General product information
What is EnteraGam®?
What is medical food?
How can EnteraGam® help?
EnteraGam® uniquely addresses the underlying factors that may contribute to chronic diarrhea and loose stools in people with specific intestinal disorders, like IBS-D or IBD. Print this free Doctor Discussion Guide to help you talk to your doctor about EnteraGam®.
In a clinical study, people who took EnteraGam® experienced fewer days per week with loose stools and other IBS-D–related symptoms, including abdominal discomfort and bloating. Some people notice management of their condition with EnteraGam® in as little as 2 to 4 weeks.9 See how EnteraGam® works.
How many packets are in a box?
Each box of EnteraGam® has 30 packets in it.
What is the bacteria count in millions in a packet of EnteraGam®?
Is EnteraGam® safe?
Why must EnteraGam® be taken under physician supervision? Can it be dangerous?
EnteraGam® is classified as a medical food, which is the gold standard for safety and must be administered under physician supervision because it is used for chronic diseases such as IBS-D and IBD.
How it works
How does EnteraGam® work?
EnteraGam® uniquely binds toxic substances released by bacteria (and other substances called microbial components1) that upset the intestinal environment. This helps prevent them from penetrating the lining of the intestine and causing problems.
EnteraGam® may also help:1-8
- Restore a stable environment in your gut (called gut homeostasis)
- Manage how your gut barrier works (called gut barrier function) so nutrients from foods and fluids can be properly absorbed
If Cholestyramine has helped in the past, do you think EnteraGam® will help now?
EnteraGam® works differently by targeting the root cause of chronic loose stools in the gut by binding and removing pathogenic bacteria before they can cause an inflammatory response.
Does EnteraGam® help with gas?
In a randomized placebo-controlled trial, EnteraGam® was shown to reduce the number of days with IBS-D symptoms such as flatulence by 35%.
Can EnteraGam® be used for diarrhea that comes from c difficile?
The concentrated antibodies in EnteraGam® specifically bind to c. difficile, making it a great treatment option for diarrhea associated with c. difficile infection.
Is EnteraGam® still helpful to patients even if they don’t have diarrhea/loose stools?
Absolutely, EnteraGam® helps maintain gut barrier function, which has many positive effects. In a randomized placebo-controlled trial, EnteraGam® significantly decreased the number of days patients experience abdominal discomfort, urgency, bloating, and flatulence.
Can EnteraGam® be used for constipation?
IBS-C is currently not part of the labeled intended use for EnteraGam®. Therefore, use in this patient population is up to the patient’s physician. We do not have any formal clinical data in IBS-C patients, though we reported some IBS-C patient responses in case studies. Since EnteraGam® is intended for patients with chronic loose and frequent stools, and it does cause mild constipation in clinical studies (2-5%), it may not be appropriate for IBS-C patients.
Can EnteraGam® be used for IBS with constipation?
IBS-C is currently not part of the labeled intended use for EnteraGam®. Therefore, use in this patient population is up to the patient’s physician. We do not have any formal clinical data in IBS-C patients though we reported some IBS-C patient responses in case studies. Since EnteraGam® is intended for patients with chronic loose and frequent stools, and it does cause mild constipation in clinical studies (2-5%), it may not be appropriate for IBS-C patients.
Does EnteraGam® help with leaky gut?
EnteraGam® is indicated for the dietary management of chronic loose and frequent stools related to IBS-D. It has been shown to help manage gut barrier function which may lead to improvements with leaky gut symptoms such as loose stools, flatulence, and bloating.
Does EnteraGam® help with a bowel obstruction?
EnteraGam® has not been extensively studied in patients with bowel obstruction. Please consult your doctor.
Will EnteraGam® work for a person with microscopic colitis?
EnteraGam® is a great addition to the standard of care for patients with IBD, such as microscopic colitis, Crohn’s disease, and ulcerative colitis.
Will EnteraGam® work for a person with hydrogen dominant SIBO?
Small intestinal bacterial overgrowth (or SIBO) can be caused by many things including: lack of proper stomach acid production that can normally kill bacteria in the small intestine; infection by bacteria; and as part of other diseases and conditions (i.e., Crohn’s disease, IBS). SIBO patients experience IBS-like symptoms. We have performed one retrospective analysis on the effect of EnteraGam® (1 packet BID) on patients diagnosed with SIBO by lactulose breath test who were refractory to treatment with the antibiotic Xifaxan®. The study showed that EnteraGam® managed SIBO in 70% of these patients.
Will EnteraGam® help with H2S bacteria overgrowth?
EnteraGam® binds and removes a variety of antigens, but it has not been extensively studied in patients with hydrogen dominant SIBO. Please consult your doctor.
Will EnteraGam® work for a person with Crohn’s disease? Has it been studied in connection with Crohn’s?
EnteraGam® is a great addition to the standard of care for patients with IBD, such as microscopic colitis, Crohn’s disease, and ulcerative colitis.
Will EnteraGam® work for a person with terrible fibromyalgia pain post osteomyelitis and its treatment?
EnteraGam® has not been extensively studied in this patient population. Please consult your doctor.
Will taking EnteraGam® help with my lactose intolerance?
EnteraGam® is derived from bovine serum and is dairy and lactose-free, making it a great treatment option for patients who present with IBS-D or chronic loose and frequent stools who also have a problem digesting lactose. However, it will not act directly on the lactose tolerance of the patient or improve it in any way.
Probiotics and antibiotics
How is EnteraGam® different from probiotics?
EnteraGam® is not a probiotic. Probiotics simply add bacteria to the intestinal environment. They may be harmful for people who have a weakened immune system and are at risk of getting infections because their bodies cannot defend against illnesses or other medical problems.11
Plus, probiotics do not work like EnteraGam® to prevent the toxic substances released by bacteria and other microbial components from penetrating the lining of the intestine, which may contribute to chronic diarrhea and loose stools due to specific intestinal disorders, like IBS-D or IBD.3,12 See About EnteraGam® to learn more.
How is EnteraGam® different from antibiotics?
EnteraGam® is not an antibiotic. Antibiotics can contribute to diarrhea by damaging the microbiome which leads to gut barrier disruption or leaky gut. Antibiotics are also not safe for long-term use for IBS-D, which is often a chronic condition.10 You can take EnteraGam® as long as you want, and you do not need any special blood tests or other monitoring tests. And with EnteraGam®, you do not have to worry about bacterial resistance like you do with antibiotics.8,10 See About EnteraGam® to learn more.
Use with other health products
Can I use EnteraGam® with other therapies?
EnteraGam® can be safely taken along with other therapies for chronic diarrhea and loose stools that your doctor has prescribed. EnteraGam® can also be safely taken with any other medications or therapies for other conditions.8 Learn more about the safety of EnteraGam®.

Do you have any information on results or testimonials or reviews about people that take EnteraGam® with Humira®?
EnteraGam® is a great addition to the standard of care for patients with Crohn’s disease or ulcerative colitis who may be taking Humira®.
Can EnteraGam® be taken with Xifaxan®?
EnteraGam® has no drug-to-drug interactions and acts locally in the GI tract, making it a great addition to Xifaxan®.
Can I continue to take MiraLAX® while taking EnteraGam®?
EnteraGam is indicated for the management of chronic loose stools related to IBS-D. MiraLAX® is commonly used to manage constipation, and therefore you should consult your doctor about using both products together.
Can I continue taking Lactaid® while I take EnteraGam®?
EnteraGam® has no drug-to-drug or supplement interactions and therefore will have no effect on Lactaid.
Can EnteraGam® be taken with other commonly prescribed medications for IBS-D, such as Imodium®, probiotics, and dicyclomine?
EnteraGam® has no drug-to-drug or supplement interactions and therefore is a great addition to your current medication regimen to help manage chronic loose and frequent stools.
