phosphatidylcholine lecithin

Phosphatidylcholine is the main phospholipid component of lecithin and a dietary source of choline. It’s a key part of cell membranes, supports liver and brain functions, and serves as a precursor to the neurotransmitter acetylcholine.

Supplement labels commonly list lecithin derived from soy, sunflower (seed), and egg yolk as the primary natural sources.

Product descriptions commonly state lecithin or phosphatidylcholine supports healthy brain function, memory and neurotransmitter (acetylcholine) production, and appear alongside language about focus, cognitive support and daily brain function.

Common co-ingredients include Alpha GPC, B vitamins (notably B6 and B12), botanical extracts such as ginseng, and other phospholipids used in cognitive formulas.

Some sunflower lecithin powder formulas are labeled vegetarian and 100% soy-free. Egg-yolk lecithin products are described in listings as soy- and seed-oil–free (note: egg-derived products are not vegetarian).
