Probiotic G.I. provides 10 billion CFU per capsule of the beneficial bacteria *Lactobacillus acidophilus* , *Lactobacillus salivarius* , *Lactobacillus casei* , *Bifidobacterium bifidum* , *Bifidobacterium lactis* and *Streptococcus thermophilus* . Beneficial microflora are crucial for proper gut-associated lymphoid tissue (GALT) function and development.1 The GALT helps protect intestinal mucosa from allergens and toxins and is a major component of the body's immune system.2 It is estimated that more than 70% of the body's B lymphocytes are found in the GALT. Probiotics are believed to support healthy GALT composition, and in turn, support barrier function, G.I. epithelial cell health and T cell function within the G.I. tract.3 Some probiotic strains may also modulate local production of cytokines and other immune mediators in the G.I. epithelium.4 Research suggests that *Lactobacillus salivarius* (Ls-33), *Bifidobacterium lactis* (Bl-04) and *Streptococcus thermophilus* (St-21) help to maintain healthy immune mediator balance.5-7
