Probiotics and Prebiotics

Probiotics are beneficial bacteria, supporting good health and vitality, primarily by improving the balance of flora in the digestive system and impacting on a wide range of interlinked systems. Prebiotics are the non-digestible food ingredients that help [fuel] the development of this bacteria.

Benefits includes improved digestion, immunity system function and more recently emotional, skin and dental conditions.

Why PERKii? Because we make great, better.

Simply we take great probiotics and make them better.

Many products use strains that have shown questionable survival rates, dying in the harsh acid environment of the stomach or in some cases, many ‘cultured’ drinks don’t accurately outline any details of the strain or number of probiotics in them e.g. kombuchas and kefirs.

We’ve solved that by working with the University of Queensland to create a world-first technology with natural ingredients.


We use PROGEL™ to coat our probiotics, effectively armour-plating them against the stomach acids while also providing a form of prebiotics in their organic seaweed-derived covering. Activated at a microscopic level, this means we can make our probiotics undetectable to taste and ensure more living probiotics making it to the gut where they do their work.

Quality & Quantity

While all probiotics are considered safe and friendly by definition, not all probiotics possess health research and benefits to be considered therapeutic. Nor do many drinks carry enough (probiotics) in them to classify as a significant dose.

That’s another area where PERKii differs.

We dose every bottle with 1 billion CFU of a Lactobacillus casei strain, LC431®. One of the world’s most documented probiotic Lactobacillus strains, it has been described in over 201 clinical studies and attributed to beneficial effects in the gastrointestinal and immune system including;

  • Enhanced immune response
  • Reduction in the incidence of upset stomach
  • Reduction in symptoms of cold and flu

The ProGel coating then protects the probiotics on shelf and then maximises their delivery to the gut, all for your benefit.

Currently there is limited regulation in this area at present and drinks can often claim to be cultured without substantiating their probiotic nature. In some cases, not outlining their probiotics and what they may or may not do for you.

How is PERKii low in sugar and bitter-free?

Many people think all probiotic drinks need to taste bitter [kombuchas, kefirs] or have a large amount of sugar [yogurts, fermented milk shots] to main appeal. NOT TRUE.

An effect of the organic PROGEL™ microgels provides a stable environment for the probiotics and controls fermentation and release of acid bi-products in the living cultures. This removes the bitter effect often associated with these drinks, or the need for sugar to allow survival or mask taste.

Result is the ability to create a world-first probiotic water with a truly refreshing taste with more varieties to come [watch this space for some sparkling news!].

Do you need a probiotic?

Probiotic levels can be affected by a wide range of factors including poor diet (too much fats or processed foods or too little fibre), excess stress, toxic substances (including antibiotics) and excess alcohol intake.

While a good diet and exercise is the first line of defence, the large demands of the modern-day life can limit our ability to achieve our goals. Understanding the potential benefits of probiotics, can help you consider how adjusting your intake [of probiotics] may best benefit you.
