Leaky Gut: How to Fix It

Fix Leaky Gut Naturopathic Doctor Denver Colorado

First and foremost, start with my blogs on How to Prevent Leaky Gut, Leaky Gut Basics, and The 9 Causes of Leaky Gut.  You won’t be able to heal your gut until you find out and remove the cause.  In order for your gut to heal, you will most likely need to uncover any food sensitivities through an elimination diet, remove processed foods from your daily diet, cultivate good stress coping techniques, have good food hygiene, and be mindful that you aren’t over-training.

Stool Testing

fix leaky gutSeriously, how could I do a series on Leaky Gut and not talk about stool testing?!

Consider working with a qualified practitioner to see if you have any underlying gut infection or severe dysbiosis that may be contributing to inflammation.  This is often done through stool testing… not the most fun thing for patients to do as it usually involves collecting several samples over a 3-10 day period.  However, it can yield all sorts of useful information about fungal (including candida), viral, and bacterial infections.  

A good panel should look at three samples and include not just evidence of infection but markers of inflammation, immune activation, pancreatic function, occult blood, and information on the balance of normal gut bacteria.  None of the tests out there are perfect; I find Doctor’s Data to be one of the best.  This type of specialized stool testing is more extensive than the O&P (ova and parasites) run by most conventional MDs, including gastroenterologists.  If a gut infection is found, this needs to be dealt with before healing a leaky gut.

Supplements to Fix Leaky Gut

Once you’ve given attention to diet, infection, eating habits, etc., supplements can be helpful in healing a leaky gut.  Here are some of my favorites to use clinically:

L-glutamine

A dose of 5 grams 2-3 times per day will help feed your enterocytes and keep them healthy.  I like to use a powder of pure glutamine from Klaire Labs.  It takes a lot of caps to reach a therapeutic dose and most contain unnecessary fillers.  Glutamine has been shown to protect the gut’s integrity after surgery (1).  Glutamine is important for the function of tight junctions (these are what keep the cells of the GI tight together, aka not “leaky”) and glutamine deprivation impedes their ability to stay “tight” (2).  Glutamine is very well tolerated; I don’t think I have ever seen an adverse reaction to it.

Colostrum

Cod Liver Oil (CLO)

Good quality fish oil is anti-inflammatory and omega-3 fatty acids have be shown to support good intestinal barrier integrity (5, 6, 7).  I prefer CLO over regular fish oil because of the vitamin A and vitamin D content.  Both of these vitamins have also been shown to support a decrease in intestinal permeability (8).  Carlson’s is a good brand and can be bought at a discount from Vitacost.  It is important that CLO be of very good quality; rancid fish oil that has been treated with chemicals won’t do your gut any good.

Edible Clays

Bentonite clay has been a standby for detox and gut health in the natural healing community for decades.  Other edible clays (diosmectite, montmorillonite, and illite) have been shown to be protective against an increase in intestinal permeability damage from toxins produced by molds (9).  Zeolite, which has properties similar to those of edible clay, can improve leaky gut as well as decrease levels of zonulin.  (Remember, gluten increases zonulin, so edible clays are a good go-to if you are accidentally glutened).  Clinically, I use Terramin, a mineral rich edible clay from California.

Zinc

Suboptimal zinc levels are something I commonly encounter in my practice.  A deficiency can make the gut more leaky (10).  Supplementation with high doses of zinc have also been shown to repair the gut and decrease intestinal permeability (11, 12).  Doses over 15 mg/day should not be taken long term without considering supplementation of copper.

Green tea

Probiotics

If “anti-biotics” are “against bacteria,” then the “pro-biotics” are “beneficial bacteria.” Research on probiotics shows some of the strongest evidence for healing the gut (14).

Intest-gen

Intest-gen is a combination herbal product from the company, Seroyal.  It contains English walnut, rosemary, and lingonberry. These herbs in combination help support the function of the pancreas, a healthy gut lining, good nutrient absorption, and balanced flora.

Avoid Alcohol

Obviously not a supplement, but important because alcohol increases intestinal permeability.  It is a good idea to avoid it completely for a few weeks while healing the gut.

Final Thoughts on Fixing Leaky Gut

There are many other substances that have been shown to help correct leaky gut:  the fatty acids butyrate, propionate and CLA; the amino acid tryptophan; quercetin; and curcumin.  It isn’t necessary to prescribe or take all of these in order to heal a leaky gut.  After the first steps have been taken (removing processed foods and food sensitivities, stress control, checking for and treating gut infections, etc.), I will choose just a few key supplements, individualized to each patient’s need.

fix leaky gutMost of my patients take cod liver oil and probiotics as foundational supplements, so I usually limit my prescription to 2-3 more items for leaky gut. The goal is that all of the supplements should serve other needs of the patient as well.  For example, if a patient is also showing signs of mineral depletion, Terramin will be a good choice for them.  If the patient is struggling with immune function, colostrum is an option.  In a patient who needs to lose weight and to boost antioxidants, green tea extract will be a part of her prescription.

And an all-around great food to add is bone broth. You can either make your own (I think Chris Kresser does an excellent job of explaining how), or get some from Kettle & Fire.

Gut healing nutrients should be taken for 3-4 weeks.  Remember, to keep your nicely healed gut, you’ll want to follow my leaky gut prevention recommendations.

    I have been trying to heal of which I believe to be leaky gut. Fatigue, bloating stomach, swallon ankles and just not feeling up to par. Looking for help on possible life style changes to fix, flatten and change behaviors. Eating right, yoga and working in balance and still seem to have issues. HELP! My friend from claifornia mentioned the following – Ulan nutrition. Looking forward to hearing from you. 20 pounds heavier than I have been since giving birth to my children!

    • Vicki~ I apologize for the delay in response! It has been a crazy month and I missed this. Your experience sounds very frustrating! And, unfortunately, common. You could very well have leaky gut but I suspect it is in combination with a few other things. You might have gathered from reading the blogs that leaky gut often happens in concert with other issues. If you’d like to chat more about working with me one on one to craft a personalized treatment and look at other causes of your imbalances, I do offer 15 minute complimentary meetings or phone calls. You can schedule this online or call me at 720-295-9439

    I have had leaky gut in the past and believe it’s back due to not taking care of myself. It takes me days to have a bowel movement and I’m always bloated. Also my eczema is really bad on my hands. Help?
