EpiCor to Boost the Immune System?

Question:
What is EpiCor? Does it really "boost" the immune system and prevent colds?

Answer:
EpiCor® is a branded ingredient produced from the fermentation of "whole food" by brewer's yeast (Saccharomyces cerevisiae). According to the manufacturer (Embria Health Sciences), it contains number of compounds including beta glucan, a type of soluble fiber. Preliminary studies funded by Embria suggest EpiCor may increase some measures of immune system function and, if taken daily, slightly reduce certain symptoms of allergy and the incidence of colds or flu. Larger, independent studies are needed to confirm these findings. For details, including information about the safety of Epicor, see the full answer >>

See the Encyclopedia articles about Brewer's Yeast and Beta Glucan for more information about these supplement ingredients.

I am concerned that Epicor could trigger off a cytokine storm like other immune-boosting supplements such as Elderberry. Do you have any information about that?

As noted above, there is some evidence that Epicor may cause an increase in saliva Immunoglobulin A (IgA). IgA may induce cytokine production and inflammation (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6513800/), although we are not aware of any published reports of Epicor causing or being suspected of causing cytokine storms in people. For more information about the concern about elderberry and cytokines, please see the COVID-19 section of the Elderberry Supplements Review: https://www.consumerlab.com/reviews/elderberry-supplements-reviewed/elderberry/#covid.

I have not had a cold for a couple of year since I've taken Epicor and if I feel a bit of a sore throat I take Oscillo. if I am going into a place with crowds or on an airplane I also take Oscillo .
And all that is the same for my husband as well and we are both over 80

Thank you for sharing this Karen. You can find more information about Oscillococcinum in the Encyclopedia article about homeopathic remedies for flu https://www.consumerlab.com/tnp.asp?chunkiid=38325.

My mother and I have been taking Epicor (500mg) for 4 years. We have not expereinced any cold or flu during ths time period. We both will happily continue to take Epicor on a daily basis.

This is from personal experience - and I have no financial interest in Epi-Cor.

I was diagnosed with CLL leukemia in 2009 (untreated currently classified as untreated watch & wait). CLL primarily compromises the immune system so that there is a greater risk of infection. To help my immune function I have been taking several supplements. Epi-Cor along with vitamin D3, etc.
After adding Epi-Cor to my daily routine I experienced a reduction to the number of minor infections that I was experiencing - this has continued for the past 14-16 months.
