It was time I put together an all about Just Thrive Probiotic post because I’m getting comments and questions on it now daily.

A few weeks back, my daycare texted all parents late morning saying, “My baby (not using names in this post) has thrown up 11 times in the past two hours and is now dry heaving.” This escalated and the baby ended up in the hospital, dehydrated with a Norovirus and Sapovirus diagnosis. 

I asked if anyone else got it. She said, “Yes,” they all did – including every other parent and child at the daycare.

Of course I was paranoid everyone at our house would tumble like building blocks, but we escaped it. No one got it! 

Fast forward to a week later when my daycare texted me again. This time, she was telling me about her doctor in a nearby town who mentioned my work (it was super random, and I have no idea who the doctor is). The doctor asked her, “Did Sarah’s family get this sickness, too” My daycare replied, “No.” And the doctor said, “Yep, she’s probably using a probiotic of some sort and ti’s doing its job, keeping the gut working as it should!”

I about fell over – Ryan, too. A doctor who has heard of my work and had good things to say about a high-quality probiotic.

Can’t make this up, guys!

Over the years, I have tried many different probiotics. I have written a lot about them, with regards to different digestive conditions. And I have selectively taken and then not taken them. 

But after Expo West 2019, I completely moved our entire family over to the Just Thrive Probiotic and furthermore, chose to only align with them from a probiotic recommendation standpoint for those who read A Gutsy Girl

Other FAQ’s for the Just Thrive Probiotic

Just Thrive Probiotic benefits #probiotics #supplements #guthealth faq

I have SIBO, how will Just Thrive help me?

One of the strains in Just Thrive has been used in Europe as a prescription for SIBO for decades. The strains in Just Thrive are gut commensal organisms, meaning that every living human and animal has a binding site for these strains.

They also have a published human clinical trial showing our probiotic is healing Leaky Gut, so there are less toxins leaking into your bloodstream.

Just Thrive has the ability to produce up to 25 specific antibiotics when they sense pathogenic organisms and also create compounds and nutrients that feed naturally occurring beneficial bacteria.

Can Just Thrive treat candida in the gut?

They have seen great results with Candida as in most cases it drives out the yeast and helps replace the real estate with good bacteria. This is an important factor in ensuring that the candida over-growth doesn’t simply reoccur. Additionally, candida over-growth is a sign of a weak immune system and or dysbiosis and since the spores improve both, they certainly help with candida.

Can I use this probiotic if I have a histamine intolerance? 

Yes. It certainly is a great probiotic option for people with histamine intolerance because the spores do not produce histamine, unlike many lactobacillus species.

Reacting to histamines from foods is a fault on the part of the pattern recognition system and the Treg system (regulatory T cells that modulate the immune system and prevent autoimmune disease). The spores modulate both to shift the body from an inflammatory Th2 response to an adaptive Thi1 response.

The strains in Just Thrive are found in the soil, but only in their dormant state. The gut is their home and they only go into their live, vegetative state when they arrive in the gut. 

What are the ingredients?

A proprietary probiotic blend 500 mg, 3 billion cells of the following: Bacillus indicus HU36, Bacillus coagulans, Bacillus clausii, Bacillus subtillis HU58, cellulose (hypoallergenic plant fiber prebiotic), and hydroxypropyl methyl cellulose HPMC (vegetable capsule). You can learn more about Probiotic Strains and Species HERE.

Do I need to refrigerate this probiotic?

No. Also, a good probiotic should not need to be refrigerated. See THESE 8 probiotic myths.

Will taking the Just Thrive Probiotic help when I’m on antibiotic?

Yes. According to Joanie Blaxter, “Ever been told to avoid taking an antibiotic and probiotic at the same time because the antibiotic kills the probiotic? NO LONGER TRUE. Spore bacteria, like the proprietary strains in Just Thrive, are protected by their outer spore shell from the killing effects of antibiotics.”

In contrast, conventional, non-spore strains (Lacto, Bifido, Streptococccus, etc.), do not have this same protection.

So Just Thrive Probiotic is better than MegaSporeBiotic? Did Kiran Krishnan help develop both of them? What is the difference in them?

Megaspore is Just Thrive’s sister company and it’s only available to practitioners. Just Thrive is the retail version of Megaspore. They work extremely close together. All of the research and studies are conducted with both products. Just Thrive has the exact same 4 key strains as Megaspore in the exact same amounts.

Both products have the game changing antioxidant producing strain, Bacillus Indicus HU36. The only difference is Megaspore has a small amount of
the strain, Bacillus Lichenformis. Bacillus Lichenformis is a strain that Kiran Krishnan felt should be taken under a doctor or trained professional’s care. It
produces the antibiotic bacitracin, as well as some digestive enzymes.

Just Thrive is available to everyone where MegaSpore can only be obtained through a practitioner and is a bit more expensive.

Will this probiotic help if I have C. Diff?

The Bacillus Strains found in Just Thrive have been clinically proven in a double blind placebo, human clinical trial to heal leaky gut, which you will likely have after battling C. Diff. These strains are very different than most probiotics, kombucha, enzymes, etc.

They arrive 100% alive to the gut and begin healing by killing off toxins and pathogens and rebuilding healthy bacteria. They colonize and stay in the gut for 21-27 days.

Learn more about C. Diff HERE.

I heard I should take my probiotic without food. Is this true? When is the best time to take Just Thrive?

There is no best time to take Just Thrive, but they recommend taking it with your largest meal. Food will help the strains get into their live, vegetative cell state quicker. By the way, this is also why it’s so easy for me to get into my children’s diets – I can just sprinkle over their food (without them even knowing) – ahem, Mac ‘n Cheese!

Does Just Thrive cause die-off symptoms? Or flu like symptoms?

Although rare, some people do experience die-off effects when starting Just Thrive. It usually happens within the first few doses, so if you experienced any symptoms right after starting then it could possibly be die-off. What they recommend is lowering the dosage to either ¼ capsule or half a capsule a day until the effects wear off.

Although unpleasant, die-off effects are a sign that Just Thrive is going to work eliminating your bad bacteria, while feeding the good bacteria. Essentially, it means Just Thrive is working! The overwhelming majority of people that reduced their dosage did great and were grateful they didn’t stop taking it. Give it a full 7-10 days and you should have no problems as your gut starts healing.

HERE is more information about what to expect what starting probiotics.

How long should I be on Just Thrive?

The strains in Just Thrive were strains our ancestors consumed on a daily basis in the food they ate, the water they drank and the dirt they lived in. But they do have a 21-27 day lifecycle in the intestines so if you take the product every day for a few months, you can go to a maintenance dose where you take it every other day or every third day if you’d like.

We continuously assault our gut on a daily basis with our food, environment, habits, etc… So we need some measure of daily protection like Just Thrive to ensure we stay healthy.

Is it just me, or does Just Thrive seem more expensive than other probiotics?

Just Thrive is a pharmaceutical grade supplement. It is comprised of bacillus endospores which have been in the pharmaceutical market in Europe and Asia for over 60 years.

They are the first and only retail product on the market with the strain Bacillus Indicus HU36, which produces RDA levels of crucial antioxidants right in the intestines where they are immediately absorbed. It is this strain that the researchers felt did most of the “heavy lifting” in their published Leaky Gut study. Getting exclusive rights to this strain was extremely costly.

They currently have 9 other human clinical trials being conducted on the product. There is no other probiotic on the market that is doing anywhere near the number of human clinical trials on their product. Most companies do petri dish or at best animal trials which are much less expensive than human clinicals.

Because they want their product in the hands of as many people as possible due to the effectiveness, they launched the product at much less of a profit margin to the company than virtually any other supplement they know of.

Questions for All About Just Thrive Probiotic #SIBO #probiotics #guthealth

I cannot afford to take Just Thrive daily. Can I take it every other day and still get the same results?

They recommend taking it daily for at least 2-6 months, depending on what level of intestinal dysbiosis you are dealing with.

If you are basically healthy and don’t have a lot of digestive issues, you can try and take it every other day and see how you feel.

Our ancestors consumed these strains on a daily basis so they are meant to be consumed daily, but that’s when the strains were found for free abundantly in the environment. You are better off taking it every other day or every third day rather than taking a probiotic that simply doesn’t survive the stomach acid and make it alive to the intestines. Just Thrive colonizes and have a 21-27 day lifecycle in the intestines so if you take the product every day for at least a few months, you can go to a maintenance dose where you take it every other or every third day and keep your gut healthy.

Our guts are being attacked daily with the foods we eat, our environment, habits, etc. Just Thrive is daily protection to keep you healthy.

Does heat affect Just Thrive? Does it expire?

Just Thrive is heat stable up to 455 degrees. You can open the capsule and bake with it or put it in food or drinks. The current expiration is 4/2023. The spores are dormant in the bottle until ingested.

Once the spores get to the intestines, they come alive and have the ability to read the microbiome and directly eliminate unfavorable and overgrown organisms. They recondition the gut as they shift the balance of good and bad bacteria. Bacillus endospores are “gut police”, knocking out the bad and bringing out the good!

Is Just Thrive safe to take while pregnant and breast feeding? 

Just Thrive is super important to take while pregnant and breast feeding. Mothers pass their immunity and microbiome to their children. The spores have the ability to modulate the microbiome to help optimize it and improve moms immune system as well. This way she avoids getting sick, she has less inflammation, she is making important antibodies that she will pass onto her child to keep him/her healthy.

Just Thrive has studies showing our strains created a 30% favorable shift in the health of the Microbiome so if mom has a healthy microbiome, she will pass that healthy microbiome on to her baby. 

I have an out of whack gut and have never been able to tolerate any form of probiotics? Would Just Thrive be able to help me?

The strains in Just Thrive are much different than the vast majority of probiotics on the market today. Our strains are natures true probiotics and strains our ancestors consumed on a daily basis but are depleted in our sterilized, overprocessed environment. Our strains are gut commensal organisms meaning every living human and animal has a biding site for them. They belong and only become alive in the gut.

Is Just Thrive safe for infants or children under 3?

The company encourages you to ask your doctor if it would be ok to put your baby on probiotics because as you know, we are not doctors and cannot give medical advice.

That being said, these strains are perfectly safe for healthy newborns as well. In fact, our microbiologist who has worked with these strains for years had his new born daughter taking the powder a few years go- he would sprinkle a bit of the powder from our capsules on his wife’s nipple while the baby was nursing so that his daughter could get some of the strains. The minimum age of 3 that’s on the label is there for choking hazards with children.

The company has, however, listed that the contents can be opened and mixed with food. You can sprinkle the contents in any food or drinks, it is heat stable up to 455 degrees so you can even sprinkle some in a cookie, muffin or your favorite recipe.

I would start out with a quarter of a capsule for a newborn to 6 months old as long as it’s ok with your doctor. If the child is older than 6 months, a half a capsule is a good dosage. Children 3 and older, a full capsule is the ideal dosage.

I have a severe corn allergy, is Just Thrive safe for me to take?

As always, consult your doctor before starting Just Thrive. Dextrin, a derivative of NON-GMO corn is used as a carrier in the probiotic strains.

It doesn’t cause problems for most corn allergies, but if yours is severe, please use caution and consult your doctor. 

Can Just Thrive help with chronic bacteria infections for example, in the vagina and UTI infections?

Yes, we see this all the time. Any chronic infection in mucosal tissue like the urinary tract, vagina, sinuses, lungs, etc. can be helped and controlled by modulating the immune response in the gut mucosa. There is something called the “singular mucosal system” which shows that changes in the gut mucosa are almost instantly seen in other mucosal tissue like the vagina or upper respiratory tract.

In fact, clinical studies have shown the spores to be effective in preventing infections like chronic UTI’s and chronic upper-respiratory infections.

If, however, you are looking for a UTI-specific product, Just Thrive has one, UT123 [HERE].

    1. Hi! Here is some information from PaleoMom’s blog: “Gastritis, is the inflammation of the stomach lining and Just Thrive definitely helps with all sorts of inflammation. Bacillus Coagulans is a well studied strain that has shown profound effects on inflammatory conditions and then Bacillus Indicus produces anti-oxidants such as astaxanthin and zeaxanthin that are very well knows as fighters of inflammation.” And on On Jan 16 in an email to her readership PaleoMom said: “I have been taking Just Thrive Probiotic ( for about 9 months now and I am very happy with the results. Not only did I notice improved digestion, but the mild hormonal acne that I have always had has disappeared! I was impressed enough to get my now 12-year old taking Just Thrive too, which also helped her acne as well!” Hope that helps!

  1. I just bought this but wondering if it will effect my GERD symptoms at all but I was sold once I read about the skin improvements (I have Melasma) and the chronic UTI help so worth a shot!

  2. Hi… thanks for all the work you do…
    Ehmmm… I was just wondering, what can some of the negative side effects of Just Thrive be?
    Have you any experience with JT and eczema on kids (+5 yrs.)?
    again thank you…
    Best wishes

  3. Hi there,

    Has anyone else you know had similar results with this probiotic? As in, avoiding sickness bugs. School is a nightmare for things circulating and we could use the support!


  4. I gave it a chance and started taking it, but after a few days I realized they weren’t helping :(. I had the same problem as with other probiotics. I started feeling more bloated, heavier, constipated and my skin were smoother and my mood very depressive. I cried for anything.
    Does anyone knows why?? I feel like my body has had enough probiotics and hate all of them x)
    ‘ve been suffering from candida from long time ago although my immune system works fine. I also eat always real food, no sugars, etc. I don’t know yet if I have SIBO. But I’m 24/7 bloated.

  5. I’ve taken Thrive now for a few months but still having digestive issues- I thought I read that I could take 2 during times of severe digestive distress… have you heard that?

  6. Hi there, enjoying your posts so much! I wanted to ask; do you consider antibiotics necessary for sibo/sifo? My doc wants me to take paramomycin and grisefungine… what do you think of that?


  7. Hi Sarah, how do we purchase just thrive, do you have a link that benefits you, a coupon or discount that you can share? Ready to try this now! ☺️

  8. Hi, Sarah
    I bought Just Thrive in order to help treat SIBO but was surprised to see that hypoallergenic plant fiber prebiotic was one of the ingredients. I know I am being overly finesse but I thought that prebiotics have to be avoided during SIBO treatment. Thanks, Travis

    1. Yes, there is. It contains Acacia fiber. The issue with most prebiotics is that they feed both bad and good bacteria. The Just Thrive Probiotic includes a precision prebiotic that will only feed the good.

      1. I thought SIBO was believed to be an overgrowth of good bacteria, ie. too much of a good thing , so why provide more good bacteria?

  9. I have histamine intolerance and im pleased to hear the strains in just thrive dont produce histamine. I wondered thou if it would be okay to continue taking histamine degrading strains that im taking at present. Bifidobacterium infantis, Bifidobacterium bifidum, Bifidobacterium longum, Lactobacillus salivarius, Lactobacillus plantarum, Bifidobacterium lactis and Bifidobacterium breve. Could i use just thrive alongside the probiotic im already taking?

  10. Hey Sarah

    I have shown my DO this probiotic and while she said it was good she said it wasn’t enough diversity for my gut considering I have ulcerative colitis. What is your opinion on that? To me it feels like when I take thrive it does help but then sometimes I don’t notice anything. It could be because I don’t take it consistently enough but I think that’s because I have been worried it’s not enough for me.

    1. Hi! Above all else, listen to your doctor. But when it comes to listening to your doctor and how YOUR body is responding, definitely question your doctor and have a conversation about it.

  11. Hi- I am on Xifaxan (2 pills/day) for the next few weeks and wasn’t sure if I should take a probiotic or not during the treatment. If I start taking Thrive, when would be the best time of day? Away from Xifaxan? Also I have perioral dermatitis flaring right now…haven’t had a flare up in over 5 years

    1. Hi Lindsey – you should absolutely work with your doctor on this one. While ON Rifaximin, I personally did NOT use any probiotics. But you might need to. If so, just start slow and go (like 1/2 capsule at a time).

      1. Thanks! Did you have any skin issues while on Rifaximin? My PD is really flaring and I haven’t had any issues for years.

  12. hello! would this probiotic help with laryngopharyngeal reflux (silent reflux)? I have been having very extreme flare ups recently and am desperate for a solution (while also trying to avoid acidic foods and other things I can do at home). Thanks!

  13. Hi Sarah 🙂

    I’m just wondering if these Probiotics alone might get rid of sibo… though I have extreme bloating (and constipation) my sibo test results came back only slightly elevated. Do you think something like this may balance my bacteria?

  14. I’m trying to wean myself off of PPIs (long-term use), but I’m not there yet. Can I take Just Thrive probiotics while on PPIs?
