Carrageenan

Carrageenan is a natural thickener derived from red seaweed, used in dairy products, nut milks, and processed foods. For breastfeeding mothers consuming it in food, the amount that could transfer to breast milk is negligible. It is FDA-approved for use in food. The controversy around carrageenan mainly concerns its use in infant formula, which is separate from maternal consumption.

Always confirm with your doctor or lactation consultant before making dietary changes while breastfeeding.
