The hidden burden of gut health
Our survey of 811 adults reveals how widespread, multi-symptom and life-affecting gut health issues really are - and how poorly current options meet the need.
Modern diets are packed with ultra-processed, high fat, sugar and salt foods, contributing to record levels of obesity, diabetes, cardiovascular disease, gastrointestinal conditions, poor sleep, chronic stress, and more.
Our gut is the control centre for our physical and mental health, our daily wellbeing and our weight, yet education on how to create and support a healthy gut is shockingly poor. In fact, it’s completely absent from our education and healthcare systems, and we want to change that.
The first step to achieving better health is by achieving better gut health, and you can do this through simple, actionable changes, including understanding your poo!
*Based on 32,000 responses to the DRV+ quiz.
Your gut is responsible for the digestion and absorption of nutrients which are the building blocks for almost everything in your body, from your energy, immune health, your stools and your sleep, to your concentration, skin health and much more!
When your gut is out of balance it will be sure to let you know. In our gut survey, 44% of people said their gut health restricts how they go about their daily life, a third of people avoid social contact and going out as a result of their gut health, while 30% of people experience mild depression.
Here are the top signs to look out for that may indicate your gut is in need of some love.
Skin conditions
Skin conditions
Healthy bowel movements sweep toxins out of the body, if natural detoxification doesn't occur, toxins will be reabsorbed through the gut, and the body has to push them out through the skin, causing redness and acne.
Poor concentration
Poor concentration
The main chemicals needed for concentration are acetylcholine, dopamine and noradrenaline, and they're produced in the gut by probiotics. Disruptions to probiotic numbers will decrease these chemicals and in turn your ability to concentrate and focus.
Gas and bloating
Gas and bloating
Gas and bloating can occur for a few reasons. Low stomach acid and enzyme production can inhibit the breakdown of foods, fibres, sugar, fats or protein, and allows bacterial fermentation which creates gas and bloating.
Constipation
Constipation
Constipation is an obvious sign of an unhealthy digestive system. Constipation can be caused by a lack of probiotics, which provide most of the weight of faecal matter.
Diarrhoea
Diarrhoea
Diarrhoea occurs when the gut is irritated due to parasites, detrimental bacteria, poorly digested foods or food sensitivities.
Insomnia
Insomnia
Insomnia is a common problem and affects life quality. Research shows you're more likely to suffer poor sleep or insomnia if you suffer poor digestion or IBS.

A troubled gut, poor digestion and IBS are very common problems. Our own customer survey shows that more than 4 in 10 people regularly suffer digestion issues, and 1 in 4 people suffer symptoms of IBS (Irritable Bowel Syndrome).* Poor gut health can not only be uncomfortable and debilitating, it is also likely to cause other physical and mental symptoms that may affect your day-to-day life.

Our survey of 811 adults reveals how widespread, multi-symptom and life-affecting gut health issues really are - and how poorly current options meet the need.
Our survey of 1,526 women shows that gut health deteriorates for most women during menopause - usually beginning in perimenopause.
Because poo is not something widely discussed, many people are left wondering if their poo is normal and they're unaware of the signs of ill health that it can point to. There are many variations of poo, and each one indicates an area of health that is either in or out of balance in our gut.

Probiotics are one of the fastest-growing supplement categories, and they're used by hundreds of millions of people across the world. The biggest driver of the growth in probiotics has been the new research and evidence released over the past 10 years. The key focuses of this research includes the role probiotics and prebiotics play in our overall wellbeing, from gut health to skin health, mental health, immunity and much more.

CFU stands for 'colony-forming units', which refers to the number of live and active microorganisms that you can expect in a probiotic supplement. This is determined in the laboratory, and CFU tells us the viability and number of microorganisms in the probiotic prior to exposure to the gastrointestinal tract. The active microorganisms tend to live and grow together as colonies, even though we sometimes refer to them as individual bacterial strains. CFU essentially refers to the beneficial bacteria that you can expect, as a total count per dose.
The number of CFUs is one important factor to consider when taking a probiotic, but it's not the only factor. Probiotics are expensive to manufacture, so a higher CFU can often be a good indication of quality or whether a probiotic is value for money or not, however, it doesn't necessarily mean it has better efficacy or outcomes. Likewise, a low CFU count may (or may not) be adequate for your particular health goal. Most probiotic supplements have a range between 1-20 billion CFUs of live bacteria per dose, while there are some that have 50 billion or more, and there are others with 100 billion and more
Combinations of probiotic strains have had robust research for a number of different purposes. The human body’s microbiome contains over 800 different bacterial species, so it is inherently diverse and naturally a multi-strain, multi-species environment. It is therefore generally believed that we need to help repopulate the microbiome with a combination of strains to complement our natural flora, rather than one specific strain.
The vast majority of clinical studies have shown that probiotics exert beneficial effects on gut health issues ranging from IBS, bloating and gas, to acid reflux and constipation. But we also know that by restoring the intestinal balance of harmful microbes with healthy bacteria, the beneficial effects experienced reach far beyond gut health. There are bi-directional relationships that exist between the gut and other organs that have been referred to as the gut-brain axis, the gut-skin axis or the gut-vagina axis, for instance. The gut also plays a vital role in regulating our hormones and many other health issues.
The short answer to this question is YES. Prebiotics are plant fibres that are not digested by your body, which means they travel through your stomach to your digestive tract, where they feed and support the probiotics in your gut. When probiotics feed off prebiotics, they produce lactic acid and short-chain fatty acids that improve the digestion of foods and the overall health of your gut microbiome. Put simply, without prebiotics, probiotics are not nearly as effective.
Postbiotics are considered to be the compounds created by bacteria during the fermentation process. They are the beneficial end products of bacteria. Unlike prebiotics, postbiotics do not contain live microorganisms; however, they can still be effective in their own right. Postbiotics can contain nutrients like Vitamins B and K, as well as substances that slow down the growth of unhealthy bacteria.
Whether you need a probiotic or not is up to the individual, their circumstances, their health status and the health concerns they are seeking to improve. Generally, healthy people might just want to take a probiotic daily to keep their immune system in check, support their gut health when travelling and eating new cuisines or improve their skin condition.
Many systems in the body rely on probiotics to function effectively. Probiotics help with the digestion of food by producing digestive enzymes, they support the function of the immune system, promote effective detoxification, they help to maintain healthy skin, and they create neurotransmitters when they travel to the brain. Having multiple probiotic strains is also a bonus as each strain provides a different action in the gut. It is estimated there are over 40,000 different strains of probiotics in the gut, so it makes sense to take a multi-strain formula.
