Lecithin is used in food to provide a smooth, moist texture and to keep ingredients from separating. Lecithin can naturally be found in green vegetables, red meat, and eggs. Commercial preparations are often made from soybeans, egg yolks, or animal products. It is also commonly used in eye drops, skin moisturizers, and food emulsifiers (agents that keep ingredients from separating).

Sunflower lethicin, a specific kind of lethicin, is often taken during breastfeeding to reduce plugged ducts or to help increase milk flow. Sunflower lethicin is thought to reduce the “stickiness” of breast milk by thinning out the fats in the milk and keeping them from clumping together. There are no known contraindications for breast-feeding, and lecithin is “generally recognized as safe” by the FDA. However, people with a preexisting tendency to depression may become depressed if taking high doses of lecithin. While very rare, if you begin to have a fish-like odor while taking high doses of lethicin, stop taking it immediately and notify your physician, as this is a serious sign of liver damage. As there is no recommended daily allowance for lecithin, there is no established dosing for lecithin supplements. Different brands might have different amounts of lecithin in each pill or capsule, so be sure to read labels very carefully before taking lecithin or any other dietary supplement. Per Kellymom.com, the maximum dosage recommended for recurrent plugged ducts is 4,800mg/day. As always, consult with your doctor before trying any dietary supplements while pregnant or breast-feeding.
