Why You Need To Replace

Electrolyte Tablets

Electrolytes are crucial for muscle function and hydration, but they're not an energy source. There is also no science to back up the theory that electrolytes prevent muscle cramps. For sustained exercise, you need carbs alongside electrolytes to maintain endurance.

Perple’s innovative all-natural Endurance Mixes leverage the power of real food ingredients, scientifically proven to enhance performance.


How Perple Compares:

The benefits of Perple Endurance Mixes

Ideal to sustaining energy for exercise of multiple hours. You mix the right amounts based on whether you’re doing a steady push, up to maximum effort in competitions.

Being free from caffeine, maltodextrin & ultra-processed simple sugars means you no longer have to endure energy crashes, upset stomachs or headaches. Perple is the only recipe that uniquely combines multiple complex carbs, BCAAs, electrolytes and plant nutrients to deliver sustained endurance.

Try Perple Read the Science

Why we don’t use typical electrolyte tablet ingredients

What we had been led to believe about certain chemical compounds sustaining our endurance, can be the opposite. Worse, many can negatively impact our health, & come from GMO corn, coal tar & petroleum

The stuff that's a health hazard:

Aspartame (from BioDiesel)

Maltodextrin is used as the main ‘energy source’ in leading energy gels & energy drink powders. It's a cheap bioengineered white powder, introduced in the 70s as a food thickener in processed foods. Like instant puds and sauces.[33]And much of it is made using GMO Corn.[34]Regulators might have considered it as safe in the past, but in the context of it being used in 'low moderation'.

But our exposure to Maltodextrin today, is higher than it has ever been. Especially with its high inlcusion in sports nutrition and drinks, which we now consume in greater quantities, and more often.

The problem is that Maltodextrin makes our stomachs more susceptible to disease, owing to changing the balance of gut bacteria. Inflammatory bowel diseases like Crohn's or ulcerative colitis.[1][2][3]

Artificial Flavours (from Petrol)

To make synthetic of ultra-processed ingredients taste better, many producers use artificial flavours. You'll find them in leading sports drinks, and some energy gels and drink powders, but did you know they're made from petroleum.[25] [26]

The stuff that doesn't work:


Caffeine comes from coffee beans, cacao beans, tea leaves, and gaurana berry, to make it sound more exotic. But it isn’t real energy. It heightens nervous systems giving us a fake or artificial rush of energy. While this can help to drive more effort in exercise, it maxes out at one tall starbucks coffee (a 200mg dose) and can’t be sustained. One cup in the morning will last throughout the day and maximize any performance benefits. Then, to supplement at excess doses won’t necessarily give you any added benefit, and you run the risk of side effects. Such as irritability, tremor, heart-rate increases, headaches and fatigue.[8] [9] [10]


There is no doubt among researchers that prolonged and intense exercise causes oxidative stress. Which in turn can result in increased muscle fatigue. Therefore, some promote anti-oxidant supplementation during exercise, to overcome these effects. Yet, after a thorough review of the scientific literature, there is little evidence to conclude that this approach helps.[11][12] In fact, we find strong evidence that supplementation can actually inhibit the body’s natural biological defences to oxidative stress. What this means is that natural adaptive responses by your muscles can be lessened, and your capacity for endurance reduced.[13][14][15] If you’re consuming well-balanced daily meals, you should be receiving adequate supplies of these anti-oxidants.

Vitamin B

There is sound scientific evidence to conclude that B-Vitamins play an important role in energy metabolism. Then, it seems reasonable that any deficiencies might lessen exercise performance. But, if you’re getting everything you need from your normal diet, excess doses above recommended upper limits, could be harmful. For instance, excess B2 can cause diarrhoea and polyuria, B3 liver problems, gout and irregular heartbeat, and B6 nerve damage.[16][17][18] When it comes to vitamins, we believe you should only supplement for known deficiencies. Otherwise toxic doses can result in serious health problems.

Suggested use:

For the enthusiasts.

You’re out there for the love of it. You stay fit and hit PB’s for fun.

1 to 3 Hours

Per Hour: 50ml Perple Endurance Mix added to 200 - 300ml of water.

Example of a 2 hour run / ride:100ml of Perple Endurance Mix added to at least 400ml water, to make a 500ml drink, in either of a Perple soft flask or bottle. Consume through your 2 hours of activity.

  • Top Tip 1: If you’re a heavier sweater or in a hot climate, simply mix with more water. For example, add 50ml concentrate to 300ml of water, to make a 350ml drink, for each hour. But, as a general rule, never consume more than 800ml of any fluid in any 1 hour.
  • Top Tip 2: If you run with a vest, belt, or ride with multiple bottle cages, a backpack, or pocket cycle-shirt, always take a reserve 200ml pack of Perple Endurance Mix, and a spare Perple soft flask / bottle of water. Because, if you’re flagging in that 3rd hour, but want to push on, you can always take another 50ml hit of Perple, mixed with at least 200ml of water. Meaning, you would have doubled your dose, in that 3rd hour to 100ml Perple Endurance Mix, mixed with 400ml of water.

Longer than 3 hours (eg: marathon distances)

Per Hour: 100ml Perple Endurance Mix added to at least 400ml water.

Example of a 4 hour road marathon:You’re going to need 2 x 200ml packs of Perple Endurance Mix, a Perple 500ml soft flask or bottle, and a running belt/vest. That’s 8 x 50ml portions. Mix 100ml, with 400ml water in a flask / bottle, to make a 500ml drink. It’s with you at the start, and consume during your first hour. Hold your remaining Perple Endurance Mix portions in a running belt / vest, ready to mix the same again, to make another 500ml drink at a water station, one hour into the race. To then consume in that 2nd hour. Repeat for every subsequent hour.

  • Top Tip 1: If you’re a heavier sweater or in a hot climate, simply mix Perple Endurance Mix with more water, but as a general rule, never consume more than 800ml of any fluid, in any one hour.
  • Top Tip 2: If you run with a vest, you could make ready 2 x 500ml soft flasks to cover you for the first 2 hours, meaning you only have to stop at 1 water station, to make a further 2 x 500ml mixes, for the second half of the marathon.
For the competitors.

You’re super fit, and serious about competition. You target marginal gains and PB’s.

1 to 2 Hours

Per hour: 75ml of Perple Endurance Mix added to at least 300ml water

Example of a 2 hour run / ride: 150ml Perple Endurance Mix added to 600ml water, to make a 750ml drink. Consume during your 2 hours of activity.

  • Top Tip 1: If you sweat heavily or are in hot conditions, mix Perple Endurance Mix with more water. But, as a general rule, do not exceed 800ml per hour.

2 to 3 Hours

Per hour: 100ml of Perple Endurance Mix added to at least 400ml water

Example of a 3 hour run / ride: Could mix total requirements in 3 x 500ml Perple soft flasks / bottles. Or alternatively in a 1.5L hydration bladder, if you run with a vest or ride with a backpack.

  • Top Tip 1: The average athlete consumes 500ml of fluids per hour. But if you sweat more, you can mix Perple Endurance Mix with more water. As a general rule, never consume more than 800ml of any fluid, in any 1 hour.

Longer than 3 hours

Per Hour: 150ml of Perple Endurance Mix added to 600ml of water

Important: With nutritional training, 150ml of Perple Endurance Mix can be mixed with 450ml of water, to make a 600ml drink to be consumed every hour. Giving you 60g carbs per hour, but in a lower solution.

For the extreme: If you compete in ultra or extreme events you can take up to 200ml (80g carbs) of Perple Endurance Mix, added to 600ml of water, to make an 800ml drink, per hour. We advise that you train at these intake levels first before taking into a competition.

  • Top Tip 1:Kidney urine excretion maxes out at 1.2l of water per hour, for experienced extreme athletes. For the rest of us, we advise drinking a maximum of 800ml per hour.

Frequently asked questions.

Read Full FAQ List

What are electrolyte tablets good for?

More generally, electrolyte supplements are good for replacing those that we lose in sweat or other fluids, during sports, exercise and illness. They help to stop you from overheating, to regulate your heartbeat, and to help your muscles keep working hard. They’ll also help to recover from a stomach bug or the flu. However, it’s also important to take them with other macro nutrients, like carbs, because they will not give you enough energy to sustain your activities alone. Perple has all the nutrients you need to keep you energized and well hydrated during your fitness regimes, challenges and adventures

Can you take electrolyte tablets every day?

It really depends. If you are exercising regularly and are losing alot of fluids, then to restore electrolytes with the use of certain supplements is helpful. Electrolytes are important to help maintain normal body functions during our physical activities. But, if you’re relatively sedentary and have a good diet, then there is no need to supplement with electrolytes. People with kidney disease or impairments should be particularly careful. Because their kidneys might not be able to dispel excess electrolytes, which could cause further health problems. And if you have high blood pressure, but don’t exercise much, to supplement with electrolytes could cause your blood pressure to rise further. Perple is designed to maintain a good balance of electrolytes in your system during sports and exercise, replacing those which you lose in your sweat. Plus, the electrolytes in Perple are combined with carbs, and BCAAs to give you everything you need to stay energised and well hydrated.

Who should not use electrolytes?

People with kidney disease or impairments should be particularly careful as their kidneys might not be able to dispel excess electrolytes, which could cause further health problems. If you have high blood pressure, but don’t exercise much, supplementing with electrolytes could cause your blood pressure to rise further.
