What is it? / Overview

Lecithin is a source of phosphatidylcholine, a building block used in cell membranes and bile. Small studies and lactation-consultant clinical experience suggest it may reduce recurrent clogged ducts during breastfeeding by decreasing milk fat viscosity; evidence for general cholesterol-related claims is weaker and less direct.

How is it used? / Administration

Form: Sunflower-derived lecithin granules, softgels, or liquid (preferred over soy lecithin for allergen/non-GMO reasons)

Typical dose studied: 1,200–2,400 mg/day (softgel), or 1 tablespoon/day (granules)

Timing: With meals

Evidence for the clogged-duct use is thinner than most entries in this guide -- mostly survey/case-level, not RCT-grade. Be honest about that evidence gap in the display copy rather than overstating it.

? Emerging / limited evidence

Who should avoid it?

Already taking it? Generally well tolerated; mild GI upset (loose stools) possible at high doses.
