Advanced Probiotic Formula For Immune and Digestive Systems Support: Approved for GAPS and recommended by Dr Natasha Campbell-McBride (Author of Gut & Psychology Syndrome)

Bio-kult have re-branded with an exciting new look! Take a peek at the new product labels.

We have taken a big hit with the increased currency exchange rates and high Duties & Taxes required to import Bio-Kult into Australia. On top of this we have incurred a price increase from the manufacturer.  Sadly this is unavoidable.

 The healthy body naturally hosts trillions of beneficial bacteria. Amongst other things, they help to support and maintain a strong immune system and a healthy digestive system. Today’s lifestyle of stress and poor nutrition can compromise these essential functions. The complete formula in Bio-Kult helps balance and maintain these natural systems against pathogenic and opportunistic organisms.

It is of fundamental importance that we have an adequate level of these probiotic bacteria in our bodies at all times. With fourteen strains of beneficial bacteria at a concentration of 10 billion per gram, Bio-Kult is one of the most powerful probiotic supplements available.

There are 14 strains of beneficial microorganisms within Bio-Kult:bio-kult-white-back.jpg

1. Lactobacillus acidophilus
2. Lactobacillus delbrueckii ssp. bulgaricus
3. Lactococcus lactis ssp. lactis
4. Lactobacillus casei
5. Lactobacillus helveticus
6. Lactobacillus plantarum
7. Lactobacillus rhamnosus
8. Lactobacillus salivarius ssp. salivarius
9. Bifidobacterium breve
10. Bifidobacterium bifidum
11 Bifidobacterium infantis
12. Bifidobacterium longum
13. Bacillus subtilis
14. Streptococcus thermophilus

Gut conditions

Probiotics represent a nutritional live microbial supplement that positively affects the host by enhancing the microbial balance. They work in a number of ways including: competitive exclusion, production of bacteriocins and lowering of gut pH. Although all probiotics’ mechanisms of action are not yet fully understood, it is known that they also have an effect on immune responses in the gut, which reduces inflammation. The use of probiotics has been suggested for the prevention and treatment of gut health problems, including acute infectious diarrhoea, antibiotic-associated diarrhoea and inflammatory bowel disease.

Common inquiries about Bio-Kult

Bio-Kult contains probiotic strains that have been shown to produce lactase, the enzyme needed to break down lactose, which is usually lacking in people intolerant to lactose. Bio-Kult contains traces of milk products at a level which would not affect lactose intolerance sufferers.

Manufactuers Comments: All our Bio-Kult products are manufactured to an extremely high standard (cGMP accredited) in our purpose built facility in Somerset, enabling us to stay in complete control of our quality standards.  Bio-Kult probiotics are manufactured using the latest techniques.  The beneficial bacteria themselves are encapsulated (with a protective coating) during a freeze drying process (lyophilisation).  This process protects the bacteria while on the shelf and from the harsh acidic environment of the stomach (shown in vitro to survive pH2 for 2 hours).  The Bio-Kult blister pack offers further protection against moisture and extremes of temperature. No refrigeration is required due to this high protection.   An external laboratory undertakes rigorous stability testing on our Bio-Kult probiotics so unlike some other companies, we are able to guarantee stability and count until the end of the two year shelf life when kept at room temperature.  Whilst the manufacturer advises that Bio-Kult does not require refrigeration, some states in Australia will be exposed to higher temperatures compared to those overseas so if the customers expect to store Bio-Kult for longer periods of time beyond 3 months with temperatures rising above standard room temperature or above 30 degrees, we encourage you store Bio-Kult in cool dry place or in the refrigerator.

The manufacturer confirms that Bio-Kult is nut, egg and gluten/wheat free.

Bio-Kult is suitable for:

Gluten free, Casein free, Lactose free, Yeast free and Salt free diets.

Protexin are committed to listening to their customers needs and continuous quality improvement:

  • Bio-Kult no longer contains maltodextrin.
  • Bio-Kult is a non-GMO product:  The bacteria strains used in Bio-Kult are not genetically modified and our supplier confirms that the soya used in the fermentation process of Bio-Kult probiotics is non-GMO.   We use a certified non-GMO cellulose as a bulking agent and our capsules are all vegetable based made of certified non-GMO hydroxypropylmethyl cellulose and approved by the Vegetarian Society. 

Acid Stability of Probiotic Microorganisms in Bio-Kult

In Vitro unbuffered growth at pH 2.0 for 2 hours contact time

Individual pure culture samples of probiotic microorganisms contained in Protexin human health products were tested for stability under acidic conditions to mimic the extreme fasting pH of the human stomach.

In order to produce beneficial effects within the gastrointestinal (GI) tract, probiotic microorganisms must have the capacity to survive and metabolise in the gut. They must therefore be resistant to GIT levels of acid.

Probiotic formulations also need to contain large numbers of viable organisms (highly concentrated) which, on ingestion, survive the rigorous onslaught of the mammalian upper gut in order to deliver their bacterial content to the small intestine. One of the primary barriers to the passage of bacteria is the acidity of the stomach. The pH of the stomach varies throughout the day under the influence of the buffering action which food or liquid may have on the stomach. However, the fasting pH of the human gut is around pH 3.0.

The amount of time for food to pass through the stomach also varies greatly from a few minutes to an hour or more. The food itself will have some neutralising effect on the pH of the stomach and hence a pH of 3.0 is probably the lowest to which the bacteria will be subjected. In addition the food may also have a physically protective role to play.

The conditions of our laboratory tests will therefore probably be the most vigorous conditions to which the bacteria will be subjected i.e., a pH 2.0 for 2 hours and the results obtained need to be analysed accordingly. It should also be noted that the laboratory conditions (in vitro tests) designed for these tests, whilst attempting to mimic the conditions within the stomach are, in fact, only a simplistic view of what is, in fact, a very complex situation.


When held at a pH 2.0 for a 2 hour period there is no significant loss in viability / concentration of any of the bacterial strains. The contact time is extreme - a two hour contact time period without any buffering effect of e.g. food or water, before plating out.

Total viable bacterial counts do not reduce in viability/concentration after contact with acid of pH 2.0 for 2 hours. This means that a high concentration of the probiotic  microorganisms within Bio-Kult survive, which could reach the small intestine and establish themselves as part of the normal microflora.  Laboratory tests are not necessarily a reflection of in vivo conditions although the experiments were designed to mimic the situation as closely as possible.

I find it indeed interesting reading the many great reviews about Bio-Kult. Gut Dysfunction varies greatly from person to person, those who have amazing results with Bio-Kult although unwell, are not seriously unwell and I am glad of this. Myself, I am taking 1.0ml of Kraut brine and the histamine reaction to my body was nothing more than a violent assault. Trying to navigate and repair an unhealthy gut has been a 15+ year journey for me with experts advising me along the way, which have all resulted in nil resolve. GAPS, may offer some help, so I am now in week 3 and still on Stage 1. Adding one egg yoke was extremely painful. Taking one Bio-Kult capsule kept me in so much pain during the night that my sleep was negligible. The histamine reaction was severe, burning legs, boiling body extreme fog and extremely itch skin gas and bloating at severe levels. So I am now at week 3, back to 1.0ml of Kraut brine per day only and will hold off on Bio-Kult for the time being. Glad so many are having so much relief.

I've been using Bio-Kult ever since starting the GAPS diet several years ago to help control severe gut problems. Since then I've taken this amazing probiotic on a regular basis. I can't live without it!.

Our daughters have Autism and we’ve been using this for over 5 years or so it’s fantastic for correcting gut issues and assists in the body’s overall immune response as our daughters Vasculitis is kept in check too.

My husband, adult son & myself have found this probiotic to be very effective. It is user friendly as it doesn't require refrigeration..

Written by JUDITH A SMITH on 13th Jun 2019

I have tried several probiotic offerings over a few years but they were limited in what they could do for gut health [only one or two strains]. Bio-Kult is expensive for me {a pensioner] but its multi-strain formula seems to be doing the trick for me. The only criticism I have is of the foil sealing over my latest Bio-Kult capsules which is extremely brittle and quite difficult to manage when trying to remove the capsules.

Great product, wouldn’t buy any other Probiotic.

Bio-Kult and the GAPS Diet has destroyed Dientamoeba fragilis
Written by Anthony on 18th Jul 2012

My son took Bio-Kult at therapeutic amounts as suggested by the GAPS supplementation protocol guidelines for 12 months and this coupled with the GAPS Diet completely removed it from his system. Absolutely no antibiotics required.
