Probiotics in capsule form


Probiotics are live bacteria and yeasts that are considered beneficial to the body’s overall health. Clinical research shows that regular probiotic use supports a healthy digestive system and helps with occasional gas and bloating.1* In addition, a growing body of evidence suggests that probiotics play an important role in supporting healthy immune function.2*

Properties and mechanism of action

While research into the molecular mechanisms of action of probiotics is ongoing, some of their functions include3:

  • Colonizing intestinal microbial communities*
  • Supporting balance of fecal enzymatic activities*
  • Producing short-chain and branched-chain fatty acids*
  • Producing cell adhesion and mucin*
  • Supporting the immune system*

Scientific support

Three specific probiotic strains have been well studied for their digestive and immune benefits:

Bifidobacterium breve is a gram-positive bacterium which is one of the first colonizers of the infant gut. B. breve strains have been well studied in infants, demonstrating that:

  • A 3-month treatment with B. breve strains in healthy newborns helped to reduce daily vomit frequency, decrease daily evacuation over time, and improve stool consistency4*
  • Administration for 3 months of 2 B. breve strains (B632 and BR03) helped to restore the gut microbial balance5*
  • When used daily for 3 months, B. breve significantly reduced crying time in babies due to gas or occasional stomach upset6*

Bacillus coagulans is a gram-positive, spore-forming bacterium with high survival tolerance to acid and bile conditions. It has been extensively studied in both babies and adults, demonstrating that B. coagulans:

  • Increases nutrient absorption and availability, in cooperation with gut microbiota2*
  • Supports key aspects of innate immune defense mechanisms7*

Bacillus subtilis is another gram-positive bacteria that can survive extreme conditions, which has been studied in children and adults for over 40 years. B. subtilis has been demonstrated to:

  • Survive transit through stomach hydrochloric acid8*
  • Support immune function and improve gut health9*
