World's most studied strains. Fact.
Designed by neuroscientists, dietitians, and gut experts over two years, the Smart Probiotic represents an unmatched commitment to research.
Our strains are backed by over 380 clinical studies, and we’re continuously investing in third-party testing so you can trust what you’re putting in your body is proven to work.
Designed to survive
Most probiotics don’t work—the bacteria die before they reach the gut.
But our delayed-release technology and proprietary protective matrix guarantee the majority of our 20bn CFUs reach your colon, where they can have an impact.
Engineered with precision
From strain-specific fermentation to continuous temperature checks, every stage of the Smart Probiotic’s manufacturing process is carefully monitored.
That’s why it contains 200x more live bacteria than best-selling over-the-counter alternatives.
