Real Probiotics that Really work!
I take this probiotic daily paired with Intestinal Fortitude's GLR-6 gut lining repair with only great results. If you need a good probiotic daily then leave the "probiotic" yogurts in the store and opt for this option that is a REAL probiotic to help your digestive system operate at it's best potential. I recommend and will continue to purchase this product.

Really Helped My Gut
I've been a happy consumer of Intestinal Fortitude products for awhile now, which have helped me manage celiac disease complicated by other autoimmune issues. I was really disappointed when their discontinued their old probiotic a few months ago, but this new version is even better. When taken in combination with the prebiotic and other IF products, my inflammatory markers are next to nothing. Thank you Intestinal Fortitude!

Not much change
These capsules are really easy to swallow they're not huge. There is no taste, and you can take them anytime of day. I really didn't notice any difference, maybe a little more regular in the bathroom so that would be better gut health but I can't say that it has a lot of health benefits that I've noticed. I have used the whole bottle. It's a good value if it does help you.

Waste of money
Was taken it for a month, and no result or any reaction, can’t return, real probiotics should be refrigerated only they can actually help, don’t waste your money. I am taken their other product stomach lining repair and it’s not doing anything either. I still have problems going to the bathroom, no help with digestion whatsoever.
