How Flavoured Hydration Tablets Help You Drink More Water

Most of us start the day meaning to drink more water and get to 4pm with the same bottle barely touched. Plain water is the best everyday drink there is, but plenty of people find it hard to drink enough of it. Adding flavour is one of the simplest ways to change that.

How much should you drink?

The NHS Eatwell Guide suggests 6 to 8 glasses of fluid a day for most adults. The European Food Safety Authority puts total water needs, from food and drink combined, at about 2 litres a day for women and 2.5 litres for men. Water, lower-fat milk and sugar-free drinks, including tea and coffee, all count. You'll need more on hot days, when you exercise and when you travel.

The easiest check is the colour of your pee. Pale yellow means you're drinking enough. Dark yellow and strong-smelling means you need more. Thirst, tiredness and headaches are among the early signs of dehydration, and research has linked even mild dehydration to lower mood and poorer concentration in healthy adults.

Why plain water is hard to keep up with

• You forget, especially when you're busy
• It gets boring by the third or fourth glass
• Coffee, tea or a fizzy drink is easier to reach for
• You don't feel thirsty until you're already a bit behind

Why flavour helps

Taste affects how much people drink. A drink you enjoy is one you keep going back to, whether you're at a desk, on a train or at the gym.

Flavoured hydration tablets give you that without the sugar of squash or fizzy drinks. You drop two into water, they fizz and dissolve, and you've got a lightly flavoured drink with added minerals.

HIRO's three flavours

HIRO was voted Best Tasting Electrolyte Tablets by BBC Good Food in 2025 and Best Hydration Flavours by The Independent in 2026. HIRO electrolyte tablets come in three flavours, all designed to taste light rather than salty or sweet:

• Lemon & Elderflower: bright and floral.
• Ginger & Lemongrass: warmer and more botanical, a good pick if you don't like sweet drinks.
• Watermelon: the fruitiest of the three.

Rotating flavours stops it feeling like a chore. The Multi-Flavour Triple Pack gives you a tube of each.

A serving is two tablets in about 300ml of water. It contains 300mg potassium, 180mg chloride, 116mg sodium and 65mg magnesium, plus zinc and manganese, with 5g carbohydrate and 20 kcal. It's sweetened with sucralose and is vegan. Magnesium contributes to electrolyte balance and the reduction of tiredness and fatigue. For more on why HIRO leads with potassium, read our guide to high-potassium electrolyte tablets.

Making it a habit

• Tie it to something you already do. Your first drink of the morning, the post-lunch slump or straight after the gym.
• Keep a tube where you'll use it. Desk drawer, gym bag, car or travel bag.
• Use a bottle you like. A 500ml bottle makes it easy to see how much you've had.
• Swap one drink. Replace an afternoon fizzy drink or a third coffee with a flavoured water.
• Keep drinking plain water too. Electrolyte tablets work alongside it. Stick to the serving on the label and make the rest of your fluid water.

Who should check first

If you have a kidney or heart condition, take medicines that affect potassium (including some blood pressure medicines), are pregnant or breastfeeding, or are an older adult, speak to your GP or pharmacist before using electrolyte products regularly. HIRO isn't recommended for anyone under 18.

Summary

If you find plain water hard to drink enough of, flavour is a simple fix. A flavoured electrolyte tablet makes water more appealing without the sugar of squash or fizzy drinks, and a tube is easy to keep with you. Every HIRO order comes with a 60-day money-back guarantee, so you can find the flavour you like.

Frequently asked questions

Do flavoured drinks count towards my daily fluid?

Yes. The NHS counts water, lower-fat milk and sugar-free drinks, including tea and coffee, towards your 6 to 8 glasses. A flavoured electrolyte drink counts too.

Are flavoured hydration tablets better than squash?

They do a different job. Squash adds flavour, and regular squash adds sugar. An electrolyte tablet adds flavour plus minerals. A HIRO serving has 5g carbohydrate and 20 kcal.

How many HIRO servings can I have a day?

Stick to the serving on the label: two tablets in about 300ml of water. Make the rest of your fluid plain water.

Which flavour should I start with?

If you're not sure, the Multi-Flavour Triple Pack gives you one tube of each, so you can find your favourite before buying a bigger pack.
