Our live active cultures

Live active cultures refer to the living microorganisms (microbes) usually found in probiotics or probiotic rich foods (such as yoghurt). Often used instead of ‘probiotics’ live active cultures all have different impacts on the body which is why all our products contain various strains.

There are 15 families of microbes in all of our Bio-Live products to increase the diversity of good bacteria in the gut. Most of them support the gastrointestinal tract and the immune system, reduce inflammation, help the body to fight off pathogens and restore balance.

You can find out more about these microbes and all of the herbs and minerals in Bio-Live in our microbzpedia. You can also find out how we use these live active cultures in our unique formula and how we brew our Bio-Live range. 

These 15 families of live active cultures are:

Bacillus subtilis

Supports digestion, enzyme production and helps to maintain a healthy gut. Bacillus subtilis is a robust strain of microbe that is able to balance the gut. It does this by forming endospores which are long lasting protein envelopes that protect it from heat, light, and other stressors. One study reports that it is so vigorous it could survive in space for up to six years when protected from UV rays.

Bifidobacterium bifidum

Research shows that Bifidobacterium bifidum has had favourable results in treating the following conditions: irritable bowel syndrome (IBS), restoration of intestinal bacteria after chemotherapy, constipation, lung infections, ulcerative colitis, certain kinds of diarrhoea, and necrotising enterocolitis – which is a type of infection in the intestinal lining caused by harmful bacteria.

Bifidobacterium breve

Bifidobacterium breve is a beneficial bacterium that can be found in human breast milk and the gastrointestinal tracts of infant and adult humans. Administration of B. breve to preterm infants triggers an anti-inflammatory response that may be of benefit in attenuating allergic reactions.

Bifidobacterium infantis

Taking Bifidobacterium infantis has been shown to reduce symptoms of irritable bowel syndrome, gas and bloating by articles published in Alimentary Pharmacology & Therapeutics. It has also been known to lower levels of inflammation in patients with ulcerative colitis, chronic fatigue syndrome, and psoriasis.

Bifidobacterium longum

Bifidobacterium longum is a microbe with a long list of health benefits, especially for the colon. It is commonly found in adults and children in the gastrointestinal tract and the female vagina.

Lactobacillus acidophilus

Lactobacillus acidophilus occurs naturally within the body. Not only does it promote digestive tract and immune system health, it also helps in the production of lactase potentially benefiting those who are lactose intolerant. Research suggests lactobacillus acidophilus may provide some benefit for cardiovascular health by reducing cholesterol.

Lactobacillus acidophilus produces vitamin K, lactase, acidolphilin, acidolin, bacteriocin, and lactocin and therefore helps to maintain a healthy balance of microbes in the gut. It helps the body break down lactose into simple sugars and modulates immune system function. Some research even suggests it may provide some help with urinary tract infections, irritable bowel syndrome, and bacteria deficiencies caused by antibiotics.

Lactobacillus bulgaricus

Lactobacillus bulgaricus works well in acidic environments and helps to maintain a low pH in the stomach so that unhealthy bacteria cannot colonize. It works to populate and colonize itself along the lumen walls of the intestines. This microbe is self-regulating, meaning it grows more when it is needed and diminishes when it is not.

Studies show that lactobacillus bulgaricus and other bacteria are beneficial to the microflora within our gut. They serve to out-colonize pathogenic bacteria, as well as creating an environment in which many bad bacteria cannot survive.

Lactobacillus casei

Lactobacillus casei is a superstar of the probiotic world. It is commonly used to make fermented foods like yogurt and cheese and is naturally found in raw cow’s milk and colostrum. Studies from people who have taken lactobacillus casei show improvements in immunity, allergies, cholesterol levels and digestion.

Lactobacillus fermentum

Lactobacillus fermentum possesses multiple probiotic properties, but it has been shown to be most effective at restoring and maintaining a healthy balance of microflora in the female urogenital system. In this capacity, it has been shown to significantly restore the ratio of healthy to unhealthy microbes over a period of weeks.

Of all the Lactobacillus species, lactobacillus fermentum has been shown to have the greatest cholesterol lowering activity. Additional studies are being done to understand the mechanism of action behind its cholesterol lowering properties, but lactobacillus fermentum is already being used for this purpose in some parts of the world with great success.

Lactobacillus plantarum

Lactobacillus plantarum produces its own antibiotics that target bad bacteria. It fiercely attacks pathogenic microbes in our bodies helping positive microbes to grow stronger. It also supports the gastrointestinal system to be more resistant to future pathogens and improves digestion and immunity. This probiotic also makes lysine, an essential amino acid.

Lactobacillus rhamnosus

Research suggests taking Rhamnosus might counteract weight gain and diabetes, and there’s a lot of research examining the benefits as a treatment for gastrointestinal issues like irritable bowel syndrome.

Lactococcus lactis

Lactococcus lactis is a lactic acid producing microbe used extensively in the production of butter, milk, cheese, pickled vegetables and other fermented products. It can hinder pathogenic bacteria and combat disease. Thought of as a hopeful future for cancer therapy.

Saccharomyces boulardii

Saccharomyces boulardii is used for treating and preventing diarrhea, including infectious types such as rotaviral diarrhea in children, diarrhea caused by gastrointestinal (GI) take-over by “bad” bacteria in adults, traveler’s diarrhea and diarrhea caused by the use of antibiotics.

Saccharomyces boulardii is also used for general digestion problems, irritable bowel syndrome (IBS), inflammatory bowel syndrome (IBD, Crohn’s disease, ulcerative colitis) and Lyme disease,


Saccharomyces cerevisiae

Saccharomyces cerevisiae is a nutritional yeast that eats sugars. It is a source of protein and vitamins, particularly B-complex vitamins. It contains folates, thiamine, riboflavin, niacin, selenium and zinc, making it a superfood!

Streptococcus thermophilus

Streptococcus thermophilus is a powerful probiotic strain that has well researched health benefits. This probiotic is often found in the colon and has many digestive and immunity health benefits.

Streptococcus thermophilus is used for culturing cheese as well as yogurt. This probiotic strain also produces lactase, which helps people digest milk more efficiently. Lastly, it produces antibiotic chemicals to prevent infections like pneumonia and can help prevent ulcers.
