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.

Effective cold treatment
10 people found this helpful
I'm very satisfied with this product! I noticed a clear difference in my symptoms when I took it. During a cold with a sore throat or runny nose, I took 4 tablets daily: 2 in the morning and 2 in the evening on an empty stomach, ideally combined with lactic acid bacteria. I regret any days I forgot to take them. The tablets are easy to swallow, odourless, and well-priced. I'll definitely buy more after I finish my current bottles. I highly recommend this to everyone!

My mother's keeper :) My mum is asthmatic and has always been susceptible to various winter health issues and pollen allergies. I purchased the NOW foods beta glucans (100mg) for her 2.5 years ago, and she has taken one capsule daily since. I can't recall the last time she had a cold or flu. I've now opted for the 250mg dosage for extra safety due to the current situation. She remains perfectly healthy despite going out. Remarkably, her blood sugar and cholesterol levels have normalised after years of being elevated, which is said to be an effect of beta glucans. It's a double win for us!

Baker's yeast supports immune function
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.

This Recovery Accelerator is essential for me! Whenever I notice cold symptoms, I start taking Beta-Glucans, which have often prevented me from becoming seriously ill. Even when I do fall ill, taking this product helps me recover quickly and easily. Previously, I frequently caught colds, but this product has significantly improved my quality of life and bolstered my immunity.

Reduced frequency of colds

This is a product I have repurchased many times! My immunity isn’t great. Whenever the weather changes or my child catches a cold, I panic. However, since using this product, my colds have decreased and when I do catch one, recovery is quicker. Previously it took 7-8 days; now, it's only 3 days!

Convenient usage
3 people found this helpful
I've previously bought powdered dextran from other brands, but found it cumbersome. This vegetarian capsule is much easier to carry. I take two capsules when I feel the onset of a cold, and after three days, my symptoms reduce significantly. It supports my immunity without needing medication.

Great product! I took this Beta Glucans supplement with Immune Renew. For the first time in years, I didn't catch colds during winter, likely due to these immune-boosting supplements.

Effective immuno-booster

I sought to boost my immune system after being diagnosed with HPV and found beta-glucans quite effective. After a year of consistent use, I haven't experienced many colds and have seen improvement in my HPV conditions. I combine these with Zinc and AHCC for the best results, and overall, I consider them a great investment.

Great supplement for immunity at the first sign of a cold! It helps speed up recovery and heals mucous membranes. We take two capsules three times a day during illness and until full recovery. My husband takes two once daily to reduce his appetite.
