Description
Phosphatidylserine, also known as complex nervonic acid. Referred to as PS, it is extracted from the residue of natural soybean oil extraction. It is an active substance in cell membranes, especially in brain cells. Its functions are mainly to improve the function of nerve cells, regulate the conduction of nerve impulses, and enhance the memory function of the brain. Because of its strong lipophilicity, it can quickly enter the brain through the blood-brain barrier after absorption, soothe vascular smooth muscle cells, and increase the brain’s brain. blood supply.
Phosphatidylserine (PS) is known as a new “smart nutrient” after choline and “brain gold” DHA. Experts believe that this natural substance can help cell walls maintain flexibility, and can enhance the efficiency of neurotransmitters that transmit brain signals, helping the brain function efficiently and stimulating the activation state of the brain.
Phosphatidylserine is a component that occurs naturally in food and is also found in breast milk. Both meat and fish contain phosphatidylserine, and the content in the brain or internal organs (such as liver and kidney) is higher. Phosphatidylserine is found in very small amounts in dairy products and vegetables (except soy).
