Precision Fuel & Hydration, originally known simply as Precision Hydration, is a British sports-nutrition company specializing in personalized hydration and endurance fueling. The company is particularly associated with electrolyte products designed around the concept that athletes lose different amounts of fluid and sodium through sweat, meaning hydration should not necessarily follow a one-size-fits-all formula. 1

Its product range is aimed primarily at endurance and high-sweat activities such as running, cycling, triathlon, swimming, team sports, and motorsport. The company also works with professional sports organizations and individuals working in hot or physically demanding environments.

Company Details

The company states it was launched in 2011, following founder Andy Blow’s experience as an endurance athlete and sports scientist. 2

Origins

The story of Precision Hydration begins with Andy Blow, who studied Sport and Exercise Science at the University of Bath and later worked as a sports scientist in motorsport, including with the Benetton and Renault Formula 1 teams. He was also a competitive triathlete.

Blow experienced significant problems with cramping, hydration, and hyponatremia during hot and long-distance races. This experience was pivotal because he was following conventional hydration advice available to athletes at the time but still encountered issues.

His investigation eventually led him to sweat testing, which demonstrated that individuals can differ substantially in both their sweat rate and the amount of sodium they lose through sweat.

That observation became the foundation of Precision Hydration’s philosophy:

Hydration requirements are individual.

Rather than assuming that every athlete should drink the same amount of water or consume the same amount of electrolytes, the company attempts to estimate an athlete’s requirements and match products accordingly.

Development of the Sweat-Testing Concept

Blow was assisted in developing this approach by Dr. Raj Jutley, who introduced him to sweat testing and the substantial variation in sweat and sodium losses between individuals. Precision states it subsequently gained access to patented sweat-testing technology derived from technology with a history in cystic-fibrosis diagnostics.

This became an important differentiator for the brand.

Instead of simply selling an electrolyte drink, Precision Hydration positioned itself as a combination of:

• Sports-science advice
• Sweat testing
• Personalized hydration planning
• Electrolyte products
• Athlete education

The company also developed its own electrolyte products because it considered many existing sports drinks insufficiently concentrated in sodium for some serious endurance athletes.

The central concept behind Precision is individualization.

People do not all sweat at the same rate, and their sweat does not contain the same concentration of sodium. Precision therefore offers multiple electrolyte strengths rather than one universal formulation. Its current range includes PH 500, PH 1000, and PH 1500, with the number referring broadly to the sodium concentration per litre of prepared drink.

For example:

• PH 500 — Moderate-strength electrolyte product
• PH 1000 — High-strength electrolyte product
• PH 1500 — Very-high-strength electrolyte product

The company states its stronger products are generally intended for people with higher sweat/sodium losses and for exercise in hotter or more humid conditions.

One of the most recognizable characteristics of the Precision Hydration brand is that the colored-strength system makes sodium concentration a central part of the product architecture.

Sweat Testing

Sweat testing is arguably Precision’s most distinctive service.

The underlying idea follows this logic:

Exercise → sweat → loss of water + electrolytes → individual replacement strategy

The company uses sweat data to help estimate an athlete’s sodium losses and construct a personalized hydration strategy. It also provides an algorithm-based questionnaire/planner for people who cannot access an in-person sweat test. 3

This has allowed Precision to position itself as more than an electrolyte manufacturer. It presents itself as a hydration-planning company whose products are tools within a broader strategy.

Precision’s business has expanded significantly beyond its original hydration focus.

1. PH Electrolyte Range

The PH range is the core hydration line.

Current products include:

• PH 500
• PH 1000
• PH 1500
• Electrolyte tablets
• Electrolyte drink-mix packets
• Electrolyte capsules

The company sells both low-calorie effervescent tablets and powdered drink mixes.

The different formats allow athletes to separate hydration/electrolyte intake from calorie and carbohydrate intake, which is an important part of Precision’s overall endurance-nutrition philosophy.

2. PF Fueling Products

Precision eventually expanded from hydration into fueling, becoming Precision Fuel & Hydration.

Its current portfolio includes products such as:

• PF 30 Gel
• PF 30 Caffeine Gel
• PF 90 Gel
• PF 300 Flow Gel
• PF 30 Chew
• Carb & Electrolyte Drink Mix
• Carb Only Drink Mix

The company describes this expansion as a natural progression from helping athletes manage hydration to helping them manage the other major components of endurance nutrition—particularly carbohydrate intake.

3. Accessories and Supporting Products

The company also sells products such as:

• Bottles
• Soft flasks
• Strategy stickers
• Sample packs
• Personalized taster packs
• Educational courses

This reinforces the brand’s strategy of selling an overall endurance-performance system, rather than simply a sports drink.

Precision’s hydration products are deliberately positioned differently from conventional sugary sports drinks.

Its all-natural PH drink mixes contain sodium as the primary electrolyte and use a relatively small amount of carbohydrate. The company explains that glucose, together with sodium, can facilitate fluid absorption through the sodium-glucose co-transport mechanism.

The philosophy is essentially:

Hydration ≠ fueling.

An athlete may need:

• Water and sodium for hydration
• Carbohydrate for energy
• Additional food for calories

Those requirements can be adjusted independently.

This is particularly useful during long endurance events where consuming large amounts of carbohydrate through a drink can make it harder to control overall nutrition.

Precision states that its all-natural drink mixes are manufactured in the UK, while its effervescent tablets are produced in Germany and the United States and its SweatSalt Capsules are made in the UK.

The company also highlights Informed Sport / Informed Choice testing for its all-natural drink mixes and promotes its products as suitable for athletes concerned about prohibited substances.

Current product pages also identify characteristics such as:

• Vegan
• Low calorie (for relevant products)
• Gluten/dairy-free (for relevant products)
• No artificial ingredients (for the all-natural drink-mix range)
• Hypotonic formulations

These characteristics vary by product, so they should not automatically be assumed to apply to the entire portfolio.

One of the most important developments in the company’s history was its transition from Precision Hydration to Precision Fuel & Hydration.

Originally, the business was strongly focused on hydration and sodium replacement. As the company accumulated experience working with endurance athletes, it increasingly addressed the other major component of endurance performance: fueling.

That resulted in the PF product family and a broader brand proposition:

Precision Fuel & Hydration = fuel + fluids + electrolytes + personalized strategy.

This is why someone encountering the brand today may see substantially more than electrolyte tablets.

Precision states its personalized hydration services have been used by athletes and organizations across a wide range of professional sports.

Its stated client experience includes teams and athletes associated with:

• English Premier League football
• International rugby
• NFL
• NBA
• MLB
• NHL
• Formula 1
• MotoGP
• IndyCar
• Cycling
• Running
• Triathlon

It has also worked with groups outside conventional professional sports, including railway workers, firefighters, and military personnel exposed to significant heat stress.

This professional-sports exposure is an important part of the brand’s credibility and marketing positioning.

Andy Blow remains the key figure associated with the company’s creation and scientific philosophy. Precision describes him as its founder and a sports scientist with a background in endurance sport and Formula 1.

Jonny Tye is listed by the company as CEO. Tye was involved with Precision from its early days and previously competed in British Canoeing, including international-level competition.

The broader organization includes sports scientists, athlete-support personnel, professional-sport specialists, operations, marketing, and other functions.

The easiest way to understand Precision Hydration’s market positioning is to compare its philosophy with that of a conventional sports-drink company.

The company’s core competitive proposition is therefore personalization.

Its branding deliberately emphasizes the idea that athletes should “know your numbers” and choose products according to how they sweat.

Precision’s strongest association is with endurance sports.

Its natural customer base includes:

• Marathon runners
• Ultramarathoners
• Triathletes
• Cyclists
• Long-distance swimmers
• Adventure racers
• Serious recreational athletes
• Professional athletes

However, the products can also be relevant to people exercising in hot and humid environments, where sweat and electrolyte losses can become significant. Precision itself describes PH 1000, for example, as suitable for athletes with moderate-to-high sweat/sodium losses and people exercising in hotter or humid conditions.

Precision’s identity is quite different from mainstream sports-nutrition brands that focus heavily on flavor, lifestyle, and mass-market sports consumption.

Its branding tends to emphasize:

Science → personalization → performance → practicality.

The company’s communication combines sports-science terminology with a deliberately informal, sometimes humorous British personality. Its website uses a lot of conversational language while simultaneously presenting scientific material, athlete case studies, and research.

That combination gives the brand a distinctive personality: scientifically serious, but not overly clinical.

A major component of Precision’s identity is its attempt to connect products with sports science.

The company publishes educational material about:

• Sweat rate
• Sodium losses
• Dehydration
• Hyponatremia
• Cramping
• Carbohydrate fueling
• Endurance performance
• Heat
• Hydration planning

It also references published scientific work and maintains a database of athlete case studies.

An important caveat is that the existence of a scientific rationale does not mean every individual Precision recommendation is universally optimal for every athlete. Hydration and sodium requirements depend on exercise duration, intensity, environment, individual physiology, access to fluids, diet, and other factors. The company’s major proposition is personalization precisely because these variables differ.

If you had to explain Precision Hydration in one sentence:

Precision Hydration is a UK-founded sports-nutrition brand built around the idea that athletes should personalize their electrolyte and fluid intake according to how much they actually sweat and how much sodium they lose.

Precision Fuel & Hydration is a British sports-nutrition company founded in 2011 by sports scientist and endurance athlete Andy Blow. Originally known as Precision Hydration, the company developed around personalized sweat testing and electrolyte replacement, subsequently expanding into carbohydrate-based endurance fueling products. Its best-known hydration products are the PH 500, PH 1000, and PH 1500 electrolyte ranges, offered in tablet and drink-mix formats. The company provides hydration and fueling advice to recreational and professional athletes and has worked with organizations across endurance sport, team sports, and motorsport.
