The Dirty Secret of the Supplement Industry
Your stomach is a furnace. And most supplements are sending bacteria straight into it - unprotected.
When you swallow a standard vegetable capsule, it dissolves in your stomach within 15-20 minutes. It dumps those delicate, living organisms straight into a
pool of hydrochloric acid.
“Up to 96% of standard live cultures die upon contact with stomach acid.” 1
You're paying for "50 Billion" cultures, but 48 Billion of them are dying before they ever reach the intestines - the only place they can actually work.
You're paying for expensive dead bacteria.
We Didn’t Need Better Bacteria. We Needed a Better Vehicle.
Introducing Duocap® Technology - a revolutionary "Capsule-in-a-Capsule" delivery system backed by 3 clinical studies.

Good bacteria multiplies in the intestines with FOS
The result?
Cultures arrive alive, awake, and surrounded by their food source. They don't just survive - they thrive immediately.

ABOUT THE INGREDIENT
Streptococcus thermophilus ST-21 is a bacterial strain commonly used in the fermentation of dairy products.
It produces lactase, an enzyme involved in the breakdown of lactose, the natural sugar found in milk and other dairy foods. 1
This enzymatic activity contributes to the conversion of lactose into simpler sugars during digestion.1,2

Rhowell®
Capsule technology
Standard gelatin - dissolves quickly in stomach acid
Duocap® double-capsule - HPMC material for delayed, protected release
Number of strains
Often 10-20+ strains competing for limited space and resources
4 specifically selected, complementary strains with meaningful amounts of each
Fiber substrate
Usually none, or mixed in the same capsule
FOS included in outer capsule for separated, timed release
Delivery timing
Everything releases at once in the stomach
Staged release. Fiber is released first, bacteria later
Storage requirements
Many require refrigeration
Shelf-stable - no refrigeration needed for product stability
Formula approach
More strains = better (marketing logic)
Fewer, better strains = less competition, more survival (engineering logic)
