Bests & Worsts Reviews from Amazon

I started seeing positive results from taking this supplement within about a week. After trying countless probiotics and other strategies to help improve my gut, I finally found something that actually works! My digestion in general has improved markedly. MY BACKGROUND: I've had a variety of digestive issues for decades, and though I've tried many probiotics, I've always had only either temporary or less than optimal results. I've always wondered why I've had to take tons of probiotics just to maintain a semi-normal digestion pattern and I think I figured out why: my gut environment has not been hospitable to the good bacteria that I'm ingesting -- i.e., the probiotics that I've been taking simply don't stick around. This is because I've had (I believe) an unhealthy presence of bad bacteria (probably due to stress and a somewhat weak digestive system) which has made it difficult for the good bacteria to optimally establish in my system. HOW THIS PRODUCT WORKS: This is a prebiotic meaning it is a product meant to create a better gut environment in which good bacteria (that promote better digestion) can establish themselves and flourish. There many different types of prebiotics, but this one deals with (a relatively new?) science that uses bateriophages. Bacteriophages are viruses that attach themselves to the cell wall of certain bad bacteria and disable them. The bacteriophages in this product (particular strains of myoviridae and siphoviridae) then release the nutrients in the bad bacteria in your gut, which feeds the good bacteria. In short, they help your good bacteria by eliminating its competition (the bad bacteria) and promoting an environment in which they can grow. SAFE? It appears safe to me. Bacteriophages in general are actually extremely plentiful in the world -- in soil, sea water, and intestines of animals. Bacteriophages have been used since at least the early 20th century to combat certain bacterial infections. It appears that more research has begun recently to more precisely determine the role bacteriophages have in human health (there aren't many studies currently, but scientific interest in this area appears to be growing). As to why it may be something our bodies actually need supplementation of, perhaps it has something to do with our food production process -- how we treat our soil and water and process our food -- that eliminates much or all of the beneficial bacteriophages that we would otherwise naturally consume. I'm not sure if this is true, it's just a theory of mine. Either way, I'm going to continue taking this supplement. UPDATE (June 2020): You may also want to look at Dr. Tobias's Deep Immune. It contains the same prebiotics in the same dosage as this product, but it also contains 4 billion probiotic bacteria. It's a great combination that I've used for years.
