Pawtheory was designed to address the most common failure points of probiotics — without unnecessary complexity or hype.

A focus on survivability

Pawtheory uses spore-forming Bacillus strains, which naturally exist in a protected, dormant form. This allows them to:

• tolerate stomach acid
• remain stable on the shelf
• activate in the intestinal environment

Why spore-forming strains matter

Spore-forming probiotics are:

• more resilient during digestion
• less sensitive to storage conditions
• better suited for consistent daily use

This doesn’t make them “stronger” — it makes them more reliable.

Intentional formulation

Pawtheory is formulated with an emphasis on:

• functional strains, not filler
• stability over flashiness
• support you can use long-term

What this means in real life

A probiotic that survives the journey is more likely to:

• support stool consistency
• improve digestive resilience
• help the gut return to baseline more easily
• The takeaway

Pawtheory isn’t about adding more — it’s about designing better.
