According to the study published in Clinical Nutrition, HOWARU® Protect Sport was shown to delay the time of respiratory tract illness and increase physical activity in physically active adults.

A study conducted in Australia by the Griffith Health Institute at Griffith University and the Australian Institute of Sport measured the effect of daily consumption of the probiotic combination Bifidobacterium lactis Bi-07™ and Lactobacillus acidophilus NCFM® , known commercially as HOWARU® Protect Sport, on more than 300 healthy, physically active men and women over a 5 month period.

A significant delay in the onset of Upper Respiratory Tract illness was observed among the subjects. There was a significant delay in the median time to an episode of illness in the HOWARU® Protect Sport groups compared to the placebo groups (placebo 2.5 months; NCFM® Bi-07™ 3.4 months). The most notable finding was a significantly higher level of physical activity compared to other subjects in the trial, who were taking HOWARU® Protect Sport (extended exercise duration by 0.5 hours, training load by 9% per week).
