How do we stand out?
There’s a reason why standard probiotics don’t work.
Through testing best-selling probiotics, we found most contain less than 10% of the live bacteria promised on the label. And most will be killed by stomach acid before they make it to your gut.
So we created a probiotic you can trust. The Smart Probiotic delivers seven proprietary strains to your gut alive, using acid-resistant and double-capsule technology.
