  1. Kelley Gold

    My physician recommned this probiotic to me.
    Happy with the results so far.

  2. Roisin L.

    I’ve read the book “Healthy Gut, Healthy You” by Dr. Ruscio (I’m also listening to his podcast!) and have been amazed to learn about all the functions our gut is related to.

    Afterwards, I looked for a probiotic supplement and chose this one because it’s:
    – organic
    – hypoallergenic (I had problems with other supplements in the past)
    – has 15 strains (as diversity is super important)

    Really good results so far, will buy again.

  3. Jeremy

    Good probiotic, does what I was hoping it would.

  4. Morgan Henderson

    As someone who has been suffering from various gut-related problems (bloating, stomach pain, etc.), I am really happy with the effect this product has on my gut.

    The pain has been reduced greatly and also the bloating is practically gone.
    I think especially the Bacillus coagulans strain is really good in this regard – I’ve read all the studies about it and therefore chose this product here.

  5. Stella Brown

    Only after reading a few books recently, I have understood how gut health really is for us!
    It seems like the gut is involved in a lot more than “just” digestion: brain function, metabolism, immune system – it’s all related to the gut apparently.

    Therefore, I started to take this more seriously and was looking for a good probiotic that could help me improve my gut health.

    I am very happy with Multi Bac in that regard – my digestion feels good and I also feel like I am thinking more clearly since I started taking it.

    Can definitely recommend it to others!

  6. Cassandra Brook

    This is the BEST probiotic I have ever taken!
    It’s all organic, has 15 strains and also a high dosis (20bn per serving).
    Love it!

  7. Erica (verified owner)

    Amazing stuff. I feel so much better on this stuff. I didn’t realize how much of a change a good probiotic could do for me.

  8. James H.

    Kaya has become my daily companion for the past few months. After being a bit skeptical at first, I must say that my gut health increased tremendously over the last few weeks. This impacts my general wellbeing far more than I would have expected. The bacteria seem to do what they are supposed to 🙂
