Irregularity and Probiotic  Yogurt Slow intestinal transit is not necessarily pathologic and corresponds to the upper limit of normal transit time: approximately 48 to 72 hours, but it can be as long as 120 hours. Transit time exceeding 120 hours is generally diagnosed as constipation.2


Slow intestinal transit or occasional irregularity may be a source of daily discomfort and the physical and psychological consequences on the quality of life should not be underestimated.

How can Activia help? Two double-blind, randomized, placebo-controlled studies show the effect of Activia on helping with occasional irregularity.3,4 These studies were designed to investigate the effect of Activia on reducing transit time.

Activia makes probiotic yogurts and smoothies that contain the exclusive culture Bifidus Regularis, which has been proven to survive passage through the gastrointestinal tract in sufficient numbers for Activia to have its beneficial effects.

Activia helps with occasional irregularity when consumed 3 times per day for two weeks as part of a balanced diet and healthy lifestyle.

Activia may help reduce the frequency of minor digestive issues like bloating, gas, discomfort and rumbling, when consumed twice per day for two weeks as part of a balanced diet and healthy lifestyle.
