The Just Thrive® Process

Once Just Thrive® enters the digestive system, it has been found to perform many critical functions, including enhancing the immune system; both increasing digestion and absorption of nutrients from food, and producing important functional antioxidants.

The strains used in Just Thrive® have been proven to survive the gastric system 100%! Once they arrive alive in the intestines, they actually have the unique ability to read the microbial environment. In fact, these strains have the ability to:

  • check markSurvive the harsh conditions of the stomach 100%
  • check markIdentify pathogenic organisms (and once they do this, they produce natural antibiotics to help kill off the bad bacteria…)
  • check markCompetitively exclude the overgrowth of opportunistic organisms
  • check markCreate compounds and nutrients to feed the good bacteria in the gut

This approach is the most effective way to achieve diversity in the gut and is why customers are seeing such dramatic results with Just Thrive® Probiotic!

Just Thrive® contains gut commensal organisms, meaning they belong in the gut (and find a binding site in the intestines), and these strains have a 21-day life-cycle in the gut, while most other probiotics simply pass through like food.

Created with a patented strain called Bacillus Indicus HU36®

Bacillus Indicus HU36®, produces antioxidants/carotenoids (the nutrients that give red peppers and tomatoes their color) in your intestines where they can be best absorbed by the body, making it one of the most absorbable forms of antioxidants on the market.


Along with Bacillus Indicus (HU36), the spore strains in Just Thrive® are the only on the retail market clinically proven to heal leaky gut within just 30 days!

Likes: Delivered straight to my home and works wonders.
Improvements: Nothing! Very satisfied.
Miracle worker!

I have been to the doctor several times the last couple of years with excessive bloating and bathroom issues. No one could help and could not find anything wrong with my stomach/blood work. I finally gave in and spent the money on quality probiotics from Just Thrive and after about 30 days my stomach has never felt better. No more bloating or stomach issues at all. So grateful I found these probiotics.

NPS score:
Likes: Works!
Improvements: Price is very expensive
The only one that’s ever worked!

I’ve been taking probiotics for years for overall health but also to help my constipation. I found out about Just Thrive from their podcast episode on His & Her Podcast with The Skinny Confidential. Their science behind their products was very impressive I had to give them a try! I’ve been taking them for over 2 months now and will never go back to other probiotics! These have been the only ones to consistently alleviate my constipation issues with no stomach pains.

NPS score:
Likes: Made a huge difference in microbiome
Improvements: Nothing
A probiotic that actually works

My wife and I have tried a few different probiotics over the years, but this is the first one where we can actually tell there has been a change in our gut microbiome. Now our whole family takes it and we can't recommended it enough.

NPS score:
Likes: How it is restoring 15 years of gut dysbiosis
Improvements: Maybe having some more
I’m impressed

At a complete loss with gut dysbiosis for years I have attempted to take my health into my own hands. I listened to a podcast with Dave Asprey and two members from the Just Thrive team. Historically speaking probiotics have never worked for me and it’s been a complete waste of money. That being said, listening to them cite their research, information, and how they differ from the competition I was ready to take the plunge. I understand that if you want a quality product you won’t be paying bottom prices. I’m glad I didn’t hesitate to purchase once I learned. I’m still on my first bottle and definitely going through a healing phase. I have had some a fair number of break outs on my face, but my stomach has been feeling less inflamed already. I’m familiar with detoxing and the herx reactions. The ability to not feel like a beached whale after eating anything is remarkable. I’m sold and a believer in this brand. I’ve already sent my friends who are looking for a probiotic this product too.

Frequently Asked Questions

A probiotic is a live beneficial bacterium that has adapted to survive in the human digestive system. In turn, it provides a health benefit to that person. By definition, to be a true probiotic, it has to be an organism that has evolved to become exposed to a human host through consumption (typically via the food supply); have the capability to naturally survive the harsh environment of the stomach, and have the ability to effectively colonize in the intestines where it provides health benefits. Any bacterium that is unable to naturally survive the harsh environment of the stomach and upper digestive system cannot be a true probiotic.

Studies have shown that the 100 trillion bacteria cells in the digestive system have a profound effect on overall health and wellness. They play a critical role in the digestion and assimilation of nutrients from food. They also protect the body from harmful organisms by strengthening the immune system. They modulate the immune system to help prevent undesired immune responses like allergies, autoimmune, etc. Recent studies also have linked a healthy gut flora to better emotional health, weight control, sexual function, and improved cognitive function.

Unless you consume specific fermented foods, probiotics are no longer naturally available from food. The food production systems are sterilized in an effort to extend the shelf-life of processed foods; usually three to nine months. This eliminates most of the beneficial bacteria that normally would have been available from the food source. Our ancestors ate and lived off the land. They were exposed to a significant number of environmental bacteria on a daily basis – this includes bacillus spores (those found in Just Thrive®). This is nature’s true design for daily probiotic exposure. Due to the sterilization process, beneficial organisms are no longer naturally available in traditional food sources and so have to be supplemented.

Absolutely – Just Thrive® is a critical, daily nutrient and will not interfere with the vitamins you take. In fact, it can be argued that Just Thrive® is even more important than your daily vitamin as Just Thrive® is your only source of these key probiotic strains whereas vitamins can be found in a variety of foods and supplements. Just Thrive® is a necessary nutrient that is not found in the daily diet.

Yes. From processed food and environmental toxins to antibiotics and alcohol usage, the digestive system and the beneficial bacteria that reside there face daily assaults. A daily probiotic like Just Thrive®, which is designed by nature to be a true probiotic, is the best protection you can possibly provide for your body. In addition, your immune system is designed to receive daily stimulation in order to remain primed and ready for action, this is why over 70% of your immune system is found in your digestive tract.

Just Thrive® is the only probiotic available comprised of four (4) key strains of nature’s own design for a true probiotic. The bacillus strains found in Just Thrive® are abundant environmental organisms that have evolved to be consumed by humans on a daily basis and then thrive in the digestive systems. Once there, they perform critical functions, such as the development of the immune system; reduction of inflammation; digestion and absorption of nutrients from food, and the production of important functional compounds, like antioxidants. Just Thrive® is the only product on the shelf to contain the patented Bacillus Indicus HU36®, a strain that produces high levels of antioxidants. Once ingested via the intestines, Bacillus Indicus HU36® becomes an important source of daily antioxidants.

Simply put, Just Thrive® is a TRUE probiotic by all scientific definitions and over 95% of other products on the market just are not probiotics.

A patented strain in Just Thrive® called Bacillus Indicus HU36® actually produces a variety of antioxidants in the digestive system right where they are best absorbed by the body. Studies have shown that supplemented antioxidants do not effectively survive the stomach and so the actual absorption rate is low when taken as a supplement by mouth. With Just Thrive®, however, the body becomes a super-antioxidant factory right in the digestive system at the site where these important nutrients are absorbed. It’s right at the site of absorption where CoQ10, alpha and beta carotene, lycopene, lutein, astaxanthin and zeaxanthin are produced!

Antioxidants protect the body from the daily onslaught of harmful and toxic chemicals and compounds. Oxidation causes significant tissue damage at the cellular level and antioxidants protect against this damage. Maintaining high levels of antioxidants in the body has been linked to lower incidences of cancers, heart disease, diabetes, etc.*

Because Just Thrive® is such a potent product, many users feel the difference in just two to three dosages. If you tend to have gastrointestinal disturbances, you should see a calming effect on your system. If you tend to have irregular bowel movements, you should experience some improved regularity. For people without evident digestive issues, just like you take a daily multivitamin but don’t necessarily FEEL the benefits, you can be confident knowing that your overall health is improving by a daily dose of Just Thrive®. In general, users have reported more energy, better sleep and just an overall “good” feeling. Your entire system benefits when your gut is healthy!
