Probiotics boost immunity, reduce coldsProspective study of probiotic supplementation results in immune stimulation and improvement of upper respiratory infection rate.
Relevant study on cold treatment.
We examined how probiotic supplementation influences the frequency of common colds in adults with a past history of multiple infections. In a carefully designed study where participants were randomly assigned to receive either a probiotic drink or a placebo, we observed that those taking probiotics had fewer upper respiratory infections and less severe flu-like symptoms.
Additionally, there was a notable increase in immune markers among the probiotic group, demonstrating enhanced immune function. However, certain immune indicators showed no significant differences between the groups. Overall, our findings suggest that probiotic drinks can be a safe option for reducing cold occurrences and boosting immunity.

LcS reduces cold occurrenceDaily intake of fermented milk with Lactobacillus casei strain Shirota reduces the incidence and duration of upper respiratory tract infections in healthy middle-aged office workers.
Highly relevant findings supported
We observed the effects of fermented milk containing Lactobacillus casei strain Shirota on upper respiratory tract infections (URTIs) among 96 healthy office workers aged 30 to 49. In a randomized controlled trial, participants consumed LcS-FM or control milk daily for 12 weeks. Results showed a significant reduction in URTI incidence in the LcS-FM group (22.4% versus 53.2%), along with fewer episodes and shorter duration of symptoms. This suggests that Lactobacillus casei may support immune health, helping fend off colds.

Probiotics may lessen cold symptomsEffect of Lactobacillus gasseri PA 16/8, Bifidobacterium longum SP 07/3, B. bifidum MF 20/5 on common cold episodes: a double blind, randomized, controlled trial.
Study shows moderate relevance
We investigated whether daily probiotics, specifically Bifidobacterium longum, could help lessen the severity and duration of common cold symptoms over a three-month period.
In a well-structured study involving 479 healthy adults, we compared those taking probiotics with a control group. Our findings showed that the probiotic users experienced shorter cold episodes—by almost two days—and reported less severe symptoms, with clear improvements in their immune cells.
Overall, it seems that Bifidobacterium longum could offer a valuable aid in combating common colds.

Probiotic yogurt reduces cold symptomsEffect of fermented milk on upper respiratory tract infection in adults who lived in the haze area of Northern China: a randomized clinical trial.
High relevance due to health insights
We investigated how consuming Qingrun yogurt, which contains the probiotic Bifidobacterium lactis, affects common colds among adults living in hazy areas. In a clinical trial with 136 participants, those who enjoyed the probiotic yogurt daily experienced fewer colds and reported milder symptoms compared to those who consumed regular yogurt.
Remarkably, it even shortened the duration and intensity of respiratory infections. The findings suggest that incorporating probiotic yogurt into our diets could be a beneficial strategy to help combat upper respiratory infections.

We evaluated the effects of probiotic consumption on cold symptoms in healthy children aged 3 to 5 during winter. In our double-blind, placebo-controlled study with 326 participants, we found that those who received probiotics experienced a significant drop in fever, cough, and rhinorrhea incidence.
Specifically, the combination of Lactobacillus acidophilus and Bifidobacterium lactis significantly reduced fever by up to 72.7% and decreased cough incidence by 62.1%. Additionally, children on probiotics missed fewer days of child care, making it a promising strategy for managing cold symptoms in young kids.

User Reviews
It's simply the best probiotic. I had various digestive issues and frequent common colds until I discovered Jarrow Formulas. I seldom noticed any benefits from multiminerals. Now, I take a course once a year in spring and feel fantastic.
I absolutely love this product! It has kept me healthy for two and a half years without catching even a common cold. The price keeps me coming back.
I suffered from diarrhoea due to chronic IBS and nothing worked until I tried this probiotic. It was a miracle! I always take four tablets when I feel unwell and plan to keep buying it.
I order probiotics from different brands for my family regularly. Jarrow Formulas is one of the best in effectiveness and value. They regulate digestion and boost immunity; we’ve noticed fewer common colds since starting this.
I recommend buying these probiotics in the cold season to ensure the bacteria are alive. I use them to make healthy kefir, which is a great treat!
