When you are logging heavy miles, especially during the warmer summer months or intense marathon training blocks, plain water simply is not enough. Replacing the sodium and trace minerals lost through sweat is the only way to stave off dreaded mid run muscle cramps and ensure your body continues to perform efficiently.
However, the traditional running hydration market is flooded with overly sweet, artificially coloured sports drinks and effervescent tablets that often cause more gastrointestinal distress than they cure.
Enter Puresport Electrolytes. Born out of the booming UK run club scene, Puresport has built a massive cult following by stripping away the synthetic additives. Instead, they focus on clean, highly functional natural ingredients like Pink Himalayan salt, freeze dried coconut water, and zero refined sugars.
But does a natural, zero sugar hydration powder actually hold up when you are deep into a gruelling 20 mile long run? I have been testing the Puresport Electrolyte tubs over the last few weeks to see how they mix, how they taste, and whether they justify their premium price tag. Here is the full review.
Puresport Electrolytes at a Glance
- Who it is for: Runners logging heavy summer miles who want to prevent cramping and dehydration, but absolutely loathe the sickly sweet, artificial taste of mass market sports drinks.
- The Experience: It mixes flawlessly into a standard soft flask with zero gritty residue at the bottom. Because it relies on natural fruit extracts and coconut water powder, the flavour is incredibly clean, light, and refreshing.
- The Verdict: A premium, stomach friendly hydration powder. The heavy hit of sodium from the Pink Himalayan salt is exactly what heavy sweaters need during intense marathon training blocks.
WHO ARE PURESPORT?
Puresport is a UK sports and wellness company founded in 2018 by former professional rugby players Grayson Hart and Adam Ashe. The brand built its reputation through sports focused CBD products but has now expanded into a broader performance and wellness range, which includes hydration, recovery and sports nutrition supplements.
Puresport appears to uphold a community first approach, in which running has become a big part of the company's identity through its network of run clubs, partnerships with elite athletes and visibility at some of the biggest marathon events.
In 2024, Puresport launched its Ultra Electrolytes range, designed to help athletes replace the minerals lost through sweat. Their message is essentially; water alone doesn't replace everything you lose during exercise.
Sweat contains electrolytes, particularly sodium, and sodium losses can vary dramatically depending on the individual, environmental conditions and exercise intensity. Rather than creating a low dose hydration tablet, Puresport opted for a more substantial formula, providing 1,000mg of sodium per serving.
INGREDIENTS
Each sachet contains
- 1,000mg sodium (from sodium chloride)
The main electrolyte lost through sweat and the main ingredient in the formula.
- 250mg potassium (from potassium chloride)
Helps maintain fluid balance and supports normal muscle function.
- 100mg magnesium (from magnesium citrate): Contributes to normal muscle function and electrolyte balance.
- 50mg calcium (from calcium citrate): Supports muscle contraction and nerve signalling.
- Malic acid: Used as an acidity regulator.
- Natural flavouring
- Stevia natural sweetener.
- Beetroot powder (natural colouring)
One thing I like about the ingredient list is that it’s simple. There are no unnecessary extras and everything included has a clear purpose. They are also sugar free.
The electrolytes aren’t a replacement for your carb fuelling, so when I am doing a long marathon session, I’ll still take gels with me. The electrolyte is there for hydration while my gels provide the energy I need to keep running.
USAGE INSTRUCTIONS
The electrolytes come in individual sachets that you pour into water, shake and drink.
Puresport recommends mixing one sachet with 500ml to 1 litre of water, depending on your hydration needs. I haven't been particularly strict about measuring the water, but I tend to prefer a stronger flavour, so I usually mix a sachet with around 400ml. Partly, because I don't want to drink too much fluid before a run, especially as I don't have the biggest bladder, but I also enjoy being able to taste the electrolytes. If you prefer a subtler flavour, you can add more water.
For me, one of the biggest advantages is how convenient the sachets are. They're small enough to fit into my running shorts pocket alongside my gels making them ideal for longer runs and race days without adding any noticeable bulk.
I also like the flexibility they offer. Rather than carrying around a bulky tub or preparing drinks in advance, I can take a sachet with me and mix it whenever I need it.
On several occasions, I've carried one in my shorts pocket for miles, where it's been exposed to plenty of sweat and movement, yet the sachet has remained intact without tearing or leaking. It's a small detail but makes a big difference when you're out running for several hours and need products you can rely on.
HOW I USE PURESPORT ULTRA ELECTROLYTES
I used to only use electrolytes before races, but over the last year they've become a regular part of my marathon training routine.
The main time I use them is before a race or a hard training session. If I've got a long run, a tough marathon session, or a race coming up, especially in warmer weather, I'll usually have an electrolyte drink beforehand.
On race days, I’ll mix a sachet into a bottle with my breakfast and sip it throughout the morning as part of my pre race routine. During marathon race week, I'll typically have one sachet a day in the lead-up to the race to help stay on top of my hydration and arrive on the start line feeling as prepared as possible.
I also use the electrolytes after longer or more demanding sessions, particularly when I've been sweating heavily. I find they help me replenish what I've lost through sweat and get on top of my hydration more quickly. Having one after a tough session feels like an easy and practical way to rehydrate, and I feel it supports my recovery when my body has worked particularly hard.
I don't use them after every run. If I've only been out for an easy recovery run or a shorter session, water is usually enough. I prefer to use them when I feel they're most beneficial rather than making them part of every single run.
For me, Puresport ultra electrolytes are most valuable when training gets longer, harder, or hotter. For me, those are the situations where hydration can have a real impact on how you feel, perform, and recover.
FLAVOUR AND TASTE
Puresport ultra electrolytes are available in a range of flavours, including Citrus Salt, Raspberry Salt, Watermelon Salt and the new limited edition Pomegranate, which was developed in collaboration with British sprinter Amy Hunt.
Having tried several flavours from the range over the past year, the Pomegranate version is currently my favourite. One of the things I like most about it is that you can taste the flavour. Some electrolyte drinks can be quite weak or watered down, but the pomegranate flavour comes through well. It's fruity, slightly tart, and refreshing without being overly sweet, making it easy to drink before or after a run.
I particularly enjoy it after a hot training session. I've often added ice to it when I get home from a run, which makes it feel more like a refreshing post run drink while also helping me replace some of what I've lost through sweating.
You can taste the salt, especially when you first start using them. With 1,000mg of sodium per sachet, that's hardly surprising. Personally, though, I prefer that. It reassures me that I'm getting a meaningful amount of electrolytes rather than drinking something that just tastes like flavoured water. The more I've used them, the more accustomed I've become to the salty taste.
There is a slight stevia aftertaste, but I don't find it particularly noticeable, especially compared with some other sugar free sports drinks I've tried.
PRICE
A 30 sachet pack of Puresport ultra electrolytes costs £33, which works out at approximately £1.10 per serving. There are subscription options available, which help bring the cost down if you're using them regularly.
They aren't the cheapest electrolytes on the market and there are more budget friendly options out there. However, when it comes to products that I use consistently, I tend to focus more on value than simply choosing the lowest price.
I've tried a variety of electrolyte and hydration products over the years, but Puresport is one of the few that has become a permanent part of my training routine. For me, the combination of the higher sodium content, flavours that I enjoy drinking, and the convenience of the individual sachets makes the extra cost worthwhile.
I also find that some cheaper electrolyte products taste quite weak and don't feel particularly effective. With Puresport, the stronger taste and higher sodium content make me feel like I'm replacing what I've lost through sweat, especially after longer runs, harder workouts, or training in hot weather.
It's worth noting that Puresport offers free UK delivery on subscriptions and orders over £50, alongside a 100% performance guarantee. If the product isn't right for you after 30 days, they offer a refund, and unopened products can be returned within 21 days of delivery. That makes trying them a little less of a risk, particularly if you're unsure whether they'll suit your training needs.

FREQUENTLY ASKED QUESTIONS
When should runners drink electrolytes? For intense sessions or long runs over 60 minutes, it is highly beneficial to "pre-load" by drinking a serving of electrolytes an hour before you run. Alternatively, sipping them throughout a long effort or immediately afterwards is crucial to replace the sodium lost through sweat and fast track your recovery.
Why does Puresport use Pink Himalayan Salt? Standard table salt is heavily processed. Pink Himalayan salt is a natural alternative that contains up to 84 trace minerals, including magnesium and potassium. This makes it far more effective at preventing muscle cramps and regulating fluid balance in endurance athletes.
Do Puresport electrolytes contain sugar? No. Puresport formulates their hydration powder with zero refined sugar, relying on natural ingredients and sweeteners to provide a light flavour. This prevents the harsh insulin spikes and sticky mouthfeel associated with traditional energy drinks.
CONCLUSION
As my marathon training has become more serious, I've realised that hydration is something that deserves just as much attention as pacing, fuelling and recovery. It's easy to focus on mileage and strength sessions, but turning up to a session or race properly hydrated can make a huge difference to how you feel and perform.
Over the last year, Puresport ultra electrolytes have become a regular part of my training routine. I use them before races and harder sessions, throughout race weeks, and after long runs or workouts where I've lost a lot through sweat. They've become one of those products that I reach for automatically because they fit easily into my routine.
What stands out most for me is that they feel effective. The higher sodium content gives me confidence that I'm replacing what I've lost, rather than drinking flavoured water. Compared to other electrolytes I've tried, I find the difference noticeable. Before trying Puresport, I honestly didn't realise how much variation there could be between electrolyte products. Since using them, I've gone back and tried a few alternatives, and they often feel weaker in both taste and effect.
The limited edition pomegranate flavour, created with Amy Hunt, is my favourite flavour. It's refreshing, easy to drink, and has enough flavour that I look forward to having it after a run. Adding ice after a hot session almost makes it feel like a treat, while still serving a practical purpose in helping me rehydrate.
Perhaps the biggest compliment I can give is that I've continued to buy and use them long after my first box. In a market full of sports nutrition products, that's not something I do often. I feel more refreshed, energised, and recovered when I consistently use them around harder training sessions.
I'm a big fan of Puresport ultra electrolytes and, for me, they set the standard for what an electrolyte drink should be. I didn't realise there was such a noticeable difference between electrolyte products until I started using them regularly and comparing them with other brands.
