What is Phosphatidylserine (PS)?
Phosphatidylserine (PS) is an essential natural phospholipid and a foundational component of human brain cell membranes. Concentrated in neuronal synapses, PS makes up approximately15% of total brain phospholipids, governing neuronal signal transmission, membrane fluidity, and neural metabolic balance.
The body naturally produces PS in limited amounts. Aging, mental overexertion, chronic stress, and fatigue gradually deplete these internal reserves, resulting in weaker memory, reduced mental clarity, and increased sensitivity to stress.
Widely recognized as a safe, effective nootropic ingredient, PS carries FDA-qualified cognitive health claims supported by decades of double-blind, placebo-controlled clinical trials and global nutritional research.
