While living in Goa, India, I have taken oral probiotics for several years and I always had the impression that it furthered my digestion. In younger years I had a tendency towards obstipation. Back in Germany I did not continue because probiotics with many different bacteria were far more expensive and anyway I developed a more pronounced program of supplements. I ordered some expensive probiotics, also sporebased probiotics, but I did not notice any positive effect. Nowadays, I stick to yogurt on a daily basis. I buy bio-quality in a glass. That seems to work quite well. Thank you for your interesting writing, always a pleasure.
