Before consumers remember to take their multivitamin, hit their protein target, track their water intake, or open a wellness app, many have already completed one non-negotiable daily ritual: making a coffee. This habit is so deeply ingrained that it happens automatically for millions of people, which explains why a growing number of brands pursue it as the perfect vehicle for health ingredients. From protein-fortified blends and adaptogens to cognitive-support ingredients and gut-health formulations, functional coffee promises consumers the opportunity to pursue multiple health goals through an activity they already perform every day. The concept is often described as "wellness stacking", which bundles several beneficial behaviours into a single habit. As functional coffee moves from niche wellness brands into the mainstream, an important question is emerging regarding whether it genuinely helps people build healthier lifestyles or if wellness culture simply found another way to package optimisation into the morning ritual.
The psychology behind the routine
Dr Phillippa Lally, a Senior Lecturer in Psychology at the University of Surrey specialising in habits, behaviour change, and health psychology, argues that part of the answer lies in how people adapt their actions. "People lead busy lives and therefore are looking for ways to meet their goals as easily as possible," she says. "If they want to live a healthy lifestyle there are so many messages about what we should all be doing that the idea of doing one thing that covers a lot of bases is appealing." Rather than adding new routines, many people incorporate health goals into habits that already exist. According to Dr Lally, these smaller, more incremental changes are easier to action and easier to turn into a new habit. Consumers might stir protein powder into their morning coffee, add collagen to an iced latte, or choose ready-to-drink products containing ingredients linked to focus, energy, or recovery. Instead of creating entirely new behaviours, they attach wellness goals to an established routine. Jessica Cording, a registered dietitian and author of The Little Book of Game Changers and The Farewell Tour, notes that these habits are becoming more visible thanks to the rising popularity of wellness stacking. "Wellness stacking is when you combine several wellness-promoting habits into one moment or ritual, or adding several functional ingredients into one food or beverage," she says. "I don’t think this is a new phenomenon. Habit stacking has been a part of the wellbeing conversation for many years, but with social media and more companies picking up on the fact that this is a marketing angle, we’ve been seeing it pop up more."
Consumers may often think a successful behaviour change depends on motivation or willpower, but researchers have repeatedly shown that consistency and environmental cues are often more important. "It’s not that a coffee ritual is more useful than any other habit," Dr Lally says. "It’s simply that, for many, this is a well-established habit that happens every day regardless of what else is happening. This makes it a good place to add in new behaviours to the established sequence." Unlike a supplement that may be buried at the bottom of a bathroom cabinet, or a wellness app stacked beneath notifications on a phone, coffee is often prepared in the same location and at the same time day in, day out. "That means an individual can look at their coffee-making environment and change it to remind themselves to add in the new actions," Dr Lally says. This may explain why functional coffee seems to resonate with today’s increasingly time-poor consumers. While previous generations often approached health through separate products and routines, younger consumers are seeking efficiency. Emily Lucci, Vice President of Marketing, Coffee at J.M. Smucker, says the opportunity is obvious for coffee brands. "Functional coffee is one of the fastest growing segments in coffee," she says. "As the leader in the at-home category, we have a responsibility to deliver on consumer needs and believe we can make functional coffee more accessible through trusted quality, scale, and affordability." Accessibility extends beyond distribution alone. "We are excited about the opportunity to help make functional coffee more accessible. Consumers will be able to find these products where they already shop for coffee," she says. "In addition, the offerings are easy to understand because each product is centred around a specific consumer benefit. Lastly, the products are priced to make trials approachable for everyday coffee drinkers."
Nutritional reality versus marketing claims
Yet if functional coffee succeeds commercially because it reduces friction, questions remain about whether it delivers meaningful nutritional outcomes. This is where Cording believes the conversation becomes more complicated and nuanced. From her perspective, the value of functional coffee depends less on marketing claims surrounding individual ingredients. Instead, it depends on how those ingredients fit within a person’s overall health needs. "It’s important to remember that simply adding a functional ingredient to your coffee doesn’t automatically offset negative health habits or prevent or cure a disease," she says. "Younger consumers have more awareness of wellness trends and products designed to support specific wellness goals. In some ways this is wonderful, as they are more motivated to be proactive about their health." "The shadow side of that can be they struggle with information overload and may be spending more time, money, or energy on things they might not need, or they end up feeling confused or overwhelmed." The broader shift is not limited to coffee. Cording notes that as more consumers moderate or eliminate alcohol consumption, many are looking for beverages that deliver relaxation, enjoyment, or other functional benefits, creating opportunities across the wider drinks industry. Lucci says brands such as J.M. Smucker are responding to varied consumer priorities. "Our team reviewed the current marketplace and consumer research to better understand what coffee drinkers would most appreciate in coffee with functional benefits," she says. "The four offerings reflect those benefits that we saw as being most attractive to our target audience." For consumers navigating a market filled with functional claims, Cording argues that greater scrutiny from consumers is needed. "Not everything is for everyone at all points of life," she says. "A few questions to ask are: What am I actually hoping this ingredient or product will do? What does the research say about this ingredient? Is the dose in this product similar to what’s in the research?" "What else am I taking? Are there any potential interactions? Am I getting this ingredient in any other products I use? If there is no overlap, will this ingredient stack in a helpful way with other things I’m taking?" She points to situations where adding protein to coffee can help consumers hit nutritional requirements they might otherwise miss. "If adding protein and creatine powder to coffee is helping a busy mum fuel her body after an early morning workout, when she would otherwise not have anything because she’s so busy getting the kids ready for the day, it can be helpful," she says. "Or for someone on a GLP-1 agonist who’s dealing with very low appetite, coffee with protein could help them get in a little extra to support muscle retention." "But even when we dress it up with functional ingredients, coffee is not a balanced meal. Consumers could also be unknowingly overdoing certain ingredients. If a morning coffee, evening wind-down drink, and snack bar all have Ashwagandha, for example, that’s asking a lot of the liver to process all that." In that scenario, the coffee is not the health intervention, rather it’s the delivery mechanism for a beneficial behaviour. In many ways, this may be the central argument in favour of functional coffee. While nutrition experts continue to debate the effectiveness of individual ingredients and formulations, behaviour scientists have long recognised that even the most evidence-backed intervention provides little value if people fail to adopt it consistently. Functional coffee sits in the middle of both realities, as a wellness product built around a habit consumers already practice every day.
