FAQ's

Do I need to exercise as part of a sweat test?

No. The Precision Hydration method of sweat analysis uses a chemical to stimulate your sweat glands to contract in a small area of your forearm. Sweat from this area is collected (over a period of 5-15 minutes) and analyzed there and then, giving an immediate result.

Why do you test sweat from the forearm?

There is evidence to suggest that sweat samples taken from different parts of the body contain different sodium concentrations. However data shows that sweat from the forearm is an excellent indicator of the average sweat loss from a variety of sites and therefore represents whole body sweat losses accurately. See this article for more information

Do I need to take more than 1 sweat test?

No. Your sweat sodium level is genetically determined so varies very little over your lifetime. It may fall very slightly when you have spent time acclimatizing to a hot environment for several days but will return to your baseline level once you return to your normal environment.

Do H2Pro Hydrate drinks contain a source of energy/carbohydrates?

No. They are designed to be used in conjunction with energy gels, bars and other solid foods to provide the calories you need to perform over a prolonged period. Managing fluid, electrolyte and energy requirements independently of one another allows for fine tuning of these requirements based on ambient conditions, sweat rate and energy needs.

How do I know how much H2Pro Hydrate I need to drink?

Working out the amount you need to drink before during and after exercise is not an exact science. In general terms thirst and how often you are urinating are your best indicators of when you need to drink; if you are thirsty drink more, if you are urinating large volumes very frequently (and it is very clear in colour) you may be drinking too much. You can try weighing yourself before and after exercise to estimate fluid losses but remember that the temperature, clothing and how hard you are working will all change your sweat rate.

What flavour is H2Pro Hydrate?

All 4 products come in a light citrus fruit flavour which has been formulated and tested to be palatable even during intense exercise.

What is in H2Pro Hydate?

H2Pro Hydrate 250, 500, 1000 and 1500 contain 250, 500, 1000 and 1500mg of sodium per litre (when mixed as 1 tablet per 500ml) as the main ingredient. The sodium is delivered as sodium bicarbonate in 250, 500 and 1000 and as a mixture of sodium carbonate and sodium chloride in 1500.

All 4 drinks also contain potassium, magnesium and calcium in smaller amounts, similar to those lost in sweat as these do not tend to fluctuate from person to person as sodium does.

The other ingredients are:

Citric acid: acidifier which is for the effervescent reaction of the tablet, Maltodextrin and Sorbitol as binding agents for the tablets
Sucralose: for sweetening the drink
Saccharose: as a bulking agent and sweetener and Dextrose as a sweetener.

All of the ingredients are suitable for athletes to take and do not appear on the anti doping list.
