Don’t take licorice during pregnancy (not sure you were asking about that but wanted to make sure. :0) )
The leaky gut formula will work fine without the licorice. If you don’t want it, just take it out. That said, the leaky gut protocol isn’t forever and I don’t think the licorice at those levels for that amount of time will bother estrogen levels.
Don't use herbs or combine herbs with medications or use them during lactation or pregnancy without talking with your healthcare provider.
