Probiotic yogurt reduces cold symptoms
Effect 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.

Probiotics reduced cold symptoms
Randomized controlled trial of probiotics to reduce common cold in schoolchildren.
Study shows significant effectiveness.
We assessed the impact of a two-strain probiotic, Lactobacillus acidophilus and Bifidobacterium bifidum, on common cold symptoms in schoolchildren through a double-blind randomized controlled trial.

Over three months, children aged 8-13 in Thailand received either the probiotics or a placebo.

We found a significant reduction in cold symptoms and school absenteeism among those taking the probiotic, along with lower rates of fever and cough. Overall, this suggests probiotics could be beneficial in managing cold symptoms for school-aged kids.

L. lactis may reduce cold risk
Immunomodulatory effect of Lactococcus lactis JCM5805 on human plasmacytoid dendritic cells.
High relevance to immune support
We conducted a randomized, placebo-controlled study to examine the effects of Lactococcus lactis JCM5805 on common cold immunity. Our findings showed that this probiotic activated human plasmacytoid dendritic cells, which are key players in fighting viruses.

Participants who consumed yogurt fermented with L. lactis JCM5805 experienced a reduced risk of getting colds compared to those in the placebo group. This suggests that L. lactis may enhance our body's anti-viral defenses.

Overall, it looks like incorporating L. lactis into our diet could be beneficial for boosting immunity against the common cold.

Freshness vital
This is a great product. Be cautious with shipping if you live east of the Mississippi — I recommend overnight delivery to maintain its freshness, as it greatly impacts effectiveness against issues like the common cold.

Improved immunity
It seems suitable for me. I have been drinking it for less than a month, twice in the morning and evening, and my stomach has greatly improved. I believe my intestinal health has enhanced, and I find it harder to catch a common cold.

Probiotics effectively reduce cold symptoms
Probiotic effects on cold and influenza-like symptom incidence and duration in children.
Study highly relevant to childhood health
We examined the effects of Lactobacillus acidophilus on cold symptoms in young children. In a double-blind, placebo-controlled trial, 326 children ages 3-5 received either probiotics or placebo for six months.

The results were promising: children taking probiotics had significantly fewer instances of fever, cough, and runny nose compared to those on placebo. They also missed fewer school days and required less antibiotic treatment.

Overall, probiotics proved to be a safe and effective method for reducing common cold symptoms in children.

Probiotics may lessen cold symptoms
Effect 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.

Probiotics reduce cold illness in children
Probiotic effects on cold and influenza-like symptom incidence and duration in children.
Highly relevant findings on probiotics.
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.
