Yeast supplement reduces cold symptoms
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.

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.

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.

Reduced intestinal discomfort
179 people found this helpful
I initially used this for an anti-candida protocol, but had to administer it early. My child suffered from terrible intestinal discomfort. However, after introducing Saccharomyces on the tenth day, the rumbling stopped, and he seemed calmer. The capsules are large and difficult for a child to swallow, but I diluted them in cold water and used a syringe. Thankfully, everything seems to be fine.

This is an excellent supplement! Saccharomyces can be taken alongside antibiotics, which is essential these days. They help maintain intestinal microflora during treatments. They don’t permanently settle but assist in keeping good bacteria. I've found them helpful for managing common colds and digestive issues.

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
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.

I take this occasionally for its price, quality, and effectiveness! It's handy during colds, for detoxing, or following a course from candida. I use it for a mini-course of 3-5 days and find that overuse diminishes its effect.
