Frequently Asked Questions

Is lecithin the same as phosphatidylcholine?

No, lecithin is a mixture of phospholipids that contains phosphatidylcholine as its primary component (20-25% in soy lecithin). Pharmaceutical-grade PPC (polyenylphosphatidylcholine, as in Essentiale) is a purified, concentrated form containing 72-96% phosphatidylcholine. For liver support, concentrated PPC capsules are more effective than general lecithin supplements because they deliver a standardized, higher dose of the active phospholipid.

Can phosphatidylcholine help with fatty liver (NAFLD)?

Yes, phosphatidylcholine directly addresses one of the key mechanisms in fatty liver. The liver needs PC to assemble and secrete VLDL particles, which transport fat out of the liver. When PC is insufficient, fat accumulates in hepatocytes. Multiple clinical studies show PPC supplementation at 1200-1800mg/day reduces liver fat content, lowers enzymes, and improves ultrasonographic findings in NAFLD patients.

Should I take phosphatidylcholine or just choline?

For liver support specifically, phosphatidylcholine is preferred over plain choline. While choline supplements (choline bitartrate, CDP-choline) can prevent choline deficiency, they do not directly repair hepatocyte membranes the way intact phosphatidylcholine does. PPC integrates directly into damaged cell membranes, restoring their structure. For general choline needs (brain health, methylation), either form works.
