Microbiome Labs RestorFlora Most probiotic supplements rely on vegetative bacterial strains that are fragile — sensitive to stomach acid, heat, and the conditions of the digestive tract before ever reaching the gut where they are supposed to work. RestorFlora takes a different approach, using exclusively spore-forming organisms that survive transit intact and arrive in the intestines viable and ready to colonize. The formula combines three well-researched strains: Saccharomyces boulardii, a probiotic yeast with an extensive track record for supporting gut balance during and after antibiotic use and periods of digestive disruption Bacillus subtilis HU58, which produces beneficial compounds that competitively crowd out less favorable organisms Bacillus clausii SC109, known for its resilience and immune-supporting activity in the gut. Together they address both the restoration of healthy flora and the suppression of disruptive organisms — which is why this is a go-to during gut protocols, travel, antibiotic courses, or any period of microbial disruption. Because the strains are spore-based, the formula is shelf-stable and requires no refrigeration. Capsules can also be opened and mixed into food or non-carbonated beverages. 60 capsules | Shelf-stable | Vegetarian capsule | Free from common allergens These statements have not been evaluated by the Food and Drug Administration.
