Precision's blister-packed capsules are ideal when you're relying on water from aid stations at events, if mixing up drinks during your longer activities isn't practical, or if you prefer plain water to even the mildest of sports drinks. They're also useful for topping up the electrolyte content of other drinks.

15 capsules per box, 250mg of sodium per capsule. Swallow with water.

• 15 swallowable capsules in a waterproof blister-pack, making them more convenient when carrying fluids is tricky
• Each capsule contains 250mg of sodium, making them stronger than most electrolyte capsules
• Enhances the absorption of water during physical exercise
• Formulated to aid fluid absorption, whilst being easy on the stomach
• Independently batch tested for a wide range of prohibited substances on the World Anti-Doping Agency (WADA) list

Swallow 1-3 capsules for every ~500ml of water you consume during sweaty exercise lasting more than about 90 minutes.
