Phosphatidylserine
A fat concentrated in brain cell walls. The idea is that topping it up helps signalling — not firmly established in people.
Say that in clinical terms
Phosphatidylserine is a phospholipid concentrated in neuronal cell membranes; supplementing it is theorized to support membrane fluidity and cell signaling involved in memory formation, though the human mechanism is not firmly established.
