Soy lecithin is a fatty substance from soybeans, rich in phospholipids such as phosphatidylcholine, which help build cell membranes and carry fats around the body. With no single main use standing out, the best-supported finding is for high cholesterol, where a small trial found LDL cholesterol improved, though the evidence is limited. Another small study saw cortisol go down, but HDL showed no clear difference, and all of this comes from very small groups.
