Why you need to take the best Probiotic Supplement!

I recently had the privilege of sitting down with one of New Zealand’s most sought after Medical Research Consultants, Corene Humphreys.

I invited Corene to come speak with us about the benefits of Probiotic supplements and how they work, with the end goal of finding What is New Zealand’s Best Probiotic Supplement, that meets all of Corene’s criteria.

View the transcript below. I encourage you to place comments at the bottom of the page also.


We are here today with Corene Humphreys to learn about probiotics.

Corene is a registered naturopath who graduated from the South Pacific College of Natural Therapeutics, here in Auckland, with a Diploma in Naturopathy,  Medical Herbalism and Homoeopathy.  As well as this she received, from the Charles Sturt University, a Bachelor’s degree in Health Science and Complementary Medicine.

For a number of years Corene operated a multi-disciplinary practice, specializing in Functional Medicine.  She also served as a clinical consultant for a number of specialty diagnostic companies which lead her to immigrate to the USA  in 2001.

During her role with the American company Genova Diagnostics, Corene was instrumental in developing a Comprehensive Gastrointestinal Profile, along with other specialty gastrointestinal and metabolic profiles. She also served as an educational resource for physicians, consulting to thousands of practitioners in the US and overseas. Corene has lectured extensively on numerous medical topics throughout the world and authored a chapter in the Textbook of Natural Medicine on the topic of Intestinal Permeability.

When she returned to New Zealand in 2006, she founded a research company which sees her developing natural evidenced based formulations for a number of health conditions. Corene regularly travels abroad attending medical conferences to keep abreast of the latest research in the field of Complementary and Alternative Medicine and has a special interest in probiotics.

Welcome Corene.


Thanks Leanne – it’s great to be here today.


Corene, what made you so interested in the field of probiotics?


My initial training was in the field of medical microbiology where I worked in both private medical laboratories and public hospitals in NZ and England, so I have a good understanding of microbes on a biochemical level. Then when I was in private practice, I predominately specialized in gastro-intestinal health issues and would regularly send samples overseas to specialty laboratories to assess gut microbes –  because labs in NZ don’t test for probiotics.  As a result, I was able to see which probiotics I gave my patients were effective and which ones did not colonize the gut.

Given my combined background of microbiology and Naturopathy, I was invited to be the medical specialist for the Gastroenterology division at Genova Diagnostics. This was a wonderful opportunity and allowed me to help develop novel diagnostic tests to assess GI function and beneficial bacteria in a non-invasive way. In this role, I regularly attended microbial conferences to keep abreast of the latest knowledge and now that I am back in NZ, I still continue to attend probiotic conferences in the US and Europe. For me it is such a fascinating field and it is a real honour to hear first hand from the researchers, the latest developments in the field of probiotics – it is such a rapidly growing industry. It is the information from the researchers along with scientific papers that I use to source evidenced-based probiotic supplements.


So, Corene, can you tell us what a probiotic actually is?


Probiotics, as defined by the Food and Agriculture Organization of the United Nations and the World Health Organisation, are “Live microorganisms which administered in adequate amounts, confer a health benefit on the host”

The key words (to me) in this definition are “live” and “adequate” – a probiotic supplement containing bacteria that are not viable (or alive) at the time of use is not a probiotic.

And, having a probiotic in an adequate amount is also very important.


Do we need to take probiotics on a regular basis or just when our gut flora has been altered as is the case when we take antibiotics?


I believe we should take probiotics on a regular basis. This is because our diet has changed so much over the years. Historically, fermented foods (that contained bacteria) were part of our diet because we didn’t have fridges and we needed to preserve our food. These days’ things like sauerkraut or lactic acid broths are not part of most people’s standard diet.

We actually have 10 times more bacterial cells in our gut than we do tissue cells forming our entire body. To give a sense of numbers, it is estimated that we have approximately 100 trillion bacteria in our gut. For this reason, some researchers consider our gut bacteria an organ in its own right.

Probiotics or beneficial bacteria also perform a number of important roles in the body including immune regulation so it’s important that we do have adequate amounts of beneficial bacteria in our gut.


Can you give us some specific examples of what beneficial bacteria do in the gut?


Sure, probiotics make certain B-group vitamins (for example Vitamins  B2, B12, folic acid and biotin) and vitamin K in the gut. They also produce short chain fatty acids, which provide up to 5-10% of our total body energy requirements. And as I mentioned before, they help regulate our immune system. They do this by stimulating the maturation and balancing of the immune system at birth and then go on to stimulate and prime the immune system throughout life. This enables us to have a correct response to dietary and environmental allergens and also tolerance to our normal flora (i.e. so we can differentiate friend from foe). Priming the immune system allows our body to react quickly to potentially harmful challenges like pathogenic bacteria.

Most people aren’t aware that about 70% of our immune system resides in our digestive tract (known as GALT or Gut Associated Lymphoid Tissue).


What are some of the misconceptions about probiotics?


There are 3 main misconceptions from a consumer stand point and these relate to the quantity of probiotics in a dose, the belief that multiple strain formulations are better, that we need to take probiotics AWAY from food and that all probiotics must be refrigerated.

Let’s start with the first misconception about probiotics – that of quantity.

Some probiotic companies have misleadingly educated the public that “more is better” in terms of the number of colony forming units (CFU) of probiotics in each capsule.  Now many companies are competing to have higher and higher amounts of probiotics in each capsule.

It is a fallacy that more is better.  This can only be determined or proven from researching a particular strain, or a strain combination at a defined dose and assessing the outcome. What science has demonstrated, is that the beneficial effects of a probiotic are dose specific and strain specific.

At this point, it is probably best if I take a step back here and define “What a probiotic strain is”.  Most people have heard the name Lactobacillus and know this organism to be a form of beneficial or ‘friendly’ bacteria. There are in fact a number of different types of Lactobacilli, for example Lactobacillus acidophilus,  Lactobacillus rhamnosus,  Lactobacillus bulgaricus and so on. If we just use the word Lactobacillus, when have identified the genus.  If we say for example Lactobacillus rhamnosus, we have identified the genus and the species (‘rhamnosus’ is the species).  We can also further define a probiotic by identifying the strain which is done with genetic typing using sophisticated methodology (such as pulse field gel electrophoresis). For example, there is more than one type of lactobacillus rhamnosus and when we identify the strain e.g. Lactobacillus rhamnosus GG, we have further characterised the organism.

It may help if I give you the analogy of this using makes and models of cars. If someone said they owned a Toyota (this would be equivalent to the genus), it could be a number of different cars or even a 4WD. They could further define what type of car by sharing the model e.g. Toyota Hilux-Surf (the equivalent of the species of an organism). We now have a far better idea of what type of car this person has, but there are still a number of different types of Toyota Hilux Surf’s which can be further defined by the year and the particular type of model (or in bacterial terms, the strain). If someone said they had a Toyota (genus) Hilux-Surf (species) SSR-G, 1995 (strain), we now know exactly what type of car the person has and if we were to review the manual (or with probiotics, the research papers), we would know exactly what features it has for example, a turbo engine, ABS brakes, runs on diesel etc.

Just as cars are different from one another, so are bacterial strains. We can’t for example say all Toyota’s have 4 wheel steering – that is specific to the type of model, just as the health benefits of a probiotic are specific to the particular strain. We can’t say all Lactobacilli reduce the incidence of respiratory infections because that would depend on what strain we were using. So one pearl is to look for probiotic supplements that cite not just the genus and species of an organism on the label, but also the exact strain.

So getting back to the misconceptions surrounding probiotics, we have also been misleadingly taught “the more the merrier” – that is, multiple strain formulations are better than single or two strain formulas.

Many companies combine a number of probiotics and in super high doses. These types of products are often cheaper to produce (because there are no studies to fund) and sound impressive, but don’t always have the desired beneficial results.

Certain bacteria, for example, may compete with one another, or reduce the efficacy of another strain or even negate the beneficial effects altogether! For example, some strains help stimulate the immune system and in this capacity are great for colds and flu’s, where other strains help tone down exaggerated immune responses, as is the case with rheumatoid arthritis. If these strains are combined in a formula, we don’t know what the overall effect will be on the immune system. We can only determine this if we perform robust clinical trials.

For this reason, it is far better to have a few proven and well studied probiotics, in sufficient quantities, than a whole bunch of probiotics with little research to support their use – either in isolation or in combination with other strains.


That clarifies things a lot – thanks. Now what about when to take a probiotic and whether or not we need to refrigerate probiotics?


When to take a probiotic and whether we should refrigerate is really dependant on three things:
1)    The type of strain we are using
2)    Whether or not we have used any special encapsulation technology
3)    The type of packaging

How about I first share the journey of a probiotic in the gut, as this will help explain these last two misconceptions?


That would be great.


Probiotics undergo quite a mammoth journey to get to the colon – they first have to survive the stomach acid which has a very low pH, (as low as 1.4), then once in the small intestine, the pH radically increases (up to 6.5) and there are also harsh bile acids to content with. All these factors can easily kill the bacteria. Stomach acid is after all Mother Nature’s Antibiotic,  to help protect us from harmful bacteria in our environment.

One way to overcome these challenges,  is to select strains that have demonstrated acid and bile tolerance – this can be assessed in the laboratory, or we can perform human studies to see if the probiotics can be recovered from the stool – that way we know the specific strains can survive the acid and bile AND reach the intestine, still live.

Another way is for companies to use a specialized gel matrix coating on the bacteria themselves or to have special enteric coated capsules which allow the probiotics to get past the stomach and then hydrate in the intestine.

Companies should be able to provide scientific evidence of the organisms’ ability to tolerate stomach and bile acid and share if they have utilized any special encapsulation technology.

If they do have acid and bile resistant strains and/or a protective matrix coating or enteric coated capsule, it really doesn’t matter if the probiotics are taken with or away from food. For this reason it is best to adhere to the instructions on the particular supplement, rather than just assume that all probiotics should ideally be taken away from food.


This is very helpful – now to the last misconception, why do some products say to refrigerate and other probiotics seem to be fine at room temperature?


Probiotics as we have already established, are live microorganisms.  Before there were specialized drying techniques, encapsulation technology and novel packing systems, it was best to keep the bacteria cold to reduce moisture and degradation. Think of having a bowl of fruit on the table in the sun vs. having a bowel of fruit in the fridge – it is the refrigerated bowl that will last a lot longer because there is less moisture and heat.

Nowadays, we have far more sophisticated methodologies and laboratory procedures to protect probiotics during the manufacturing process. For example, freeze drying the probiotic helps preserve them and having temperature and humidity controlled manufacturing rooms helps control the moisture content – it is exposure to moisture and oxygen that decreases the viability of probiotic bacteria.

There are also specialized packaging systems that can protect the probiotics from exposure to oxygen and moisture once they have been encapsulated.

Manufacturers should be testing their probiotic as soon as it has been cultured, at the time of packaging and throughout the product’s shelf life to ensure there are viable cells and they can meet the label CFU (colony forming unit) claim.


Why would someone want to take a probiotic and what kind of benefits could someone expect from taking one?


You could (as mentioned earlier) take a probiotic daily to ensure a regular supply of beneficial bacteria in the gut. Taking a probiotic for a short time doesn’t mean we continue to harbour that organism in our gut once we have stopped ingesting. Depending on the particular strain, it may not be recovered from the stool a few weeks after or even a few days after we stop taking the supplement. What we do know, is that regular ingestion (of a viable probiotic) ensures we do have an ongoing supply of friendly bacteria.

We can also take probiotics for specific conditions, for example health care professionals may recommend probiotics for digestive disorders like diarrhoea, constipation, lactose intolerance, gas, irritable bowel syndrome or inflammatory bowel disease or even Helicobacter pylori infection. Other times when probiotics are recommended are with yeast infections, following antibiotic therapy or for immune support.

As the research continues, I expect we will see a lot more probiotic supplements that are condition specific – for example probiotics for high cholesterol, probiotics for diabetes, probiotics for respiratory infections and so on.


What should people look out for when choosing a probiotic?


As I mentioned, make sure the probiotic has strain specific organisms and that it is a formula with research to support its effectiveness. If it is a combination formula, then ideally, it should have documentation or studies that show the strains are still effective when taken together.

The dose should be expressed in CFU’s and the manufacturers should perform stability testing on each batch throughout the product’s shelf life to ensure the probiotics remain viable until or even beyond the expiration date.

Probiotics should also be packaged in such a way, so as to protect them from exposure to light, oxygen and moisture –  as all these factors can affect the viability of the bacteria.


Are there probiotic formulas on the market that meet all these requirements?


A new formula that has recently been launched on the NZ market is a product called Clinicians™ MultiFlora. This probiotic formula does meet all the criteria that I mentioned.

It contains two strains – Lactobacillus rhamnosus GG and Bifidobacterium animalis BB12. These are two of the most studied and scientifically researched strains in the world1 and when combined, these strains have demonstrated synergistic effects – that is the addition of one (BB12) enhances the presence of the other (LGG).2

Research has shown that Lactobacillus rhamnosus GG and Bifidobacterium animalis BB12 can be used for a number of gastrointestinal conditions including diarrhoea, Constipation3 and Irritable Bowel Syndrome.4


Is CliniciansTM MultiFlora good for a specific type of diarrhoea?


Studies show that the strains in Clinicians MultiFlora are effective for many types of diarrhoea including infectious diarrhoea, traveller’s diarrhoea, antibiotic-associated diarrhoea and diarrhoea of viral aetiology (e.g. rotavirus). It is also is considered a beneficial adjunct to conventional triple therapy for the eradication of Helicobacter  pylori.5


That’s impressive! Can you use MultiFlora for any other conditions or diseases?


Yes, other applications that have been studied include atopic eczema in children and infants. It helps prevent eczema and can also reduce the severity of an outbreak.6 And, CliniciansTM MultiFlora is safe to take during pregnancy to help prevent early atopic disease in newborn babies especially when there is a family history of eczema.7

It is also an ideal supplement to support immune function and can help reduce the incidence of respiratory infections in children.8 Studies have shown that B. animalis BB12 can help improve overall immune function in both the young and the elderly.9

If you suffer from pollen allergies it is a good probiotic to consider as there is research to show that LGG can increase our body’s immune response (through increased IgA levels) to help protect against birch pollen allergies.10

Research also indicates that CliniciansTM MultiFlora may help protect against colon cancer by improving the composition of the bowel flora and favorably altering cancer biomarkers in the gut.11

Given its many indications and demonstrated protective effect on the gut, it can be used as a “condition specific probiotic” and a probiotic for general well being – it’s the one I take every day.


How about the stability of this product and the packaging?


Clinicians TM MultiFlora has research to show it can survive stomach and bile acids.  As well as this, it also has a specialized polysaccharide encapsulation technology to ensure the strains reach the intestine intact. Vegetable capsules are used to further reduce the moisture content which also makes this product suitable for vegans and vegetarians.

With regard to packaging, CliniciansTM MultiFlora is packaged in special Alu/Alu blister packs that enable the bacteria to remain viable in room temperature environments. As well as this, stability studies are performed over the product’s shelf life to assess the CFU’s and moisture content. Each MultiFlora capsule is individually packaged with easy tear-off perforations so you can conveniently take with you when travelling; without the need for refrigeration.


Are the probiotics in Clinicians MultiFlora safe for everyone to take?


Both strains have demonstrated safety in general.  There are studies to show they are safe for all age groups, from infants as young as one month old to children, right through to adulthood and the elderly.12-15 Women can also take it during pregnancy and while breast feeding.

Probiotics are generally considered safe and well tolerated however, there are certain situations that require caution.

You should consult your physician before using probiotics if you have recently had radiation therapy, oral or gastrointestinal surgery (particularly short bowel loop) or if you are immunosuppressed (such as those with HIV). Under such circumstances, there is increased susceptibility of bacterial translocation across the gut wall which can increase the risk of infections.16


What dose would you advise to take for general well being and how much MultiFlora would you take for a specific health complaint?


At the time of manufacture, there are over 7 billion CFU’s in Clinicians MultiFlora or greater than 3.5 billion CFU’s of each strain per capsule.

For adults, if they are taking this for general well-being, the dose is one capsule once or twice a day with food. The dose in clinical trails varies between 5-40 billion CFU’s/day and is dependant on the particular health condition.

For example, to increase immunity, doses have varied between 4-40 billion CFU’s per day. For skin conditions, good results have been demonstrated at 20 billion CFU’s per day (which is 3 capsules). 20 billion CFU’s is also a suitable dose following antibiotic therapy. When used alongside triple treatment medication for H. pylori eradication, studies have shown that 12 billion CFU’s per day reduces the antibiotic side effects such as bloating and diarrhoea and improves overall tolerance to the medication.

For children 3 years and over, the recommended dose is ½ to one capsule a day with food – the 2 piece hard-shell capsules can easily be twisted opened and the contents mixed with milk or water (not fruit juice – as you want something with a neutral pH).  Make sure the liquid is not warmed.

The dose for infants 1 month to 3 years is ½ a capsule daily,  mixed in with milk or water.


Corene, this has been invaluable, thanks SO much for your time today.

    This is really interesting. I know that Corene is an authority on microrganisms and it’s very interesting to read this article.
    I lamented the fact that the old Multiflora formula(also 6-MF in Vitalize range) was changed as it was one I used all the time for myself and clients. But with this new information, instead of just being told “it’s better”, I feel a lot more confident recommending it again. Thanks for the quality information. Nice work Leanne!

  2. Jodie Bonfrer says:

    Very very good article I wish doctors would promote it to patients when on antybiotics I use probiotics all the time and tell every body to do the same.
    If they do I don’t know tho.
    I alway’s say you can take a horse to water but you can’t make them drink it
    Thanks for putting it on here.
    Love Jodie

  3. Lilac Guthrie says:

    This has cleared up the confusion in my mind about the bacteria strains in probiotic supplements. I have been using Inner Health Plus for the last five months. While there hasn’t been noticeable improvement in my bowel conditions, the last few weeks I have been experiencing a flare. I would very much like to try Clinician’s Multiflora but am hesitant because it may contain traces of milk products. I am also on immuno-suppressant MMF and prednesone. I would like to know if I can take Clinician’s Multiflora, or if I should take probiotics at all.

    • Corene Humphreys says:

      Dear Lilac,

      The starter material used to culture the LGG and BB12 organisms is skim milk – most probiotics are either cultured from dairy or soy and personally I think GMO soy is not a good medium. Starter mediums are also known as substrates and generally, there is very little if any of the initial substance left in the finished product. Because the company knows it is the starter material in the product, they have declared it. Natural Health Laboratories have cited in their educational material the statement below to help address this question.

      Clinicians MultiFlora is cultured on a skim milk base and may contain traces of lactose in the finished product. Studies on Bifidobacterium animalis BB-12 indicate that this strain exhibits lactase activity and can help assist with lactose digestion.1 This product should therefore be suitable for lactose intolerant individuals. Individuals with severe IgE mediated dairy allergies should avoid taking Clinicians MultiFlora or consult their health professional first.

      of commercial cultures in fluid milk applications. J Dair Sci. Jun 1996;79(6):943-955.

      On a personal note I am lactose intolerant and use this product without any untoward effects.

      Kind regards,

    Thanks for the info, Leanne.

  5. Yvonne says:

    You say that probiotics come in capsules in order to withstand the bile etc in the digestive system. Infant probiotics comes in powder form, so is it at all beneficial given that it does not have a protective coating?

    • Corene Humphreys says:

      Dear Yvonne,

      If you are using a probiotic powder for infants, then you should ideally purchase one that contains a specialized gel matrix that is part of the probiotics – ie it is added to the strains during the manufacturing process. The Chr. Hansen probiotics LGG and BB12 use a patented polysaccharide matrix on their strains so they are protected from stomach and bile acids. You can therefore open these capsules and add to water or milk. Emptying the capsules into either milk or water also acts as a buffer due to the neutral pH of these liquids.

      Kind regards,

  6. Leen Auperle says:

    Hi Leanne,
    Thank you for putting such an interesting interview on your website.
    There is always more to learn and I may come in to buy that product when the one I am using at present is finished.
    Keep up the good work!

  7. barb says:

    I have been drinking kefir for quite sometime.. as this is a totally natural product..how does it compare in Corene’s studies…??

    • Corene Humphreys says:

      Dear Barb,

      Kefir is a fermented dairy product that has been used to aid digestion, lactose intolerance and reduce high cholesterol. The active constituents are the polysaccharide kefiran and beta-galactosidase. As part of the fermentation process, it can contain a number bacterial species including L. lactis, L. casei, L. helveticus and Streptococcus thermophilus. Saccharomyces cerevisiae and Candida species can also be found in Kefir. Many of these strains can survive stomach and bile acids and reach the intestine in tact. It is generally well tolerated but because it does contain living bacterial and yeast organisms, caution is advised with immunocompromised patients as there is a theoretical risk of bacteraemia and fungaemia.
      There is some research to suggest that the kefiran polysaccharide may help increase immune function directly in the intestine as systemically. To date, however, there is insufficient scientific evidence for its effectiveness and peer reviewed studies on cholesterol reduction have been conflicting and predominately show little or no beneficial effect for this condition.1,2,3

  8. Rachael says:

    Great article. My 5 year old son has been on a probiotic for several years, initially because of silent reflux (and being on a reflux medication which makes the stomach acid really low – not good for the gut bacteria) and also because of food allergies. He no longer has the reflux and has no food allergies as far as I’m aware, but I still give the probiotic to him daily as I have always known that probiotics are extremely good for your immune system. However after reading this article I will probably be changing probiotics as the one he currently takes has neither of the two strains mentioned in this article.
    Leanne I do have one question though – is this the ONLY probiotic that Corene recommended?

    • Corene Humphreys says:

      Dear Rachael,

      Relative to the interview, this was the only probiotic I mentioned for colonic health. For vaginal health and prevention of bacterial vaginosis and yeast vaginitis, the strains L. rhamnosus GR-1 and L. fermentum RC-14 have Level 1 evidence for “the maintenance and restoration of vaginal flora”. This product is called FloraRestore and Leanne also stocks this product.
      As I mentioned in the interview, a probiotic is only considered one if it contains live organisms. There is a product called Del-Immune V that I discovered when living in the US that is a fantastic immune modulator (and is also quick acting). It is not actually a probiotic because the strains have been lysed in order to liberate their immune modulating properties. It is great for preventing and treating colds and flu’s and for priming the immune system to protect against viruses and infections. It is also good for overly active immune systems such as those with rheumatoid arthritis. It was actually developed for protection against the cold war and has a lot of research to support its efficacy. If you are interested in learning more about this product, you can visit the US website: http://www.del-immune.com
      This product was one of my “must haves” when I returned to NZ, so I worked collaboratively with Natural Health Laboratories and Pure Research Products in the US to import.

      Kind regards,

        hi my daughter is breastfeeding her 10 day old son, she has many vaginal stitches interior and exterior that have now become infected, yesterday the doctor gav her a script for antibiotics, she also has vaginal thrush, its all very painful and stressful.
        my question is this which probiotic would you recommend ie: one for the gut, the vag thrush…..immune boost ? your article was very very interesting thankyou.floral restore – del immune ? HELP she is also breastfeeding, my concern is that the little son will end with his intestinal flora stripped and compromise his health and the thrush getting hold too and for my daughter …the antiobiotics compromising her immune system and the trush taking hold as is is already present even before the medication.

  9. Rachael says:

    Thanks for this information Corene. I will definately have a look at that link you mentioned.
    I am still not sure if there is another probiotic that you recommend (not just another product good for the immune system). Is there another probiotic (ideally one that can be bought in NZ – if not then a probiotic available elsewhere) that you recommend for maintaining good gut health as well as being good for the immune system (and please mention if it is also good for other specific conditions).
    Do you know of another product (ideally available in NZ) that has the same strains as those in the Clinicians MultiFlora you talked about?
    Many thanks

    Hi Corene,

    For the past 4 years I have been suffering from “Lichen Planus” on my lips and a lip biopsy by a dermatologist here in Melbourne has confirmed the same.

    Lichen Planus being an auto-immune disease skin condition (similar to eczema) was wondering if there is any research about Probiotic supplements helping cure or atleast less the condition. Since there is no knowledge on the cause and a cure, I suspect it has something to do with an unhealthy colon.

    The most advertised Probitic supplement here is Australia is called Inner Health Plus which contains Lactobacillus Acidophilus (NCFM) organisms (12.5 Billion); Bifidobacterium Lactis organisms (12.5 Billion) & Colostrum Powder – Bovine (67 mg).

    Thanks in advance.

    The human body has a set of microorganisms that takes care of the body. It guards the body from harmful microorganisms as well as help in the digestion of food. Due to the present environmental conditions as well as antiobiotic medicines disturbs the biotic community in the body thus making the body prone to diseases. This probiotics will replenish the body’s biotic community.

    I hope you still check this blog 🙂 I normally get a yeast infection right around my periods. My family MD yesterday said to take a probiotic it’s called:
    Ultra Flora Plus DF Capsules
    50/50 blend 15 billion live organisms
    Lactobacillus acidophilus NCFM
    Bifiobacterium lactis Bi-07
    Only thing I’m alleric to is Suflar
    I took it last night after dinner (I open the capsule) and put on my yorgurt. I don’t swallow pills very well. Anyhow I woke up this morning with a tummy ache (liitle one) and with in 2 hours I went to the bathroom two. I called the dr office they said they never hear of this. I was wondering if this is my body getting use to the probiotic and should i continue taking it or stop. I’m going to take 1/2 for the next couple days and if my tummy is still really upset I might stop taking it. I also heard that the the way I’m feeling might be the good bactiria doing it’s job and I should feel better in a couple days.

      It does upset me when doctors start “getting into” natural health and start recommending natural health supplements but aren’t aware of their action and the possible effects that can happen when you take them.

      Yes this is a “normal” reaction. It shows of “die off” which is what happens when you take a probiotic and you have a candida overgrowth. When the probiotic touches the yeast cell wall, it disintegrates and dies. Not only can this make you feel unwell and kind of hung over, it can upset your bowel – as your body tries to purge it out.

      I hope this clarifies this for you.

    Thanks for a really interesting interview with Corene. I have read that probiotics can help with symptoms of coeliacs disease. Any comments on that?

    • leannejames says:

      Hi Thanks for your comment. Yes we were very honored to have Corene take time out to explain all of this to us.

      We would Always recommend a probiotic to anyone who had any kind of bowel problem, let alone in coeliacs disease. There has also been some interesting information with regard to colostrum and coeliacs disease, where they have seen villi start to heal and “re grow”. If you phone my shop 09 443 2584, we have some information about this specifically that we would be happy to send out to you. It comes in the form of a newspaper type brochure, specifically about the Radiance Colostrum, which is a high immunoglobulin (IgG) bovine colostrum from healthy, pasture fed, pesticide, hormone and antibiotic free cows. It has been carefully manufactured to ensure maximum absorption and biological activity, providing a minimum of 15-20% IgG content for optimum effectiveness.

      I hope this information helps you.

    What is your, or Corene’s opinion of Yakult ?

    I am primarily interested in probiotics as a treatment for constipation. Which one is best for this ?

    • leannejames says:

      Hi I cannot speak for Corene, but we (at Ideal Health and Healthyonline) like the Ethical Nutrients Inner Health Plus. This contains medical strains of probiotics, that are acid and bile resistant. As well as this, My self (as someone who suffers with constipation) I also take a daily dosage of the herb Cascara sagrada. This increases peristalsis, the normal squeezing and contraction of the bowel. It also makes the bowel motion more watery. This is because cascara increases bile production which causes the increase in peristalsis and attracts fluid to the bowel motion. Here is a link to the cascara

    Hi, my mother is extremely ill with rheumatoid arthritis/fibromyalgia. She also has the condition where her right food is now permanently curved to the right. She has a very low immune system and is often getting infections. Just lately she has had two bouts of cellulitis. I asked her if she was taking any immune boosting vitamins, but she is too scared to try anything incase it interferes with her copious amounts of medications that she is on. Would an inner health probiotic be good for her, or could it interfere? Thank you

    • leannejames says:

      Thanks for your comment. A probiotic will definitely help with better immunity, as 70% of our immune system is situated in our intestinal wall. Because your mother in extremely ill, I would suggest the Inner Health Plus POWDER, not the capsules. This is because with the powder, you would be able to start her off with just a very small amount of powder and gradually increase this. The “rule” with people like your mum who take a lot of medication is to make sure she does not take the probiotic at exactly the same time as her pharmacy medication. Most people take theirs just before bed. Here is a link to the powder

    Dear Corene,
    Excellent article
    I have Rhuematoid arthritis and am wondering which would be best for me to take
    Also 5mth old granddaughter has bad ezcema and wonder what/which you would recommend for her.

    Hi I currently get a probiotic from the U.S. from New Earth but would like to get one from New Zealand if possible for my children who have multiple food allergies. Could you reccommend one that doesn’t have dairy,egg or nut traces? My children are 3 and 6yrs old. Thanks

  21. Rachel Kirkland says:

    Hi there,
    My son is 16 months old with a range of food allergies.
    I am now expecting my 2nd child and I have been told by our Allergy Specialist to take a probiotic while pregnant.
    What is the best probiotic/strains (available in NZ) for this purpose? I will take it through pregnancy and breast feeding.

  22. Danae Johnston says:

    Hi There,
    thanks for your info, I find the variety on the market very overwhelming! Just to confirm a few things;
    I have a 3 year old and a 18 month old, both suffer with mild eczema, no other allergies. What would be the best probiotic for them? Also wanting to give to my 18 month old who has needed Antibiotics for ear infection lately. Can you give probiotic too often or is it good every day? Are any of the ones you recommend taken in a chew or gummy form for kids? or just powders/liquids?

    Also im pregnant and have been reading your info above and Q&As, im assuming the clinicans one could be beneficial for me, and may reduce chances of eczema for next baby?

    Kind Regards,

  23. Danae Johnston says:

    Does this offer the benefits a probiotic offers as-well? I may end up getting the clinicians one for myself as capsules are just easier, but if this one is actually just better for me/kids I would just grab this one you recommend above. thanks.

    • leannejames says:

      Hi The Multiflora offers the health benefits of a probiotic, where the strain and strength of the probiotic in Eczema shield has been well researched and one of these areas of research is in it use with those who have eczema and also for pregnant women, who want to help to prevent the incidence of this in their baby. But i agree that capsules are so much more convenient. Thanks

  24. Danae Johnston says:

    Sorry to be a bother- another question around a probiotic for myself.. what is the difference between the clinicians one and the eczema shield?

    • leannejames says:

      Hi The Eczema shield contains 20 Billion CFU (Colony forming units) of Lactobacillus Rhamnosus in each 4 gram dose and is a powder. Each 1 capsule of the Multiflora contains 3.5 billion CFU of Lactobacillus Rhamnosus and 3.5 billion CFU of Bifidobacterium Animalis. So the Eczema shield contains over 5 times the amount of Lactobacillus Rhamnosus per serve and the Multiflora capsule also contains a 2nd probiotic strain, as well as the Lactobacillus Rhamnosus. So the Eczema shield is marketed for those with eczema and the Multiflora is marketed for Immunity, intestines and bowel. Thanks
