What this one is

Phosphatidylcholine is the main structural phospholipid in every cell membrane you have. Given by vein it loads your HDL particles so they pull cholesterol out of cells far more efficiently — the mechanism behind its long European record on cholesterol and arteries. It's also one of the most studied compounds in liver health, from membrane repair through to liver fat.

How this one differs

A single-ingredient infusion in a dextrose base. Ask your doctor whether it's appropriate for you.

Why we publish this

We post every formula because we know ours are the best.

Dosing an IV properly costs more to make. The two usual ways out are to charge double or to put less in the bag — we do neither, and take the smaller margin instead.

So every ingredient and every dose is on this page, at every size. Read ours, then go and try to read anyone else’s.
