  • Effective Probiotics

    Posted by Christine on Mar 15th, 2016

    Have used Polyflora O for a number of years with effective results in regards to IBS issues plagued with since young adulthood. That in combination with following food list protocols have brought me into maintaining normal function for many years. I have forgotten I even had IBS at one time...except on the very rare occasion I step out and have ice cream

  • Amazed

    Posted by Penny on Mar 4th, 2016

    This has worked the best than any Probiotics we have tried for our type O family. Promotes regularity and wards off constipation, stomach bloating banished and has helped our bodies ward off illness when others around have been sick. Polyflora is an essential part of our family's daily nutrition.

  • Poly Flora Just makes Sense

    Posted by Nancey Kinney on Feb 18th, 2016

    Since we fall into blood type and geno type groups it makes sense that our good bacteria are not all the same either. Love the distinction of the PolyFlora.

  • Probiotics for blood type make sense

    Posted by Nancey Kinney on Jan 12th, 2016

    So many competitors, but epigenetics count not billions or millions of good bacteria, but the right one for your type.

    Per my review of 2014, I take this with Live Cell (I forgot to mention this in my review of a few minutes ago).
