Alleviate Flatulence

Lactic acid bacteria have been shown to inhibit the growth of pathogenic bacteria and their production of toxins and gas.^4,12,13,27 Variation in gas production and odor can be due to variations in resident bacteria in the intestinal tract^28-30. 

Taking lactic acid bacteria may have a twofold effect on gas production: 1) less hydrogen is produced in an acidic environment³¹ (friendly bacteria produce lactic and acetic acid, reducing the pH of the intestinal tract^4,6,7 and 2) some friendly bacteria may alter the preexisting flora and thereby alter gas production and composition²⁷. 

Antibiotics, by altering intestinal bacteria, have been shown to both increase and decrease gas production.²⁸ A pilot clinical study using Wakunaga's L. acidophilus and B. bifidum noted a decrease in flatulence in 42% or 15 of 36 subjects⁸.
