Unlocking the Secret to a Long and Vibrant Life: Harnessing Gut Health for 100+ Years

Unlocking the Secret to a Long and Vibrant Life: Harnessing Gut Health for 100+ Years

In a groundbreaking study, researchers have delved into the fascinating world of microbiomes to uncover the secrets behind living a long and healthy life and sheds light on the remarkable connection between gut health and longevity.

The research (1), conducted by a team of experts at the Novo Nordisk Foundation Centre for Protein Research, explored the gut microbiomes of individuals in Japan who have reached the impressive milestone of 100 years or more.

The findings revealed a compelling correlation between the diversity and balance of gut bacteria and the participants' remarkable longevity.

The human gut is home to trillions of microorganisms, collectively known as the microbiome. These tiny organisms play a crucial role in various bodily functions, including digestion, metabolism, and immune system regulation. However, the study suggests that their influence extends even further, potentially impacting our lifespan.

“Previous research has shown the intestinal bacteria of old Japanese citizens produce brand new molecules that make them resistant to pathogenic, disease-promoting, micro-organisms.

“And if their intestines are better protected against infection, well, then that is probably one of the things that cause them to live longer than others.” Dr Joachim Johansen, Senior Scientist, Clinical Microbiomics

 Higher beneficial bacteria

By analyzing the gut microbiomes of centenarians, the researchers identified specific patterns and compositions that appeared to be conducive to extended life.
These individuals showcased a higher abundance of beneficial bacteria, while harmful strains were notably scarce. This intricate balance seemed to promote better overall health and resilience, contributing to their exceptional longevity.

Furthermore, the study found that the gut microbiome's health could be influenced by external factors such as diet and lifestyle choices. Participants who followed a diet rich in fibre, whole grains, and plant-based foods exhibited more diverse and robust gut microbiomes. Regular physical activity and stress management techniques were also associated with a healthier microbial environment.

The implications of this research are immense, as it offers valuable insights into how we can optimize our gut health and potentially extend our lifespan.

While genetics undoubtedly plays a role, the study suggests that making conscious choices to nurture our gut microbiome could have a significant impact on our overall well-being and longevity.

Prebiotics, gut & overall health

Prebiotics take dietary fibre to the next level in health benefits offered, such as reducing the risk of cardiovascular disease (2), type 2 diabetes (3) and colorectal cancers (4).

There are over 4,000 research studies proving the links between prebiotics and mood, sleep, weight management, digestive health, skin health and immune system function.


What is prebiotic fibre?

Prebiotics are an essential and unique type of fibre that feed healthy gut microbes (aka probiotics).  They help probiotics to thrive and flourish, ultimately creating a happier healthier gut microbiome - and a happier, healthier you!

 fibrewater: Proven to increase healthy gut microbes

After our own research and incredible results regarding people's noticeable health improvements after drinking one bottle of  fibrewater daily for 12 days, we knew that there was truly something special in our innovative water!

So we collaborated with Glasgow Caledonian University (GCU) and the department of Biological and Biomedical scientists to find out more...

 Glasgow Caledonian University study io fibrewater

The study conducted by Glasgow Caledonian University on  fibrewater found that our innovative prebiotic-infused water increased healthy gut microbes significantly.

You can read the Glasgow Caledonian University press release about this exciting study here.

An easy way to support gut & overall health

 fibrewater is the UK's first prebiotic-infused water that delivers precision nutrition with 100% of your daily prebiotics and 20% of your daily fibre intake, too!


Made with soluble prebiotic chicory root fibre (inulin),  fibrewater is completely clear, has no added sugar and is just 17 kcals per bottle.

With a splash of refreshing natural fruit flavour (Lemon & Lime or Strawberry), and no 'nasty' ingredients such as artificial sweeteners,  fibrewater is a great swap-up from other drinks, and tastes great, too!

Plus it's approved by the Vegan Society and is gluten-free.

Check out the numerous reviews regarding how  fibrewater is making a positive impact on people's health - and lives.

io fibrewater reviews

'One word. AMAZING! I'm not bloated and my stomach cramps are gone!' Alyosha P.

🥳'I have had digestive issues (IBS, hiatus hernia with acid reflux) and food intolerances for many years. My digestion has been so much easier from the first day of drinking  fibrewater.' Isobel G.

🤩'Absolutely love this water. I felt instant benefits after just a few days!  My energy levels improved and my sleep has been so much better!' Sigi G. 


As the scientific community delves deeper into the complex relationship between gut health and longevity, there is hope for the development of targeted interventions and personalized approaches to promote healthy aging.

With thousands of studies on prebiotics and a study on  fibrewater, we know that they support the gut microbiome and provide a plethora of health benefits. 

The findings of the Novo Nordisk study provide a solid foundation for further research and open up new possibilities for enhancing our quality of life as we strive to reach the remarkable milestone of living beyond 100 years.
