Vogue's thoughts on the Smart Probiotic

"I've taken probiotics in the past and I only recently learned that most of them don’t undergo testing. This has and it actually works, all the good stuff goes straight to your gut."

SPB – Pill exploding

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.

SPB – Quality – bottle in delivery box with hand

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.
