Precision Hydration

Are Precision Hydration's electrolytes batch tested / certified safe for use in sport?

All of our products are independently batch tested for a wide range of prohibited substances on the World Anti-Doping Agency (WADA) list. We can provide batch certificates on request.

Our all-natural drink mixes are also Informed Sport / Informed Choice certified.

What's the difference between the all-natural drink mix packets and the effervescent tablets?

Our multi-strength electrolyte supplements come in three different formats and the differences between them is something we're asked a lot. 

This blog breaks down the differences between our 3 different types of electrolyte supplement.

Which strengths are right for me?

Our exercise-free, Advanced Sweat Test tells you your sweat sodium concentration and we developed an algorithm-based free Online Sweat Test to give you a decent idea of which strengths you’re likely to need, which you can then refine in training.

Whilst the Advanced Sweat Test is the gold standard, the online test has genuine efficacy. We sent thousands of data points from our Advanced Sweat Tests to a leading university here in the U.K. and they found a strong correlation between how salty athletes think their sweat is and reality.

What flavour is Precision Hydration?

All of our products have a light citrusy flavour (with the exception of SweatSalt capsules, which are designed to be swallowed whole with water). Thousands of athletes have tested our products and the feedback is always positive - the most common feedback is that our drinks "taste a bit like flavoured water". We worked very hard to ensure it's nice to drink, even during intense exercise. 

The different colours on our packaging represent the different amounts of sodium each of our products contain, from 250mg of sodium per litre (320z) of sweat up to 1,500mg/l (32oz).

Where is Precision Hydration made?

Our all-natural drink mixes are made in the U.K.

Our effervescent tablets are made in Germany and the USA.

Our SweatSalt Capsules are also made in the U.K.

What's in the PH 500 / 1000 / 1500 all-natural drink mixes?

Our all-natural drink mixes contain just 8 natural ingredients.

The key one is sodium and in the all-natural range, this comes in the form of Sodium Citrate, which is alkaline and therefore much easier to drink in larger volumes and more suitable for the body when exercising, which is great if you're prone to GI issues on longer/hotter events when you're drinking more.

The drink mixes also contain base amounts of potassium, calcium and magnesium, similar to the low levels found in normal human sweat. Unless you have a deficiency in these electrolytes, you needn't worry so much about them, it's sodium that is most important to staying hydrated and this is the electrolyte that makes up most of your sweat (alongside water) - that's why it tastes salty! 

Oh, and there’s also a little bit of citric acid and vitamin C, just to help with the taste and improve the stability of the products when they’re stored in your cupboard before use.

The light citrusy flavour comes solely from natural fruit extracts; the glucose comes from simple cane sugar.

There are no artificial or synthetic ingredients in the all-natural drink mixes. This was really important to us as we are aware that more and more athletes are seeking to minimise or eliminate these from their diets. 

The drinks are suitable for vegetarians and vegans and they’re gluten, dairy and GMO free. We followed the basic principle that we’d only put in exactly what was needed to make a useful and great tasting hydration drink. Nothing more.

The all-natural drink mixes are also Informed Sport / Informed Choice certified and tested, so you needn't worry about them containing anything on the WADA anti-doping list.

Why is there sugar in the all-natural PH 500 / 1000 / 1500 drink mixes?

Our all-natural electrolyte drinks contain a bit of sugar and some people ask questions about that as sugar has a bit of a bad rep these days! 

But, when Mary Poppins sang “a spoonful of sugar helps the medicine go down”, she really was on to something. You see, a small amount of sugar (glucose) in a solution significantly improves the movement of water into the body when paired with plenty of sodium. Our hypotonic hydration formulas take advantage of this using a well researched mechanism called ‘sodium glucose co-transport’ to increase the rate at which fluid gets into your body. 

It's basically the same concept used in medical oral rehydration solutions to rapidly rehydrate those suffering from severe dehydration from sickness and diarrhoea who can’t be given a drip, so it has a lot of efficacy behind it. 

As well as helping you absorb fluid faster to stay hydrated, sugar also has the side benefit of helping keep your energy levels up during prolonged exercise. Don’t misunderstand us here, sugar, like anything in excess, is not good for you and our products are in no way ‘energy drinks’. 

But, for active athletes, consuming sugar appropriately really makes a lot of sense, especially when you’re working hard. In actual fact (and despite the bashing they receive in the more popular press on a regular basis), carbohydrates are still up there as the most proven and potent substances athletes can legally consume to maintain endurance performance. 

As with most things in life, moderation is the key word here. A single 20g serving of Precision Hydration (mixed into 500ml/16oz of water as directed) creates a hypotonic 3% carbohydrate solution. That’s the optimal amount for fluid absorption and less than half the level found in typical isotonic drinks such as Gatorade, Powerade and Lucozade Sport. 

Each packet of PH 500/1000/1500 delivers just under 70 Kcal per 500ml/16oz serving and approximately 15g of carbohydrate per 500ml/16oz. This means that most athletes will definitely still need to get the majority of their calories from foods or other solid nutrition products.  But that's exactly how it should be: Rapidly absorbed fluids from your bottles and calories from solid foods. You can then dial hydration, sodium and calorie requirements up and down independently to suit whatever you're doing, whatever the conditions.

What's in the PH 250 / 500 / 1000 / 1500 low-calorie effervescent tablets (in the tubes)?

Our effervescent tablets are low calorie, making them the best option for anyone on a LCHF diet, anyone fasting to burn more fat or those with diabetes or other conditions that require a reduced sugar intake.
