Our Best-Selling Healthy Drinks To Beat the Heat This Summer

When the temperature climbs, most people reach for the same thing: a can of something fizzy, full of sugar, and gone in three minutes. It quenches your thirst for about half an hour before the sugar crash kicks in and you're reaching for another.

There's a better way to stay cool. The healthy drinks worth knowing about right now go well beyond water with a slice of lemon — from naturally fermented kombucha and pure coconut water to protein-packed hydration and cold-pressed immunity shots. All from independent producers, all made with real ingredients, and all available by the case at warehouse-direct prices.

What makes a drink "healthy" in the heat?

When it's hot, your body loses water and energy faster than usual. A good summer drink should do more than just quench your thirst — it should actually put something useful back in. That might mean natural electrolytes from coconut water, live cultures from fermented kombucha, a hit of protein after exercise, or just real ingredients instead of artificial sweeteners and flavourings.

Every brand in this list has one thing in common: a short ingredient list with nothing to hide. If you can read every ingredient on the label and understand what it is, you're probably drinking the right thing.

1. Holos — Organic Kombucha Brewed for Good

If you only try one new drink this summer, make it this one.

Holos was founded in 2018 by five friends — Naomi, Megan, Christine, Tom and Joseph — after a life-changing encounter in Cambodia. While volunteering, Naomi and Megan witnessed first-hand the impact that meaningful work could have on people who'd experienced exploitation. Back in the UK, they set out to build a business with genuine social purpose — and landed on kombucha.

Every bottle is handcrafted in their microbrewery in the hills of West Sussex using traditional fermentation methods, organic loose-leaf teas, and a living SCOBY culture. No shortcuts, no pasteurisation, no artificial carbonation. What you get is chilled, lightly sparkling, gut-friendly fermented tea that's genuinely alive with beneficial cultures.

The flavours are what set Holos apart. Citra Hops is crisp and citrusy — it won a 3-star Great Taste Award in a blind taste test of the UK's leading kombuchas. Ginger & Hibiscus is a punchy, full-bodied crowd-pleaser that pairs brilliantly with food. Raspberry & Elderflower is floral and juicy. And Basil & Mint tastes like a virgin mojito — genuinely refreshing straight from the fridge on a hot afternoon.

But the real story is the mission. "Holos" means wholeness in Greek, and the business exists to provide meaningful employment and support for survivors of modern slavery and human trafficking in the UK. They partner with anti-trafficking charities, run paid work placements for survivors at the brewery, and set aside 25% of their shares for The Holos Foundation. In 2024 alone, they provided over 500 hours of paid work for six people rebuilding their lives from trauma and exploitation.

When you buy a case of Holos, you're getting genuinely brilliant kombucha and supporting something that genuinely matters.

Holos Organic Kombucha — Cases of 12 from £37. Four flavours, all organic, all unpasteurised, all alive.

2. Coconaut — Pure Vietnamese Coconut Water

When it's properly hot, nothing rehydrates quite like coconut water. It's naturally rich in potassium, magnesium, and electrolytes — exactly what your body loses through sweat — and the best versions contain nothing but the water from young coconuts: no added sugar, no concentrates, no water padding it out.

Coconaut sources 100% pure coconut water from young Vietnamese coconuts — sweeter, lighter, and more nutrient-dense than mature coconut water. Available as pure still, sparkling, and infused with pineapple or watermelon. One of the cleanest coconut waters on the market, and it tastes like it.

A case in the fridge is the smartest summer move you'll make.

3. Vieve — Protein Water That Actually Refreshes

Protein water used to taste like someone had dissolved a scoop of powder into a bottle of water and hoped for the best. Vieve changed that. Each bottle delivers 20g of protein, zero sugar, and just 85 calories — and it genuinely tastes like flavoured water, not like a protein shake that's been watered down.

Vieve comes in five natural flavours including watermelon and strawberry & rhubarb. Drink it cold after a run, a gym session, or even just a long walk in the heat. It's one of the most refreshing ways to get protein without feeling like you're choking down a supplement.

4. Plenish — Cold-Pressed Ginger Immunity Shots

A 60ml shot of cold-pressed ginger, lemon, and apple cider vinegar first thing in the morning is one of the best rituals for a hot summer day. It wakes you up, supports your immune system, and gives your digestion a kickstart — all without the caffeine crash.

Plenish was founded by Kara Rosen, who moved from New York to London in 2012 and couldn't find the cold-pressed juices that had transformed her health. A decade later, Plenish is sold in thousands of stores across the UK. The Ginger Immunity Shot is their bestseller — each 60ml dose delivers 100% of your recommended daily vitamin C from acerola cherry. No flavourings, no preservatives, no additives. Just organic, cold-pressed produce. The new 420ml dosing bottles give you a full week of shots in one bottle.

5. Glug! — 100% Natural Tropical Juice

Sometimes you just want something fruity, cold, and uncomplicated. No functional claims, no added vitamins, no wellness angle — just pure fruit juice made from real tropical fruit, pressed at source with nothing added.

Glug! is a family-run tropical juice brand making 100% natural fruit drinks — mango, passionfruit, watermelon — picked and pressed at source in Asia. No concentrates, no added sugar, no preservatives. Just fruit in a bottle. Pour it over ice on a hot day and it's one of the most satisfying drinks going.

6. Spraga — Naturally Fermented Kombucha

If Holos is the craft-brewery approach to kombucha, Spraga is the bold, colourful challenger. A Ukrainian brand that recently launched in the UK with a mission to prove that healthy drinks don't have to be boring.

Spraga is made using organic tea, organic cane sugar, and a living SCOBY culture — naturally fermented, unpasteurised, and completely free from sweeteners, concentrates, and preservatives. Four flavours: Original (clean and gently tart), Ginger & Lemon (a spicy lift), Pomegranate (fruity depth), and Apple & Pear (subtly sweet). Every can is packed with live probiotics.

Currently 20% off at FODA Warehouse — cases of 12 from £28.32.

7. Brite — Nootropic Drinks for Hot-Day Focus

Heat and concentration don't mix well. When it's 30 degrees and you're trying to work, another coffee is the last thing you need — it'll dehydrate you and leave you jittery. A nootropic drink is a smarter alternative: calm, sustained focus from natural ingredients without the crash.

Brite was created by Andrius and Simas, two founders who spent years relying on coffee and got fed up with the jitters. Each can combines 100mg of natural caffeine with 100mg of L-theanine (a relaxant) and 100mg of ashwagandha (an adaptogen), plus organic matcha, guarana, and guayusa. Lightly sparkling, zero added sugar, nothing artificial. Available in Lemon Lime and Raspberry & Mint — both taste sharp and clean straight from the fridge.

How to build your summer drinks rotation

You don't need all seven in the fridge at once. A good starting point: pick one for morning (Plenish ginger shot), one for afternoon (Holos kombucha or Coconaut), and one for active days (Vieve protein water). Rotate and experiment from there.

Buying by the case brings the per-unit cost down significantly, and means you're not running out halfway through the week.
