Your brain is composed of about 60 percent fat, so healthy fats are critical to your brain’s health. While good fats should be found in abundance in various unprocessed foods, phosphatidylserine is deficient in the modern Western diet.
Modern low-fat and low-cholesterol diets lack up to 150 mg per day of dietary phosphatidylserine. A vegetarian diet may undersupply as much as 200 to 250 mg per day. Other eating styles also create a demand for more phosphatidyl serine. For example, a diet deficient in omega-3 fatty acids may reduce the amount of phosphatidylserine in the brain by 28% and thereby impair your brain’s ability to form, store, process and remember.

To make matters worse, modern industrial production of fats and oils decreases all of the natural phospholipids—including phosphatidylserine.
Changes in our Western diet have resulted in a significant decrease in phosphatidylserine consumption in recent years, including rejection of fat, innards, organ meats and poultry skin (e.g., low-fat, low-cholesterol, and reduced-meat diets).

Phosphatidylserine can be found in meat and fish, but most abundant in organs not served in Western diets: brain and internal organs such as liver and kidney. Only small amounts can be found in dairy or vegetables, except for white beans. (135)

By building cell membranes, phosphatidylserine supplementation revitalizes the cells of your brain. Connections are formed; circuits are rebuilt. Scores of published human studies show that phosphatidylserine supplementation can:
Dietary intake of phosphatidylserine is essential because your body cannot synthesize the fatty molecule de novo. Phosphatidylserine supplementation has proven to restore activity of phosphatidylserine in your brain cell membranes, the chemical interaction and transfer of electrical impulses between neurons at both the sending and receiving ends. Thus, new information can more easily carve a new pattern and memories are reinvigorated. (209)
