Precision Hydration Sweat Tests

We'd wager that you don’t pay much attention to your sweat loss during exercise? But you should. It's crucial to your performance. 

Rather incredibly, the amount of sweat /sodium lost can vary up to 15 times between seemingly similar individuals.

Everyone loses a different amount of sodium in their sweat, from as little as 200mg per litre of sweat, to as much as 2,000mg/l - this is largely genetically determined.

This means that a 'one-size-fits-all', off the shelf approach doesn't work when it comes to hydration.

We offer a personalised hydration plan and a mix of products that meet your individual needs.

What is Sweat Testing?

We offer two types of Sweat Test, both backed up by science and working with thousands of athletes.

Our Advanced Sweat Test

Sweat testing equipment

​No blood test. No need to bust a gut on a treadmill. No need to wait whilst your sample goes off to a lab for top secret analysis.

Our Sweat Test takes about 45 minutes and all you have to do is sit comfortably whilst we talk to you about how you train, compete and walk you through your Personalised Hydration Strategy. The test is simple, painless, and extremely accurate.


This gives us an accurate reading of the amount of sodium (the key electrolyte lost in sweat) you lose every time you exercise. This is largely genetically determined and it's relatively stable after infancy, and so in most cases you'll only need one test in your life in order to understand an important part of the hydration equation.

We combine the reading with the context you give us during the test to create a hydration strategy just for you. We'll advise you on when, what and how much to drink before, during and after training and competitions, so that you're well equipped to achieve your goals.

We'll recommend what strength electrolyte drinks will work best for you in each scenario too. We developed these multi-strength electrolyte tablets because the off the shelf products out there just don't do the job for most people. Our strongest product, PH 1500 has up to 3.5 times more electrolytes than other brands you might have used before.

We have exclusive access to this fully patented testing technology for sweat testing athletes. It has a long and credible history in medicine as a diagnostic tool for some Cystic Fibrosis. We've also been granted US Patent (Pending) for the concept of providing personalised hydration strategies through an accurate sweat test.


Our Online Sweat Test

We've built up such a wealth of data on how athletes sweat that we were able to build an algorithm-based questionnaire to deliver personalised hydration advice even if you can't make it to one of our test centers.

Of course, only our Advanced Test can tell you exactly how much sodium you lose in your sweat, but our Online Sweat Test can make solid recommendations on how you should be hydrating which you can refine (with our help) through testing when you're out there doing what you love.

Our mission is to give every athlete access to a personalised hydration strategy so that they have the best chance of achieving their goals. If you're unsure which test is right for you, get in touch and we'll help you decide.
