Youtheory Spore Probiotic (60 Capsules)
by Youtheory
"Spore-based probiotic — Bacillus strains that survive stomach acid and don't need refrigeration"
Overview
Youtheory Spore Probiotic uses Bacillus-based spore-forming probiotics that naturally survive stomach acid, heat, and shelf storage without refrigeration. Spore-based probiotics are fundamentally different from Lactobacillus/Bifidobacterium strains — they form protective endospores that remain dormant until reaching the intestines, where they germinate and colonize. This ensures nearly 100% survival through the stomach. The formula includes Bacillus subtilis and Bacillus coagulans.
