The best electrolytes 2025 – tried and tested
Struggling with poor sleep, fatigue or headaches? You may be dehydrated and low in electrolytes. Read our guide to the best electrolytes as well as information on when to take them, the best forms, and more
If you're not sleeping well, feeling tired or even experiencing headaches you may be dehydrated and lacking in key minerals, known as electrolytes. Among these are sodium, potassium, magnesium and calcium, which conduct electricity when dissolved in fluids, making them essential for regulating chemical reactions in the body so our nerves and muscles can function properly. Electrolytes also maintain our fluid balance, help the heart to work and regulate our blood pressure.

How we tested electrolyte supplements
Our key criteria were price (which we judged by the cost of a recommended daily dose), the percentage of nutrient reference value (where relevant) provided in the recommended dose of each product, and how the product format (powder, tablet, drink, chew etc) and form of minerals might affect the amounts absorbed by the body.

Our tester rated this highly, although the powder and water needed to be shaken well. She found it provided a welcome boost of energy and hydration on her long runs without causing stomach issues. Made from freeze-dried fruit, the four flavours include an electrolytes only (‘Solo’), added carbs as cane sugar (‘Passo’ and ‘Vivo’), or added carbs and caffeine option (‘Attivo’). This was one of the pricier in our trial but also one of the most liked.

In addition, each tab provides 18 essential micronutrients, including vitamin B12 making it a useful option for vegans. Our tester found the berry flavour an acquired taste, although it did dissolve more quickly than other products.
Available from:
SiS Hydro tablets with added B vitamins
Available from SiS (£8)
Best electrolytes for value for money
Price per dose: 40p
Star rating: 4/5
Convenient and inexpensive, these tablets were slow to dissolve but created a hydrating and energising electrolyte drink. Designed to provide sodium at a specific concentration (30mmol/L) for improved hydration, our tester enjoyed the gentle fizz and flavour of this product.
Available from:
HIRO Hydration tablets
Available from HIRO (£24)
Best electrolytes for interesting flavours
Price per dose: 80p
Star rating: 4/5
These convenient tablets offer a pleasant, tea-like flavour without the typical salty taste of electrolytes. The ginger and lemongrass variety was especially well received. However, they dissolve slowly and contain sweeteners and additives like maltodextrin. While the mineral balance is decent, some product claims were inconsistent in terms of how much more hydrating than water they are. Still, they’re a solid option for those seeking an alternative to overly sweet or artificially flavoured hydration products. Watermelon and lemon and elderflower flavours are also available.

What are electrolytes?
The electrolytes our bodies rely on include sodium, potassium, chloride, bicarbonate, calcium, magnesium and phosphate. Of these, we can make bicarbonate ourselves and sodium chloride or table salt is quite easily obtained from the diet. The majority of us who eat a varied, balanced diet and don’t sweat too often, should get the other electrolytes we need from fruit, vegetables, nuts, dairy, high quality sources of protein and plain water.
However, if you do fall into a category that may benefit from supplementation, look for a product that provides a balanced mix of these essential electrolytes, because electrolytes interact together. How much of these minerals you’ll need will depend on your specific circumstances.
When should you take electrolytes?
We lose electrolytes through body fluids such as sweat and urine, this means those who benefit from supplementation most, are likely to be endurance athletes and hard-hitting gym-goers as well as marathon runners, especially those who compete in hot, humid conditions.
If you're a gym goer and not sure if this is you, the general rule is if your activity doesn’t involve much sweating or is less than an hour in duration, the electrolytes found in whole foods should be sufficient. If your activity lasts longer than an hour or is in extreme heat, an electrolyte product may be helpful.
The other occasions when an otherwise healthy individual may benefit from supplementation, is after bouts of sickness and diarrhoea, and possibly after a heavy drinking session, because excess alcohol may lead to dehydration which can throw your electrolyte levels out of balance. Signs of dehydration include excessive thirst, dark-coloured urine, a need to urinate less frequently and skin that when pinched is slow to return to its normal position.
Consuming too many electrolytes, just as too few, may lead to an imbalance and in severe cases cause symptoms like weakness, headache, tremor, cramping, confusion and a rapid heartbeat. If you do supplement always check pack instructions carefully and don’t take more than the recommended amounts.
Only use electrolyte supplements when needed, such as after strenuous exercise, excessive sweating or illness. If you’re on prescribed medication, including diuretics, refer to your GP for guidance.
What is the best form of electrolytes?
Electrolyte powders, ready to go drinks, salt chews and dissolvable tablets are designed to restore the body’s levels of electrolytes and promote rehydration in an optimal way. The best product for you is the one that works well for your specific needs, preferences and lifestyle. Look for a product that provides a balanced mix of essential electrolytes along with carbs, like glucose, as this will help deliver water to the cells quicker.
