been double blind placebo controlled (DBPC) trials. They have all shown memory improvement. PS is found in all vegetables and animal foods in particular soybeans, liver, eggs, wheatgerm and peanuts.

Doses of 100 to 300 mg per day are recommended with no side effects at these levels.
