About us

We are a small New Zealand family owned and operated business, based in Hikuai on the Coromandel Peninsula.  Together, Damian (Director & Sales), and Elizabeth (Marketing, Admin, etc) run the business from home whilst raising son Hawk (4). Damian's Mum now also helps with packaging and posting all the orders. 

Across the Tasman, we are lucky to have our very good friend Cassie managing the Australian branch of Immunity Fuel from her home in the Gold Coast. 

Together, our mission is to help people to live happy, healthy lives, and we do this by bringing the best probiotics in NZ to the world.

Why is this so important? We are passionate about the pairing of health & nature, and believe that everybody can enjoy good health if we just bring it all back to nature - and this is why we provide a natural formula that will bring out the best in your health!

Damian Johansen

Founder / Director

Damian grew up in the Coromandel, and learnt from a young age about Maori foods and medicines through his family's adventure tourism business. He has gone on to run his own successful tourism business and has built a good understanding of how nature can heal our bodies. Damian became interested in probiotics after meeting and becoming friends with Czerral, the developer of the probiotic superfood formula. Under Czerral's tutorship, Damian began marketing his own formula, which he called 'Immunity Fuel'. Damian is interested in all facets of human health & wellbeing, and has learnt in-depth information from Czerral about natural healing. 

As a user of the product for 3 years prior to having his own formula, Damian can wholeheartedly vouch for its unique ability to maintain good gut health functions.  Damian suffered from a combination of glandular fever, a kidney virus and chicken pox in his 20's and felt his health never fully recovered, however with the help of the probiotic superfood, he has regained his energy and vitality, as well as losing weight – dropping 10 kg's in 2 years which he has since maintained.

Elizabeth grew up on a sheep & beef farm in Southern Hawkes Bay, and has a Commerce degree in Marketing and an Arts degree in Anthropology from the University of Otago.

After meeting Damian Elizabeth moved to the Coromandel and is enjoying working full time on the marketing and administration (& everything else!) for Immunity Fuel.

Elizabeth & Damian had their first child in 2015, and Elizabeth took Immunity Fuel probiotic superfood throughout the pregnancy, which helped to maintain energy levels and keep regular, as well as supply all the essential nutrients to the baby to assist growth & development. Elizabeth continued to take Immunity Fuel whilst breastfeeding, and since baby Hawk began solids he has had a pinch of Immunity Fuel added to his porridge every day. As he grows this dose has increased to about 1/2 a teaspoon.

Cassandra Brown

General Manager, Immunity Fuel Australia.

Cassie grew up In Tweed Heads, Australia with a love for the coast and as a health researcher with an interest in staying healthy and happy naturally with fewer to no use of medications.
Whilst travelling around Europe in 1999, Cassie suffered a severe case of food poisoning resulting in hospitalisation twice and a near death experience. Her digestive system has never quite recovered, until she discovered Immunity Fuel probiotic superfood! Over the years Cassie had tried many formulas of probiotics, digestive enzymes, green powders, vitamins, minerals and had been to see several naturapaths. Whilst this made a difference it was not sustainable and the relief never lasted. Cassie has now been taking Immunity Fuel for two years and with a remarkable difference to her digestive system, no other product is required, its everything she needs all in only one teaspoon a day.

Cassie has now chosen to leave a successful advertising sales career to follow her passion for health and inspire others to live a healthy, happy and natural life too. Completing a certificate in Natural Choices, 200HR certificate in Yoga Teacher Training and certificate in creative kids yoga, she is now Australia's distribution manager for Immunity Fuel and teaching yoga on the Gold Coast.

Where Immunity Fuel came from...

The formula for Immunity Fuel probiotic superfood was the brainchild of Czerral, D.V. Med, MMBM, who resided in Tairua on the Coromandel Peninsula. Czerral was interested in and studied nutrition for over 35 years, first introducing the very first "super food", Spirulina, to the world in 1979. Later in 1994 he developed and introduced the first Certified Organic, fermented prebiotic & probiotic superfood, and it is this development that the formula for Immunity Fuel is based on.

Damian, Founder & Director of Immunity Fuel was lucky to meet and become friends with Czerral and his wife Diviana in Tairua. Czerral and Diviana have shared with Damian a wealth and depth of knowledge about how our bodies function and respond to natural products. They have reiterated the view of looking at everything from a natural perspective and that the only way to get well is to go 'back to nature'. New Zealand is one of the most obese countries in the world per capita and the amount of allergies and health related issues that people are experiencing are increasing exponentially. However disease is simply the malnutrition of the cells and if we give our cells nourishment with natural nutrients and replace the good bacteria for our immune and digestive system, the body has an amazing ability to repair itself.

"The cause of all disease is simply the malnutrition of cells.
Once we understand this then we can reclaim our birthright, 'HEALTH'"

Our Mission

With Immunity Fuel, our mission is to give the people of New Zealand, Australia and the world the opportunity and tools they need to restore and reclaim their health. This probiotic superfood is results orientated and the health benefits that people have experienced while using it have been amazing. It is important to remember that this is a completely natural product, with no GMO, no dairy, and no artificial flavours or colourings. The product is also unique in the fact that it is classed as a raw fermented food, containing all 13 strains of the Lactobacillus family plus Certified Organic wholefoods so it is a probiotic with nutritional value – an all-in-one SUPER FOOD! We love this product and want to share it with all New Zealanders so everyone has the opportunity to be healthy and happy.
The company and product name Immunity Fuel is based around IMMUNITY - the immune system support provided by the 13 bacteria in our formula, and FUEL - the fuel our bodies receive from the wholefood nutrients. Immunity Fuel is unique to New Zealand, and works on the principle of restoring good bacteria to the gut and the nutrients to the cells the body requires to heal itself.

“For me not to have any colds or flus for over 3 years is awesome as I am self employed and can't afford to be sick. To have the energy that I had when I was 20 again is just amazing and my ability to deal with stress has also improved. All round it is the best natural product I have ever come across!"


“I have been taking Immunity Fuel for several years now, and love the increased energy levels I have experienced. As the product is all natural I know it is good for me and for our boy Hawk, who has been taking it since starting solids at 5 months of age. It's peace of mind to know he is getting all the goodness our bodies need to grow and build strong immune systems."

I was spending around $200/month on a probiotic, digestive enzyme, B complex and a greens powder to assist my digestive health, now all I need is the one product "Immunity Fuel" and my digestive system is now working better then ever. My food is being digested, I'm able to eat and drink pretty much anything I want again and I'm removing toxic waste every day rather then only 1-2 times a week like I was before Immunity Fuel. I feel less bloated, I have more energy and my skin is glowing. I love this product and now I want to help others live a healthy and happy life too"
