Phosphatidylserine (PS) is a fatty molecule that makes up roughly 15% of the brain’s phospholipid pool. Think of it as the “velcro” on neuron membranes—helping receptors, enzymes, and signaling proteins dock and work smoothly. Supplement trials show 200-300 mg/day can sharpen short-term memory, cut reaction-time errors, and blunt stress-hormone spikes within weeks. Soy- or sunflower-derived PS replaces the old bovine source but keeps the same bioactivity while avoiding prion concerns. Functional-medicine framing: PS restores membrane fluidity, supports acetylcholine production, and reins in cortisol, giving both cognitive lift and metabolic calm.
