Back in January of this year (2019), a friend of mine asked if I would try making a specific type of yogurt called L. Reuteri, that Dr. William Davis (author of Wheat Belly) recommended. There had been a posting about the amazing health benefits that stemmed from a probiotic called BioGaia Gastrus, which is made with a specific strain of Lactobacillus Reuteri ATCC PTA 6475.
