These Are the Best 5 Probiotics for Leaky Gut

Last Updated on

Whether you had a discussion with your doctor or you had a friend tell you that it sounds like your exhaustion and digestion problems are caused by leaking gut syndrome, chances are that you’re at this article because you’re looking to find out what you can do to quickly fix your gut health. Trying to figure out what steps you can take to quickly fix your leaky gut syndrome can be extremely confusing, especially because there are so many different perspectives on what works best for healing your gut health.

You may have some people telling you to just drink a lot of kombuchas and you’ll be completely fine, but you have also heard other people tell you that you need to make your main focus eating fermented foods. However, one common answer that all people can agree on when it comes to working towards healing your leaky gut is taking a probiotic supplement.

Taking a probiotic supplement can help to promote healthy healing of your gut, which will also help your body to have an easier time digesting the nutrients that you consume in your diet. Having a high-quality probiotic on your side while you’re fighting against a leaky gut can help to encourage a healthy immune system, prevent Candida overgrowth, balance out the bad bacteria levels your gut has, and help to encourage healthy digestion.

What is leaky gut syndrome?

leaky gut

A leaky gut syndrome is a health condition where undigested proteins such as microbes, toxins, and gluten are passed into your bloodstream. This health condition also goes by another name, intestinal permeability. Those fancy words basically mean that your intestinal wall has been damaged, which has allowed undigested fragments to pass through your intestinal wall and into your bloodstream.

When these fragments enter your bloodstream, it triggers your immune system into action. It also causes parts of your body to become inflamed. If your body has this problem for a long period of time, your body will eventually develop food sensitivities. Some long-term sufferers of the leaky gut syndrome have also claimed that they have developed depression, anxiety, ADHD, nutrient malabsorption, inflammatory bowel disease, arthritis, eczema, acne, and even some autoimmune diseases before they began to get treatment for their leaky gut syndrome.

Most doctors will say that it is going to take some time for you to see results during the beginning stages of your treatment for your leaky gut. However, it will only take a long time for you to see results if you only take a supplement and don’t work on changing your diet. By changing your diet around and taking the right supplements, it won’t be too long before you’re on your way to seeing results.

How do probiotics work towards healing my leaky gut?


Having more good bacteria in your gut will help to cut down on the amount of bad, harmful bacteria that lives in your system. By consuming good bacteria (probiotics), you will help to reduce the number of bad bacteria that’s in your system, reduce the amount of inflammation in your gut, and help to create a healthier environment in your body.

Is taking probiotics safe for my leaky gut?

Yes, taking probiotics is safe for your leaky gut. However, if you are someone who has SIBO (small intestine bacterial overgrowth), you already have an excess of good bacteria in your gut. Adding in even more bacteria in your gut can cause your gut to become overpopulated, which will make your excess good bacteria turn bad.

When you first start taking probiotics, you may experience some cramping, bloating, and/or diarrhea for the first few weeks. Don’t worry, this is totally normal! Just try thinking of it this way: if you are taking a probiotic with a really high count (typically over 50 billion), your body is going to take a small period of time to adjust. Just in the same way that you wouldn’t try fitting fifty people into a ten-seat bus, your body is going to need a little bit of time to get used to the increased number of healthy bacteria entering your system.

What strains of bacteria are the best to take for my leaky gut?

While there are countless different strains of bacteria available on the market, the strains listed below are best for gut health:

  • Lactobacillus casei- This strain of bacteria helps to support the growth of acidophilus in your gut, while also helping to reduce the effects of intestinal permeability.
  • Lactobacillus Plantarum- You can find this bacteria in your saliva, as this bacteria works towards fighting against bac bacteria entering into your body via your mouth. This bacteria also works towards preventing Candida from overgrowing and work towards preserving nutrients, vitamins, and antioxidants found in the body. Additionally, Lactobacillus Plantarum is responsible for producing l-lysine, which is an amino acid that helps to increase the functioning of your immune system.
  • Bifidobacterium longum- Bifidobacterium longum is responsible for the for the production of biotin, which is a B vitamin that assists in the control of Candida. Basically, this bacteria strain helps to create biotin, which then helps to stop Candida from growing into more complex, harder to kill strains.
  • Bifidobacterium bifidum- This bacteria strain can be found in the vagina and the colon and is responsible for the production of B-complex vitamins. It also helps to fight against the production of histamine, which is the main chemical in your body that starts allergic reactions.
  • Lactobacillus acidophilus- This is the strain that you will most commonly find in probiotic supplements and does a lot to help out your immune system. You can find the Lactobacillus acidophilus at work in stimulation of your immune system, the production of B vitamins, the production of enzymes that help to increase nutrient absorption and calcium absorption.
  • Lactobacillus rhamnosus- You can find this strain in your intestines because it does a wonderful job of surviving in acidic environments. This strain works to help build a healthier immune system for your body by working with white blood cells to find against bad bacteria.

VSL #3 Probiotic Medical Food

The supplements from BSL #3 contain 112.5 billion live bacteria that come from eight different bacteria strains. This is the most expensive supplement on this list, but we included it in this list because there were so many people who recommended the supplement for serious damage control for the leaky gut syndrome and because it has such high ratings on internet reviews.

As a side note, the most common complaint that a lot of people had about this probiotic supplement was that they had to keep it in the fridge at all times. This may not be a product that you want to get your hands on if you are someone who is constantly traveling around and don’t always have access to a fridge or if you are someone who doesn’t always have access to keeping your supplement in a cool place at all times. Keeping this probiotic in a cool setting is important because if you don’t you will kill off the good bacteria. This can lead to an unreliable product if you don’t take the time to make sure that you’re keeping the bottle in a cool place.

Don’t worry, you don’t have to worry about this with all probiotics! Most of the time, the more expensive supplements are the ones that you have to keep in the fridge. The supplement will always have some sort of identification on the bottle to let you know that you need to keep it cool, so don’t worry if you don’t have constant access to a fridge!

How long do I have to wait until I see improvements?


As we talked about earlier, there are two very important steps that you need to take before you will start seeing results in your leaky gut syndrome: changing your diet and taking supplements. The length of time that it’s going to take for you to be able to heal your leaky guy depends on several factors, such as how several your intestinal permeability is, how healthy your diet is, how well you are managing your stress levels, and if there are any other problems that you are having with your gut health (such as Candida overgrowth). All of these factors ultimately end up coming together and affecting the overall health of your gut.

Some users may start seeing improvements in the gut health after only one month of taking probiotics, while other users may start seeing results after two years of being committed to improving their gut health. It really all just depends on how severely damaged your gut is, so results will vary for each unique case. Even after you start seeing results, you should continue to take probiotics and consume naturally fermented foods to continue improving your gut health.
