5 Functional Beverage News Trends UK Drinks Brands Can’t Ignore

Walk down any supermarket aisle in the UK right now and the soft drinks fridge looks nothing like it did five years ago. Lion’s mane mushroom lattes sit next to alcohol-free IPAs, electrolyte sachets compete for shelf space with kombucha, and CBD drinks have quietly become a fixture rather than a novelty. This is what functional beverage news actually looks like in 2026: not a fad cycle, but a structural shift in what British shoppers reach for when they want a drink that does more than taste good.

What Counts as a Functional Beverage Right Now

The term gets used loosely, but the latest functional beverage news from UK industry trackers tells a consistent story. The UK’s Fruit Drink & Functional Beverage Production industry, tracked by IBISWorld, puts the category’s domestic market size at £2.2 billion in 2026, having grown at a compound annual rate of 5.6% between 2020 and 2025. That includes sports and energy drinks, fortified water, kombucha and the newer wave of adaptogen and nootropic drinks that didn’t really exist commercially a decade ago. Mordor Intelligence values the worldwide market at roughly USD 163.84 billion in 2026, forecasting growth to USD 239.95 billion by 2031, driven by consumers shifting from basic nutrition to chasing specific outcomes like gut health, sleep, energy and stress relief.

Electrolyte and Sugar-Free Drinks Are the Quiet Winners

While mushroom drinks get the headlines, the real functional beverage news story in volume terms is electrolyte and sugar-free hydration products doing the heavy lifting. The British Soft Drinks Association’s 2024 annual report recorded that UK consumption of sports and energy drinks reached 1.2 billion litres, up from 1.1 billion litres the year before. Within the broader functional drinks market, Grand View Research’s UK databook shows energy drinks and shots held over half of total revenue share in 2024, with sports drinks tipped as the fastest-growing type segment going forward.

Part of this is regulatory. The UK’s Soft Drinks Industry Levy has pushed manufacturers toward reformulating with natural sweeteners and lower sugar counts, and IBISWorld’s analysis of the sector notes producers are leaning into low- and no-calorie variants to stay inside levy thresholds while keeping the functional positioning. For small drinks brands, that’s a genuine opportunity: shelf space is opening up for sugar-free electrolyte products that don’t taste like a hospital drip, historically the category’s biggest complaint.

Mushroom Complex and Adaptogen Drinks Have Moved Past Novelty

Functional mushroom drinks built around lion’s mane, reishi, cordyceps and chaga were a niche curiosity in the UK as recently as 2023, and they’re now one of the biggest functional beverage news stories in the category. According to DataM Intelligence’s market research, the UK functional mushroom market reached roughly USD 1.85 billion in 2024 and is projected to hit USD 4.42 billion by 2032, growing at an estimated 11.5% CAGR.

The Grocer’s reporting on the category points to real commercial traction behind that forecast: Muush, a UK mushroom drinks start-up founded by Dan D’Souza and Matt Martin in 2024, raised over £400,000 in its first year and was on track to reach £500,000 shortly after. D’Souza’s pitch to the trade press was blunt: people want low-sugar, alcohol-free drinks that taste good first and deliver a functional benefit second, not the other way round. YouGov data shared with The Grocer found that close to half of UK consumers know little to nothing about what functional mushrooms actually do, which means taste and marketing, not health claims, are doing most of the conversion work for these brands right now.

Kombucha and Gut Health Drinks Are Outgrowing the Wider Soft Drinks Category

Kombucha has moved well past health-food-shop status. Grand View Research puts the UK kombucha market at USD 170.9 million in 2024, projected to reach USD 554.1 million by 2033, a 14% compound annual growth rate, with hard kombucha (the alcoholic variant) growing even faster at an estimated 18.7% CAGR. IndexBox’s UK-specific analysis goes further, estimating the wider kombucha and gut health beverage category grew at 18 to 24% a year between 2020 and 2025, several times faster than soft drinks generally.

The catch is the same one running through this entire category: under retained EU and UK Food Standards Agency rules, brands can’t make a specific “gut health” or “probiotic” claim without authorised backing, which is why most labels stick to softer language like “live cultures” rather than promising digestive benefits outright. Sugar is the other live issue, with flavoured kombucha often still carrying 8 to 12g per 250ml serving, putting it under the same levy pressure facing the rest of the category.

Hemp and CBD Drinks Face a Tighter Regulatory Lane Than Most People Realise

CBD drinks were the first wave of this trend in the UK, and they’re still part of it, but the regulatory ground has shifted underneath them. Any drink claiming a specific health benefit, including relief from anxiety or nausea, falls under the Advertising Standards Authority’s food health claims rules, which require claims to sit on the GB Nutrition and Health Claims Register. The ASA’s guidance on functional foods is explicit that calling a product “functional” is itself treated as a general health claim requiring an authorised claim to back it up.

This matters commercially because CBD and hemp brands have increasingly diversified into adjacent ingredients rather than leaning harder on CBD-specific claims. Trip, one of the UK’s better-known CBD drinks brands, expanded into a separate mushroom and adaptogen-led range built around lion’s mane, ashwagandha, magnesium and L-theanine, framed as calm-focused rather than medicinal. That reflects how UK drinks brands are learning to market wellness benefits without tripping into claims they aren’t authorised to make.

The Non-Alcoholic Drinks Boom Ties Every Trend Together

If there’s one thread running through all of this, it’s moderation. The British Beer & Pub Association reported that low and no-alcohol beer sold a record 200 million pints in the UK in 2025, almost 3% of the total beer market, with 87% of pubs now serving at least one no or low alcohol beer.

The Portman Group’s eighth annual survey, run with YouGov in early 2026, found that 86% of UK adults either abstain entirely or drink within the 14-units-a-week guideline, and 24% of drinkers who’d tried a low or no-alcohol alternative said it had reduced their overall alcohol consumption.

This is also where the most interesting crossover is happening. IWSR’s UK market notes call out brands like Collider, a no-alcohol beer infused with functional mushrooms, as an example of the no/low and functional categories starting to merge. If you’re weighing up whether a UK drinks brand is worth backing right now, the same instinct that applies to the best cognac brands outclassing whisky at every price applies here: category crossover, not pure novelty, is where the margin tends to sit.

What This Means If You’re Building or Launching a Drinks Brand

For founders reading this as more than consumer trivia, the signal is consistent across every trend above: taste-first positioning beats health-claim-first positioning, low sugar is table stakes rather than a differentiator, and regulatory literacy around the ASA’s health claims rules stops being optional once a brand scales past a market stall.

Anyone starting an online drinks business should treat the practical groundwork covered for new UK home and online businesses as just as important as product formulation, since distribution and compliance are where most brands actually stall, not flavour development. It’s also worth borrowing from how UK service brands have approached marketing strategy to win local and online leads, since the playbook for building word of mouth before a product has retail history translates directly into drinks.

Frequently Asked Questions

Is the UK functional beverage market actually growing or is this overstated?
It’s growing, and the functional beverage news around it backs that up. IBISWorld puts the domestic fruit drink and functional beverage production industry at £2.2 billion in 2026, with multiple independent forecasts pointing to continued growth through 2030.

Do CBD drinks actually help with nausea?
UK advertising rules don’t currently allow CBD drink brands to make a specific medical claim like nausea relief unless it’s authorised on the GB Nutrition and Health Claims Register, so most reputable brands avoid making that claim directly, regardless of anecdotal reports.

What’s the difference between hemp drinks and CBD drinks?
Hemp drinks generally use hemp seed or hemp extract for flavour and nutritional content, while CBD drinks specifically contain cannabidiol extracted from the plant, which is the compound subject to the tighter health claims scrutiny described above.

Why are mushroom drinks becoming popular in the UK?
Growth is being driven by consumer interest in alternatives to caffeine and alcohol that still offer a functional benefit, with UK-specific demand reflected in projected market growth from roughly USD 1.85 billion in 2024 to USD 4.42 billion by 2032.

Are non-alcoholic beers actually reducing how much people drink?
According to the Portman Group and YouGov’s 2026 survey, 24% of UK drinkers who tried a low or no-alcohol alternative said it had reduced their overall alcohol consumption.

Final Thoughts

What strikes me most about this wave of functional beverage news is how unglamorous the winning strategy actually is. It isn’t the boldest health claim or the trendiest mushroom that’s moving units, it’s brands solving the boring problem of making a healthier drink taste like something you’d choose twice. Anyone building in this space in the UK should treat regulatory compliance as a product feature, not paperwork, particularly given how exposed health claims are to scrutiny under the government’s nutrition and health claims guidance. Get the taste and the compliance right together, and the rest of this category still has years of growth left in it.
