Functional Drinks in 2026: Why Gen Z and Millennials Want More From Every Sip
Updated: Oct 6
Your calendar has a workout, a deadline and dinner with friends. Your shopping basket has a drink that promises to keep up.
Sound familiar?
A beverage can now come with a job description: energy for an active day, hydration after exercise, support for digestion, or something that fits a calmer evening.
The functional drinks market is built around that idea and Gen Z adults and millennials are helping shape it.
But with so many claims on the shelf, the useful question is simple: What do you actually want your drink to do?
What are functional drinks?
Functional drinks are beverages marketed to offer benefits beyond taste and basic refreshment. Depending on the formula, they may contain electrolytes, protein, probiotics, vitamins, botanical ingredients or other nutrients. Common categories include energy drinks, sports drinks, probiotic drinks and beverages positioned around focus, relaxation or beauty from within.
“Functional” describes the product’s positioning. It does not, by itself, establish that a particular benefit has been demonstrated.
Why Gen Z and millennials are buying functional beverages
In EY’s Consumer Beverage Survey, released in March 2026, 80% of US Gen Z adults and 75% of US millennials reported drinking functional beverages at least every two weeks, compared with 65% of US respondents overall. 1
These are US findings, not worldwide or Singapore consumption rates.
The survey included adults aged 18 and over and was conducted in late 2025.
Still, the results help explain why functional beverages are receiving so much attention. They fit into routines people already have: commuting, studying, training, working and socialising.
For an adult Gen Z reader, the occasion might be a study session or a first full-time job. For a millennial, it might be an early workout before a busy workday or family commitments. Those are examples, not rules about either generation.
The shared question is whether the drink earns a place in the day.

Six familiar brands that show how the market works
These brands illustrate different parts of the category. This is not a ranked global top-six list: cans sold, company revenue, retail market share and daily bottle consumption measure different things.
Red Bull
Energy drinks
13.969 billion cans sold worldwide in 2025, according to Red Bull. 2
Monster Energy
Energy drinks
Monster Beverage reported US$8.29 billion in company net sales in 2025. This covers its portfolio, not the Monster brand alone. 3
Gatorade
Sports hydration
Formula 1’s partnership announcement describes Gatorade as the world’s leading sports and isotonic drinks brand. 4
Yakult
Probiotic cultured drinks
About 38 million bottles consumed daily in FY2024, across 40 countries and regions, according to Yakult. 5
Pocari Sweat
Hydration and electrolyte replenishment
Available in more than 20 countries and regions, mainly in Asia, according to Otsuka. 6
CELSIUS
Fitness-oriented energy drinks
10.9% of US ready-to-drink energy dollar sales in tracked channels for the 13 weeks ended 28 December 2025. This is US share, not global share. 7
Red Bull and Monster show the commercial scale of energy drinks.
Gatorade and Pocari Sweat make hydration a familiar reason to choose a beverage. Yakult gives the category a long-established probiotic example.
CELSIUS illustrates fitness-oriented energy positioning.
For readers in Singapore and across Asia, these names offer useful reference points. They also show why comparing every functional drink as though it does the same job can be misleading.
Four functional drink trends shaping 2026
1. Choosing by benefit and occasion
The shelf is expanding beyond a single promise of more energy. NielsenIQ’s June 2026 perspective highlights demand across energy, hydration, gut health and immunity, alongside interest in focus, mood, recovery and alcohol-free occasions. 8
That opens up a more personal way to choose: a drink for the activity you are doing or the routine you want to support. It does not mean everyone needs a different supplement for every hour.
2. Taste and value still matter
A wellness claim may make you curious. Taste, price and trust help determine whether you buy again.
FMI’s Power of Beverage 2026 report found that US shoppers associated beverage value with low price, taste, trusted quality and a trusted brand. Its survey covered 2,003 US adult grocery shoppers. 9
A practical comparison is cost per serving, including the amount you actually use. A large tub, a small bottle and a stick pack can have very different serving economics.
3. Social discovery meets label checking
FMI reported that 45% of Gen Z respondents found a beverage more appealing after learning about it from a creator or influencer, with millennials responding at a similar level. 9
Discovery is easy.
Deciding takes a little more attention.
A creator can show you a flavour or a routine; the label tells you the ingredients, quantities and directions.
Evidence should relate to the actual formula and amount, rather than just an ingredient with an impressive name.
4. Convenience alongside transparency
Ready-to-drink bottles, cans and mix-in powders serve different routines. A can is immediately ready; a stick pack is portable but needs mixing.
NielsenIQ identifies transparency, convenience and performance as important consumer expectations. 8
The appealing format is the one that works in real life—and makes it easy to understand what you are consuming.
Energy drinks vs sports drinks vs wellness drinks
These categories can overlap, but their usual purposes differ.
Alertness or an active day
Energy drinks
Complete formula, active ingredient quantities, sugar and directions
Fluids and exercise fuel
Sports drinks
Electrolytes, carbohydrate and serving size
Digestive support
Probiotic drinks
Named strains, stated amounts and storage instructions
Protein intake
Protein drinks
Protein per serving, source and allergens
Focus or everyday balance
Targeted wellness drinks
Ingredient amounts, product-specific evidence and suitability
Healthy-looking skin
Beauty-from-within drinks
Collagen peptides or nutrients intended to support collagen production
An energy drink is not automatically a sports hydration drink. A plant-based collagen-support drink is not automatically a serving of conventional collagen peptides. Start with the purpose, then read the formula.
How to choose a functional drink for your routine
Before buying, ask yourself:
What is my main goal? Choose a specific purpose rather than a long list of promises.
What is in a full serving? Check the complete label, quantities, sugar, allergens and directions.
What supports the claim? Look for evidence relevant to the product, not only its marketing language.
Does it fit my day and budget? Consider taste, preparation and cost per serving.
Is it suitable for me? Follow the local label and seek qualified advice if you take medication or have a health condition.
A drink can be part of a routine. Food, sleep, movement and recovery still shape how that routine feels.

Functional drinks FAQ
What is a functional beverage?
A functional beverage is a drink marketed to offer a benefit beyond taste and refreshment, such as energy, hydration, protein intake or digestive support. Its usefulness depends on its ingredients, amounts and evidence.
Are functional drinks and energy drinks the same?
No. Energy drinks are one part of the functional beverage category. Sports drinks, probiotic drinks and some protein or targeted wellness drinks belong to other parts of it.
Why are functional drinks popular with Gen Z and millennials?
Recent US research shows high consumption among both groups. Benefit-focused choices, convenient formats and digital discovery help explain the trend, although preferences vary by person and market. 1, 8, 9
What are some well-known functional drink brands?
Examples include Red Bull and Monster in energy, Gatorade and Pocari Sweat in hydration, Yakult in probiotic drinks, and CELSIUS in fitness-oriented energy. Their sales measures and geographic reach differ, so this is not a global sales ranking.
Are functional drinks automatically healthier than ordinary drinks?
No. A functional claim does not establish overall nutritional quality or effectiveness. Compare the full formula, serving size, sugar and evidence with your actual needs.
What should I check when buying functional drinks in Singapore?
Read the label supplied for Singapore, including ingredients, quantities, allergens and serving directions. Overseas product pages can describe different formulas or pack sizes. Check local availability and price before ordering.
