Electrolytes are having a major moment, with influencers and celebs frequently reaching for their refreshing supplements. But what are electrolytes – and how do electrolyte drinks compare to sports drinks? Let’s dive in. Electrolytes are a group of essential minerals, including sodium, potassium and magnesium, which all play a key role in fluid balance – along with your tall glass of water. They can also impact how quickly we feel after a workout. Why? When you sweat it out in a vigorous session (hello, hot Pilates class), you lose these vital minerals too.1
This is where electrolyte drinks and supplements come in. Whether you prefer powders, tablets or ready-to-drink options, they can help replenish what’s lost and support your electrolyte balance.
Electrolyte supplements vs sports drinks
Electrolyte supplements and sports drinks are often used interchangeably but they’re designed for slightly different purposes. Electrolyte supplements focus on replenishing key minerals like sodium, potassium and magnesium to support fluid balance, without adding significant calories or sugar. This makes them a popular choice for everyday on-the go workout drink, lighter workouts or staying refreshed in warmer conditions.
Sports drinks, on the other hand, combine electrolytes with carbohydrates (sugars) to provide both hydration and a quick source of energy. These can be particularly useful during longer or more intense training sessions. Key differences at a glance are:
- electrolyte supplements: focused on hydration, typically lower in sugar and calories. Best for everyday workouts and hydration
- sports drinks: combine hydration with energy and are best for endurance or high-intensity sessions
Electrolyte powders vs tablets: what’s the difference?
Both electrolyte powders and tablets are designed to be mixed with water to support fluid balance, so they ultimately do the same job. The main difference comes down to how you use them. Powders tend to offer a bit more flexibility, as you can adjust the amount or strength to suit your needs, and they often come in a wider range of flavours. Whereas tablets are pre-measured and easy to carry, making them a convenient option for travel or keeping in your gym bag. It really comes down to personal preference and what fits best into your routine.

Electrolyte FAQs
Electrolytes can be taken before, during or after exercise depending on your needs. If you’re training intensely or sweating a lot, having them during or after your workout can help support hydration and recovery.
Electrolytes help replace minerals lost through sweat, which can support hydration after exercise. Staying properly hydrated is an important part of overall recovery, especially after longer or more intense workouts.
For shorter or low-intensity workouts, water is usually enough. However, if you’re exercising for longer periods, sweating heavily or training in hot conditions, electrolyte supplements may be a helpful addition.
The final say
Electrolytes can be a simple way to support fluid balance and performance – especially if you’re training regularly or pushing your limits. If you’re just getting started, a powder or tablet mixed with water can be an easy first step. For convenience, ready-to-drink options can slot into even the busiest routines. Ultimately, it’s about finding what works for you – whether that’s a quick sachet post-workout or simply increasing your water intake.
