Are you hydrating your athletes properly?


A 'one-size-fits-all' approach doesn't work when it comes to hydration.

Sweat rates and sweat sodium concentrations can vary dramatically (up to 15x) between individuals. (See our Science page for more on that...)

Understanding the unique physiology of your athletes allows the development of personalised hydration strategies that meet their needs based on individual sweat testing, which is crucial to maintaining performance.

We provide the tools, experience and products to do this to an ever-growing list of professional sports teams in the English Premier League, International Rugby Union, the NFL, NBA, MLB, NHL, Formula 1, MotoGP, Indycar, Professional Triathlon and more.

How does it work?

We have a patented medical technology to collect and analyse your athletes' sweat. No blood tests. No labs. No need for them to work up a sweat on a treadmill, or to interrupt training. The Sweat Test can be done at rest, almost anywhere, in around 15 minutes.

The test gives an accurate reading of the athlete's sweat sodium concentration. This is determined by genetics and whilst it varies between athletes, it stays pretty constant within an individual.

We combine our Sweat Test results with contextual information about sweat rate, training levels, cramping history to create an individual hydration strategy for each athlete.

And, because the other hydration products out there follow the 'one-size-fits-all' approach, we've also developed our own range to match each hydration plan perfectly. Our strongest electrolyte product has as much as four time more sodium as the off the shelf brands.

All of our products are independently batch tested at HFL labs to certify that they are free from contamination by banned substances on the WADA anti-doping list. Batch certificates can be provided if necessary.

Why does it work?

  1. No need to disrupt training sessions. (Unlike with traditional patch testing)
  2. It can be done almost anywhere, with little space and no special facilities required.
  3. Test 75+ athletes in one day. 
  4. Results are available immediately and are extremely accurate.
  5. Personalised hydration strategies can be implemented quickly and easily using our own multi-strength electrolyte range.
  6. We've worked within professional sports at the highest level for a long time and bring a depth of experience and knowledge to the service.

    What are the benefits for your athletes?

    Performance maintenance

    The negative effects of dehydration and sodium depletion on performance are well documented.

    Optimizing fluid and electrolyte intake maintains blood plasma volume, which prevents the drop off in performance that occurs when an athlete is dehydrated.

    With properly hydrated athletes, you should get more of this, and...


    Performance enhancement

    Studies have shown that acute pre-exercise sodium loading can actually increase performance, by increasing blood plasma volume. The stronger products in the Precision Hydration range are commonly used for preloading.

    Reduced cramping

    Although the exact causes of cramping are still not 100% understood, there is a large amount of anecdotal evidence to suggest that athletes can reduce the incidence of muscle cramps experienced during and after exercise by maintaining fluid and electrolyte balance.

    ...less of this!

    Hydration awareness and self-management

    Athletes who've taken our Sweat Test are far more aware of their own hydration requirements. This leaves them better equipped to manage their hydration when they're away from the controlled team environment. 

    Increased safety from the extreme downsides of dehydration.

    Sweat testing a group of athletes allows support staff to ‘red flag’ those with the potential for high net sodium losses and take pre-emptive action with them. This is especially important when facing unusually hot or demanding conditions.

    Ok, so what are the options?

    There are 2 options for implementing Precision Hydration within your organisation...

    1. 'Hydration as a Service'

    Our experienced Sweat Experts visit your facility and conduct Sweat Tests with your athletes.

    Up to 4 athletes can be tested every 20 minutes depending on the set up.

    All testing data is immediately reported back to support staff along with initial hydration strategies for each athlete.

    The cost is typically £95 (around $140) per athlete, for a squad of 20. But we always discuss your organisation's exact requirements and make a tailored quote.

    2. DIY Hydration (with plenty of support!)

    Our Sweat Testing hardware can be purchased and includes training on how to conduct and interpret Sweat Tests.
