For anyone interested in L. Reuteri, you can buy it in the U.S. as Gerber probiotic drops (https://medical.gerber.com/products/supplements/soothe-colic...). Marketed for babies but obviously works on adults too. Last I checked Gerber had an exclusive license on U.S. distribution of this bacterium—there’s a Swedish company, BioGaia, that IIRC is the original patent holder.
