Flora-Fortifying EpiCor® Postbiotic

You know probiotics, but you might not have heard about postbiotics. Postbiotics are the gut-friendly product of whole-food fermentation that provide support for digestive and immune health. Backed by 75 years of proprietary fermentation experience and 8 gold-standard clinical trials, EpiCor delivers a year-round boost to immune health through its robust blend of gut-nourishing metabolites made up of vitamins, minerals, amino acids and so much more.1*

Immune-Strengthening Over Immune-Boosting

You may have seen the term “immune booster” on supplement shelves, offering temporary support from seasonal issues. IMMUNE is formulated with EpiCor, an immune-strengthening postbiotic offering comprehensive support for gut and immune health. While an immune booster is something you may only take for a short period of time as a seasonal boost, an immune strengthener supports your immune system throughout the year and can be taken daily for beneficial results.*

Natural Immune-Boosting Vitamin C and Zinc

Vitamin C and Zinc have long been recommended by physicians to help patients boost their immune systems. Research supports the role of zinc in providing seasonal and systemic protection, reducing the number of days missed from school or work for those properly supplementing.3,4*

EpiCor® Postbiotic

EpiCor is a whole-food fermentate derived from yeast, a natural microorganism. Its immune-strengthening properties were discovered through observational happenstance, when factory workers at Diamond V—a plant fermenting grains for animal feed—were taking noticeably fewer days out than those working in the office. Upon looking into it, researchers found the fermented feed had delivered measurable immune support to the exposed factory workers.

Today, EpiCor is developed using a proprietary fermentation process backed by 75 years of expertise and 8 gold-standard clinical trials. Its production begins with baker’s yeast—the kind used for centuries to make products like bread and wine. Once fermented, the result is a minimally processed postbiotic rich in metabolites, antioxidants, fibers, proteins and other beneficial compounds that support healthy gut and immune function. When taken regularly, the microbiome-boosting benefits of EpiCor provide year-round support to your immune system.1*

Leading with safety and science, EpiCor is produced in an NSF-certified facility in Ankeny, Iowa. The formulation has undergone eight human clinical trials and a series of peer-reviewed safety studies published in the International Journal of Toxicology. EpiCor fermentate is also Non-GMO Project Verified, Kosher, gluten-free and vegan.

Vitamin C

Vitamin C is a powerful antioxidant, protecting the body against oxidative stress. Equipped with 100% of the recommended daily intake of high-potency Vitamin C, this formula supports year-round immunity.3


Zinc is an essential mineral playing a role in healthy immune function. Studies have demonstrated its capacity to provide relief from seasonal issues when supplemented early in the onset of issues.4*

Take 1 capsule daily as a dietary supplement for year-round immune support.

Didn’t receive all my products

I ordered two Ashwaganda bottles (order one and get 1 half price) and one Immune Postbiotic and somehow only got one bottle of the ashwaganda in the package. I sent the company a message 2 weeks ago and have not heard back from them. Not going to give them a high score.

Good combination

Just started using. Like the idea of ingredients in capsule form with no extra fillers. Zinc and vitamin C is a good combination. Would have given it 4 stars if the vitamin C was more natural instead of ascorbic acid.
