Replenish Microflora with Primadophilus Optima

Primadophilus Optima is the most potent (35 billion CFUs) and diverse (14 strains) delivery of probiotics for intestinal microflora.

Why 14 Probiotic Strains?

  • Like a fingerprint, each individual has a unique balance of strains in their microflora
  • Primadophilus Optima provides a broad diversity of strains commonly found in the human digestive tract

Plus NutraFlora scFOS

  • Unique "short-chain" form of FOS
  • Preferred food source for microflora
  • Promotes microflora growth & colonization

Importance of Microflora

The "friendly" bacteria of the intestinal tract are essential to good health because they:

  • Secrete enzymes to aid proper digestion
  • Produce organic compounds that inhibit the reproduction of harmful bacteria
  • Boost immune function

Stress, poor diet, antibiotic use and bouts with diarrhea adversely affect microflora.

No Effect

Posted by iHerb Customer on Feb 12, 2018 | Verified Purchase

Taken it for about 1 month but do not see any improvement. A pity that it doesn't work for me. I have been trying many brands and there is 1 brand that works much better for me so I will be sticking to that brand. It is quite an expensive probiotics so I am quite disappointed

Thanks for your feedback!

Super probiotics! 14 bacterial strains!

Posted by iHerb Customer on Oct 28, 2014 | Verified Purchase

I ordered Primadophilus cause I suffered from a bad case of intestinal candida. This product helped a lot rebalance the normal gut flora. 14 strains of probiotics is an excellent number!

Thanks for your feedback!

Ice Packs

Posted by iHerb Customer on May 16, 2012 | Verified Purchase

I received my product pretty fast without the ice pack. However, I just noticed on Luckyvitamin dot com that they state product is temperature sensitive and they ship with ice pack just like the way they receive the product from the manufactuer. Now I am worried my product is weak or no good. I went to manufactuers web site and did not see any info written that it was ok to send without ice pack. I have contacted their customer support under FAQ link to verify if ok to ship without ice pack. Big price difference too $27.31 vs $37.48. http://www.naturesway.com/Products/Probiotics/15783-Primadophilus-Optima-High-Potency.aspx http://www.luckyvitamin.com/p-11301-natures-way-primadophilus-optima-60-vegetarian-capsules UPDATE: I just received response back from Natures Way customer support. They validated info iherb states...ok to ship without ice pack. They also re-stated the following: "Primadophilus can be out of refrigeration for a few days without losing the potency. We add extra cultures to allow for the product to be out of refrigeration for shipping and manufacturing. But for maintaining the potency through the expiration date the product should be stored in the refrigerator."
