Culturelle’s Lacto GG Research & Health Facts

Lactobacillus Rhamnosus gg is an extremely well researched probiotic strain. It was patented in 1985 and there have been numerous studies proving more than 44 health benefits of this good bacteria.

Lactobacillus gg, also known as Lactobacillus Rhamnosus gg, has extremely good intestinal wall adhesion and thus considered a good probiotic for clearing the way for your body’s native friendly bacterial strains.

This probiotic is best for stimulating the immune system, fighting allergies and helping people have fewer sick days. Additionally it also has some digestive benefits for those with digestive issues like IBS and constipation.

    #1 Lactobacillus GG Supplement

    Culturelle contains 100% Lactobacillus Rhamnous GG…that is this only probiotic strain it has!

    This probiotic is optimized for improving immunity. And this supplement also has L. Rhamnous GG’s allergy fighting and digestive benefits.

    Culturelle is one of the first mass market probiotics…so there are likely 10’s of millions of boxes sold since the company was founded years ago.

    1. michele says:

      Hi, can you tell me if the lactobacillus gg is used for constipation , I wanted to purchase the culturelle but i noticed most people complaining of diarreah and i dont want to constipate myself since i suffer from constipation periodically.

      • evan says:

        Yes it can induce constipation in the short term (for less than a week), but this happens because your probiotics have been shown to directly & indirectly kill pathogenic bacteria.

        When the bacteria die, that waste needs to be removed (more waste to poop out). Also, it’s possible that these dead bacteria can cause irritation. But, beyond a week or two, probiotics WILL make your more regular.

        If you accept that health issues take time to develop (often times years & years), I think it makes sense that it might take more than a week to get back to regularity.

        See why probiotics have side effects.

    2. michele says:

      If culturelle lactobiacillus gg inducees constipaton how is that cleaning out anything. I suffer from constipation so i guess the lactobacillus is not for me.

      • evan says:

        I have never experienced constipation from probiotics.

        Research shows this strain helps with constipation, but your body may time to adjust, and your body is unique – our experiences will likely be different!

        If you would like some more instant relief you can try a teaspon of epsom salts dissolved in water – just stay near the toilet!@!@

        There are a variety of “side effects” as well as benefits…but ultimately these “side effects” are your body cleaning itself out.

        For example, in clinical research lactobacillus gg has been shown to:
        -reduce constipation
        -stabilize intestinal barrier function
        -reduce IBS symptoms

        But sometimes, in the short run, lacto gg can cause people to get constipated, or give them diarrhea.

        This is because in the short term, as the new probiotics fight for space in your body, there may be diarrhea or constipation…but if you were to take the probiotics for ~9 months then you’re digestion would likely improve significantly.

        If you zoom out and look at the big picture, having healthier probiotics in your body will normalize digestion in the long run. You will have less constipation, diarrhea, bloating, gas, etc.

        But in most cases, poor elimination is linked first and foremost to not drinking enough high quality water.

        A 200lb person needs 100ounce of clean, filtered, water with a pinch of sea salt, every day! Tea, soda, milk or anything like that does not count…your body needs that much every day.

        Since we are 70% water, if we are dehydrated literally every part of us is affected negatively…including our digestion and elimination system!

        take care,

      Can you suggest a good probiotic without soy and tree nuts? I wanted to take pearls since they are easy to take with me and only one per day but they have soy lecithin then i wanted to take dr. ohirahs probotics but i have read they have carageenan in their formula which i read is not healthy. what do you think?
      thanks for your help.

      • evan says:

        Culturelle is hypoallergenic, which means it is free from all common allergens such as soy, wheat, yeast, dairy, eggs, dairy and corn. Try that one & see how it works for you.

        I believe RenewLife also has some hypoallergenic probiotics that I like.

        As far as Carrageenan be toxic, depending on how it is processed – it sounds like it could be. Thanks for sharing that.

    4. Jeannette Jones says:

      Hi, can you suggest which probiotic strain is the most effective (or should be in a complex) in preventing and treating respiratory issues? My husband has asthsma, then contracted pneumonia, then bronchitis, then pneumonia again. We have been using probiotics to treat a lot of these, but are there one or two strains in specific that we should look for?

      • evan says:

        Hey Jannette,

        Here are a few strains:

        Also, please consider the following.

        I would strongly suggest that while probiotics can help, other lifestyle factors can have a much stronger effect on respitory illnesses.

        You can Google Candida Respiratory Problems for example.

        Another thing to check would be food intolerance (eg. gluten, eggs, milk, synthetics dyes), how much sugar you consume, as well as a number of other factors.

    5. Daniella says:

      Excellent article, people need to become aware of the benefits of probiotics and the damage that antibiotics do to our bodies.

    6. Alice Chong says:

      my son is 10 yrs old, he has ezcema since baby. allergy to dust mite shown by blood test.
      under control after I had noticed that he can’t take some food too. but his skin is very dry
      and he scratches often, i put him with emu oil.
      i let him take lactogg for 3 days already, but since day1 till now, he started to have red spot
      with tiny yellowish liquid in the centre of it on his body, getting more and bigger,
      he said it’s itchy. Why is it so? should i stop giving him lactogg ?????

      • evan says:

        Hi Alice,

        Great job on getting the blood test for allergens – great source of actionable information.

        I would reduce the dosage. Say, 1/2 as much and see if the symptoms decrease (see side effects of probiotics). Your poor son is likely experiencing a detoxification reaction – our skin is a powerful detoxification organ.

        Have him drink lots of water, and make sure your son is getting lots of rest (bed before 10pm) & has a minimum of stress. And give him extra hugs & love!!

        good luck & let me know how it goes Alice.

    8. cathy says:

      My 4 month old son has eczema and I was advised to look into a probiotic LactoGG for him. He does have a dairy allergy that we know of, maybe more. Which product would you recommend for my baby?

    9. christine says:

      2 years ago my hubby has oesphagus ulcer. Dr prescribed LactoGG .besides the nexium medicine before and after endoscopy. He is having the ulcer symptoms again . He started taking nexium and Lactogg once a day and his condition is much better now.
      Please advise me on the following:

      Is there any negative effect to take LactoGG on a long term basis, for example for a whole year or even for the resit of his life ?
      Secondly, I would like to know is it better to take LactoGG before meals, in the morning. Some pharmacist told me it can be taken after meal while other advise to take morning before meals to get better effect. Hence, I’m confused. to take LactoGG before meals or after meal.

      Thank you very much

      • evan says:

        Hi Chris,

        I am not aware of any long term negative effects of probiotic use over the long term. I personally have small doses almost every day.

        I think it is wise to cycle a supplement, say take it 2 months on, 1 month on, but you should consult a doctor about that.

        I wish your hubby well,

      Hi I have diabetes 2 and just started taking Culturelle. I also have high B/P which is too, under control. My question Can I take RepHresh Pro B along with Culturelle? This is a Probiotic Feminine health product.

      • evan says:

        Hi Sue,

        You would need to ask your doctor if it’s safe to take those probiotics with high blood pressure.

        Generally speaking, people can take multiple probiotic products together if they want. They just need to be careful to not take too high of a dose and cause side effects.

    12. rob car says:

      I notice on the directions of culturelle, if you are hiv positive, you shouldnt take this product.
      can you tell me why not?

      • evan says:

        Hi Rob,

        In people with extremely extremely compromised immune systems, there is evidence that probiotic supplementation can be harmful. Also, they probably do that for product liability reasons.

        to your health,

    13. Michelle says:

      Hi, may I know that what is the best time to take lacto gg in a day?

      • evan says:

        Hi Michelle,

        I believe the best time to take probiotics first thing in the morning, with a large glass of water.

        The worst time would be along with a meal that has meat in it, because your stomach will be especially acidic.

        take care,

      Hi how about psoriasis, do you think can be reduce or can be cured by LactoGG?

    15. Mena says:

      Hi, can I use culturelle probiotics for candida yeast infection? Is it really powerful?

    16. Mena says:

      Thanks Evan for your reply.
      I got both of these strains already. What’s the dosage do you think to be powerful for intestinal candida overgrowth?

    17. Tam says:

      Hi I’m honesty not sure what’s my issue, I am on probiotics and I do drink a lot of water and consume loads of fiber. I don’t think I’m constipated because I can poop 2-3 times a day. It also isn’t diareah. My problem is that whenever I finish pooping with ease, once I start washing my butt, litttle bita of poop keeps coming out and when I try to go back to release nothing comes out but when I start washing it again it starts coming out again. It also isn’t watery, it’s like tiny bits. I would take hours in the toilet just to clean. I’m so stressed out and have developed a phobia to go to thw toilet now. I’m starting to feel so depressed and when I do consult help, everybody keeps claiming it’s all in my mind. What am I to do? Let them watch me wash my butt or smth? Im a 19 year old going to be 20 male btw.

      • evan says:

        Hi Tam,

        Is there anything you can do that makes it worse? That makes it better?

        I would do less/more of that respectively.

        good luck :)

      Hi Evan,

      Thanks a lot for answering above questions, I’m certainly learning a lot about probiotics.

      I keep reading the term lacto gg, is it the same as Lactobacillus Rhamnosus? or lacto gg is just one kind of the Lactobacillus Rhamnosus?

      Thanks first for your time and attention.

      My 14 year old son has tree and nut allergies. Can ge take Culturelle

    20. Linda says:

      If I broke out with abscess on my stomach its taking long to heal can probiotics can help thanks

      • evan says:

        Hi Linda,

        I would ask your doctor.

        But on this page: – it says:

        People with weakened immune systems get certain abscesses more often.

        So I would do things that strengthen your immune system. There is research showing that probiotics can help certain aspects of your immune system, but I would always check with your doctor first.

        Take care,

      Hi.. can i take lacto gg for my 1yr 2months baby.. she always get high fever n infection.. and 5 times already took antibiotics for pneumonia, otitis media, bronchytis..

    22. Clavis says:


      My 3 yr old Son has milk allergy and sinusitis problem. Starting In Oct 2018, he ate some cakes with milk content 3 times in 1 week, due to 3 classmates’ birthday party. Though teacher tried to scrape off most of the cream on the cake, he still flare up with allergic symptoms. Doctor prescribed antibiotic (Augmentin) after a nose swap test as he had very yellow thick mucus, blocked nose and post nasal drip.

      2nd more serious flare up was in Dec 2018, again doctor prescribed antibiotic (Claripan) … not working, gave Augmentin double dose, still not working. Took nose swap test and realised needed Bactrim.

      In Jan 2019, he went to another preschool fully air conditioned. He has flare up due to the food he ate , though milk content is only a little . He seems to be getting more sensitive to milk content. Doctor prescribed Antibiotic (Augmentin) for 1 course (5ml 2 times a day) and took Low dose (5ml 1 time a day) for the remaining 1 month.

      He seemed getting better… In the last 2 weeks of the course, (March) he was suddenly coughing and sniffling due to some air pollution (very strong burning smell) I started him on LactoGG (1 capsule a day) and next day he gave a slightly mashy poop. He’s usually constipated and had hard poop. His mucus was transparent turned whitish, whitish with light yellow , then whitish and By the time he finished the antibiotic, his cough and runny nose was gone. I remain giving him 1 capsule a day .

      In 1 Apr he flared up again , but the inflammation didn’t come so fast like previous few times. Till today 10 Apr, his mucus remains whitish. I can see improvements to his immunity though there’s still flareups.

      Normally I give him 1 capsule a day. But during flare ups, when he’s taking medication like antihistamines, can I give 2 capsules a day till he’s well and resume to 1 capsule a day? If can, do I give 2 capsules together or must I separate 1 in morning and 1 night?

      • evan says:

        Hi Clavis,

        Thank you for your question.

        I don’t know how probiotics and antihistamines interact. You would have to ask your doctor about that.

        You can experiment with a higher dose on your child if you want, but it may carry some sort of risk. I would personally stick with the recommended dose unless a doctor okay’d it. I think it’s important to stick with the recommended dose because your child is so young.

        To your son’s health,
        Evan Jerkunica

    23. Maria says:

      Hello, I have a 22 month old girl that has been getting recurring ear infections she was placed on different antibiotics for the past 5 months. She has then developed acid reflux symptoms I was told by the pediatrician that it could be caused by all the antibiotics. He placed her on nexium and probiotics. Culturelle kids I tried it and noticed she was very uncomfortable and has diarrhea. Ped prescribed the probiotics to help the diarrhea but it got worse. So I found the cultirelle baby packets for babies from 12 to 24 months I tried it. It seems a little better her stools are still loose more than usual and yellow in color no matter what she it’s they are still yellow. I can feel and hear her stomach gurgling a lot. Is this a normal reaction to the probiotics? Not sure if I should stop or reduce I’m only giving it to her once a day. Should I do every other day?

      • evan says:

        Hi Maria,

        It’s hard to give very specific advice to someone so young and important. First I would ask, what did your doctors recommend for you to do?

        And if they told you to experiment, I would experiment with different dosages, frequency etc. But if they didn’t, I would not experiment.

        Babies are too precious to not follow doctor’s advice.

        To your health,
        Evan Jerkunica

    24. Maria says:

      Thanks for your advice. The dr has not been very helpful he seems to not take my babies symptoms seriously. He recommended the probiotics twice a day I have been doing them once a day because I wanted to see if she would react ok. The probiotics seems to really bother her stomach. During the weekend I did not give her any and she seemed fine except her tummy got a little bloated but no gurgling sounds in her tummy she didn’t grab her stomach in pain before a bowel movement. Which she does when she is in the probiotics she sits down and holds on to her stomach and complains that it hurts. I’m not sure what to do perhaps it time to find a new pediatrician. She had been on probiotics before and she did fine no issues but this time around after all those antibiotics it seems like her tummy is very sensitive.
