If you’ve resolved to up your fitness game in 2026, replace the salts and minerals lost through sweat with my pick of the best electrolyte drinks.

Much like pre-workout powders, the best electrolyte drinks can play a useful supportive role in our fitness regimes. Electrolyte drinks help replenish the naturally occurring salts and minerals that help balance our bodies’ fluids. Our electrolytes get depleted through exercise, most notably through sweating. The best electrolyte drinks often also contain carbohydrates and other nutrients to help you stay hydrated and to improve recovery.

But not all electrolyte drinks are created equal. It pays to consider the amount of the electrolytes potassium, chloride and particularly sodium in each drink, which help with preventing cramping, aiding muscle contraction and supporting hydration respectively.

If you’re not a heavy sweater, or need to reduce your intake of sodium for health reasons, you might want an electrolyte drink with lower sodium levels (say, less than 250mg per serving).

Why you can trust Men’s Fitness

We spend hours testing every product or service we review, so you can be sure you’re buying the best. Our team of fitness kit reviewers includes experienced product testers and fitness writers – as well as the core MF team – who know exactly what sets the best products apart from the rest. This selection of the best electrolyte drinks was tested by nutritionist Rob Hobson and sports and fitness journalist Laurence McJannet. Find out more about how we test.

Another trusted player in the sports nutrition market, High 5 is the go-to brand for many endurance runners, including many members of the Men’s Fitness team. It’s a good choice if you’re training for extended periods as one tablet is enough for a 750ml water bottle. They may be free of sugar, but these tabs are full of flavor – I tried the citrus flavor, which offered a nice balance of sweetness and tanginess.

4. Skratch Labs Hydration Sport Drink Mix

There are also an impressive eight flavors available, with each one providing a nice, hydrating option at the end of a tough workout.

Ideal for larger bottles and longer sessions, GU tablets will see you through intense or prolonged training. I found the tablet combined well in water and didn’t require any additional shaking to combine. There’s a good amount of electrolytes in the mix, especially sodium, and I enjoyed the punchy flavors, but they may be a bit too intense for some people.

6. Good Salt

Best electrolyte drink for functional hydration

Men’s Fitness verdict

These fresh tasting electrolyte sachets may be a little light in sodium, but they are well balanced with other active ingredients for optimal hydration throughout the day.
Pros
  • Six pleasant, fresh flavors
  • Targeted active ingredients
  • Less that £1 a serving if you subscribe
Cons
  • Sodium varies from 75mg to 400mg

Specifications Product 1
Serving size 1 sachet in 500ml water

Price per serving £1.15 or £1 by subscription
Flavors Lemon and Lime / Raspberry Lemonade (Focus); Peach / Lemonade (Chill); Strawberry Watermelon / Tropical Punch (Move)

Good Salt makes targeted electrolyte hydration drinks that are a little easier on the sodium than most, but don’t let that fool you. Its three varieties (Focus, Chill and Move) are each formulated for different states you might find yourself in throughout the day. Focus (lemon and lime / raspberry lemonade) has 100mg sodium per serving as well as l-theanine, zinc and B-vitamins to aid mental clarity; Chill (peach / lemonade) has 75mg sodium and chamomile to help you unwind; and Move (strawberry watermelon / tropical punch) has the most sodium – 400mg – as well as magnesium, taurine and citrulline malate to ‘help put back what your workout stole’. None of them have that unpleasant salty aftertaste so are quite pleasant to chug, they’re not overtly sweet, and they’re pretty decent value (particularly if you subscribe).

7. Punchy Hydration

Men’s Fitness verdict

These 330ml cans are made from natural ingredients, support all your hydration needs and have perfectly balanced flavors – great for hydrating in the go.
Pros
  • Well balanced flavors

  • Added vitamins and minerals
Cons
  • As with most cans, they’re pricier than tabs
  • Only two flavors

Specifications Product 1

Sodium per serving <330mg
Price per serving From £1.67 per can
Flavors Mango, blueberry

Punchy Hydration cans are lightly carbonated drinks made from natural ingredients with essential electrolytes, vitamins and minerals to boost hydration, aid muscle function and support your immune system. Available in mango and blueberry flavor, and in boxes of from 4 to 48 cans, they are deliciously refreshing with flavors that are indeed 'punchy', without being overpowering.

Buying in larger boxes will drop the price a bit – and subscribing to a regular deliver will give you a further 15% discount. Caffeine-free and low calories, they're a tasty alternative to electrolyte tabs and with their balanced favors are enjoyable as part of a regular hydration regime, with meals or as a perfect pick-me-up for the morning after the night before

8. Cadence Electrolyte Drink

Cadence electrolyte drink

Men's Fitness verdict

Performance-wise, these Cadence cans are the business. There are good amounts of key electrolytes and zero sugar or calories. They're pricey, though, even with the 20% subscription discount.
Pros
  • High level of sodium
  • Good balance of electrolytes
  • Subtle citrus taste
Cons
  • Expensive, even after discount
  • Slight salty aftertaste
  • Only one flavor

Specifications Product 1
Serving size 250ml

They're not cheap, but for those who are serious about their rehydration Cadence drinks are a sensible choice. These carbonated beverages are only beaten by SIS Go Hydro and Skratch Labs for sodium quantity, so are a great choice for heavy sweaters. There's key amounts of potassium and magnesium, too, and not a sniff of sugar or calories anywhere. They're also vegan-friendly and caffeine-free, with a pleasant, understated citrus flavor.

9. Hux Hydration Tablets

Product shot of Hux Hydration tablet tubes

Men's Fitness verdict

These sugar-free tablets feature high-quality ingredients and a sweet and tangy flavor. Dissolving quickly in water, they're ideal for general hydration, but sodium is too low for intense training.
Pros
  • Good mix of electrolytes and great taste
  • Suitable for general fitness and wellness
  • Reasonably priced
Cons
  • Low amounts of sodium may not be suitable for endurance sports or heavy sweaters
  • Limited flavors
  • Small serving size may limit its use in sports

Specifications Product 1
Serving size 2 tablets in 200ml water
Sodium per serving 116mg
Price per serving 70p
Flavors Lemon and elderflower, ginger and lemongrass, watermelon

Hux tablets are a good low-sodium option and are more suited to general hydration and wellness than intense workout sessions. They have a good mix of electrolytes as well as a pleasantly sweet and tangy flavor. The tablets also dissolved quickly in water. I reckon you could dilute them further if you needed more fluid and they would still retain the flavor.

10. Puresport Ultra Electrolyte

Best electrolyte drink for sodium content

Box of Puresport electrolyte powder

Men's Fitness verdict

Puresport adds a watermelon flavor to its lineup, in really handy 5.7g sachets – perfect for a pocket or race belt. You might want to dilute the salty taste a fair bit though.
Pros
  • More sodium than any other product on test
  • Not overly sweetened
  • Good balance of essential electrolytes
Cons
  • Very salty taste needs diluting
  • Only available online
Scroll to see more →
Specifications Product 1
Serving size 1 sachet in 450-900ml water
Sodium per serving 1,000mg
Price per serving £1.10
Flavors Watermelon salt, citrus salt, raspberry salt, orange lemonade

With 1,000mg per serving, Puresport's new watermelon salt flavor has more sodium than any other electrolyte product on this list – many by twice as much or more. That will explain the very salty aftertaste, which takes a bit of getting used to, though that's mitigated by diluting each sachet by 900ml (which the company still recommends).

At around £1.10 per serving, these Ultra Electrolyte sachets are better value than most, too. And I really like their slim size – perfect for sticking in race belts or vests, or running short pockets. With a decent balance of other electrolytes and three flavors to choose from, Puresport's offering is well worth looking at.

11. Ultima Replenisher Electrolyte Powder

Best electrolyte drink for everyday hydration

Product shot of Ultima Replenisher electrolyte powder

Men's Fitness verdict

This sugar-free blend mixes well and offers a decent combination of electrolytes, along with vitamin C. It's more suited to day-to-day hydration, rather than replenishing after extreme exercise.
Pros
  • A natural blend free from artificial sweeteners, flavorings or colourings
  • Good combination of electrolytes
  • Mixes very well
Cons
  • Not the strongest of flavors
  • Sodium levels are too low to support prolonged exercise

Specifications Product 1
Serving size 1 tablet in 450ml water
Sodium per serving 55mg

Flavors 9 available

In powder rather than tablet form, this vitamin C-rich drink is ideal for everyday hydration and wellness. There's a good mix of electrolytes and a range of nine moreish flavors to choose from (I loved the raspberry and pink lemonade flavors). However, as they are sugar-free, I found the flavors to be milder than other options I tested, so these may not be popular with those who prefer a stronger, more flavorsome electrolyte.

12. ESN Pro Series Electrolyte Powder

Men's Fitness verdict

ESN's convenient sachets hit all the right numbers nutrition-wise but the taste and cost might not be to everyone's liking.
Pros
  • Good range of electrolytes
  • Easy to carry individual sachets
  • One sachet will almost fill a 750ml bottle
Cons
  • Can't escape the salty aftertaste
  • Not the cheapest option

Specifications Product 1
Serving size 1 tablet in 625ml water
Sodium per serving 660mg
Price per serving £1.80
Flavors Natural lemon, neutral, red apple, cherry lollipop

The ESM Pro Series Electrolyte drink has a carbohydrate-electrolyte mix to both fuel and rehydrate you as you work out. Each 22.5g sachet contains 17g or carbs (of which only 1.1g is sugars), as well as a decent dose and mix of electrolytes – with 660mg sodium, 150mg potassium, 59mg calcium and 28mg magnesium.

The high level of sodium is ideal for rehydration but does leave a slightly salty aftertaste. However, the four flavors are quite pleasant and mild and each sachet will give you 625ml of electrolyte-rich fluid. The sachets are ideal for storing in running vests or belts for keeping on top of your hydration strategy in the middle of endurance events. An expensive but effective choice.

13. MyEndurance Hydr8

Best budget electrolyte drink

Pros
  • Designed to suit endurance exercise
  • Wide range of electrolytes
  • Excellent value
Cons
  • Only one flavor
  • A little difficult to dissolve
  • Quite sweet

Specifications Product 1
Serving size 1 tablet in 400ml water

Flavors Orange

Hydr8 tablets are packed with vitamins and minerals with good sodium levels to suit endurance athletes. They're fortified with B vitamins too and work out to be the cheapest electrolyte drink per serving on test. The orange flavor is nice and tangy but a little on the sweet side. Also, I found the tablets didn't mix quite as well as others I tested, meaning I had to shake to get the end residues to combine.

14. Powerbar 5 Electrolytes

  • Good range of electrolytes
Cons
  • Needs 3 tablets to fill a 750ml water bottle
  • Taste may be too sweet and intense for some

Powerbar’s hydration tabs have an intense yet refreshing flavor (I tested the pink grapefruit flavor) and a caffeine kick for a pre-workout pick-me-up. They're sugar-free, too, and come in tiny tubes that we could just slip into a pocket – perfect for hydrating on the go. I also found that the tablets dissolved quickly, with no need for shaking.

15. Humantra Hack #1

Best electrolyte drink

Product shot of Human electrolyte powder

Men's Fitness verdict

Humantra may be an unfamiliar name in hydration but not for long. These all-natural sachets offer plenty of support for intense exercise and hydration – it's just a shame about that high price.
Pros
  • All natural ingredients
  • Plant based and sugar free
  • Contains all six essential electrolytes
Cons
  • Second most expensive on test
  • Only available online
Scroll to see more →
Specifications Product 1
Serving size 1 sachet in 500ml water
Sodium per serving 220mg
Price per serving £1.40
Flavors Elderberry, Himalayan lime, berry pomegranate

Humanatra is a new player in the electrolyte drinks game, and it's ticking all the right boxes. Its sachets contain all six essential electrolytes as well as antioxidants and are made from entirely natural ingredients. Electrolyte amounts are greater than many of the big name brands too.

Its three sugar-free flavors are punchy without being overwhelming and there's your daily dose of vitamins C and B12 in each sachet too. If you can stomach the price, you can't certainly stomach these pleasant flavored and exercise-supporting hydration hits.

Best electrolyte drinks FAQs

Should I take electrolytes before working out?

Starting intense exercise in a state of optimal total body water is important. In some cases, adding electrolytes (sodium) to fluids to promote fluid retention can achieve this. This is especially relevant if you're about to start a long race, competition or hardcore training session.

Can electrolyte drinks help hangovers?

Some people swear by electrolyte drinks to help with the electrolyte imbalances caused by fluid losses during a drinking session. However, there is a lack of research to prove that the severity of a hangover is correlated with a disruption in electrolyte balance or that adding electrolytes to your diet will help lessen the severity of a hangover. In most cases, your body will quickly restore the balance of electrolytes once the effect of alcohol wears off.

Electrolytes are most effective in helping with rehydration during recovery from intense, lengthy exercise, heavy or salty sweaters and those involved in endurance sports. For everyone else, you should be able to get what you need from the food you eat.

Is it OK to drink electrolytes every day?

If you don't need an electrolyte, then there is no point in taking one. It is also worth remembering that these drinks are high in sodium. While athletes may need more in their diet during training and competition, people generally consume too much sodium, which can harm your health and increase your risk of high blood pressure.

You can get all the necessary electrolytes from your food, and most people get more than enough sodium. Eating plenty of plant-based foods such as vegetables, whole grains, nuts, and seeds will ensure a good intake of other minerals from your diet.

How we test the best electrolyte drinks

Nutritionist Rob Hobson has tested the best electrolyte drinks to support your hydration and recovery needs. An award-winning, registered nutritionist and sports nutritionist with over 15 years of experience, Rob is a distinguished expert in the fields of nutrition, health and sports. During the testing process, Rob tested each electrolyte drink for taste, solubility and effectiveness in terms of their hydration and nutritional benefits.

What are electrolyte drinks?

Put simply, electrolyte drinks are specifically designed to help replenish the body's electrolytes – naturally occurring salts and minerals that help balance our bodies' fluids. The best electrolyte drinks typically contain a blend of electrolytes, carbohydrates and other nutrients that work together to help support hydration and recovery. These drinks generally come as a powder or tablet that you dissolve in water.

Electrolytes are minerals that have an electrical charge when dissolved in water, meaning they can conduct an electrical current. The role of electrolytes is to help regulate the body's fluid balance, nerve function and muscle contraction while also assisting with the passage of nutrients in and out of cells.

The electrolytes sodium, potassium and chloride are found in the highest concentrations in bodily fluids such as sweat, blood and urine. The most important one concerning exercise performance is sodium.

What is the role of electrolytes?

Sodium: The most vital electrolyte that helps to maintain body fluid volume. Sodium is often added to sports drinks alongside glucose; glucose increases sodium absorption, in turn facilitating water absorption.

Potassium: This mineral helps to keep your body in a steady state of equilibrium and helps to prevent muscle cramping and weakness.

Chloride: During exercise, we require chloride for proper muscle contraction and transmission of nerve impulses.

When should you take electrolyte drinks?

Hydration is paramount during exercise, and fluid losses of more than 2% body weight can impair coordination, decision-making and overall athletic performance, and even more so in hot climates. The rate at which you sweat can influence how dehydrated you get during exercise, and with this comes the loss of sodium, which is even more significant in 'salty sweaters'.

Straight after a workout is the time that electrolyte drinks are most helpful. After an intense, lengthy training session or event, most people will undoubtedly finish with a fluid deficit. They will need to rehydrate during the recovery period.

If you are competing, having a good hydration strategy in place is advisable, and this includes rehydration during recovery. Consuming fluids alongside sodium in the form of electrolytes and foods can help with fluid retention. Electrolytes during this period can also help replace losses during exercise and are especially useful when you need rapid rehydration due to short periods between competing or training.

Benefits of electrolyte drinks

The role of electrolyte drinks during and after exercise is not to replace electrolytes lost through sweat but for several other purposes:

  • Increasing the palatability of drinks
  • Promoting drinking by maintaining thirst
  • Preventing hyponatremia (low sodium levels resulting from excessive fluid consumption)
  • Increasing the update of water in the body
  • Increasing fluid retention

Should I take electrolytes while exercising?

There is only a benefit to taking electrolyte drinks (sodium) if you lose significant amounts of sweat or are training/competing for an extended period. The rate you sweat can vary and many factors can influence it such as exercise duration and intensity, fitness levels and climate. A sweat rate above 2L/hr would be considered high.

According to the Academy of Sports Nutrition and Medicine, circumstances requiring electrolytes (sodium) during exercise may include a sweat rate greater than 1.2L/h, exercise lasting more than 2 hours or having very salty sweat (your sweat may leave white marks on your kit). Experts suggest that electrolyte (sodium) consumption during exercise is 500-700mg per hour, which is highly variable and dependent on the individual. If someone is unconditioned, training in the heat and humidity, a salty sweater or exercising for several hours, they may need more.

Getting adequate sodium during an endurance or ultra-endurance event can also help prevent hyponatremia, when sodium levels in the blood are abnormally low. The symptoms of hyponatremia include fatigue, dehydration, confusion, slurred speech and vomiting, and if not treated can be life-threatening.
