Precision Hydration

Precision Hydration is a UK company launched in 2011 and has developed over the years with top athletes and technology partners a simple and effective way to help athletes understand and manage their individual hydration needs.

The founder, Andy Blow, has a degree in sport and exercise science and in his youth, he regularly finished on the podium in short course triathlon races.

However, he had poor results in races in the heat and over longer IRONMAN distances. He suffered from cramps and other hydration problems, including hyponatremia (low blood sodium, which can have serious consequences), despite the widely accepted hydration advice at the time.

About the company

After years of trial and error, he finally understood how to effectively manage his individual sodium and fluid intake to maintain performance.

He was greatly assisted in this process by Dr. Raj Jutley, a highly respected cardiac surgeon, who introduced him to the concept of sweat testing and the huge variation in sweat and sodium loss that can occur from one athlete to another.

It was through his own search for an effective solution that, with Dr. Jutley’s input, the concept of precision hydration was born.

As things progressed, we gained exclusive access to patented perspiration testing technology that requires no physical effort on the part of the athlete. This technology has a long and credible history as a diagnostic test for cystic fibrosis and is simple, non-invasive, painless and extremely accurate.

We also developed our own line of electrolyte supplements early on, as existing products were simply not powerful enough to meet the needs of the most demanding athletes.

When it comes to hydration, the “one size fits all” formula is not enough. Just look at our team: Andy loses more than three times more sodium per liter of sweat than Dr. Raj!

The team has grown with the arrival of Jonny Tye, a paddler who won two silver medals at the Junior World Championships before getting involved to further develop our products.

Word quickly spread that we were offering a unique and personalized hydration solution. We soon offered our services to a growing list of professional sports teams from the English Premier League, International Rugby Union, NFL, NBA, MLB, NHL, Formula 1, MotoGP and Indy Car, as well as elite individuals from the world of cycling, running, triathlon and other disciplines.

We’ve even worked with railway workers, firefighters and the military, who are exposed to high levels of heat stress and perspiration, helping them maintain their performance in the most challenging environments.

We are now accumulating so much data on how athletes sweat that we have been able to develop a free, algorithm-based questionnaire to provide personalized hydration advice even if an athlete is unable to visit one of our perspiration testing centers.

Our mission is to give each athlete access to a personalized hydration strategy so that they have the best chance of achieving their goals.
