A few years ago, choosing a soft drink was mostly a question of flavour. Today, consumers are increasingly looking at the ingredients list and asking what else the product might do for them.
Can it improve hydration? Support digestion? Provide protein? Help with concentration? Offer an energy boost without the sugar crash? Replace the ritual of an alcoholic drink at the end of the day?
That shift has created one of the fastest-growing parts of the drinks industry. Functional beverages, once largely confined to health-food shops and sports nutrition, are now appearing in supermarkets, gyms, cafés, bars and workplace fridges.
The category is broad. It covers established products such as energy drinks, sports drinks and protein shakes, but also a newer generation of kombuchas, prebiotic sodas, electrolyte waters, collagen drinks, nootropic shots and alcohol alternatives made with botanical or supposedly mood-enhancing ingredients.
Not all of these products are equally credible, and not every ingredient will survive the next cycle of wellness trends. The wider movement, however, looks unlikely to disappear.
A market moving into the mainstream
Grand View Research estimates that the global functional drinks market was worth $164.7 billion in 2025. It forecasts that the market will reach $315.9 billion by 2033, representing annual growth of around 8.5% between 2026 and 2033.
Energy drinks and shots remain the largest part of the category, accounting for 51.8% of global revenue in 2025. That is worth remembering when discussing the “rise” of functional drinks. The market did not suddenly begin with mushroom coffee and prebiotic soda. Consumers have been buying drinks for energy, performance and recovery for decades.
What has changed is the number of functions being offered, the range of occasions being targeted and the type of consumer buying into them.
The UK market is showing particularly strong growth. Circana data reported by The Grocer valued British functional health drink sales at £143.5 million in the 52 weeks ending 25 January 2025. That was an increase of 26.4%, or £23.8 million, in a single year.
Across Europe, spending on sports and energy drinks rose by 7.7% in the year to June 2025. Unit sales increased by 4.3% and volumes by 3.2%, suggesting the rise was not simply the result of higher prices. During the final three months of the period, value growth accelerated to 13.3%.
Why drinks work so well as wellness products
Functional drinks fit neatly into daily life. They do not usually require preparation, they can be consumed on the move and they replace something the customer might already have bought.
That makes them easier to adopt than many traditional supplements. Remembering to take several capsules every morning feels like a health regime. Picking up a flavoured drink after the gym feels like a refreshment purchase, even when the two products contain similar ingredients.
Younger consumers appear especially comfortable with this overlap between beverages, nutrition and wellness.
Research from EY found that 80% of Gen Z consumers in the United States drink functional beverages at least once every two weeks. The figure was 75% among millennials, falling to 64% for Generation X and 41% for baby boomers.
For younger adults, function is becoming a normal part of how a drink is judged. Taste, price and packaging still matter, but they increasingly sit alongside another question: what am I getting from this?
This does not necessarily mean consumers believe every health claim they encounter. It means they are open to paying for a product that offers an understandable and relevant benefit.
The move towards more specific benefits
The language used by functional drinks is becoming more precise.
Earlier wellness products often relied on broad ideas such as vitality, purity or general wellbeing. Those concepts can sound appealing, but they do not give consumers a clear reason to choose one product over another.
Newer brands are usually built around a recognisable occasion or outcome.
Electrolyte drinks, for example, are no longer marketed only to endurance athletes. They are aimed at gym users, travellers, festivalgoers, office workers and people recovering from a late night.
Gut-health drinks have expanded beyond kombucha into kefir, fibre-enhanced waters and prebiotic sodas. Protein drinks are increasingly presented as convenient breakfasts or snacks rather than bodybuilding products. Drinks containing magnesium, L-theanine and botanical ingredients are being positioned for the evening, when consumers might otherwise open a beer or pour a glass of wine.
Energy remains a major driver, but even here the proposition is changing. Alongside heavily caffeinated products, brands are offering drinks associated with concentration, sustained energy or a calmer form of alertness. Ingredients such as L-theanine, B vitamins, amino acids and plant extracts are commonly added to support that positioning.
NIQ recorded 258 new functional beverage launches during one 12-month period. Its research also identified growing activity around probiotics, prebiotics, adaptogens, nootropics and collagen, while clean-label functional products grew by 8%.
The level of innovation is impressive, although it is also producing a crowded market in which a surprising number of cans promise focus, calm, energy and inner balance at the same time.
A drink can now compete with a snack
Another reason for the category’s growth is that beverages are taking on occasions previously occupied by food.
Circana found that 68% of consumers sometimes have a beverage as a snack, seven percentage points higher than in 2021. Protein shakes, smoothies, drinking yoghurts and fibre-rich drinks can offer convenience and some feeling of fullness without requiring a sit-down meal.
This creates opportunities beyond the traditional soft-drink category. A functional beverage might compete with a cereal bar, yoghurt, supplement, coffee or light breakfast, depending on how it is formulated and positioned.
Ingredients once associated with specialist sports nutrition are also becoming more familiar to mainstream consumers. Circana reports that drink mixes containing creatine have generated more than $370 million in sales.
The increasing use of GLP-1 weight-management medication could influence this area further. People eating smaller portions may look for convenient sources of protein, fibre, hydration and micronutrients. Beverage companies are already responding with more nutrient-dense formats.
Brands should approach this carefully. Supporting the nutritional needs of consumers is different from suggesting that a standard commercial beverage can reproduce or enhance the effects of medical treatment.
Functional drinks and the decline of routine alcohol consumption
The category also overlaps with another major change in drinking behaviour: alcohol moderation.
Some consumers want a direct replacement for beer, wine or spirits. Others are less interested in imitation and simply want an adult drink that feels more interesting than a conventional soft drink.
This has encouraged the growth of botanical sodas, mood-focused drinks and products sometimes described as alcohol-adjacent beverages. They are designed for social or evening occasions, but do not necessarily attempt to taste like an alcoholic product.
IWSR estimated that global volumes of alcohol-adjacent drinks grew by 11% in 2025, although from a relatively small starting point. Conventional no-alcohol versions of beer, wine, spirits and ready-to-drink products grew by approximately 9%.
The two groups appear to meet different needs. No-alcohol beer, wine and spirits allow consumers to take part in familiar drinking rituals without consuming alcohol. Functional alternatives are more likely to be chosen for novelty, flavour or the perceived effect of their ingredients.
For bars and restaurants, this creates space for a better non-alcoholic offer. A well-designed functional serve can provide flavour, theatre and a reason to order a second drink. It is a considerable improvement on treating lime and soda as the inevitable punishment for not drinking alcohol.
Trust remains a weakness
For all the growth, the category has a credibility problem.
Kantar found that 27% of consumers in Great Britain say confusion about what is healthy prevents them from purchasing wellness products. Functional drinks can add to that confusion through unfamiliar ingredients, unclear quantities and vague promises around cleansing, balance, focus or immunity.
This is particularly important because functional products often command a significant premium over ordinary soft drinks. Consumers may accept the higher price when they understand the benefit and trust the formulation. Attractive packaging and a fashionable ingredient are rarely enough to sustain repeat purchases.
Brands need to be clear about what the product is for, how much of each active ingredient it contains and when it should be consumed. Sugar, caffeine, calories and serving size should also be communicated plainly.
Dosage matters. A label may feature a recognised functional ingredient, but that does not necessarily mean the product contains enough of it to produce a meaningful effect.
Health claims also have legal boundaries. In Great Britain, food and beverage companies may only use authorised nutrition and health claims from the official register. An ingredient’s traditional use, early-stage research or popularity online does not automatically provide a legal basis for promising better sleep, stronger immunity or improved cognitive performance.
The brands that communicate carefully may appear less exciting than those making larger promises, but they are more likely to build long-term trust.
Taste still decides whether people come back
A functional benefit might generate the first sale. Taste is more likely to determine the second.
Many functional ingredients are difficult to formulate. Some are bitter, earthy, acidic or medicinal. Covering those flavours can require sugar, sweeteners and complicated flavour systems, which may conflict with the natural or clean-label image of the product.
Consumers will sometimes tolerate an unpleasant concentrated shot when they believe the benefit is worthwhile. Expectations are different for a drink intended to be enjoyed with lunch, after exercise or during an evening out.
That distinction is likely to shape the market. Small shots and supplement-style products can prioritise potency and convenience. Everyday sodas, waters and adult soft drinks must still offer refreshment and pleasure.
No amount of clever branding changes the basic reality that people do not usually make a daily habit of drinking something they dislike.
Where the category goes from here
Functional drinks are becoming less of a separate category and more of an approach that can be applied across the drinks market.
Water can contain electrolytes. Coffee can include protein. Soda can carry prebiotic fibre. An evening drink can be designed around relaxation rather than alcohol. Even traditional sports and energy brands are adding benefits linked to hydration, recovery and concentration.
This will attract more investment and more launches, but it will also make the market harder to navigate. Products without a clear purpose will struggle, particularly as consumers become more familiar with ingredients and less impressed by generic wellness language.
The most convincing products tend to share a few characteristics. Their function can be explained in one sentence. The formulation supports the claim. The ingredients and quantities are transparent. Most importantly, the drink fits naturally into an existing moment in the customer’s day.
Functional drinks are growing because they sit at the intersection of several lasting trends: convenience, preventive health, alcohol moderation, personalisation and demand for better-quality non-alcoholic choices.
The opportunity is substantial. So is the potential for overstatement.
The brands that succeed will not necessarily be those promising the most. They will be the ones that offer a relevant benefit, explain it clearly and produce something people genuinely want to drink.
