Carrageenan
Approved as safe by regulators, though some researchers have raised questions about gut effects. Normal amounts in food aren’t a known risk; people with gut issues may choose to limit it.
Lecithin
Generally safe. It is an emulsifier usually made from soy or sunflower; the main thing to check is soy if you are allergic.
