Good job

The smart belly probiotics are working well and my “belly” appreciates it

Smooth excrement

How do you know when you have the right probiotic? When your belly feels good and your bowels are snakes.

Great probiotic

Only been on smart belly probiotic for a short time but already can feel the difference.

Too soon to be sure

I don’t feel much difference.

Adult Probiotic

My stomach feels great and my emotions calmer!!

Great balls of poop!

This is the first time in my life that I have had a normal bowel movement. Thank you so much.

Not sure yet

They don't seem to be doing anything. I'm hoping I just haven't given them enough time. They were quite expensive so I hope my husband or I start seeing some results.

Great products

We use the kids daily, women's daily, men's daily and have just switched to the adult's daily - love these products!

So far, so good.

I have spent way too much money 'trying' and hours of researching these 'probiotic' formulas. I could write a book. But I won't! I'll just suggest to anyone reading this that they can stop their research here and now and buy these. No bloating, no 'windy' experiences and a proper evacuation of the lower track gently and daily. Thank you, Smart belly!!

I'm Happy

I have tried around 10 probiotic brands, This one seems to be working the best with my stomach issues, and skin issues. Is my second order, and it seems I'll be ordering more soon.

So far so good

Been taking less than a month - but seems to be working good. No apparent side effects.

Great probiotic

I have tried other probiotics in the past but this one seems to do the job

Great probiotic

I think these are the real deal. I have been taking these for a week and feel more energy and more purified.

It really works!

Great product at a great price!


I'm almost through with my first bottle so I'm going to give it a few more months as I have been having stomach issues for years and don't expect this to fix me in a few weeks. What I can say is that they are convenient because they don't need to be refrigerated and are easy to swallow. Will update.

mens daily

husband says they are working great. belly feels better!

Good product

Very satisfied.

Fantastic Product

I’ve suffered with chronic diarrhea for several years. Doctors could never find the problem. After speaking with my niece she stated she & her husband had the same issues til they started taking probiotics. I went online (I’m disabled & can’t get to a store) & after a lot of research I ordered Smart Belly. After the second day the “gurgling” in my intestines & the diarrhea stopped. I cannot praise this product highly enough.

Good so far

Hope it continues

Women's probiotic

I think these are working well, they are easy to swallow and can be taken with or without meals.

Smart belly

I have tried smart belly for less than one month and have already noticed I have less bloating and gas.

I have tried other probiotics and these seem to work best so far.

Good Product!!

I'm really not sure how to tell a probiotic works but I feel better and so does my system.
I will continue with this.

Great Probiotic

We're very happy with this probiotic. Convenient that it doesn't have to be refrigerated. Impressed with the Smart Belly website, too.

Good product

So happy I ordered some for my wife
