Membranes

Phosphatidylcholine/PE synthesis, membrane fluidity & repair

Every cell is wrapped in a phospholipid membrane, and so is every organelle inside it — the membrane isn't just a wall, it's where a huge amount of signaling and transport happens. Choline builds phosphatidylcholine, the dominant membrane phospholipid; omega-3 DHA gives membranes (especially in the brain and retina) the fluidity that receptors and ion channels need to function; vitamin E embeds in the membrane to protect its fatty acids from oxidation. Membrane quality is literally built from dietary fat — the fats you eat become the fats your cells are made of.
