Lecithin does help indirectly
lower cholesterol by helping
to emulsify it, helping it
to move more smoothly through the blood vessels. The problem with cholesterol is when it oxidizes, which causes it to stick to the blood vessel walls, narrowing them. If it doesn't oxidize, if it keeps moving and doesn't stick, no problem. But by itself, lecithin probably won't be enough to lower your LDL and triglycerides, which are the two "bad" forms of cholesterol.
