April marks Stress Awareness Month, a timely moment to reflect on how stress is shaping consumer behaviour and what it means for the health and nutrition industry. This year, the conversation is increasingly centred on one generation in particular: Gen Z.
Data from FMCG Gurus paints a picture of a generation under real pressure, meaningfully influencing how younger consumers think about their health, their diets, and the products they choose. For formulators, it’s important to understand the key market context, and the growing opportunity in gut health-centric support.
A generation navigating cognitive overload
Younger consumers are increasingly living in a constant state of cognitive overload. The pervasiveness of digital devices, alongside the demands of modern working and social life, is having a measurable impact on how the Gen Z generation experiences stress and mental clarity.
Only 36% of Gen Z say they are satisfied with their stress levels, compared to 52% among Baby Boomers. This difference shows a fundamentally different relationship with stress across generations.
Screen time is a significant contributing factor. According to FMCG Gurus, 46% of Gen Z and Millennials say they are concerned about the amount of time they spend on digital devices. This sits alongside a broader pattern of reported cognitive difficulty: 61% of Gen Z and 60% of Millennials say they feel distracted or unable to concentrate. These are the conditions that many younger consumers are navigating daily, and they are actively looking for ways to address them.
Motivation to act is high
What makes this consumer cohort particularly interesting for the health and nutrition market is that awareness of their stress is translating into intent. Almost half of Gen Z, 46%, say they plan to improve their mental wellbeing in the next 12 months.
That is a significant proportion of a generation that is digitally fluent, research-oriented, and increasingly proactive about health. The appetite is there, and the question for brands and formulators is whether their products are positioned to meet it.
Functional and fortified food and drink are already gaining traction with this audience: 59% of global Gen Z consumers report consuming products in this category. Meanwhile, 36% have already used supplements to support their health, a figure that, given their age profile, is likely to grow as health awareness deepens across the life stage.
Diet quality is a compounding factor
Stress and diet are closely intertwined, and here too the data raises important considerations. Busy, pressured lifestyles are taking a toll on nutritional quality: 18% of Gen Z rate their diets as poor or very poor, the highest proportion among all age groups.
This creates a dual challenge: a generation that is stressed and simultaneously falling short on nutritional quality in meaningful ways. But it also points towards a solution: Gen Z are looking for convenient, accessible routes to a healthier diet and lifestyle, not complex programmes or demanding regimes. Products that deliver genuine health benefits efficiently, and fit naturally into daily routines, are well placed to resonate.
Efficacy is non-negotiable
Gen Z are not passive consumers. They research, scrutinise labels, and have a healthy scepticism of health claims that are not backed by evidence. FMCG Gurus data shows that 44% of Gen Z consumers say that health and benefit claims are important when seeking out products.
For formulators, this is a direct challenge to ingredient selection. It is not enough to gesture towards mental wellbeing on a label. Gen Z, more than perhaps any previous generation, will investigate whether a product can actually deliver, and that means the science behind the ingredient must be robust.
Brands responding to the mental wellbeing opportunity need to consider not just format and positioning, but the credibility of what is inside the product. Demonstrable efficacy is increasingly essential.
Can prebiotics support mental health?
Emerging research suggests they can play a meaningful role. By selectively nourishing beneficial gut bacteria, prebiotics can influence the gut-brain axis through neurotransmitter production, stress hormone modulation, and immune pathways, all of which have a bearing on mood, stress regulation, sleep, and cognitive function.
The gut-brain axis: a science-backed route to mental wellbeing support
One of the most compelling areas of emerging nutrition science in this context is the gut-brain axis, the bidirectional communication network between the gut and the brain. Research suggests that the gut microbiome plays a meaningful role in stress regulation, mood, sleep, and cognitive function, opening up the possibility that supporting gut health may in turn support mental wellbeing.
The mechanisms are increasingly better understood. The gut produces many of the same neurotransmitters or precursors thereof as the brain, mainly through beneficial bacteria, particularly bifidobacteria, that reside in the large intestine. The gut microbiome can additionally influence the hypothalamic-pituitary-adrenal (HPA) axis, a central part of the body’s stress response system.
For formulators working in mental wellbeing, cognitive health, or stress support categories, these pathways show a credible and scientifically grounded area to address through product development. The key is ensuring that any ingredient used to target this space has the clinical evidence to support its use.
Bimuno® GOS: proven prebiotic support for stress physiology and emotional wellbeing
Bimuno® GOS is one of the most rigorously studied prebiotic galactooligosaccharide ingredients available to formulators today. As the most extensively studied GOS prebiotic for adult nutrition, backed by over 130 scientific publications, including more than 25 human clinical studies, it offers a depth of evidence that is difficult to match.
The research covers areas including gastrointestinal, immune and sports health, and importantly in this field, cognitive and mental health and wellbeing. A separate clinical trial in individuals with IBS found that GOS supplementation over four weeks was associated with reduced anxiety and improved quality of life versus placebo.
These findings sit within a wider body of evidence demonstrating that Bimuno GOS selectively nourishes bifidobacteria in the gut, supporting the microbiome pathways most relevant to gut-brain communication.
For formulators seeking to respond to the growing Gen Z demand for credible mental wellbeing solutions, Bimuno GOS offers a scientifically validated, consumer-relevant prebiotic ingredient. Crucially, one that addresses the gut-brain axis with a level of clinical backing that speaks directly to the efficacy-conscious consumer.
