If you're like me, you've probably felt the struggle of sifting through endless advice on how to boost your energy. Drink coffee, cut carbs, eat more carbs, get more rest, move more —honestly, it’s a noisy world out there. But here’s the thing: there’s no one-size-fits-all solution to feeling good and being energised.
My mission at Lifestyle Rebelz is to help you tune out the noise and tune in to what works for ‘YOU’!
For someone who’s never been into coffee (yup, I said it—just can’t stand the taste), grabbing a quick caffeine fix has never been an option.
And as an accredited health coach, nutrition isn’t just a buzzword; it’s ‘one’ of the foundations of my energy remedy programmes. So, finding healthy, sustainable ways to power up when I need it—without the sugar-crash trap or relying on mystery ingredients that sound more at home in a lab than in my drink.
This is where my obsession with ‘functional drinks’ kicks in. I’ve uncovered some absolute gems—tasty, clean, and that support my body naturally, without drowning in sugar or sketchy chemicals. And when it comes to energy drinks, I’m all about finding something healthy, effective and delicious—because if it doesn’t taste good, you can count me out.
Of course, I’ve got to say—while I love these drinks, I’ll never claim that any drink or supplement is the magic fix for all-day energy.
Let’s be real: we’re not built to have level-10 energy around the clock. Our bodies work in cycles, and we’re meant to experience natural dips in energy that signal it's time to recharge.
One of the key approaches I coach is helping people tune into their rhythms—learning when to rest and recharge and when to tap into those high-energy moments to take action and get things done.
Mastering your energy is like piecing together a puzzle with many lifestyle factors at play. The first step? Identifying your personal energy drains. My blog, Unlock Better Energy, explores how tuning into your own intuition reveals what works best for you—because energy-boosting isn’t one-size-fits-all. And don’t miss 5 Not-So-Obvious Things That Could Be Draining Your Energy to uncover those hidden energy hijackers that may be holding you back.
While there are plenty of ways to boost your energy without drinking anything, sometimes life throws curveballs. And when the demands are real, we all need that quick, reliable pick-me-up.
If diving into the details isn’t your thing, no worries—this blog might spark a few ideas to get you started, and I’ve done the research for you.
Every drink I mention here is one I genuinely love, but don’t just take my word for it. My approach is all about finding YOUR fit. My mantra? “Stay Curious and Find What Works For YOU”.
What are functional drinks?
Before I dive into my top fave functional drink brands, let’s take a second to talk about what functional drinks actually are. Functional drinks are beverages that go beyond just quenching your thirst. They’re packed with ingredients that support specific health goals—whether that’s energy, focus, hydration, relaxation or gut health.
Think of them as a sneaky way to get more benefits in your day with zero hassle. And as a fan of quality supplementation (because, yes, I’ve got knowledge and experience with nutritional science), I always look for drinks with solid, research-backed ingredients, minimal additives, and ones that actually do what they claim. I’m here for real results, not marketing fluff.
**Disclaimer:** As the poet Lucretius wisely said, "One man's food is another man's poison." So, while this list highlights the products that work for me, you might need to experiment to find what works best for *you*. Consider this a starting point on your journey to finding your own go-to energy boosters!
So, without further ado, let’s get into my choice of the three best natural energy drinks available in the UK. The three functional drinks that I absolutely love right now for a quick energy boost. Each one checks all the boxes: great taste, quality ingredients, and, most importantly—they work (for me). Let’s dive in!
My three favourite liquid pick-me-ups
Grass & Co’s ‘Liquid Power’
If you’re looking for a clean, natural energy boost, Grass & Co.’s ‘Liquid Power’ has quickly become one of my go-to options when I need that extra kick. Whether starting my day off on the right foot or powering through an afternoon slump when a mid-day power nap isn't an option, this drink has my back. And trust me, I don’t say that lightly!
Active ingredients & what they do
Liquid Power is packed with some stellar, science-backed ingredients designed to keep your energy steady without the jitters or crashes:
Here’s a breakdown of how each of these ingredients supports energy and vitality:
Shiitake extract
Shiitake mushrooms have been traditionally used to support energy and overall vitality within traditional Chinese and Ayurvedic medicines. They are rich in antioxidants, vitamins, and minerals and contain a bioactive compound called lentinan, a type of beta-glucan polysaccharide. It has been shown to help maintain healthy immune function and provide anti-inflammatory and antioxidant effects. These properties help the body better adapt to stress (a key feature of adaptogens), helping prevent energy depletion over time. [1]
Guarana seed extract
Guarana is a powerful, natural source of caffeine—more concentrated than coffee beans. It stimulates the central nervous system, increasing alertness and focus while fighting fatigue. Guarana is also slowly absorbed, which provides a longer-lasting energy boost without the typical crash associated with synthetic caffeine.[2]
Natural caffeine coffee extract
This is a potent source of caffeine, designed to give a quick, effective energy boost. Natural caffeine helps increase mental clarity, concentration, and alertness while fighting off feelings of tiredness. Natural caffeine extract provides smoother energy, less acidity, a more precise caffeine count and fewer jitters than regular brewed coffee.
Vitamin B6
Vitamin B6 plays a crucial role in converting food into energy. It helps your body metabolise carbohydrates and fats and is essential for proper brain function. It also supports neurotransmitter production, which affects mood and energy levels.
Vitamin B12
Vitamin B12 is another crucial vitamin for energy production. It supports red blood cell formation, which helps deliver oxygen throughout the body. Low B12 levels can lead to fatigue, making it vital for maintaining energy and vitality.
Sugar & caffeine content
Let’s talk sugar— ‘Power’ isn’t too bad, with around 6g of sugar per 250ml serving. Relatively low, especially when compared to your usual soft drink (hello, Coca-Cola with its 27g in the same amount!). But if you're like me and enjoy one of these in the morning and another cheeky one in the afternoon, that sugar adds up fast. Plus, with a solid 174mg of caffeine per can, it’s wise to watch how many you down to avoid sugar and caffeine overload. Balance is the key to so much in life!
Taste
As for the taste—honestly, I’m into it! It’s a smooth, refreshing blend with a slight herbal and ginger kick, but it’s not overpowering. I’d describe it as earthy with a hint of natural sweetness that’s easy to sip. The carbonated water gives it that “bubbly pick-me-up” feel, as the label describes. It actually does what it says on the tin, which is essential to become part of my go-to product choices. Plus, It doesn’t have the artificial taste many energy drinks have, which is a huge plus in my book.
How it works for me
Grass & Co.’s *Power* provides a solid kickstart in the morning when I need that boost to hit the ground running. On days when I have a lot of work or can’t squeeze in my usual afternoon power nap (which, BTW, is a game-changer for me), this drink is the perfect backup. It helps me stay energised and focused without feeling wired or on edge.
Plus, it tastes fantastic. I’m all about enjoying things that satisfy your taste buds while fuelling your health. I do a happy dance when I discover food or drinks that tick both boxes.
Final thoughts
Overall, I’m a big fan of this functional drink. It ticks all the boxes—natural ingredients, enjoyable taste, and a legit energy boost. Just be mindful of the sugar content if you have more than one or two a day. It’s an ideal way to stay productive when I need a little extra push, whether first thing in the morning or as an afternoon pick-me-up.
2. Perfect Ted Healthy Energy
If you're after a clean, natural energy boost that doesn’t sacrifice taste, let me introduce you to ‘Perfect Ted ‘s Healthy Energy’. It's quickly climbed the ranks as one of my all-time favourite natural energy drinks. Whether I need a gentle pick-me-up to get the cogs turning in the morning or a refreshing sip to beat the mid-afternoon slump, this drink has me covered—without the jittery crash many other energy drinks cause.
Available in 4 flavours:
Apple and Rasberry
Juicy Peach
Pineapple & Yuzu
Peach & Ginger
While Apple & Raspberry is my personal favourite, with such a tempting variety, you’re bound to find at least one that hits the spot!
Active ingredients & what they do
One of the things I love most about PerfectTed is the minimal number of ingredients. I’m all about quality over quantity—I want to know exactly what I’m putting into my body and, more importantly, be able to pronounce it! With just a handful of simple, natural ingredients, this drink proves that less is definitely more when it comes to fuelling your body.
PerfectTed’s blend is all about clean, natural energy, combining the power of matcha with a fresh, fruity twist. Here’s what’s inside and why it works:
Organic Matcha green tea
Matcha is the star of the show here. Catechins, found in matcha, are linked to cardiovascular health by reducing oxidative stress, lowering cholesterol, and improving blood pressure [3]. Packed with antioxidants and naturally occurring caffeine, matcha provides a steady, sustained energy boost that sharpens your focus without spiking your heart rate.
Unlike coffee, matcha contains L-theanine, an amino acid that promotes relaxation and calm, meaning you get all the mental clarity without feeling wired.
Green tea leaf extract
This powerhouse ingredient is packed with antioxidants, particularly catechins, which help combat oxidative stress and support overall health. Not only does it provide a gentle, steady release of energy thanks to its natural caffeine, but studies also suggest it boosts metabolism, increasing calorie expenditure and fat burning. Plus, it’s known for its calming effects due to the presence of L-theanine, helping to keep you focused and energised without the jitters.
B vitamins for energy & vitality
PerfectTed is packed with a complete range of B vitamins, including B1, B2, B3, B5, B6, B7, B9, and B12, each playing a crucial role in supporting your body’s energy production. These vitamins help convert your food into usable energy, keeping fatigue at bay. They also support brain function, mood regulation, and overall metabolic health. B12, in particular, helps with red blood cell formation, ensuring oxygen is efficiently delivered throughout your body. These B vitamins provide a natural energy boost, helping you stay alert and energised throughout the day.
Apple & raspberry juice
These juices don’t just add a sweet, fruity flavour—they also bring natural sugars that give an instant lift. Unlike processed sugars, natural fruit sugars are slowly absorbed, giving you a more even, long-lasting fuel source. Plus, they’re loaded with vitamins that give your immune system a little extra love. Who doesn’t love a drink that does double duty?
Sugar & caffeine content
Speaking of sugars, PerfectTed keeps it pretty clean. There’s about 5.3g of natural sugar per 250ml can—not too shabby compared to the sugar bombs that pass for energy drinks on most shelves. But remember, natural sugars still count, so if you’re throwing back a couple of these daily, keep an eye on your total intake. With 80mg of caffeine per can (equivalent to a cup of coffee), it’s wise to monitor how many you have to avoid overloading with sugar and caffeine. Remember the balance!
Taste
Now, let’s talk about taste. Honestly, I’m obsessed. The apple-raspberry combo is refreshingly light and fruity without being overly sweet. The matcha has subtle earthiness, but it blends so smoothly with the fruit that even if you’re not a die-hard green tea fan, you’ll still like it. Plus, it’s not fizzy despite being made with sparkling water, so you can sip away without feeling bloated or gassy. It’s the kind of drink you can enjoy mid-afternoon without that overwhelming "energy drink" aftertaste—just clean, fruity goodness with a hint of sophistication.
How it works for me
When I need a light yet effective energy boost, this is my go-to. Whether it's those mornings when I need to be sharp or afternoons that demand focus, it delivers a clear, steady lift—minus the crash. The taste? Pure treat, not a task. And knowing it’s loaded with natural, good-for-you ingredients? Total win in my book.
Final thoughts
Overall, PerfectTed Apple Raspberry Matcha Green Tea is a game-changer for me as a non-coffee drinker. It’s got everything I want in a drink—natural energy, great taste, and clean ingredients. Keep an eye on how many you have if you’re mindful of your sugar intake. It’s a no-brainer when I need a little boost that’s both delicious and good for me.
3. Amino Man’s L-Amine Iced Tea Amino Drink
Looking for a refreshing, nootropic boost that sharpens your focus and keeps your energy steady? Amino Man’s L-Amine Iced Tea Amino Drink is a must-try. Whether I’m gearing up for a brain-taxing morning or cruising through an afternoon of deep work, this drink keeps me sharp without the crash that comes with sugar-loaded, caffeine-heavy options.

Active ingredients & what they do
L-Amine Iced Tea blends natural nootropics, amino acids, and essential vitamins to support mental clarity and physical stamina. While some ingredients may not be from a natural source due to the challenge of maintaining potency, every element is designed with quality in mind by nutritionists to athletes—no fillers, just quality active ingredients.
Here’s a breakdown of the key players:
L-Tyrosine: This amino acid supports dopamine and norepinephrine production, enhancing mood, focus, and cognitive function—especially in stressful situations.
Green Tea Extract: Rich in antioxidants and a natural source of caffeine, it delivers steady energy and enhanced focus without the jitters. L-theanine adds a calming effect.
L-Theanine: A perfect partner to caffeine, it smooths out the buzz, promoting relaxation and focus without overstimulation.
Panax Ginseng Extract: studies suggest this adaptogen combats fatigue and boosts physical and mental endurance, keeping your energy steady. [4]
5-HTP (Griffonia Seed Extract): As a serotonin precursor, it supports mood, reduces stress, and enhances cognitive function.
Choline Bitartrate: Essential for brain health, it improves memory, focus, and mental clarity—perfect for cognitive performance.
Magnesium Citrate: A key player in energy production, magnesium helps convert food into energy, reduces fatigue, and enhances muscle function and mental clarity.
Sugar & caffeine content
Here’s the best part: L-Amine Iced Tea is sugar-free. Naturally sweetened with a hint of stevia (derived from the Stevia rebaudiana plant), it avoids the sugar crash while delivering a light, pleasant sweetness. Stevia helps maintain balanced blood sugar levels and has antioxidant properties—talk about a healthier alternative! [5]
The caffeine content is modest at 15mg per 440ml can—perfect for a cheeky late-afternoon pick-me-up without messing with your sleep. This drink keeps your blood sugar stable and your body balanced.
Taste
I was sceptical about a sugar-free, nootropic drink, but it’s surprisingly refreshing! With a crisp flavour, very, very slight tea undertone and a touch of lemon, it’s clean, light, and easy to sip—no weird aftertaste or overpowering sweetness. Perfect for summer days or a quick break between tasks.
How it works for me
‘L-Amine Iced Tea’ has become my go-to on heavy workload days or when I need to be in top mental form. It helps me stay clear-headed and focused without the crashes or jitters of sugary, high-caffeine drinks. Plus, knowing it’s packed with good-for-you ingredients and low in caffeine means I can have it later in the day without disrupting my sleep—a total win.
Final thoughts
Amino Man’s ‘L-Amine Iced Tea’ checks all the boxes—high-quality ingredients, no sugar, great taste, and a lasting energy boost. Expertly formulated by Matt Lovell, nutritionist to athletes, it’s a product I trust.

Whether you’re after mental clarity, a caffeine boost, or all-around performance enhancement, this drink has you covered. It’s now a permanent fixture in my fridge, fuelling me for busy days and deep focus sessions.
In conclusion, functional drinks can be a great addition to your energy-boosting toolkit, offering natural ingredients that enhance focus, stamina, and mental clarity. However, it’s essential to stay curious and experiment—what works for me may not be the magic bullet for you.
Reclaiming and maintaining energy takes a holistic approach—nutrition, rest, movement, stress management—all the good stuff. Pay attention to what works across every area of your life; that’s how you’ll find your unique energy remedy.
While natural energy drinks can provide a helpful pick-me-up, they shouldn’t be relied on as the sole solution. Balance is everything—use these drinks to support your overall lifestyle, not as a quick fix in isolation.
