Shipping and taxes calculated at checkout.
Two complementary functions. One daily formula.
Probiotics support the intestinal microbial environment. Digestive enzymes support the process of breaking down food. Bacillus B3 brings both into one focused formula.*
Three Bacillus species provide 9.9 billion combined CFU to support a healthy intestinal microbial environment.*
One formula. Three complementary layers.
A deliberately focused architecture built around probiotic support, digestive enzyme function, and a prebiotic component.
Three Bacillus species in a naturally resilient spore-forming probiotic format, formulated to support a healthy intestinal microbial environment.*
Amylase, protease, lipase, cellulase, and hemicellulase support normal breakdown of major food components.*
A dietary fiber commonly used as a prebiotic ingredient, included as part of the integrated formula.
Resilience is built into Bacillus biology.
Many conventional probiotic cultures are active living cells. Bacillus organisms can also exist in a protective spore state—a naturally resilient biological form well suited to shelf-stable probiotic formats.
Different probiotic organisms have different stability characteristics. Formulation, storage conditions, and strain identity all matter.
Metabolically active
- Common in conventional probiotic formats
- Can be environmentally sensitive
- Stability varies by organism and formulation
Protective dormant form
- Naturally resilient biology
- Well suited to shelf-stable formats
- Distinct from many conventional active cultures

Frequently asked questions.
What makes Bacillus B3 different?
Bacillus B3 combines three spore-forming Bacillus species, five digestive enzymes, and inulin in one daily formula. The formula is designed to support both normal food breakdown and a healthy intestinal microbial environment.*
How much probiotic is in each serving?
Each two-capsule serving provides a combined 9.9 billion CFU from Bacillus coagulans, Bacillus clausii, and Bacillus subtilis.
Why include digestive enzymes with probiotics?
Digestive enzymes and probiotics perform different but complementary roles. The five enzymes support normal breakdown of food components, while the Bacillus species support the intestinal microbial environment.*
What does spore-based mean?
Certain Bacillus organisms can exist in a naturally protective spore state. This biological form has a different resilience profile from many conventional active probiotic cultures.
Does Bacillus B3 need refrigeration?
The current product is labeled shelf-stable. Follow the storage directions printed on the finished bottle.
How long does one bottle last?
The serving size is two capsules and the bottle contains 30 servings. When used at one serving per day, that is a 30-day supply. Follow the finished product label or guidance from your healthcare professional.
