Summary of Human Clinical Trials

EpiCor fermentate has undergone eight human clinical trials, all of which have been published in peer-reviewed scientific journals and have used a standard dose of 500 mg per day. Six of the eight trials conform to the “gold standard” of clinical design in that they were randomized, double-blinded, placebo-controlled trials. Results show that EpiCor supports a strong, healthy immune system while it balances immune response; and significant measurable results can be seen in as little as two hours. The scientific evidence demonstrates:

  1. Supporting a Strong, Healthy Immune System by Significantly Increasing sIgA1: The first published trial was the only trial that used an in-house, open-label model on 22 healthy subjects. The trial studied whether EpiCor provided immune support by increasing sIgA, an antibody that is integral in the body’s first line of defense. Results showed that EpiCor supports immune strength by significantly (p<.05) increasing sIgA relative to baseline.

  2. Balancing and Strengthening Immune Response by Reducing IgE (relative to placebo) While Increasing sIgA1: The second published trial was a randomized, double-blinded, placebo-controlled trial on 25 healthy subjects ages 18-43. This five-week trial examined EpiCor’s effect on sIgA and IgE, which are antibodies associated with pathogen defense and allergies respectively. Results showed that EpiCor balanced and strengthened immune response by reducing IgE (relative to placebo) while increasing sIgA.

  3. Flu-Vaccinated Subjects Saw Significantly Reduced Incidence and Duration of Symptoms from URTIs2: The third trial, published in a MEDLINE-indexed journal, was a randomized, double-blinded, placebo-controlled, 90-day trial on 116 healthy subjects ages 18-76. The trial examined whether EpiCor had a beneficial effect on the incidence and duration of cold and flu symptoms for subjects who had received a flu vaccination. Results showed that EpiCor supports immune strength by significantly (p<.05) reducing the incidence and duration of cold and flu symptoms.

  4. Non-Vaccinated Subjects Saw Significantly Reduced Incidence of Symptoms from URTIs3: The fourth trial, published in a MEDLINE-indexed journal, was a randomized, double-blinded, placebo-controlled, 90-day trial on 116 healthy subjects ages 18-94. The trial examined whether EpiCor had a beneficial effect on the incidence of cold and flu symptoms on subjects that did not receive a flu vaccination. Results mirrored the third trial showing EpiCor supports immune strength by significantly (p<.05) reducing the incidence of cold and flu symptoms.

  5. Significantly Reduced Allergy Symptoms4: The fifth trial, published in a MEDLINE-indexed journal, was a randomized, double-blinded, placebo-controlled trial on 96 healthy subjects, ages 18-70, that had tested positive for allergies. The 90-day trial studied EpiCor’s ability to reduce allergy symptoms. Results showed that EpiCor significantly (p<.05) reduced the incidence of certain allergy symptoms – especially nasal congestion – while increasing sIgA levels, which are associated with immune defense.

  6. Rapid Response by Significantly Increasing Serum Antioxidant Protection and NK Cell Activity in Just Two Hours5: The sixth trial, published in a MEDLINE-indexed journal, was a randomized, double-blinded, placebo-controlled trial on 12 healthy subjects ages 18-55. This trial examined how quickly EpiCor had an effect on the body’s immune system. Results showed that EpiCor begins to support immune strength rapidly by significantly (p<.05) increasing antioxidant protection and NK cell activation.

  7. Reduced Inflammatory Response to Histamine-Induced Skin Inflammation, Suggesting Similar Effects May Happen Across Mucosal Membranes After Consumption6: The seventh trial, published in a MEDLINE-indexed journal, was a single blind, placebo-controlled, crossover study involving 12 healthy subjects ages 18-55. Clinical results demonstrated significantly reduced microvascular inflammatory responses to histamine-induced skin inflammation, and significantly (p<.05) reduced subjective scores of irritation at the inflamed sites treated with EpiCor fermentate compared with the sites treated with placebo. The effects using a topical skin model suggest that similar events may happen when the EpiCor is introduced across mucosal membranes after consumption.

  8. Improved Constipation Symptoms, Gastrointestinal Comfort and Beneficial Gut Microbiome Levels7: The eighth trial, published in a MEDLINE-indexed journal, was a randomized, double-blinded, placebo-controlled, on 80 subjects with symptoms of gastrointestinal discomfort and constipation were equally allocated to one of two trial arms: placebo or 500 mg EpiCor fermentate. Clinical results demonstrated significantly (p<.05) reduced overall digestive discomfort and improved stool consistency while significantly increasing genera Bacteroides and Prevotella.

Trial 1) Strengthening the Immune System by Significantly Increasing sIgA

A summary of a study published in the Open Nutrition Journal1

Introduction: sIgA is an antibody that is part of the human body’s first line of defense and is integral to a healthy immune system. This antibody is produced from the mucosal-associated lymphoid tissue, which accounts for over 70% of the total immune system. As the majority of human infections arrive via breathing, touching and eating, sIgA is an essential part of the body’s initial immune defense against pathogen exposure. Embria sponsored the first human clinical trial to establish whether EpiCor provides immune support by increasing beneficial salivary sIgA levels.

Method: Twenty-two healthy subjects who had never taken EpiCor before, were recruited for this in-house, open-label 90-day trial. During the first 30 days of the trial, baseline concentrations for each subject were established for sIgA by measuring saliva samples, which were collected twice a day, three times a week. For the remaining 60 days, the subjects were then given one 500 mg capsule of EpiCor per day while researchers continued monitoring sIgA levels.

Results: After 30 days, results showed a strong trend (p<0.09) for increased sIgA over baseline, and after 60 days the average sIgA levels among the subjects were statistically significantly higher (p<0.05) than the baseline levels (Fig. 1). These results indicate EpiCor increased sIgA in just a matter of a few weeks. It also suggests that it takes time for the body to obtain the full benefits from EpiCor, and that continuous use is preferred for the most beneficial effects.

Trial 2) Balancing and Strengthening Immune Response by Reducing IgE (relative to placebo) While Increasing sIgA

A summary of a study published in the Open Nutrition Journal1

Introduction: Immune strength requires the immune system to respond appropriately to stressors that affect overall health. In human clinical trial one, EpiCor supported immune strength by increasing sIgA. Further studies were needed to show EpiCor’s immune balancing abilities by simultaneously increasing sIgA and reducing unfavorable immune responses such as those represented by allergy symptoms. IgE is an antibody associated with the allergic reactions to harmless substances such as pollen and dust. IgE primes allergic response by binding to Fc receptors found on the surface of mast cells and basophils. The second human clinical trial investigated the effects of EpiCor on the immune markers, sIgA and IgE, as well as the incidence of allergy symptoms.

Method: The trial used a double-blinded, placebo-controlled model on 25 healthy subjects, ages 18-43, and was conducted in the spring when allergies become an issue for some people. Subjects were given either EpiCor (500 mg) or placebo for five weeks.

Results: At the end of the trial, subjects showed decreased IgE in the EpiCor group relative to placebo which suggests the important immune balancing effects of EpiCor. Specifically, IgE was expected to show an increase during the time frame of the trial because of its association with the onset of allergies. In the placebo group, results showed the expected increase in IgE while also showing a decrease in sIgA. However, the EpiCor group showed increased sIgA levels while IgE levels remained nearly at baseline (Fig. 2). Laboratory results confirmed standardized questionnaire findings where subjects reported fewer allergy problems than usual. The questionnaire also showed that the EpiCor group reported significantly fewer health complaints compared to the placebo group.

Figure 2. The Effect of EpiCor on Salivary sIgA and IgE

It was also observed in this trial that cytokine profiles were modulated in the EpiCor group – again demonstrating the immune balancing properties of EpiCor. This result is consistent with EpiCor research using animal models that also demonstrated the multiple effects of EpiCor and its ability to support immune strength by helping to balance immune response and prevent over-reaction such as inflammation.

Although the results did not reach full statistical significance due to both the small number of subjects and the shortness of the trial, it showed a strong trends and led to larger more definitive human clinical trials.

Trial 3) Flu-Vaccinated Subjects Saw Significantly Reduced Incidence and Duration of Symptoms from URTI

A summary of a study published in Urological Nursing2

Introduction: URTIs are reported to be the most commonly contracted illness. Maintaining a balanced, healthy immune system is expected to reduce the average number of days with URTI symptoms. The third human clinical examined whether EpiCor reduced the incidence and duration of cold and flu symptoms.

Method: To determine the effect of EpiCor on strengthening the immune system, a 90-day trial was conducted in South Dakota during the worst expected cold and flu months – Jan. though Mar. The trial was a double-blinded, placebo-controlled trial on a group of 116 adults, ages 18-76, who had been vaccinated against the flu. This large group was chosen to represent the general vaccinated population.

At the beginning of the trial, subjects received physical examinations at screening to ensure a healthy study population and were randomly assigned to receive either EpiCor (500 mg) or placebo. Fasting blood samples were taken at randomization and at weeks six and twelve (when the trial ended). In addition, each subject was instructed to record the incidence, duration and severity of cold and flu symptoms.

Results: The EpiCor group had statistically significantly reduced (p<0.05) incidence of URTI symptoms compared to the placebo group. Additionally, when the EpiCor group had URTIs, the duration of symptoms was significantly shorter. The average number of days with symptoms was significantly reduced by 26% (Fig. 3).

Figure 3. The Effect of EpiCor on the Number of Days with Symptoms Experienced by Vaccinated Subjects

Trial 4) Non-Vaccinated Subjects Saw Significantly Reduced Incidence of Symptoms from URTIs

Published in the Journal of Alternative Complementary Medicine3

The fourth trial was a double-blind placebo-controlled trial on 116 healthy subjects who were not vaccinated against the flu. This trial was during the same time frame and place as the third trial – in South Dakota during the cold and flu season. Also, the same methodology and protocols were used. Because of this, results were expected to be very similar to and confirmed the findings in the third trial. There was a significant reduction in the incidence of symptoms and a strong trend toward reduced duration of symptoms. As in the third trial, the average number of days with symptoms was reduced by 26%. These results along with the third trial results show that flu vaccination does not affect the efficacy of EpiCor.

Trial 5) Significantly Reduced Allergy Symptoms

A summary of a study published in Advances in Therapy4

Introduction: Previously, in human clinical trial number two, EpiCor was shown to support immune strength and balance immune response by simultaneously helping increase sIgA while reducing IgE as compared to placebo. Animal studies also suggested EpiCor’s ability to balance immune response by significantly reducing inflammation. These results from previous studies led to the fifth trial. This trial examined EpiCor’s ability to balance immune response by helping reduce the incidence of certain symptoms from environmental allergens.

Method: In this double-blinded, placebo-controlled trial, subjects had to test positive for a susceptibility to allergies. Ninety-six healthy subjects, ages 18-70, tested positive and were randomized to take EpiCor (500 mg) or a placebo. The 90-day trial took place in South Dakota during the 2008 spring allergy season.

Results: The highest total pollen counts occurred during the first six weeks of the clinical trial. During this high pollen count period, the EpiCor group showed statistically significant reductions in several symptoms commonly associated with seasonal allergies. The EpiCor group had the greatest reductions in symptom incidence and severity when total pollen counts were highest, as would be expected. The largest symptomatic impact occurred with nasal congestion showing a 43% reduction in days with symptoms compared to placebo (Fig. 4). The most significant symptom reductions were:

Reduction in nasal symptoms

  • Reduction mean severity (p=0.03)

  • Runny nose (p=0.005)

  • Nasal congestion (p=0.04)

Trend toward reduction in itchiness and sneezing

Subjects were also asked to record when they used rescue medication for severe allergies.  The EpiCor group used statistically significantly less rescue medication for allergies compared to the placebo group. Biochemical data mirrored the effectiveness observed in the allergy diary and questionnaire comparing EpiCor to Placebo: 

  • The number of selective allergy producing lymphocytes was reduced in the nasal smears (p<0.05)
  • Downward trend of mean eosinophil percentage in nasal smears (p=0.056)
  • Downward trend of mean serum basophil percentage (p=0.082).
     

During the trial sIgA levels were measured for both groups. Subjects taking EpiCor had significantly increased levels of sIgA compared to placebo, which may play a role at mucosal protection. This study confirms previous studies suggesting that EpiCor helps strengthen and balance immune response without depressing the immune system.

Trial 6) Rapid Response by Significantly Increasing Serum Antioxidant Protection and Natural Killer (NK) Cell Activity in Just Two Hours

A summary of a study published in the Journal of Medical Food5

Introduction: Previous human clinical trials tested the ability of EpiCor to support immune strength and balance immune response. The sixth human clinical trial studied how quickly EpiCor can benefit the immune system.

Method: In this double-blinded, placebo-controlled crossover study, subjects fasted for 12 hours before arriving at the clinic for the trial. Questionnaires assessed previous meals, snacks, exercise, stressors, and recent sickness. After blood for baseline analysis was drawn, subjects consumed 500 mg of EpiCor fermentate or 500 mg of placebo. Further blood samples were taken after one and two hours.

Results: After treatment, the antioxidant protection capacity started rising very rapidly in the EpiCor group. After two hours the EpiCor group had statistically significantly higher serum antioxidant protection capacity than the placebo group (Fig. 5).

Figure 5. The Effect of EpiCor on serum antioxidant protection capacity

Furthermore, this human clinical showed that NK cells were activated in the same time frame. Within two hours of ingesting 500 mg of EpiCor, both the CD25 and CD69 activation markers of serum NK cells were significantly increased (Fig. 6).

Figure 6. The Effect of EpiCor on NK Cell Activation

These rapid responses complement the slower, modulatory effects of EpiCor, such as the increase in salivary sIgA and the ability to reduce the incidence of certain symptoms caused by environmental allergens.

Human Clinical Trial 7: Reduced Inflammatory Response to Histamine-Induced Skin Inflammation, Suggesting Similar Effects May Happen Across Digestive Mucosal Membranes After Consumption

A summary of a study published in the Journal of Medical Food6

Introduction: Inflammation is an important and necessary component of the innate immune system. The aim of this study was to expand the understanding of the anti-inflammatory properties of EpiCor by documenting specific effects on controlled inflammatory insults in vitro and in vivo.

Method: A human clinical study was conducted using a single blind, placebo-controlled, crossover study involving 12 healthy volunteers. The purpose of this procedure was to evaluate the resolution of a histamine-induced inflammatory response when the EpiCor solution was applied topically after the histamine response had been initiated.

The test procedure was performed in a manner similar to allergy skin testing with the exception of using the high sensitivity of the laser Doppler method to assess the microvascular blood perfusion, which allowed the use of much lower doses of histamine to provoke a measurable response.

On each healthy subject, a skin site was identified on the left and right inner forearms with EpiCor tested on one side and placebo on the other. A baseline reading of the microvascular blood perfusion was performed and inflammation was induced on each skin site by applying a dilute solution of histamine and performing a scratch using a sterile lancet. After the histamine solution was removed EpiCor or placebo was applied to the site. After One (1) min, the EpiCor or placebo was removed and the laser Doppler probes were gently reapplied to the sites. After 10 minutes the probes were removed, and each subject was asked to score the level of itching on each skin site using a 100 mm Visual Analogue Scale. The laser Doppler data were analyzed for the following parameters: the time to maximum blood perfusion (Tmax), and the slope of the curve generated during the resolution phase over time.

Results: EpiCor accelerated resolution of the inflammatory insult. Among the 12 subjects, the observed average Tmax on the site treated with EpiCor was significantly shorter than the Tmax seen for the site treated with saline  (p<.05) (Figure 6). In addition, the slope of the curve after Tmax, during the resolution phase, was also significantly reduced in the EpiCor group compared with the saline-treated site  (p<.05) (Fig. 7). This indicates that the increased blood perfusion caused by the histamine challenge resolved slower in the sites treated with saline, and that treatment of the inflamed site with the EpiCor resulted in faster inflammation resolution.

The data from the skin model presented here may have broader relevance, for example, the effects may correlate with the effects of EpiCor consumption on the gut epithelium.

Human Clinical Trial 8:  Improved Constipation Symptoms, Gastrointestinal Comfort and Beneficial Gut Microbiome Levels

A summary of a study published in BMC Complementary and Alternative Medicine7

Introduction: The aim of the study was to investigate the gut health effects of EpiCor fermentate in a healthy population with symptoms of gastrointestinal (GI) discomfort and reduced bowel movements. This study helped to confirm previous published in vitro and animal studies demonstrating EpiCor’s gastrointestinal and prebiotic benefits at only 500 mg dose.

Method: Using a double-blinded, placebo-controlled parallel design, 80 healthy subjects with symptoms of GI discomfort and constipation were equally allocated to one of two trial arms: daily dose of placebo or daily dose of 500 mg EpiCor fermentate. There was a two-week run-in phase followed by a six-week intervention phase. Randomization was done in a stratified manner according to symptom severity, resulting in two subgroups of patients: severe (n=55) and moderate (n=25). Results are given for the total cohort as well as for the severe and moderate subgroups.

Primary Endpoints: GI discomfort and quality of life parameters were measured using three different instruments: a GI symptoms diary and two validated quality of life questionnaires, the Patient Assessment of Constipation Quality of Life (PAC-QOL) and Perceived Stress Scale (PSS) questionnaires.

Secondary Endpoints: Qualitative changes in the microbiome of the gut were assayed using fecal samples that were collected at baseline and at three and six weeks. The general microbiota structure and profiles found in the samples were determined by Illumina® sequencing, a technique involving the amplification of a hypervariable region (V5-V6 region of the 16S ribosomal RNA) of bacterial DNA and sequencing of the amplified region.

Primary Endpoint Results
Within the first two weeks, the EpiCor moderate subgroup showed rapid and statistically significant improvements for gastrointestinal health when compared to placebo. Analysis of the results within the EpiCor groups showed those benefits were typically maintained throughout the remainder of the study.

Fewer significant differences were found between groups in the four and six week averages due to a noticeable placebo effect, which seemed to increase over time especially in the severe subgroup. This pronounced placebo effect is common for gut-related trials with gastrointestinal disorders such as functional constipation. This may explain why the placebo effect was generally more pronounced in the severe group.

There were more statistically significant improvements within the EpiCor group than within the placebo group at weeks four and six, although there were fewer significant differences when compared to placebo. This includes statistically significant improvements for stool frequency, quality of life and perceived stress within the EpiCor moderate subgroup but not within the placebo moderate subgroup.

Gastrointestinal Parameters
Subjects kept a daily diary recording five gastrointestinal symptoms including bloating/distention, gas, GI rumbling, feeling of fullness and abdominal discomfort.

All symptoms were assessed on a five-point: scale 0 (absent) to 4 (very severe). Averages over a two-week interval were calculated for each symptom and for the combined scores of all the symptoms, giving daily total score (DTS).

Gastrointestinal Results:

  • Significant improvement in DTS in the EpiCor moderate subgroup compared to placebo moderate supgroup (Fig. 10).
  • Significant reduction in bloating/distension in the EpiCor moderate subgroup compared to placebo moderate subgroup (Fig. 8).
  • Significant reduction in feeling of fullness in the EpiCor moderate subgroup compared to placebo moderate subgroup (Fig. 9).

Figures 8 and 9.


Figure 10. EpiCor effects on daily total score for the moderate subgroup.

Figures 8, 9 and 10 show the mean differences between EpiCor and placebo for gastrointestinal symptoms (as recorded on a daily basis by self-assessment of the severity of GI symptoms on a five-point scale), analyzed with a linear mixed model that takes into account the differences between groups at baseline.

Stool Parameters
As a part of the patient diary, daily stool frequency and consistency were documented using the Bristol Stool Form Scale for a two-week run-in and a six-week intervention phase. Scores were averaged every two weeks.

The Bristol Stool Form Scale comprises seven types of stool: type 1 (separate hard lumps); type 2 (sausage shape lumpy); type 3 (sausage with cracks); type 4 (sausage but soft and smooth); type 5 (soft lobs); type 6 (fluffy and mushy); type 7 (liquid).

Types 1, 2 and 3 are associated with hard and impacted stools which can be linked with dysbacteriosis and chronic constipation. Types 4 and 5 are considered normal or optimal. Types 6 are considered subnormal or suboptimal. Type 7 is associated with diarrhea.

Bristol Stool Form Scale Results:

  • Significant improvements were seen in stool consistency in both the EpiCor total cohort group and the severe subgroup compared to placebo. The improvements were seen at week two, showing both a rapid and significant response to EpiCor. Also, it should be noted that within all EpiCor groups (total, moderate and severe) there were statistically significant improvements in stool consistency over time, while there were no significant improvements over time in any of the three placebo groups (Fig. 11).
  • Nearly significant improvement (p<0.10) for stool frequency was seen in weeks two and four in the EpiCor total cohort group as compared to placebo (Fig. 12). Also, highly significant improvements were seen within all three EpiCor groups (total, moderate and severe) over time.

Figure 11. EpiCor’s effects on stool consistency for the total cohort.

Figure 12. EpiCor’s effects on stool frequency for the total cohort.

Quality of Life Parameters
Quality of life was assessed through a validated Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaire at baseline and after three and six weeks of intervention.

PAC-QOL Results:

  • Significant improvement in Physical Discomfort within the EpiCor moderate subgroup but not within the placebo moderate subgroup.
  • Significant improvement in Psychosocial Discomfort within the EpiCor moderate subgroup but not within the placebo moderate subgroup.
  • Significant improvement in Satisfaction within the EpiCor moderate subgroup but not within the placebo moderate subgroup.

Perceived Stress Parameters
Perceived Stress was assessed through a validated Perceived Stress Scale (PSS) questionnaire at baseline and after three and six weeks of intervention.

PSS Results:

  • Significant decrease over time for both the EpiCor total cohort and severe subgroup, but not within the placebo group.
  • Nearly significant decrease in stress over time in the EpiCor total cohort and severe subgroup (p<0.10) when compared to corresponding placebo groups.

Secondary Microbiome Endpoint Results

Total Cohort:

  • Anaerostipes significantly increased within both the EpiCor total cohort and severe subgroup, but not within the corresponding placebo groups. Anaerostipes is a genus recognized for its health enhancing effects and contains acetate- and lactate-consuming bacteria and butyrate-producing bacteria.

Moderate Subgroup:

  • Akkermansia muciniphila significantly increased within the EpiCor subgroup but not within the placebo subgroup. Akkermansia muciniphila is important for proper gut function and is inversely correlated with metabolic disorders.
  • Blautia and Roseburia both significantly decreased in the EpiCor subgroup but not within the placebo subgroup. Blautia and Roseburia are believed to be higher in irritable bowel syndrome (IBS) and constipation-predominant IBS (C-IBS).

Severe Subgroup:

  • Statistically significant increase of Firmicutes, a less favorable bacteria phylum, within the placebo severe subgroup but not within the EpiCor severe subgroup (Fig. 13). Firmicutes to Bacteroidetes (F/B) ratio noticeably decreases in EpiCor total cohort (Fig. 13) and severe subgroup but increases in corresponding placebo groups. A two-fold increase in the ratio of Firmicutes to Bacteroidetes has been found in C-IBS patients when compared to healthy individuals.
  • Prevotella (Family Prevotellaceae) significantly increased in the EpiCor subgroup but not in the placebo subgroup. A lower incidence of Prevotella species has been associated with low-fiber diets and insufficient plant-based food consumption, which is a major cause of dysbiosis in constipated patients. The significant increase in Prevotella may partly explain EpiCor’s positive effects on stool frequency and consistency.
  • Bacteroides (Family Bacteroidaceae) significantly increased within the EpiCor subgroup while decreasing in the placebo subgroup. The significant increase in Bacteroides may also help explain EpiCor’s positive effects on stool frequency and consistency.

Figure 13. EpiCor’s effects on Firmicutes to Bacteroidetes (F/B) ratio.

The novel findings that EpiCor positively modulates the gut microbiota provide additional substantiation for its GI-related efficacy. EpiCor decreased the F/B ratio in the severe subgroup, which is known to be higher in C-IBS. Bacteroidetes, namely members of Prevotellaceae and Bacteroidaceae groups, are associated with acceleration of GI transit times. The significant increase within the severe subgroup of Bacteroides and Prevotella (both genera in the Prevotellaceae and Bacteroidaceae families) may explain EpiCor’s significant effects on stool consistency and nearly significant effects on stool frequency. Bacteroides and Prevotella have also been previously reported to be deficient in constipated patients. In the moderate subgroup, a significant increase in Akkermansia muciniphila was observed. Reduced levels of this bacterium have been correlated with metabolic disorders as well as with inflammatory conditions like IBS.  

These findings combined with past in vitro and animal studies show that EpiCor has substantial gut health benefits and can support a variety of claims regarding GI discomfort and microbiome modulation. (See our Structure Function Claims sheet for direction)

The compelling beneficial GI and microbiome results opens up vast opportunities to further research how EpiCor works through the gut to support both digestive and immune health.


Summary of EpiCor Efficacy Shown in EpiCor Clinical Trials

The results from these eight human clinical trials demonstrate the potential for EpiCor to play a beneficial role in helping healthy individuals maintain healthy immune and digestive systems. EpiCor has been shown to have positive effects on key parts of the immune and digestive systems that perform important functions to support overall health. Embria’s commitment to science ensures continued responsible research into EpiCor and its benefits.
