Yeast supplement reduces cold symptoms
Effects of a modified yeast supplement on cold/flu symptoms.
High relevance to cold treatment
We explored the effects of EpiCor, a dried Saccharomyces cerevisiae fermentate, on cold and flu symptoms among healthy individuals who had recently received a flu shot. Over 12 weeks, we conducted a randomized, double-blind, placebo-controlled trial with 116 participants who took either EpiCor or a placebo.

Those supplemented with EpiCor reported significantly fewer symptoms and a shorter duration of illness compared to those on the placebo. This suggests that EpiCor may offer a beneficial approach to reducing cold and flu-like symptoms.

Yeast postbiotic reduces cold symptoms
Efficacy of a yeast postbiotic on cold/flu symptoms in healthy children: A randomized-controlled trial.
Highly relevant to pediatric health
We examined the effectiveness of EpiCor, a yeast-derived postbiotic, on cold and flu symptoms in children. In a randomized controlled trial involving 256 kids aged 4-12, we compared those receiving EpiCor with a placebo for 84 days during flu season.

Results showed that children taking EpiCor experienced less severe cold and flu symptoms and used fewer medications than those on the placebo. This suggests that EpiCor can enhance immune function safely, providing a helpful option for managing colds in children.

Yeast supplement shows potential benefits
Immunogenic yeast-based fermentate for cold/flu-like symptoms in nonvaccinated individuals.
Relevant score indicates research need
We conducted a comprehensive 12-week study to see how a daily yeast-based supplement, specifically Saccharomyces cerevisiae, affects people without recent flu vaccinations. In our randomized, double-blind trial involving 116 participants, those receiving the supplement noted improvements in cold and flu-like symptoms.

While promising, it's essential to highlight that more research is necessary to establish its effectiveness across broader groups. The initial results suggest that this nutritional supplement could offer a safe way to help those prone to these common illnesses.

Family lifesaver
This drug is a lifesaver for our family; I try to always keep it stocked. We use it for common colds, especially before and during trips when pathogenic flora is likely to take over. It has always provided effective relief for our whole family, particularly after consuming high-carbohydrate foods for extended periods.

Removes pathogenic flora
An excellent remedy for common colds, candidiasis, and poisoning, these probiotics effectively remove pathogenic flora from the body. I highly recommend them for anyone looking to improve their health!

Prevents family illnesses
I took these on the recommendation of a doctor friend during cold and virus season and gave them to my children. Normally, we all get ill together, but this time common colds bypassed us. I also administered it to my parents and elderly grandmother. We will certainly take another course soon.

Baker's yeast supports immune function
Baker's yeast beta glucan supplementation increases salivary IgA and decreases cold/flu symptomatic days after intense exercise.
Well-supported findings on immunity
We aimed to explore the effects of baker's yeast β-glucan (BG) on the immune system of those engaging in intense exercise. In two experiments involving over 240 men and women, we found that BG reduced cold and flu symptom days by 37% after a marathon compared to a placebo. Additionally, BG boosted salivary IgA levels, which is crucial for immune defense, by 32% after strenuous cycling. This suggests that BG could be beneficial for those at risk of upper respiratory infections following intense physical activity.

Yeast beta-glucan reduces cold episodes
Yeast (1,3)-(1,6)-beta-glucan helps to maintain the body's defence against pathogens: a double-blind, randomized, placebo-controlled, multicentric study in healthy subjects.
Demonstrated potential health benefits
We conducted a clinical trial to see if brewers' yeast, specifically its beta-glucan component, could reduce common cold episodes in healthy individuals.

In this study, 162 volunteers took either yeast beta-glucan or a placebo for 16 weeks. Each participant tracked their cold episodes and symptoms.

We found that those taking the yeast supplement had 25% fewer colds and reported better overall symptom management compared to the placebo group. Notably, participants experienced fewer sleep disturbances related to their colds.

Supports microflora
Indispensable for the digestive tract, bouladri saccharomycetes are one of the probiotics beneficial for colds. They alleviate swelling and support healthy microflora by eliminating pathogenic bacteria. Saccharomycetes should be in everyone’s first aid kit as they are beneficial for common colds, poisoning, and maintaining gastrointestinal health. Wishing everyone good health and smiles!

Favourable replacement
I drink this for colds once a day. Colds used to always lead to bronchitis, but now the illness lasts less than a week and without complications. This is thanks not only to saccharomycetes but also to my overall health, including levels of vitamin D and zinc. I replaced Enterol prescribed for Helicobacter with these saccharomycetes instead, as I found the dosage higher and the price more favourable.
