Powerbar’s 5 Electrolytes hydration tabs have an intense flavour and a caffeine kick for a pre-workout pick-me-up, writes nutritionist Rob Hobson.

Better known for its energy bars, Powerbar also produces a range of the best electrolyte drinks tablets. The Powerbar 5 Electrolytes contain the body’s essential electrolytes to support fluid balance and hydration. The important electrolyte is sodium, and with 250mg in every serving there’s enough here to keep you hydration and to ward off hyponatraemia during prolonged exercise. Powerbar recommends using one tablet with 250ml water per serving.

All flavours of 5 Electrolytes contain 75mg of caffeine, around the same amount as a regular cup of coffee

Powerbar 5 Electrolytes performance on test

These electrolyte tablets are suitable for all sports, including endurance events. To fill a large water bottle (750ml), you’d need to add three tablets which will set the sodium content relatively high. So this may not be the best option for anyone who needs to watch their sodium intake for health reasons.

The tablets are sugar-free and sweetened with sucralose. The pink grapefruit I tested is refreshing, but also a little sweet and a bit too intense, which may not suit everyone. I did find that the tablets dissolved quickly, though, with no need for shaking.

Powerbar 5 Electrolytes limitations

All flavours of 5 Electrolytes contain 75mg of caffeine, around the same amount as a regular cup of coffee. This may suit some people who like to use caffeine before and during training or competition to aid performance, but it’s not ideal for evening sessions.

With only ten tabs in each tube they’re easily pocketable. At 33p per serving they do seem like good value but if you need to fill larger bottles with the recommended dosage it can start to get pricey. There are five flavours to choose from – raspberry and pomegranate, lemon tonic, blackcurrant, pink grapefruit, and mango and passionfruit.

Serving size:1 tablet in 250ml water
Sodium per serving:250mg
Price per serving:33p
Flavours:Raspberry and pomegranate, lemon tonic, blackcurrant, pink grapefruit, mango and passionfruit
