Lecithin

Lecithin is a phospholipid mixture and a source of choline (primarily as phosphatidylcholine). RCTs support cholesterol reduction at 1.5-3.5g/day. Also serves as an emulsifier and absorption enhancer in supplement formulations. Sunflower lecithin is preferred by consumers avoiding soy. Note: phosphatidylserine is tracked as a separate nutrient. No established RDA/UL.
