    I was not sure about taking a probiotic because I have taken them in the past without seeing much difference but this one seems to have helped with my digestive issues. Am continuing to take it as it seems to make a difference.

    Loving the fact I can trust the supplements are truly Gluten free. I’m beginning to feel much better one month into being on the true gluten free approach 😁👍👍

    I had to stop taking Biotic Defence 3 weeks prior a test that my doctor ordered. I never realized how much they helped my gastro-intestinal issues. I’ll never go without them again!

    I love this product, the S. Boulardii in this product seems to work best for me, I do alternate them though.

  7. Sharon N.

    I take this one per Dr.Osborne and it has mard a big difference in bloating. I forgot a few times to take and that showed me what a big difference it was making. I am so pleased that all of his supplements are grain free. I trust his suggestions completely.

    I had to take an antibiotic. I feel that S Boulardi is definitely repopulating my digestive tract with good bacteria.

    I have never really taken a probiotic for my gut. Now being older I realize we need probiotics. I have been listening to Dr. Osborne for a while now and had decided to take the steps of taking a probiotic. It has helped me with my stomach issues tremendously. Of course with eating my proper and correct foods. Thank you for all your hard work in helping us all who don’t know where to start.

  15. Elaine P.

    This is the best probiotic I’ve taken. Seeing great results in my stomach and gut!!!
    Thank you Dr. Osborne for such amazing product

  16. Quieta B.

    Wonderful to find this supplement with no bad ingredients!


    I’ve been taking Biotic Defense for over a year, along with Ultra Butyrate. This proved effective in a very short time frame. I have continued to use it for 4 weeks, then switch it out with Ultra Biotic Defense.
    Working to heal intestinal permeability takes time, but the changes are noticeable. It has been a relief to have access to supplements that I can trust. No downsides to using Biotic Defense — the integrity & quality are unsurpassed.

  18. Lavena F.

    It is a very good product. I love the fact that you don’t need to worry if it is a good product. All are great.

  19. Susette H.

    This probiotic works better for me than the other probiotic.
