In this short video, Dr. Aaron Hartman explains how supplementing with healthy phospholipids—particularly phosphatidylcholine (PC)—can serve as a form of cellular medicine. He identifies organ meats, egg yolks, and caviar as natural dietary sources of these lipids and recommends a daily dose of about one tablespoon of a PC supplement. Hartman describes the mechanism as phospholipids acting like a soap on cell membranes, helping to “wash out” cellular debris. A noticeable side effect is a temporary darkening of stool for a couple of weeks, which he frames as evidence of the cleansing process. He emphasizes the profound impact this simple dietary addition can have on cellular health.

The other thing is adding in phospholipids, healthy phospholipids. The primary source for these in nature is organ meats and egg yolks and caviar, which, you know, is always fun to try to figure out how to get that. But phosphatidylcholine, PC, is a great source for these. I'm usually doing a tablespoon a day of this. And one of the first things people notice when you start using it is their stool change and get kind of dark. And it's literally washing out— phospholipids actually act like soap. On your cell wall membrane. So one of the things you'll notice is actually changing your stool for a couple of weeks because you're literally just washing out all the gunk and stuff. It's actually pretty profound.
