A Quick Guide to Functional Drinks Sans Drinks

Did you know that a major recent review (2024) found magnesium to be one of the top six nutrients Australians consistently fail to get enough of? Alongside calcium, vitamin D, fibre, folate and omega‑3s, magnesium appeared at the top of the list for nutrient inadequacy across multiple demographic groups. 

That matters, because magnesium is involved in hundreds of biochemical reactions, powering energy production, regulating mood, supporting muscle and nerve function and helping the body recover from stress. When intake is low, symptoms like fatigue, poor sleep and low mood can follow. 

It’s not just magnesium. Many people also fall short when it comes to nutrients that functional ingredients like zinc, folate, or adaptogenic botanicals can deliver. Functional drinks exist to bridge these gaps. They’re made using ingredients that have been researched for specific benefits: adaptogens that help the body adapt to stress, nootropics that support cognitive clarity, calming botanicals, and essential minerals.

These drinks are purpose-built to support how we actually live: clearer energy in the morning, steady focus in the afternoon, calmer evenings and restful nights. If the body is missing something, the drink is designed to deliver it.

In the sections that follow we’ll dive into what ingredients really count, how they support different times of day and needs, and how to recognise a drink that’s actually doing something for you, not just filling space in the fridge.

Why Functional Drinks Are Trending

There is a growing demand in Australia for drinks that deliver functional benefits along with refreshment.

  • In 2023, 58 per cent of soft drink spending in Australia was on healthier options like juices and mineral water. A clear shift away from traditional fizzy drinks.

  • Mintel reports that 36 per cent of Australians are willing to pay more for food or drinks with functional health claims, such as immune support, energy or stress relief.

  • Functional beverages account for 10 per cent of all new food and drink launches across the Asia‑Pacific and Australia holds the fifth‑largest share of products with functional claims.

From adaptogens to added vitamins, consumers are increasingly choosing drinks that do more than just taste good. They want benefits that align with their wellness goals.

Key Functional Ingredients to Know

As functional drinks become more mainstream, understanding what goes into them and why helps consumers make smarter choices. Here are the most common ingredient types found in functional beverages today:

Adaptogens

Examples: Ashwagandha, Holy Basil (Tulsi), Rhodiola Rosea

Adaptogens are natural compounds that help the body adapt to physical and emotional stress. By supporting the adrenal system, they may help regulate cortisol levels and promote a sense of calm. Drinks with adaptogens are often marketed for stress relief, balance and recovery from daily pressures.

Nootropics

Examples: L-theanine, Lion’s Mane Mushroom, Bacopa Monnieri

Nootropics are cognitive enhancers that may support memory, concentration and mental clarity. For instance, L-theanine, found in green tea, is known for promoting focus without jitters, making it a popular addition to drinks designed for productivity, study, or work.

Prebiotics & Gut-Friendly Additions

Examples: Inulin and Chicory Root Fibre

Gut health plays a crucial role in immunity, energy and even mood. Prebiotics feed beneficial gut bacteria and support digestion. Functional drinks often include these ingredients to help maintain microbiome balance and support overall well-being from the inside out.

Botanicals & Herbal Blends

Examples: Chamomile, Lavender, Lemon Balm, Ginseng

Herbal ingredients are used to target specific mood or sleep benefits. Calming herbs like chamomile and lemon balm are common in beverages meant for relaxation or sleep support, while energising herbs like ginseng or ginger are included for their uplifting or invigorating effects.

Minerals

Examples: Magnesium, Zinc, Potassium

Minerals are essential for physical and mental function. Magnesium helps with muscle recovery and sleep, while zinc plays a role in immunity and mood regulation. Many functional drinks now include bioavailable forms of these minerals to support daily wellness needs, especially for active lifestyles or stressful routines.

How Functional Drinks Support Daily Life

Morning motivation

Start your day with drinks that gently boost your energy and help you feel focused. Ideal if you’re cutting back on coffee but still want to feel switched on.

Staying focused through the day

Busy days call for ingredients that support mental clarity and concentration. These drinks help keep you alert without the caffeine crash.

Easing into the evening

Evenings are easier with blends that help you switch off. Great for relaxing after work, errands or anything in between.

Getting better sleep

Struggle to settle at night? Drinks with calming herbs or minerals can support a smoother wind-down and deeper rest.

Everyday support for gut and mood

Sip your way to better gut health and mood balance with drinks that contain prebiotics or mood-friendly botanicals. Consistency here is key.

What to Look for When Choosing a Functional Drink

It has to taste good

Let’s be honest. If it doesn’t taste great, you won’t go back for a second sip. A functional drink should do what it says, but flavour still matters. You want something you actually enjoy drinking, not something you’re forcing down because it’s “good for you.”

Ingredients should make sense, not just sound fancy

Skip the fluff. Look for drinks that use ingredients with a real purpose and in amounts that matter. If there’s ashwagandha or magnesium or ginseng in it, you should know why it’s there and what it’s supposed to help with. The best brands are upfront and clear about what they use and why.

Watch the sugar 

Some drinks load up on sugar or artificial sweeteners to cover the taste of functional ingredients. But a clean label with low or no added sugar? That’s a win. Your body doesn’t need the crash that comes with hidden sweeteners.

Check the brand’s vibe  

Some brands are just trend-chasing. Others are doing the work. Look for ones that share their process, talk about the science behind their blends, or work with actual nutritionists. If a brand seems thoughtful and consistent, chances are the drink is too.

Pick something that fits your lifestyle

Are you after a boost in the morning, focus in the afternoon, or something calming in the evening? The best drink for you depends on when and why you’re having it. It’s not one-size-fits-all, and that’s a good thing.

Bonus points if it’s planet-friendly

If it comes in sustainable packaging or supports responsible sourcing, that’s a nice extra. A drink that’s good for you and easier on the planet? Even better.
