Why AB22™ Is Different — and Better for You
EarthFirst Organic Probiotics feature Bacillus subtilis AB22™, a U.S.-grown, shelf-stable spore-forming probiotic unlike any other. While many strains lose potency in heat or stomach acid, AB22™ achieves over 99% sporulation, meaning it survives the journey through digestion and reliably reaches your gut—alive and active.
What makes AB22â„¢ stand out:
-
Microbiome Promoter – Boosts the growth of beneficial Lactobacillus and Bifidobacteria for a balanced gut.
-
Digestive Support – Produces natural enzymes that help break down proteins, carbs, and fiber for better nutrient absorption.
-
Gut-Brain Connection – Supports pathways linked to motivation, mood, and overall cognitive well-being.
-
Defends Intestinal Cells – Shown in lab studies to protect against environmental toxins like glyphosate.
-
Shelf-Stable Strength – Maintains potency without refrigeration thanks to its spore-forming resilience.
-
Whole-Body Benefits – Helps reduce occasional bloating, gas, and constipation while supporting immune health and healthy stress responses.
Every EarthFirst Organic Probiotic—whether 25B or 50B CFUs—delivers this next-generation strain, making your daily probiotic more effective, more resilient, and more aligned with nature.
