Precision Hydration

To compete at our peak, we have to think about the details. Staying hydrated is key to performance, and the majority of us are using salt replacement tablets to replace the minerals lost through sweat during heavy exercise. For many of us however, the mineral content of these tablets isn’t enough to replace what we are losing.

The team at Precision Hydration believe it isn’t just how much we sweat that matters, but the composition – and we are all different. Everyone loses a different amount of sodium in their sweat, from as little as 200mg per litre of sweat to as much as 2,000mg per litre, so a ‘one-size-fits-all’ approach to hydration just doesn’t work.

If we aren’t replacing our lost salts quickly enough during long, intense exercise, we run the risk of underperformance, cramping, or potentially more dangerous conditions such as hyponatremia.


Precision Hydration run in-person sweat composition testing, as well as an online quiz to help estimate your salt loss. They also produce their own brand of hydration tablets called H2Prohydration to cater for athletes across the board.
