best probiotics for weight loss

5 Absolutely Best Probiotics (Weight Loss, Leaky Gut, and More)

With more than 65% of the American population being overweight, it’s no surprise that weight loss is a primary goal for many adults.

Losing weight can be a struggle, especially when the latest fad diets and new exercise programs are marketed so heavily. More often than not weight loss pills or other supplements just don’t work.

Either they spark some weight loss, followed by gaining more weight back, or they end up being a waste of money. In some cases suspect weight loss supplements can be damaging to your health.

Bottom Line Up Front: In a hurry? Just need a good recommendation? My favorite probiotic for weight loss is Renew Life Ultimate Flora Extra Care, which is currently available at this listing.

How Can Probiotics Help With Weight Loss

According to a recent meta-data analysis published in the International Journal of Food Sciences and Nutrition, those seeking to lose weight may benefit from consuming probiotics. Most people are likely familiar with probiotics as the beneficial bacteria found in common foods like yogurt and fermented foods. Some general health supplements will also have probiotics added to them.

While the benefits of supplementing probiotics has been well-known for some time, research has found that it’s advantages to the digestive system positively affect fat loss.

There are two types of healthy bacteria present in the gut microbiota, bacteroidetes and firmicutes. These two gut flora bacteria are vital for a healthy digestive system and also seem to affect body weight. Studies done on both humans and animals have shown that individuals that are overweight have different bacteria flora than those of a healthy weight.

People with a higher ratio of firmicutes to bacteroidetes were overweight, with weight of participants lowering to normal as this ratio evened out.

Another study done on mice showed that transferring gut bacteria from an overweight mouse to a healthy mouse caused the lean mouse to gain weight. A combination of these types of studies lead researchers to the conclusion that addressing gut bacteria levels is an important part of achieving and maintaining a healthy weight.

Interestingly enough, weight loss studies done have shown women to be susceptible to weight loss induction from probiotics than men. It can be agreed both genders can benefit from probiotics, however.

Probiotics have been proven to be helpful in weight loss in two ways – inhibiting fat absorption and helping to stabilize gut bacteria ratios. Good bacteria, like Lactobacillus, found in probiotics cause the body to release an appetite-suppressing hormone and increase protein levels.

Both of these activities lead to burning body fat and slow fat storage. All in all, when your digestive system is working properly you will lose weight since your body is able to better absorb nutrition and remove waste.

While more research is needed to determine just how powerful probiotic supplements can be for weight loss there is no reason to not add it to your diet. Their numerous other health benefits, along with fat burning and digestive health support, is plenty of reason to check out one of these top 5 products.

What About Leaky Gut? Best Probiotics for 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 GOOD Bacteria from Probiotics Can Help

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.

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.


Question: What are the health benefits of taking probiotics?

Answer: “Probiotics help your body stay healthy by replacing or eliminating the bad bacteria with good one. Probiotics are most often used to maintain the health of the digestive tract.  The good bacteria are important to keep the digestive system in balance and to help the body’s system for filtering out waste products, chemicals, and toxins. Probiotics can also modify our body’s pH; the proper pH level will reduce the ability of pathogens to settle and it is of crucial importance for maintaining perfectly good health.” John Bale, Quora

Question: Are Probiotics Safe for Leaky Gut?

Answer: 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.

Question: So What is the Best Probiotic for Leaky Gut?

Answer: Coincidentally, Renew Life Ultimate is ALSO great for Leaky Gut (not just weight loss). It contains all of the key bacteria strains mentioned earlier + is a trusted brand with a long history in the market.

The Final Thought on Probiotics

Probiotics may not be a magic weight loss cure, but they will help you achieve your weight loss goals. Like all supplements, not all probiotics supplements are as powerful as others so it’s important to carefully research a company prior to purchasing.

These 5 options featured are all from reputable brands that strive to produce the most potent, beneficial gut health products currently available. As a reminder, my top recommendation is Renew Life Ultimate here.

Keep in mind that you will only see optimum weight loss results from these probiotics when used in combination with an improved diet rich in whole foods and maintaining regular exercise.
