We believe that the most sophisticated piece of sports equipment you’ll ever own is your body. Science in Sport creates mechanics for the machinery of man. We’re the unseen force behind personal bests, world record and Olympic medals – SiS

There’s a reason why atheletes opt for Science in Sport to fuel their competition. They are ‘Informed Sport certified’ which means they are recognised for their robust testing system. What’s more, their extensive range of products tailored to each individual need-state makes staying at the top of your game as easy as SiS…


Carbohydrate is your body’s main fuel source for high intensity exercise, so it’s important to get them into your system BEFORE starting your workout. To deliver energy fast you need high GI carbohydrate that’s easy to take. Fat, fibre and protein slow down digestion prior to and during exercise. The GO Energy range from Science in Sport provides an easily digestible and quick supply of carbohydrate for energy.

A  major  cause  of  fatigue  in  endurance  exercise  is  depletion  of  carbohydrate energy  stores.  SiS  GO  Energy  provides  a  practical  solution  to  increase carbohydrate  intake  to  boost  our  muscle  glycogen  stores  prior  to  training  or competition.


Increased energy production during exercise causes your body temperature to go up. To keep cool we start to sweat more, and whilst all hot and bothered we lose both fluid and electrolytes, so drinking water alone just isn’t enough. The Science in Sport GO Hydro tablets and GO Electrolyte powders offer an easy solution to getting those much needed carbs and lost fluid back in every session.

In addition to ensuring optimal carbohydrate stores and hydration status before exercise, delivering additional carbohydrate and fluid during exercise is known to improve performance, race times and delay the onset of fatigue.


After exercise, your metabolic rate remains high for at least half an hour, making this the ideal time to replenish carb stores and rehydrate. Science in Sport recommends that you should drink 150% of fluid volume you lose during exercise as soon as you’ve finished. The Science in Sport rego rapid recovery provides rapidly digested carb, protein and electrolytes with the key vitamins and minerals your body needs to send to those tired muscles for recovery.
Rapid  replenishment  of  your  glycogen  stores  and  the  provision  of  protein
helps  you  to  get  the  most  from  your  training  and  prepare  you  for  your  next session.


After exercise, your immune system is weakened leaving you more vulnerable to coughs and colds. Vitamin C and Iron support the normal function of your immune system, and with an additional 200mg of Vit-C you’ll get that extra boost you need to help warn of those unwanted viruses.

SiS Immune is designed to support and maintain immune function during and after  exercise. As an effervescent tablet that readily dissolves in plain water, it represents a highly  practical approach to support your immune system after exercise.


Exercise increases the rate of protein breakdown, so essentially people that train more regularly need more protein. Whey protein is released far quicker than milk protein, and the Science in Sport protein range provides a delicious way of getting your protein fix whether before training or as part of your everyday diet. Whether you choose the gel, the powder, or one of their tasty protein bars, you can count on SiS when it comes to the growth and maintenance of lean muscle mass.

Vitamin  C and  Iron are known  to  contribute  to  the  maintenance  of  the  normal function  of  the  immune  system  during  and  after  intense  physical  exercise
in  addition  to  your  Recommended Daily Amount.
