What It Does
Phosphatidylserine (PS) is a key phospholipid found in high concentration in brain cell membranes. It supports healthy cognitive function, enhances memory and focus, and helps maintain mental clarity under stress. PS also helps modulate cortisol spikes, making it ideal for stress management, sleep balance, and overall nervous system support.
Description
Thorne® Phosphatidylserine delivers 100 mg of pure PS — the primary phospholipid that keeps brain cell membranes flexible and functioning optimally. It plays a vital role in neuron communication, neurotransmitter activity, glucose utilization, and protection from oxidative stress.
Clinical research shows that phosphatidylserine supports cognitive health, especially in aging individuals, while also helping maintain a balanced stress response by modulating cortisol release.
This formula is NSF-certified, soy-derived but contains no soy protein, and is gluten-free.
