Taking probiotics may help reduce the impact of flu-like sickness
On average, people miss 1.7 days of work due to flu-like sickness.2
Flu-like sickness is common and places a burden on families & societies
Flu-like sickness usually includes a fever of at least 100°F (37.8°C) and a cough or sore throat.3 It is estimated that the average number of symptomatic cases in the US is 33 million/year.4
Flu-like sickness is common and can be severe. Even with the costs of hospitalization excluded, flu-like sickness places a substantial burden on families, societies, and economies due to the costs associated with visiting the doctor’s office, medicine prescriptions, and loss of productivity in the workplace.5

Probiotics may reduce the rate of flu-like sickness
More and more evidence suggests that probiotics support respiratory health, which helps lower the incidence of flu-like sickness.6, 7, 8 Several clinical studies have demonstrated the beneficial effect of the Lactobacillus rhamnosus, LGG® and Bifidobacterium, BB-12® probiotic strains (hereafter referred to by use of the trademarks LGG® and BB-12®) on the incidence, symptoms and duration of flu-like sickness.9, 10, 11, 12
Flu-like sickness symptoms include a runny nose and sore throat and are typically caused by respiratory tract infections.
The LGG® and BB-12® strains are associated with fewer symptoms and less days away from daycare
In clinical studies, daily intake of LGG® has been associated with a significant effect on:
• The number of children with upper respiratory tract infections11
• The number of respiratory tract infections lasting more than three days10, 11
• How long respiratory symptoms last11
• The number of digestive system issues lasting more than two days10
Also, healthy children supplemented with LGG® had significantly fewer days away from daycare due to illness, compared to the placebo group.11 Read more about LGG® and probiotics and respiratory health
A similar effect was seen in adults.9 Healthy college students who received a combination of the LGG® and BB-12® probiotic strains for 12 weeks had 33% fewer days with symptoms of respiratory tract infection. Their symptoms were also less severe than those who received a placebo.9 Read more about BB-12® and supporting immune health with probiotics
Probiotics may help limit the use of antibioticsResults from a 2019 study suggest that consuming probiotics can help to reduce the costs associated with flu-like sickness.1 The health economics study spanned five years and demonstrated that, in the US alone, the use of probiotics was associated with reducing the annual number of sick days by over 54 million.1 Interestingly, the study suggests that the use of probiotics could help avoid approximately 2.2 million courses of antibiotics per year.1 This means that 1 in 3 of all US antibiotic prescriptions could be unnecessary, suggesting probiotics might help avoid the overuse of antibiotics.
Probiotics may have benefits for our health and the economy
The studies discussed suggest that if everyone living in America consumed probiotics, the incidence and costs of flu-like sickness would be significantly reduced. Therefore, supplementing with probiotics may not only be beneficial to health9, 10, 11, 12 but might also reduce the impact that flu-like sickness has on families, economies, and societies.1
