MegaMucosa Background 

MegaMucosa TM is the first complete mucosal support supplement of its kind, formulated to REBUILD a healthy mucosal barrier and restore gut health. MegaMucosa TM also contains dairy-free immunoglobulins clinically shown to support a healthy immune response in the mucosa and a state-of-the-art flavobiotic clinically shown to support microbial diversity and alleviate barrier dysfunction, otherwise known as leaky gut. 

The mucosal system is a very important part of the human immune system. Not many people think of mucus as being protective, but it is the main interface between the human body and the outside world. The mucosal system contains 150 times more surface area than skin, which makes it one of the most important immune barriers. The health of the mucosa determines how the body interacts with antigens; therefore, the integrity of the intestinal mucosa can dictate overall immune function.1

Research suggests that the intestinal mucosal barrier plays a significant role in the pathogenesis of many chronic conditions, including inflammatory bowel diseases (IBD), depression, acquired immunodeficiency syndrome (AIDS), gastroesophageal reflux disease (GERD), acute pancreatitis, and more.2-6 Some researchers even believe that mucosal damage may be the initial injury that leads to many of these chronic conditions. Unfortunately, the Western lifestyle is quite damaging to the intestinal mucosa. Antibiotics, NSAIDs, stress, alcohol, gut infections, and other factors can easily degrade the intestinal mucosa, weakening the immune system and allowing unwanted toxins to enter circulation and trigger an inflammatory response.

MegaMucosa Ingredients

MegaMucosa TM contains four amino acids, MicrobiomeX ® bioflavonoids from citrus sinensis and citrus paradisi, and ImmunoLin® serum-derived bovine immunoglobulins.

MegaMucosa TM is formulated to help the body rebuild its protective intestinal barriers. The mucosal layer that protects the intestinal mucosal lining consists of a thick, gel-like protein known as mucin2. In order to increase the synthesis of this protein, the body needs a plentiful supply of butyrate and four amino acids: L-proline, L-serine, L-cysteine, and L-threonine.

MicrobiomeX ® is a natural citrus extract rich in polyphenols that supports digestive health and immunity by increasing microbial diversity in the gut and improving gut barrier function. A clinical study using 500mg of citrus fruit extract found a 22% increase in butyrate production and a significant reduction in fecal calprotectin. Both results suggest that citrus polyphenols can reduce inflammation and modulate the microbial composition in the gut. 

Finally, the addition of the dairy-free immunoglobulins provides immune protection from the numerous toxins in the GI tract. Serum-derived immunoglobulins will enter the digestive tract and begin binding and neutralizing toxins in the gut before leaving the system through defecation. In this way, the immunoglobulins help to reduce the toxic load in the gut and buy time for the intestinal lining and mucosal barrier to repair themselves with the necessary building blocks. These IgG antibodies can reduce the damage of metabolic endotoxemia and neutralize LPS, an endotoxin that triggers mucosal inflammation. 

Together, these ingredients function to reduce the overall toxic load on the gut and rebuild a strong and healthy mucosal barrier.

MegaMucosa TM was formulated to REBUILD intestinal barriers. Rather than just follow the crowd with this formula, Microbiome Labs chose to innovate a comprehensive product based on research that could effectively rebuild the intestinal mucosa. Addressing the intestinal mucosa is key because a thick mucosal barrier is what ultimately protects the intestinal lining from toxins and pathogens. Rather than just focusing on rebuilding the intestinal mucosal lining, Microbiome Labs is focused on rebuilding from the ground up in order to provide a more reliable foundation. 

Many gut health supplements are designed to soothe intestinal inflammation, but they often do very little to address the root cause of the inflammation. MegaMucosa TM, on the other hand, helps to quickly reduce the toxic load on the body while also rebuilding protective barriers. In this manner, MegaMucosa TM is more multi-functional and robust than other common gut healing supplements. Additionally, MegaMucosa TM uses serum-derived bovine immunoglobulins (SBI) rather than colostrum-derived immunoglobulins. See our previous post on Mega IgG2000 to learn more about the benefit of SBI.

Suggested Use

Take 1 scoop daily with or without food, or as directed by your healthcare practitioner. Mix into 16 oz of cold water or liquid of your choice. 

MegaMucosa TM is safe for children and safe to use while pregnant and nursing. 


MegaMucosa TM works best when taken together with MegaSporeBiotic TM and MegaPreBiotic TM, as part of the Total Gut Restoration system. 


MegaMucosa TM can be taken indefinitely at the suggested dose of 1 scoop daily or at a maintenance dose of 1 scoop weekly. 


You should not take this product if you are vegan. Use with caution if you have an allergy to beef, as the immunoglobulins are derived from the serum of cows.
