Best probiotic formula out there
Me and my family are helped tremendously by these probiotics. When they were out of stock we were taking 5+ different probiotics without a similar effect and were really frustrated with lots of gut issues. We were thrilled when these were back in stock as they are amazing and help our bodies as well as our pets bodies too.

Don't stop a good thing!
I've been taking this probiotic for nearly a year. I ran out for a few weeks and boy did I notice a difference this past week..... felt yucky in the tummy 🤢 !! Got onto the subscription plan for this so that never happens again.

Love this product!
I have been using Douglas Laboratories Multi Probiotic 4 Billion for a couple of years and can really tell a difference with my bowels. I recently, however, bought some on Amazon from a seller who sent me a bottle of the probiotic that did not look anything like the pills I was accustomed to seeing. So I returned the bottle. So be careful who you order this probiotic.

It worked from day one. No bloating.
Love how quickly it worked with noticeable results.
