Proflora® 4R contains three of the most well-researched, sporeforming probiotics available. The subject of multiple double-blind, placebo-controlled studies, they have been shown to survive passage through the stomach and grow and thrive in the small intestine, germinating within hours after consumption.*

All three soil-derived Bacillus species are included in the Proflora® 4R formulation at evidence-based levels.

Together with the soothing botanical ingredients Marshmallow Root, Aloe Vera, and Quercetin, they offer something remarkable.* Shelf stability. Immunomodulation.* Survival through the GI tract. And the ability to help increase keystone species and restore microbial diversity, even in the presence of antibiotics.*
