Phosphatidylserine (let's just agree to call it PS, shall we?) is a phospholipid compound, meaning it contains phosphate. It is found naturally in nearly every living thing. As a type of fat molecule, PS forms parts of cell membranes located everywhere but most importantly in the brain.
PS is believed to work with the nervous system by supporting the ability of neurotransmitters those chemical messengers which send and receive electrical impulses to bind to the membranes of brain cells. With the brain containing an estimated one trillion nerve cells, the result is support for brain function.
Unfortunately, the amount of PS in the body may decline over time due to age, stress, or deficient diet. When this happens, neural functions may be affected as well.
On a more positive note, an increase of PS in the brain may well support a healthy mind, an important benefit to the millions of Americans who say they are concerned about brain health.
PS is involved with other biological processes as well. It is credited with helping regulate biochemical reactions, influencing immune response, controlling the release of neurotransmitters, and possibly even helping protect cells from free radicals.
The earliest PS supplements were purified from the brains of cows, but in the 1990s (after concerns over the possibility of illnesses being transferred to humans) the source of the compound was switched to soybeans or other sources.
Referring to phosphatidylserine as PS is much easier, but if you want to show off to friends, it's pronounced fahs-ful-tie-dull-SEAR-reen. Try saying THAT three times quickly!
- PS supports brain function.
- PS is a natural substance found in brain cell membranes.
- PS levels in the brain may decline with age.
- Very limited and preliminary scientific research suggests that PS may reduce the risk of cognitive dysfunction in the elderly. The FDA concludes that there is little scientific evidence supporting this claim.
- PS appears in the brain, especially in the neurons the complex series of central nervous system pathways responsible for exchanging sensory information.
- PS supports a healthy mind.
- Brain Function:
Since PS is highly concentrated in brain tissue, it has received great interest as a possible health supplement for a healthy mind. More research needs to be done on how PS provides its benefits, but we do know that PS is an important cellular component.
- Exercise Performance:
Many people use PS to support recovery after heavy exercise like cycling, weight training and endurance running.
PS is found in meats, but it's most abundant in animal brains or organs such as liver and kidney. The highest PS content of all is found in the brains of cattle. Only small amounts are found in dairy products or vegetables, but here are some other options:
