Membrane and acetylcholine support.

Citicoline raises acetylcholine for focus and also feeds phosphatidylcholine into brain-cell membranes, while phosphatidylserine is a structural membrane fat tied to memory and a calmer stress response, so the two support cognition from complementary angles.

What to do

A reasonable nootropic pairing for memory and mental clarity, especially with age-related forgetfulness. Both are well tolerated; typical doses are around 250 mg of citicoline and 100 mg of phosphatidylserine, and both need a few weeks of consistent use to judge.
