Phosphatidylserine: A Brain Phospholipid for Cortisol, Stress, and Cognitive Support
Thorne’s Phosphatidylserine is a high-quality supplement featuring a key phospholipid that is vital for the structure and function of every cell in the body, particularly in the brain. Phosphatidylserine (PS) plays a crucial role in supporting healthy cognitive function, memory, and focus. It is also a premier nutrient for managing the body’s stress response by helping to normalize cortisol levels. This makes it an exceptional choice for students, professionals, athletes, and anyone seeking to enhance mental clarity and promote a balanced response to daily stress.
How It Works: Balancing Cortisol and Supporting Brain Cells
Phosphatidylserine’s benefits stem from its integral role in cell membrane health and its ability to modulate the body’s primary stress hormone, cortisol.
Promoting a Healthy Stress Response
During periods of stress, the adrenal glands release cortisol. While essential in the short term, chronically elevated cortisol can negatively impact sleep, mood, and cognitive function. Phosphatidylserine has been clinically shown to help moderate the body’s stress response and blunt adrenal output of cortisol. This can help lower evening cortisol levels, which supports more restful sleep and promotes a calmer, more relaxed state of mind during the day.
Enhancing Cognitive Function
As a crucial component of nerve cell membranes, PS is essential for neuron communication and the transmission of brain signals. It supports the production of key neurotransmitters like acetylcholine, which is linked to memory and learning. By supporting overall brain cell health and facilitating neurotransmitter signaling, supplemental PS helps to maintain healthy memory, focus, and concentration, particularly as a part of a healthy aging regimen.
