I like the fact that I almst never catch anything that is going around. The SBO’s don’t just prevent illness. The gut and the bacteria it contains are a major organ of the body, and is essential for ongoing general good health. I don’t know if there is any way to precisely quantify the effectiveness of the system, though. I usually read Dr. Mercola’s webpages for information, because he is continually studying, himself. I recommend it for the information it contains.
Thank you!
