Probiotics and Flu Shots: A successful combination

It’s that time of year when grown-ups and kids alike turn to sniveling scaredy cats as they face their annual flu shots. But our bravery is rewarded by all the benefits of getting that shot! And guess what. . . the probiotics you’re taking make the flu shot even more effective.

A study published in 2007 in Nutrition found that two weeks after the vaccination, natural killer cells were increased in the group of patients taking probiotics but not in the placebo group. (The probiotic strain taken by that group was in the Lactobacillus fermentum family.) The probiotic group also saw an increase in immunoglobulin A (an antibody, which is a large protein that fights foreign invaders in your body).

What this means is that the probiotic group saw their immune response ramped up — and over the next five months, that group got fewer flu-like illnesses.

The idea that probiotics make your flu shot more effective won’t make it hurt less when it’s administered. But at least you know that, teamed up with your probiotics, it’s going to really work to keep you healthy this winter!

Go with your gut,

The Probulin Team
