Lipopolysaccharide (LPS), also known as endotoxin, is a component of the outer membrane of gram-negative bacteria in the gut and can be released into the bloodstream.

“So our gut is the home of like trillions of bacteria, right? We've got like trillions of bacteria in our gut. Many of many of them at the distal end of our gut in the colon. Some of these bacteria are good, the probiotic kind, and some are bad pathogenic kind. But regardless, bacteria in our gut, particularly the na the gram negative bacteria, have a component to their outer membrane. And the bacteria have a component called lipopolysaccharide. It's also referred to endotoxin. They're kind of the same thing, lipopolyaccharide.”
