Product details "FLORASSIST® Immune & Nasal Defense"
Health benefits at a glance:

Seasonal changes can increase the number of microscopic stimuli like the amount of pollen, dust, or pet dander in the air. This can, in turn, cause your immune system to overreact which can result in discomforts in the eyes, airways, and skin.

Our immune system is our body’s built-in line of defense. Coincidentally, it also reacts to harmless things in your environment such as those mentioned above.

This supplement contains EpiCor®, a yeast fermentate of S. cerevisiae, and L. rhamnosus CRL1505, a probiotic strain, that can encourage multiple aspects of a healthy immune response, so you can also stay comfortable when seasonal changes occur.

EpiCor® was discovered when factory workers at a yeast fermentation plant had better work attendance than their office counterparts.

Moreover, FLORASSIST® Immune & Nasal Defense is gluten-free, non-GMO, and vegetarian.

Why it works:

Our immune system operates with the best interests of our body at heart. However, sometimes "things" in environmental factors like pollen and other seasonal challenges, test out immune system. 

We want our immune system to produce immunoglobulin A (IgA) in order to help protect us. At the same time, our immune system should ignore harmless things in our environment, otherwise it may produce an excess of histamine — a compound that affects airflow in nasal passages. 

So to prepare for any immune system challenge, we need to promote a healthy immune response to the world around us. 

That’s where FLORASSIST® Immune & Nasal Defense comes in.

The science behind the product: 

FLORASSIST® Immune & Nasal Defense contains a unique combination of ingredients that can help balance your immune system during seasonal changes:

From Brewer's yeast: EpiCor® of S. cerevisiae

Scientific discoveries can happen when you least expect it. For instance, factory workers at a yeast fermentation plant took fewer sick days compared to their colleagues in office settings. 

Research revealed that those on the factory floor had heigher levels of secretory IgA and natural killer cell activity than those working than those working in a cubicle. Secretory IgA and natural killer cells both play vital roles in maintaining a robust, healthy immune system.

EpiCor® is a fermentate of from S. cerevisiae, a microorganism more commonly recognized as brewer's yeast. Its discovery was purely coincidental as mentioned above, and since then EpiCor® has been the subject of a half-dozen clinical studies.

EpiCor® serves to enhance the body's natural immune response. Curiously, EpiCor® also lends a hand to the immune system in dealing with innocuous environmental factors like pollen. In one study, subjects took either 500 mg of EpiCor® a day or a placebo for five weeks.

Subjects in the EpiCor® group who normally experienced an immune response to changes in their environment reported none of those same effects while taking EpiCor®. (1) 

In two additional studies, individuals taking EpiCor® reported reduced duration and intensity of immune reactions compared to those receiving a placebo. (2,3) 

EpiCor® appears to work by promoting natural killer cell activity as well as the production of secretory IgA, two little-known but absolutely essential parts of your body’s immune defenses

In one study, subjects taking 500 mg of EpiCor® a day for 8 weeks saw an increase in secretory IgA. (1) In another study, EpiCor® increased markers of natural killer cell activity, after just a single 500 mg dose. (4)

The probiotic strain Lactobacillus rhamnosus CRL-1505

Lactobacillus rhamnosus CRL1505 stands out as a unique probiotic strain originally isolated from goat's milk and discovered in the northwestern region of Argentina. 

This particular strain, L. rhamnosus CRL1505, plays a significant role in promoting a robust immune response, to the extent that it is administered annually to more than 300,000 school children in Argentina for this very purpose. (5,6)

In a randomized, double-blind, placebo-controlled trial involving hundreds of Argentinian school children, subjects receiving L. rhamnosus 5 days a week for 6 months had nearly 50% less recorded instances of immune challenge compared to those taking a placebo.

This same study found that the L. rhamnosus group also had 47% higher levels of secretory IgA, which supports a healthy immune response. (5)
