39 Customer Reviews Write a Review

Personalized probiotic with flora specifically beneficial for Blood Type A. Also includes prebiotic synergists to strengthen digestive health.

Select your blood type: O A B AB

We've personalized probiotics.

Studies have documented the clear role our ABO blood type and secretor status play in determining the makeup of our microbiome—the total population of bacteria that live within our digestive tract. Because the foods you eat react chemically with your blood type, personalizing both your food, with The Blood Type Diet, and your supplements, with the probiotics and prebiotics in Polyflora A, will allow your body to support healthy digestion.

Probiotics are acid bacteria organisms and cultured food products that support healthy intestinal balance of the microbiome. Prebiotics are nutrients that help support growth of healthy intestinal flora. Our personalized formulation of probiotics and prebiotics support your digestion.

Dr. Peter D'Adamo's revolutionary Polyflora A is a personalized probiotic with flora specifically beneficial for Blood Type A, plus prebiotic synergists to strengthen digestive health.

  • Supports the healthy intestinal balance of the microbiome
  • Strengthens digestive health
  • Promotes overall gut health using specific strains deemed beneficial for Type As

Our exclusive Polyflora A combination includes:

Bifidobacterium bifidum
Acts as a protective bacteria, promoting a diverse gut microbiome. A key species to populate the intestinal tract, B. bifidum is one of the first commensal bacteria to populate our intestinal tracts in infancy.

Lactobacillus plantarum
Supports weight management and is shown to support and modulate the immune system as well.

    It’s great

  • polyflora A

    I thought it would be more "fresh" or "alive". Do you have a produce with more live cultures? Could be more effective, I'm not sure why. I expected a lot from this product......

    They are the best and work so well for us.

  • Good Product

    My body consistently tests strong for this product.

  • This Product Is Amazing!

    I Have Used Many Probiotics And This One Is The Best For Me!

  • Great probiotic!

    Posted by Christy on Jan 19th, 2018

    I take just one dose a day(because I’m forgetful), but it does the trick. I have less stomach upset than I’ve had in a long time also. I think my previous probiotic had some ‘avoids’ in its formula. I like having a probiotic tailored to my system.

  • Still my number one.

    Posted by Mariarosaria M. on Jan 17th, 2018

    After so many years Polyflora is still my number one probiotic. I have tried others these last years based on more info from Microbiome discovers. We all know now how good bacteria are important for our health, and when I did find out that the main strains for cardiovascular are in this probiotic I did realize why Dr. D'Adamo created for blood type A.

  • Best probiotics!!!

    Posted by Anonymous on Nov 1st, 2017

    This by far the "Best" probiotics

  • Probiotics A

    Posted by Carl Rossetti on Sep 5th, 2017

    I use Peter's because I trust him and his programs. I don't know how well they work compared to other brands, because I've only used his since I started this new life style back in 2001. Thank you Peter!

  • Daughter's constipation gone!

    Posted by Bettie Adams on Jun 15th, 2017

    Daughter not a believer....yet. Took advise to try this product when having problem. Reported back to me that it had worked with no problems or side effects. I now stock it as my naturopath recommended to take a probiotic anytime I get sick.

  • The Best

    Posted by Randy Gold on Dec 23rd, 2016

    This is by far the best probiotic I've ever taken, it works like a dream. My 92 year old father is the same blood type that I am, so I had him try it and now he swears by it and takes it everyday!

  • The Best Probiotic

    Posted by Anonymous on Oct 29th, 2016

    I've been taking my Polyfloa A continuously for about 6 months now and I have to wonder where it was my whole life?! For the first time EVER I'm "regular" and being "regular" feels soooooo good!!! I've tried other probiotics and nothing else worked as gently or simply. I won't be without it now!
